1.在pom.xml里修改或者添加packaging,值为war

2.在pom.xml里添加依赖

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-tomcat</artifactId>

<scope>compile</scope>

</dependency>

3.修改工程的启动类

@SpringBootApplication

public class ParserinterfaceApplicationextends SpringBootServletInitializer

        implements WebApplicationInitializer{

        @Override

          protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {

                return application.sources(ParserinterfaceApplication.class);

        }

        public static void main(String[] args) {

                SpringApplication.run(ParserinterfaceApplication.class, args);

        }

}
