修改pom.xml:
<packaging>war</packaging><dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> <scope>provided</scope> </dependency>修改启动类：
继承SpringbootServletInitializer,并实现configure方法。
@SpringBootApplication public class MyblogApplication extends SpringBootServletInitializer { public static void main(String[] args) { SpringApplication.run(MyblogApplication.class, args); } // 外置tomcat需要添加 @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) { return builder.sources(MyblogApplication.class); } }如果使用了websocket，注释websocket配置
ServerEndpointExporter。
