大家好，又见面了，我是你们的朋友全栈君。

启动类配置

继承SpringBootServletInitializer

@SpringBootApplication
public class TestApplication extends SpringBootServletInitializer { 
   
    public static void main(String[] args) { 
   
        SpringApplication.run(TestApplication.class, args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { 
   
        return application.sources(TestApplication.class);
    }
}

打包方式配置

		<packaging>war</packaging>

移除内置Tomcat

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
            <scope>provided</scope>
        </dependency>

WebSocket错误

        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
            <version>3.1.0</version>
            <scope>provided</scope>
        </dependency>

Bean按需加载

@Configuration
public class WebSocketConfig { 
   
    @Bean
    @ConditionalOnProperty(name = "system.package", havingValue = "jar", matchIfMissing = true)
    public ServerEndpointExporter serverEndpointExporter() { 
   
        return new ServerEndpointExporter();
    }
}

Tomcat设置

Host节点增加Context可以直接通过ip+端口方式访问，需要将appBase清除，防止启动两次应用

<Host name="localhost" appBase="" unpackWARs="true" autoDeploy="true">
		<Context path="" docBase="webapps/test" reloadable="false"/>
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log" suffix=".txt" pattern="%h %l %u %t &quot;%r&quot; %s %b" />

</Host>

注意事项

对于框架封装引用jar包，需要注意工程项目中只能有一个类继承自SpringBootServletInitializer，否则会导致ApplicationContext初始化两次
