1、环境要求

环境：

  • IDEA
  • MySQL 5.1.47
  • Tomcat 9
  • Maven 3.9.9

要求：

  • 需要熟练掌握MySQL数据库，Spring，JavaWeb及MyBatis知识，简单的前端知识；

2、数据库环境

创建一个存放书籍数据的数据库表

CREATE DATABASE `ssmbuild`;USE `ssmbuild`;DROP TABLE IF EXISTS `books`;CREATE TABLE `books` (`bookID` INT(10) NOT NULL AUTO_INCREMENT COMMENT '书id',`bookName` VARCHAR(100) NOT NULL COMMENT '书名',`bookCounts` INT(11) NOT NULL COMMENT '数量',`detail` VARCHAR(200) NOT NULL COMMENT '描述',KEY `bookID` (`bookID`)
) ENGINE=INNODB DEFAULT CHARSET=utf8INSERT  INTO `books`(`bookID`,`bookName`,`bookCounts`,`detail`)VALUES 
(1,'Java',1,'从入门到放弃'),
(2,'MySQL',10,'从删库到跑路'),
(3,'Linux',5,'从进门到进牢');

3、基本环境搭建

1、新建一Maven项目！ssmbuild ， 添加web的支持

2、导入相关的pom依赖！

<dependencies><!--Junit--><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.13.2</version></dependency><!--数据库驱动--><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.47</version></dependency><!--数据库连接池--><dependency><groupId>com.mchange</groupId><artifactId>c3p0</artifactId><version>0.9.5.5</version></dependency><dependency><groupId>com.mchange</groupId><artifactId>mchange-commons-java</artifactId><version>0.2.19</version></dependency><!--Servlet - JSP--><dependency><groupId>javax.servlet</groupId><artifactId>servlet-api</artifactId><version>2.5</version></dependency><dependency><groupId>javax.servlet.jsp</groupId><artifactId>jsp-api</artifactId><version>2.1</version></dependency><dependency><groupId>javax.servlet</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency><!--Mybatis--><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>3.5.19</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>2.1.1</version></dependency><!--Spring--><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>5.2.0.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>5.2.0.RELEASE</version></dependency><!--lombok--><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><version>1.18.36</version></dependency></dependencies>

3、Maven资源过滤设置

<build><resources><resource><directory>src/main/java</directory><includes><include>**/*.properties</include><include>**/*.xml</include></includes><filtering>false</filtering></resource><resource><directory>src/main/resources</directory><includes><include>**/*.properties</include><include>**/*.xml</include></includes><filtering>false</filtering></resource></resources>
</build>

4、建立基本结构和配置框架！

  • com.lingbo.pojo

  • com.lingbo.dao

  • com.lingbo.service

  • com.lingbo.controller

  • mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration></configuration>

  • applicationContext.xml

    <?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd"></beans>

4、Mybatis层编写

1、数据库配置文件 database.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=false&useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=123456

2、IDEA关联数据库

3、编写MyBatis的核心配置文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration><typeAliases><package name="com.lingbo.pojo"/></typeAliases><mappers><mapper resource="com/lingbo/dao/BooksMapper.xml"/></mappers></configuration>

4、编写数据库对应的实体类 com.lingbo.pojo.Books

使用lombok插件！

package com.lingbo.pojo;import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;@NoArgsConstructor
@AllArgsConstructor
@Data
public class Books {private int bookID;private String bookName;private int bookCounts;private String detail;}

5、编写Dao层的 Mapper接口！

package com.lingbo.dao;import com.lingbo.pojo.Books;
import org.apache.ibatis.annotations.Param;import java.util.List;public interface BooksMapper {//增加一本Bookint addBook(Books books);//根据id删除一本Bookint deleteBookById(@Param("bookID") int id);//更新Bookint updateBook(Books books);//根据id查询BookBooks queryBookById(@Param("bookID") int id);//查询全部Books，返回list集合List<Books> queryAllBooks();//通过书籍名字查询信息Books queryBookByName(@Param("bookName") String bookName);}

