SpringBoot在Tomcat部署war包

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

        war

移除内置Tomcat

        
            org.springframework.boot
            spring-boot-starter-tomcat
            provided
        

WebSocket错误

        
            javax.servlet
            javax.servlet-api
            3.1.0
            provided
        

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

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
