interceptor

Is it possible to apply an interceptor to all controllers and actions, except some that are defined? Just to be clear, I am not interested in applying an interceptor on a list of defined ones. I want to define those to exclude. Thanks! Since Spring 3.2 they added that feature with the tag mvc:exclude-mapping See this example from the Spring documentation: <mvc:interceptors> <bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor" /> <mvc:interceptor> <mvc:mapping path="/**"/> <mvc:exclude-mapping path="/admin/**"/> <bean class="org.springframework.web.servlet.theme

How to add multiple, independent HTTP interceptors to an Angular 4 application? I tried to add them by extending the providers array with more than one interceptors. But only the last one is actually executed, Interceptor1 is ignored. @NgModule({ declarations: [ /* ... */ ], imports: [ /* ... */ HttpModule ], providers: [ { provide: Http, useFactory: (xhrBackend: XHRBackend, requestOptions: RequestOptions) => new Interceptor1(xhrBackend, requestOptions), deps: [XHRBackend, RequestOptions], }, { provide: Http, useFactory: (xhrBackend: XHRBackend, requestOptions: RequestOptions) => new

SpringBoot 确实为我们做了很多事情， 但有时候我们想要自己定义一些Handler，Interceptor，ViewResolver，MessageConverter，该怎么做呢。在Spring Boot 1.5版本都是靠重写WebMvcConfigurerAdapter的方法来添加自定义拦截器，消息转换器等。SpringBoot 2.0 后，该类被标记为@Deprecated。因此我们只能靠实现WebMvcConfigurer接口来实现。接下来让我们来看看这个接口类吧！（列举下常用的方法供参考） package com.developlee.config; import com.alibaba.fastjson.serializer.SerializerFeature; import com.alibaba.fastjson.support.config.FastJsonConfig; import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter; import com.developlee.configurer.USLocalDateFormatter; import org.springframework.format.FormatterRegistry; import org

I am using Struts 2 in my web application. I write code to check user session into interceptor but while I am returning net.sf.json.JSONObject as response, its reset the response object and set null to the object. Please check my code. import net.sf.json.JSONObject; import com.opensymphony.xwork2.interceptor.Interceptor; public class AuthorizationInterceptor implements Interceptor { JSONObject response = new JSONObject(); public String intercept(ActionInvocation invocation) { try { Map session = invocation.getInvocationContext().getSession(); if (session.get("userId") == null) { response.put(

I want to use interceptors in a Java-SE application and I am using weld as CDI implementation and i'm testing this here: The Main-Class: public static void main(String[] args) { WeldContainer weldContainer = new Weld().initialize(); Service service = weldContainer.instance().select(Service.class).get(); service.methodCall(); service.methodCallNumberTwo(); } The Service-Class: public class Service { @TestAnnotation public void methodCall(){ System.out.println("methodCall...!"); methodCallNumberTwo(); } @TestAnnotation public void methodCallNumberTwo(){ System.out.println("methodCallNumberTwo...

In Struts 2 version 2.3.28, the i18n interceptor only accepts the locales which are registered to jvm, the list which is returned by Locale.getAvailableLocales() . Well, although I can extend the list of available Java Locales, as mentioned How to extend the list of available Java Locales , is it any short way that set this interceptor to accept all strings as locale (for example fa_IR ) ?! Just a note: Setting the default locale to fa_IR ( <constant name="struts.locale" value="fa_IR" /> ) works fine. No, you have to create your own interceptor that extends i18n and override this method

In the following action class, I'm using the parameters interceptor. @Namespace("/admin_side") @ResultPath("/WEB-INF/content") @ParentPackage(value = "struts-default") @InterceptorRefs(@InterceptorRef(value="store", params={"operationMode", "AUTOMATIC"})) public final class TestAction extends ActionSupport implements Serializable, ValidationAware, Preparable { private static final long serialVersionUID = 1L; private String param1; private String param2; //Getters and setters. public TestAction() {} @Action(value = "TestMessage", results = { @Result(name=ActionSupport.SUCCESS, type=

前言 小伙伴们应该听说过 过滤器、拦截器、切面 ，印象上都 能够起到截断拦截的作用 ，在做一些业务需求时， 不知道如何选择 ，今天老顾就来介绍一下他们之间的区别。 Filter过滤器 过滤器可以 拦截到方法的请求和响应 (ServletRequest request, ServletResponse response),并对 请求响应 做出过滤操作。 过滤器 依赖于servlet容器 。在实现上，基于函数回调，它可以对几乎所有请求进行过滤，一个过滤器实例只能在 容器初始化时调用一次。 使用过滤器的目的是用来 做一些过滤操作 ，获取我们想要获取的数据，比如：在过滤器中修改字符编码；在 过滤器中修改HttpServletRequest的一些参数 ，包括：过滤低俗文字、危险字符等。 话不多说，先上代码 再定义两个Controller，一个UserController，一个OrderController 虽然Filter过滤器和Controller请求都已经定义了，但现在过滤器是不起作用的。需要把Filter配置一下，有两个方案 第一个方案在Filter上面加上 @Component @Component public class TimeFilter implements Filter 第二个方案配置化注册过滤器 第二个方案的特点就是可以 细化到过滤哪些规则的URL 我们来 启动应用时
