Jersey 2 filter uses Container Request Context in Client Request Filter

喜夏-厌秋 提交于 2020-05-10 02:58:55
问题 I have a Jersey 2 Web Service that upon receiving a request, makes another request to another web service in order to form the response for the original request. So, when client "A" makes a request to my web service "B", "B" makes a request to "C" as part of forming the response to "A". A->B->C I want to implement a filter for a Jersey 2 web service that essentially does this: Client "A" will send a request that has a header like "My-Header:first" When my web service "B" then makes a client

Java自定义注解的定义与使用

跟踪代码的依赖性,实现代替配置文件的功能。比较常见的是Spring等框架中的基于注解配置。 登陆、权限拦截、日志处理,以及各种Java框架,如Spring,Hibernate,JUnit 。提到注解就不能不说反射,Java自定义注解是通过运行时靠反射获取注解。实际开发中,例如我们要获取某个方法的调用日志,可以通过AOP(动态代理机制)给方法添加切面,通过反射来获取方法包含的注解,如果包含日志注解,就进行日志记录。 注解是Java 1.5引入的,目前已被广泛应用于各种Java框架,如Hibernate, Jersey ,Spring。注解相当于是一种嵌入在程序中的元数据,可以使用注解解析工具或编译器对其进行解析,也可以指定注解在编译期或运行期有效。 在注解诞生之前,程序的元数据存在的形式仅限于java注释或javadoc,但注解可以提供更多功能,它不仅包含元数据,还能作用于运行期,注解解析器能够使用注解决定处理流程。举个例子,在 Jersey webservice 中,我们在一个方法上添加了PATH注解和URI字符串,在运行期,jersey会对其进行解析,并决定作用于指定URI模式的方法。 在Java中创建自定义注解 创建自定义注解与编写接口很相似,除了它的接口关键字前有个@符号。我们可以在注解中定义方法,先来看个例子,之后我们会继续讨论它的特性。 package com

What is the most portable (or standard) way of returning a list as a response in jax-rs?

﹥>﹥吖頭↗ 提交于 2020-04-30 12:25:30
问题 Well, anybody can say this question is already asked and answered. Never mind I also found them. JAX-RS: How to automatically serialize a collection when returning a Response object? Using Java-generics template type in RESTful Response object via GenericEntity<List<T>> I'm not confused with the way of responding with an List<T> but just not convinced about the portability. Let's say I have a nicely annotated entity looks like this. @XmlRootElement public class Stock { @XmlAttribute private

Jersey Equivalent to HttpUrlConnection

放肆的年华 提交于 2020-04-30 10:19:13
问题 So I am trying to add a cookie to a connection. In HTTPUrlConnection, I do the following: HttpURLConnection con; String cookieString = null; con = ((HttpURLConnection) new URL(appUrl).openConnection()); String cookieString = formatCookies("session", userCredential); con.setRequestProperty("Cookie", cookieString); ... I want to do the same in Jersey. So far I have the following: WebTarget wt = client.target(appUrl).path(path); wt.queryParam(..., ...) .request(...) .cookie("session",
