springboot打war包步骤，放tomcat下执行不成功一（war包部署）

springboot打war包
1、在pom.xml文件的中添加打包方式

 	<groupId>****</groupId>
    <artifactId>****</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>****</name>
    <packaging>war</packaging>

2、排除内置的Tomcat容器，加上tomcat依赖（编译时排除，不加这个，项目中servlet会报错）：

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

3、org.springframework.boot.web.servlet.support.SpringBootServletInitializer，实现configure方法（可实现可不实现）

@SpringBootApplication
public class TestApplication extends SpringBootServletInitializer {

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

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(TestApplication .class);
    }
}

4、maven命令打包

clean

war包方式
mvn clean package -Dmaven.test.skip=true

jar包方式
mvn clean install -Dmaven.test.skip=true

其中 clean是清除之前的包，-Dmaven.test.skip=true是忽略测试代码
