1. 相應(yīng)模塊的pom.xml中project節(jié)點(diǎn)下增加或修改打包方式(不要修改父模塊)

<packaging>war</packaging>

2.pom.xml中dependencies節(jié)點(diǎn)下增加或修改tomcat相關(guān)包配置

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>    <!-- 表明該包只在編譯和測試的時候用 -->
</dependency>

3.pom.xml中build節(jié)點(diǎn)下增加或修改打包文件名(非必要)

<finalName>messagerouter</finalName>

4.修改Application類,需要繼承SpringBootServletInitializer,重寫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.最后執(zhí)行mvn package就可以直接生成war包了.

附完整pom.xml:
