interceptor

This question already has an answer here : Why is the interceptor not called in the same service class? (1 answer) Closed 3 years ago . I'm using CDI Interceptors and I've realized that only the first method call in a class annotated with @Interceptor is intercepted. In the example below methodB is never intercepted. @InterceptorBinding @Target(ElementType.TYPE) @Retention(RetentionPolicy.RUNTIME) public @interface Transactional { } @Transactional @Interceptor public class TransactionsInterceptor { @AroundInvoke public Object transactionInterceptor(InvocationContext context) throws Exception {

I know one can use interceptors before a method call by using the @AroundInvoke annotation. What I would like to do is execute certain code after the method call, so that I can for example create a log entry before and after a method execution. Is this possible with EJB3, or do I need to use AOP? @AroundInvoke interceptor is passed InvocationContext, and proceed() must be called to advance the method. Thus: @AroundInvoke public Object log(InvocationContext ic) throws Exception { logEntry(); try { return ic.proceed(); } finally { logExit(); } } Depending on your needs, you could also log the

I have spring application(I haven't lazy beans). I want to insert logic to place when all @Component(@Repositoey @Service @Controller) beans are initialized. How can I make it? trf As mentioned in the answer to this question , you could use ApplicationListener and look for the ContextRefreshedEvent : public class Loader implements ApplicationListener<ContextRefreshedEvent>{ public void onApplicationEvent(ContextRefreshedEvent event) { // whatever you want to do when app context is initialized or refreshed } } 来源： https://stackoverflow.com/questions/19541600/catch-moment-when-spring-initialized

i wanted to exclude some services using interceptor. app.module.js providers: [ UserService, RolesService, { provide: HTTP_INTERCEPTORS, useClass: TokenInterceptor, multi: true }, ], Login.service.ts return this.httpClient.post(this.appUrl + '/oauth/token', body.toString(), { headers, observe: 'response' }) .map((res: Response) => { const response = res.body; this.storeToken(response); return response; }) .catch((error: any) => { ErrorLogService.logError(error); return Observable.throw(new Error(error.status)); }); } To give this an answer not only in comments as requested ;-) To exclude some

接手了一个老项目，用的是spring 1.2.9的，配置aop怎么也不起作用，在网上搜了半天，只能啃官方文档。 https://docs.spring.io/spring/docs/1.2.9/reference/aop.html 不知道为什么，必须加上 DefaultAdvisorAutoProxyCreator 才起作用 <bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"/> <bean id="interceptor" class="com.alibaba.druid.support.spring.stat.DruidStatInterceptor"/> <bean id="settersAndAbsquatulateAdvisor" class="org.springframework.aop.support.RegexpMethodPointcutAdvisor"> <property name="advice"> <ref local="interceptor"/> </property> <property name="patterns"> <list> <value>com.my.service.*</value> </list> <

Trying to implement solution for displaying a loading indicator when requests are in progress. Looking from this solution I implemented the interceptor with the service. All works fine, except the counter is not deceasing becase the .do() callback never gets executed ( b is never printed in the console). Any thoughts on that? How to know if request has finished? import { Injectable } from '@angular/core'; import { HttpEvent, HttpInterceptor, HttpHandler, HttpRequest } from '@angular/common/http'; import { Observable } from 'rxjs/Observable'; import 'rxjs/add/operator/do'; import {

I got an interface like this public interface IService { void InterceptedMethod(); } A class that implements that interface and also has another method public class Service : IService { public virtual void InterceptedMethod() { Console.WriteLine("InterceptedMethod"); } public virtual void SomeMethod() { Console.WriteLine("SomeMethod"); } } And an Interceptor public class MyInterceptor : IInterceptor { public void Intercept(IInvocation invocation) { Console.WriteLine("Intercepting"); invocation.Proceed(); } } I want to intercept only the methods on Service that exists on IService (i.e I want to

I know that this has been discussed lot of times. I just can't understand how this work or where my mistake is. I think giving you a reduced example is the best way to show you what I'm trying to do and what assumptions I'm taking... I have a Product class with a name. The name is a String property that is lazy. My DAO: public abstract class HibernateProductDAO extends HibernateDaoSupport implements ProductDAO { public List getAll() { return this.getHibernateTemplate().find("from " + this.getDomainClass().getSimpleName()); } } My Service Interface: public interface ProductService { //This
