SpringBoot项目打包成war

SpringBoot项目默认是打包成jar,如果我们想把SpringBoot项目打包成war,可以按照以下步骤就行操作:

1. 在pom文件中修改打包方式为war

   war

2. 移除springboot web模块中自带的tomcat

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

3. 在pom文件中添加servlet的依赖

   
       javax.servlet
       javax.servlet-api
   

4. 在Application启动类同一包下面新建WarStarterApplication类,继承SpringBootServletInitializer类,并重写configure方法

   public class WarStarterApplication extends SpringBootServletInitializer {
       @Override
       protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
           //指向Application启动类
           return builder.sources(Application.class);
       }
   }

5. maven install即可打包成war
