Spring Boot转换web.xml侦听器

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?

回答:

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