6、编写接口对应的 Mapper.xml 文件。需要导入MyBatis的包；

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.lingbo.dao.BooksMapper"><!--增加一本Book--><insert id="addBook" parameterType="books">insert into ssmbuild.books (bookName, bookCounts, detail)values (#{bookName}, #{bookCounts}, #{detail});</insert><!--根据id删除一本Book--><delete id="deleteBookById" parameterType="_int">deletefrom ssmbuild.bookswhere bookID = #{bookID};</delete><!--更新Book--><update id="updateBook" parameterType="books">update ssmbuild.booksset bookName   = #{bookName},bookCounts = #{bookCounts},detail     = #{detail}where bookID = #{bookID};</update><!--根据id查询Book--><select id="queryBookById" parameterType="_int" resultType="books">select *from ssmbuild.bookswhere bookID = #{bookID};</select><!--查询全部Books，返回list集合--><select id="queryAllBooks" resultType="books">select *from ssmbuild.books;</select><!--通过书籍名字查询信息--><select id="queryBookByName" resultType="books">select *from ssmbuild.bookswhere bookName = #{bookName};</select></mapper>

7、编写Service层的接口和实现类

接口：

package com.lingbo.service;import com.lingbo.pojo.Books;import java.util.List;//BookService:底下需要去实现,调用dao层
public interface BooksService {//增加一本Bookint addBook(Books books);//根据id删除一本Bookint deleteBookById(int id);//更新Bookint updateBook(Books books);//根据id查询BookBooks queryBookById(int id);//查询全部Books，返回list集合List<Books> queryAllBooks();//通过书籍名字查询信息Books queryBookByName(String bookName);}

实现类：

package com.lingbo.service;import com.lingbo.dao.BooksMapper;
import com.lingbo.pojo.Books;import java.util.Collections;
import java.util.List;public class BooksServiceImpl implements BooksService {//调用dao层的操作，设置一个set接口，方便Spring管理private BooksMapper booksMapper;public void setBooksMapper(BooksMapper booksMapper) {this.booksMapper = booksMapper;}@Overridepublic int addBook(Books books) {return booksMapper.addBook(books);}@Overridepublic int deleteBookById(int id) {return booksMapper.deleteBookById(id);}@Overridepublic int updateBook(Books books) {return booksMapper.updateBook(books);}@Overridepublic Books queryBookById(int id) {return booksMapper.queryBookById(id);}@Overridepublic List<Books> queryAllBooks() {return booksMapper.queryAllBooks();}@Overridepublic Books queryBookByName(String bookName) {return booksMapper.queryBookByName(bookName);}
}

OK，到此，底层需求操作编写完毕！

5、Spring层

1、配置Spring整合MyBatis，我们这里数据源使用c3p0连接池；

2、我们去编写Spring整合Mybatis的相关的配置文件；spring-dao.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttps://www.springframework.org/schema/context/spring-context.xsd"><!-- 配置整合mybatis --><!-- 1.关联数据库文件 --><context:property-placeholder location="classpath:database.properties"/><!-- 2.数据库连接池 --><!--数据库连接池
dbcp  半自动化操作  不能自动连接
c3p0  自动化操作（自动的加载配置文件 并且设置到对象里面）
--><bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"><!-- 配置连接池属性 --><property name="driverClass" value="${jdbc.driver}"/><property name="jdbcUrl" value="${jdbc.url}"/><property name="user" value="${jdbc.username}"/><property name="password" value="${jdbc.password}"/><!-- c3p0连接池的私有属性 --><property name="maxPoolSize" value="30"/><property name="minPoolSize" value="10"/><!-- 关闭连接后不自动commit --><property name="autoCommitOnClose" value="false"/><!-- 获取连接超时时间 --><property name="checkoutTimeout" value="10000"/><!-- 当获取连接失败重试次数 --><property name="acquireRetryAttempts" value="2"/></bean><!-- 3.配置SqlSessionFactory对象 --><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><!-- 注入数据库连接池 --><property name="dataSource" ref="dataSource"/><!-- 配置MyBaties全局配置文件:mybatis-config.xml --><property name="configLocation" value="classpath:mybatis-config.xml"/></bean><!-- 4.配置扫描Dao接口包，动态实现Dao接口注入到spring容器中 --><!--解释 ：https://www.cnblogs.com/jpfss/p/7799806.html--><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><!-- 注入sqlSessionFactory --><property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/><!-- 给出需要扫描Dao接口包 --><property name="basePackage" value="com.lingbo.dao"/></bean></beans>

