springboot打war包

1. 修改打包方式，在pom文件中添加

   <packaging>war</packaging>

   //...
   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-web</artifactId>
       <!-- 打包部署到tomcat上面时，不需要打包tmocat相关的jar包，否则会引起jar包冲突 -->
       <exclusions>
           <exclusion>
               <groupId>org.springframework.boot</groupId>
               <artifactId>spring-boot-starter-tomcat</artifactId>
           </exclusion>
       </exclusions>
   </dependency>
   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-tomcat</artifactId>
       <scope>provided</scope>
   </dependency>
   //...
   <build>
       <plugins>
           <plugin>
               <groupId>org.springframework.boot</groupId>
               <artifactId>spring-boot-maven-plugin</artifactId>
           </plugin>
       </plugins>
   </build>
   

2. 修改项目的启动类为

   @SpringBootApplication
   public class BlogApplication extends SpringBootServletInitializer {
   
       public static void main(String[] args) {
           SpringApplication.run(BlogApplication.class, args);
       }
   
       @Override
       protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
           return builder.sources(BlogApplication.class);
       }
   }
   
   

3. 使用maven打包(跳过测试)

   mvn install -Dmaven.test.skip=true
