springboot 由 jar包转 war包

1.pom.xml文件中将jar改为war
2.在pom.xml的dependencies块中加入下面内容

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

3.增加类ServletInitializer，继承org.springframework.boot.context.web.SpringBootServletInitializer，重写configure方法，代码如下：

protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {      return application.sources(MicroserviceSimpleProviderUserApplication.class);  } 

其中MicroserviceSimpleProviderUserApplication类指的是以jar包形式启动的主类
