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

   <packaging>war</packaging>

2. 移除springboot web模块中自带的tomcat

   <dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-web</artifactId>            
           <exclusions>
               <exclusion>
                   <artifactId>spring-boot-starter-tomcat</artifactId>
                   <groupId>org.springframework.boot</groupId>
               </exclusion>
           </exclusions>
   </dependency>

3. 在pom文件中添加servlet的依赖

   <dependency>
       <groupId>javax.servlet</groupId>
       <artifactId>javax.servlet-api</artifactId>
   </dependency>

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