3、Spring整合service层

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:context="http://www.springframework.org/schema/context"xmlns:jdbc="http://www.springframework.org/schema/jdbc"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/jdbchttp://www.springframework.org/schema/jdbc/spring-jdbc.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx.xsd"><!-- 扫描service相关的bean --><context:component-scan base-package="com.lingbo.service"/><!--BookServiceImpl注入到IOC容器中--><bean id="BooksServiceImpl" class="com.lingbo.service.BooksServiceImpl"><property name="booksMapper" ref="booksMapper"/></bean><!-- 配置事务管理器 --><bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><!-- 注入数据库连接池 --><property name="dataSource" ref="dataSource"/></bean></beans>

Spring层搞定！再次理解一下，Spring就是一个大杂烩，一个容器！对吧！

6、SpringMVC层

1、web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"version="4.0"><!--DispatcherServlet--><servlet><servlet-name>DispatcherServlet</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><!--一定要注意:我们这里加载的是总的配置文件，之前被这里坑了！--><param-value>classpath:applicationContext.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>DispatcherServlet</servlet-name><url-pattern>/</url-pattern></servlet-mapping><!--encodingFilter--><filter><filter-name>encodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>utf-8</param-value></init-param></filter><filter-mapping><filter-name>encodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><!--Session过期时间--><session-config><session-timeout>15</session-timeout></session-config></web-app>

2、spring-mvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/mvchttps://www.springframework.org/schema/mvc/spring-mvc.xsd"><!-- 配置SpringMVC --><!-- 1.开启SpringMVC注解驱动 --><mvc:annotation-driven/><!-- 2.静态资源默认servlet配置--><mvc:default-servlet-handler/><!-- 3.配置jsp 显示ViewResolver视图解析器 --><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/><property name="prefix" value="/WEB-INF/jsp/"/><property name="suffix" value=".jsp"/></bean><!-- 4.扫描web相关的bean --><context:component-scan base-package="com.lingbo.controller"/></beans>

3、Spring配置整合文件，applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd"><import resource="spring-dao.xml"/><import resource="spring-service.xml"/><import resource="spring-mvc.xml"/></beans>

配置文件，暂时结束！Controller 和 视图层编写

1、BooksController 类编写 ， 方法一：查询全部书籍

@Controller
@RequestMapping("/books")
public class BooksController {@Autowired@Qualifier("BooksServiceImpl")private BooksService booksService;@RequestMapping("/allBooks")public String allBooks(Model model) {List<Books> books = booksService.queryAllBooks();model.addAttribute("list", books);return "allBooks";}}

2、编写首页 index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
<!DOCTYPE HTML>
<html>
<head><title>首页</title><style type="text/css">a {text-decoration: none;color: black;font-size: 18px;}h3 {width: 180px;height: 38px;margin: 100px auto;text-align: center;line-height: 38px;background: deepskyblue;border-radius: 4px;}</style>
</head>
<body><h3><a href="${pageContext.request.contextPath}/books/allBooks">点击进入列表页</a>
</h3>
</body>
</html>

