容器化 Spring Boot 应用程序
1.建立项目目录
[root@host1 tomcat-mysql]# cd
[root@host1 ~]# cd
[root@host1 ~]# mkdir -p spring-boot
[root@host1 ~]# mkdir -p spring-boot/app/src/main/java/com/abc/hello
[root@host1 ~]# mkdir -p spring-boot/nginx/conf.d2.准备 Spring Boot 应用程序代码
[root@host1 ~]# cat spring-boot/app/src/main/java/com/abc/hello/Application.java
package com.abc.hello;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;@Configuration
@EnableAutoConfiguration
@ComponentScan
public class Application {public static void main(String[] args) {ApplicationContext ctx = SpringApplication.run(Application.class, args);}
}
[root@host1 ~]# vi spring-boot/app/src/main/java/com/abc/hello/HelloController.java
[root@host1 ~]# cat spring-boot/app/src/main/java/com/abc/hello/HelloController.java
package com.abc.hello;import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.bind.annotation.RequestMapping;@RestController
public class HelloController {@RequestMapping("/")public String index() {return "Hello, Spring Boot!\n";}
}
[root@host1 ~]# vi spring-boot/app/pom.xml
[root@host1 ~]# cat spring-boot/app/pom.xml
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.abc</groupId><artifactId>hello</artifactId><version>0.1-SNAPSHOT</version><!-- Spring Boot 父工程依赖 --><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.2.0.RELEASE</version></parent><dependencies><!-- Web 应用核心依赖 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><!-- 开发热部署依赖（可选，方便修改代码后自动重启） --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-devtools</artifactId><optional>true</optional></dependency><!-- MySQL 连接器（示例包含，若不需要可暂时注释） --><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId></dependency></dependencies><!-- Maven 打包插件 --><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build>
</project>
[root@host1 ~]# vi spring-boot/app/Dockerfile
[root@host1 ~]# cat spring-boot/app/Dockerfile
FROM maven:3.8-jdk-83.提供 Nginx 配置文件
[root@host1 ~]# vi spring-boot/nginx/conf.d/app.conf
[root@host1 ~]# cat spring-boot/nginx/conf.d/app.conf
server {listen 80; # 监听 80 端口（外部访问端口）charset utf-8;access_log off; # 关闭访问日志（可选，简化输出）location / {# 转发请求到 Spring Boot 服务（服务名“app”由 Compose 维护）proxy_pass http://app:8080;proxy_set_header Host $host:$server_port;proxy_set_header X-Forwarded-Host $server_name;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;}# 静态资源配置（示例，若无需静态资源可暂时注释）location /static {access_log off;expires 30d; # 静态资源缓存 30 天alias /app/static;}
}4.在项目根目录下创建名为 compose.yaml 的 Compose 文件
[root@host1 ~]# vi spring-boot/compose.yaml
[root@host1 ~]# cat spring-boot/compose.yaml
services:# 1. Nginx 服务：反向代理 + 暴露 80 端口nginx:container_name: spbt-nginximage: nginx:1.16restart: always # 容器异常时自动重启ports:- "80:80" # 主机 80 端口 → 容器 80 端口- "443:443" # HTTPS 端口（示例预留，可暂不关注）volumes:# 本地 Nginx 配置 → 容器内 Nginx 配置目录- ./nginx/conf.d:/etc/nginx/conf.ddepends_on:- app # 确保 Nginx 在 Spring Boot 服务后启动# 2. MySQL 服务：数据库存储mysql:container_name: spbt-mysqlimage: mysql/mysql-server:8.0environment:MYSQL_DATABASE: test # 初始化数据库名MYSQL_ROOT_PASSWORD: root # root 用户密码MYSQL_ROOT_HOST: '%' # 允许任意主机连接 rootLANG: C.UTF-8 # 字符集配置ports:- "3306:3306" # 主机 3306 端口 → 容器 3306 端口（可选，方便外部连接）volumes:- mysql-data:/var/lib/mysql # 持久化 MySQL 数据restart: always# 3.
