我正在尝试将我的项目转换为Spring Boot项目(嵌入了Jetty的可执行jar文件)。都可以使用标准示例,但是我想将旧的web.xml迁移到Spring Boot。
我迁移了Servlet和过滤器,但是我不了解如何迁移过滤器,如下所示:
<listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <listener> <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class> </listener> <listener> <listener-class>org.granite.config.GraniteConfigListener</listener-class> </listener> <listener> <listener-class>org.granite.gravity.websocket.GravityWebSocketDeployer</listener-class> </listener>
我创建了@SpringBootApplication类,并在所有配置中进行了编写:
@Bean @Order(1) public FilterRegistrationBean springSecurityFilterChain() { FilterRegistrationBean filterRegBean = new FilterRegistrationBean(); DelegatingFilterProxy delegatingFilterProxy = new DelegatingFilterProxy(); filterRegBean.setFilter(delegatingFilterProxy); List<String> urlPatterns = new ArrayList<String>(); urlPatterns.add("/*"); filterRegBean.setUrlPatterns(urlPatterns); return filterRegBean; }
有人可以向我解释如何转换监听器?
对于RequestContext请阅读以下内容
@Bean @ConditionalOnMissingBean(RequestContextListener.class) public RequestContextListener requestContextListener() { return new RequestContextListener(); }
对于另一个侦听器,当您使用spring-boot时,该链接会自动注册。
对于您自己的听众。
public class MyAdditionListeners extends SpringBootServletInitializer { protected final Log logger = LogFactory.getLog(getClass()); @Override public void onStartup(ServletContext servletContext) throws ServletException { WebApplicationContext rootAppContext = createRootApplicationContext(servletContext); if (rootAppContext != null) { servletContext.addListener(new YourListenerHere()); } else { this.logger.debug("No ContextLoaderListener registered, as " + "createRootApplicationContext() did not " + "return an application context"); } }
最后一个链接,您可以在其中找到有关侦听器和SpringApplication类的信息。阅读部分
