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。
