Springboot项目打包成war包

news 来源：原创 2025/5/2 8:20:03

1、首先创建一个springboot工程，然后我们改造启动类如：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@SpringBootApplication
public class AuroraWarApplication extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(AuroraWarApplication.class);
    }

    public static void main(String[] args) {
        SpringApplication.run(AuroraWarApplication.class, args);
    }

}

2、application.yml中不再需要配置上下文端口这些，简单配置个应用名

spring:
  application:
    name: aurora-war

3、修改pom文件

首先设置当前包打包为war

<artifactId>aurora-war</artifactId>
<name>aurora-war</name>
<description>Spring Boot to war</description>
<packaging>war</packaging>

其次修改对tomcat依赖的使用

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-tomcat</artifactId>
	<scope>provided</scope>
</dependency>
<dependency>
	<groupId>javax.servlet</groupId>
	<artifactId>javax.servlet-api</artifactId>
	<scope>provided</scope>
</dependency>
<dependency>
	<groupId>org.apache.tomcat.embed</groupId>
	<artifactId>tomcat-embed-el</artifactId>
	<scope>provided</scope>
</dependency>

最后修改<build>标签内容添加maven-war-plugin

<build>
	<plugins>
		<plugin>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-maven-plugin</artifactId>
		</plugin>
		<plugin>
			<groupId>org.apache.maven.plugins</groupId>
			<artifactId>maven-war-plugin</artifactId>
			<version>3.1.0</version>
			<configuration>
				<failOnMissingWebXml>false</failOnMissingWebXml>
				<warName>aurora-war</warName>
			</configuration>
		</plugin>
	</plugins>
</build>

4、使用idea简单测试下

先编写一个controller

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class IndexController {

    @GetMapping("/index")
    public String index(){
        return "index";
    }
}

idea中配置好本地tomcat路径和端口信息

配置需要部署的war包和上下文
