Spring Boot改为打war包方式

1. 相应模块的pom.xml中project节点下增加或修改打包方式(不要修改父模块)

<packaging>war</packaging>

2.pom.xml中dependencies节点下增加或修改tomcat相关包配置

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>    <!-- 表明该包只在编译和测试的时候用 -->
</dependency>

3.pom.xml中build节点下增加或修改打包文件名(非必要)

<finalName>messagerouter</finalName>

4.修改Application类,需要继承SpringBootServletInitializer,重写configure方法

@SpringBootApplication
public class MessageRouterApplication extends SpringBootServletInitializer {

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

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

5.最后执行mvn package就可以直接生成war包了.

附完整pom.xml:
