启动类配置

继承SpringBootServletInitializer

@SpringBootApplicationpublic 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);    }}

打包形式配置

        <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谬误

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

Bean按需加载

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

Tomcat设置

Host节点减少Context能够间接通过ip+端口形式拜访，须要将appBase革除，避免启动两次利用

<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

对于框架封装援用jar包，须要留神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
