Spring引导转换web.xml监听器

我正在尝试将我的项目转换为Spring Boot项目(嵌入Jetty的可执行jar文件).所有工作都使用标准示例,但我希望将旧的web.xml迁移到Spring Boot.

我迁移了Servlet和过滤器,但我不明白如何迁移过滤器:

    org.springframework.web.context.ContextLoaderListener


    org.springframework.web.context.request.RequestContextListener


    org.granite.config.GraniteConfigListener 
 
    
    org.granite.gravity.websocket.GravityWebSocketDeployer

我创建了@SpringBootApplication类,并在所有配置中编写:

@Bean
@Order(1)
public FilterRegistrationBean springSecurityFilterChain() {     
    FilterRegistrationBean filterRegBean = new FilterRegistrationBean();
    DelegatingFilterProxy delegatingFilterProxy = new DelegatingFilterProxy();
    filterRegBean.setFilter(delegatingFilterProxy);
    List urlPatterns = new ArrayList();
    urlPatterns.add("/*");
    filterRegBean.setUrlPatterns(urlPatterns);
    return filterRegBean;
}

有人可以解释我应该如何转换听众？

Spring Boot将@Beans使用servlet容器自动注册以下任何类型:

ServletContextAttributeListener

ServletRequestListener

ServletRequestAttributeListener

HttpSessionAttributeListener

HttpSessionListener

的ServletContextListener

例如,要注册GravityWebSocketDeployer哪个是向配置类ServletContextListener添加@Bean方法:

@Bean
public GravityWebSocketDeployer gravityWebSocketDeployer() {
    return new GravityWebSocketDeployer();
}