3、书籍列表页面 allBooks.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head><title>书籍列表</title><meta name="viewport" content="width=device-width, initial-scale=1.0"><!-- 引入 Bootstrap --><link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
<body><div class="container"><div class="row clearfix"><div class="col-md-12 column"><div class="page-header"><h1><small>书籍列表 —— 显示所有书籍</small></h1></div></div></div><div class="row"><div class="col-md-4 column"><a class="btn btn-primary" href="${pageContext.request.contextPath}/books/toAddBook">新增</a><a class="btn btn-primary" href="${pageContext.request.contextPath}/books/allBooks">显示全部书籍</a></div><div class="col-lg-8 column text-right"><%--查询书籍--%><form action="${pageContext.request.contextPath}/books/queryBook" method="post" style="float: right;" class="form-inline"><span style="color: red;font-weight: bold;">${error}</span><input type="text" name="queryBookName" placeholder="请输入要查询的书籍名称"class="form-control"/><input type="submit" value="查询" class="btn btn-primary" style="right: auto"/></form></div></div><div class="row clearfix"><div class="col-md-12 column"><table class="table table-hover table-striped"><thead><tr><th>书籍编号</th><th>书籍名字</th><th>书籍数量</th><th>书籍详情</th><th>操作</th></tr></thead><tbody><c:forEach var="book" items="${requestScope.get('list')}"><tr><td>${book.getBookID()}</td><td>${book.getBookName()}</td><td>${book.getBookCounts()}</td><td>${book.getDetail()}</td><td><a href="${pageContext.request.contextPath}/books/toUpdateBook?id=${book.getBookID()}">更改</a>|<a href="${pageContext.request.contextPath}/books/del/${book.getBookID()}">删除</a></td></tr></c:forEach></tbody></table></div></div>
</div>

4、BookController 类编写 ， 方法二：添加书籍

@Controller
@RequestMapping("/books")
public class BooksController {@RequestMapping("/toAddBook")public String toAddBook() {return "addBook";}@RequestMapping("/addBook")public String addBook(Books books) {System.out.println(books);booksService.addBook(books);return "redirect:/books/allBooks";}}

5、添加书籍页面：addBook.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %><html>
<head><title>新增书籍</title><meta name="viewport" content="width=device-width, initial-scale=1.0"><!-- 引入 Bootstrap --><link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<div class="container"><div class="row clearfix"><div class="col-md-12 column"><div class="page-header"><h1><small>新增书籍</small></h1></div></div></div><form action="${pageContext.request.contextPath}/books/addBook" method="post">书籍名称：<input type="text" name="bookName"><br><br><br>书籍数量：<input type="text" name="bookCounts"><br><br><br>书籍详情：<input type="text" name="detail"><br><br><br><input type="submit" value="添加"></form></div>

6、BookController 类编写 ， 方法三：修改书籍

@Controller
@RequestMapping("/books")
public class BooksController {@RequestMapping("/toUpdateBook")public String toUpdateBook(Model model, int id) {Books books = booksService.queryBookById(id);System.out.println(books);model.addAttribute("book", books);return "updateBook";}@RequestMapping("/updateBook")public String updateBook(Model model, Books book) {System.out.println(book);booksService.updateBook(book);Books books = booksService.queryBookById(book.getBookID());model.addAttribute("books", books);return "redirect:/books/allBooks";}}

7、修改书籍页面 updateBook.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head><title>修改信息</title><meta name="viewport" content="width=device-width, initial-scale=1.0"><!-- 引入 Bootstrap --><link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<div class="container"><div class="row clearfix"><div class="col-md-12 column"><div class="page-header"><h1><small>修改信息</small></h1></div></div></div><form action="${pageContext.request.contextPath}/books/updateBook" method="post"><input type="hidden" name="bookID" value="${book.getBookID()}"/>书籍名称：<input type="text" name="bookName" value="${book.getBookName()}"/>书籍数量：<input type="text" name="bookCounts" value="${book.getBookCounts()}"/>书籍详情：<input type="text" name="detail" value="${book.getDetail() }"/><input type="submit" value="提交"/></form></div>

8、BookController 类编写 ， 方法四：删除书籍

@Controller
@RequestMapping("/books")
public class BooksController {@RequestMapping("/del/{bookId}")public String deleteBook(@PathVariable("bookId") int id) {booksService.deleteBookById(id);return "redirect:/books/allBooks";}}

9、BookController 类编写 ， 方法五：通过书名查询书籍

@Controller
@RequestMapping("/books")
public class BooksController {//查询书籍@RequestMapping("/queryBook")public String queryBook(String queryBookName, Model model) {Books books = booksService.queryBookByName(queryBookName);List<Books> booksList = new ArrayList<Books>();booksList.add(books);if (books == null){booksList = booksService.queryAllBooks();model.addAttribute("error","未查到");}model.addAttribute("list", booksList);return "allBooks";}}

配置Tomcat，进行运行！

到目前为止，这个SSM项目整合已经完全的OK了，可以直接运行进行测试！
