IDEA将多模块项目打包成jar包或者war包

一、打包成jar包

1、在web层pom中添加打包插件

     
         
             org.springframework.boot
             spring-boot-maven-plugin
         
     
 

2、父模块打包方式改为pom，其他模块改为jar

3、点击右侧Maven Project，找到父模块下Lifecycle，双击clean完成后package，打包成jar包在web层target目录下

二、打包成war包

1、web层pom打包插件如下：

	
		
			org.apache.maven.plugins
			maven-war-plugin
			3.2.0
		
	

2、将web层打包方式改为war

3、去除web层内置tomcat服务器依赖

	org.springframework.boot
	spring-boot-starter-web
	
		
			org.springframework.boot
			spring-boot-starter-tomcat
		
	

4、添加对外置tomcat支持

	org.springframework.boot
	spring-boot-starter-tomcat
	provided

5、修改主方法，添加继承SpringBootServletInitializer并重写

@SpringBootApplication
@ComponentScan(basePackages = "com.ouyin")
@MapperScan(basePackages = "com.ouyin.dao")
public class WebApplication extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(WebApplication.class);
    }

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

}
