spring boot不使用内置tomcat

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。
