问题 I have a project using Jersey v2.25.1. I was using Jersey's inbuilt HK2 injection to perform dependency injection, and everything worked fine.

When I ran my project, I got the following exception: java.lang.IllegalStateException: InjectionManagerFactory not found After some googling, I found that I needed to add the jersey-hk2 dependency. Doing so made me get the following exception: org.glassfish.hk2.api.UnsatisfiedDependencyException

问题 I Have made a jax rs jersey web service. I have to load data from database when server restarts.

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 简介 Feign是一款java的Restful客户端组件，Feign使得 Java HTTP 客户端编写更方便。Feign 灵感来源于Retrofit, JAXRS-2.0和WebSocket。Feign 最初是为了降低统一绑定Denominator 到 HTTP API 的复杂度，不区分是否支持 ReSTfulness。为什么选择Feign而不是其他你可以使用 Jersey 和 CXF 这些来写一个 Rest 或 SOAP 服务的java客服端。你也可以直接使用 Apache HttpClient 来实现。但是 Feign 的目的是尽量的减少资源和代码来实现和 HTTP API 的连接。通过自定义的编码解码器以及错误处理，你可以编写任何基于文本的 HTTP API。 Feign工作机制 Feign 通过注解注入一个模板化请求进行工作。只需在发送之前关闭它，参数就可以被直接的运用到模板中。然而这也限制了 Feign，只支持文本形式的API，它在响应请求等方面极大的简化了系统。同时，它也是十分容易进行单元测试的。基本用法基本的使用如下所示，一个对于canonical Retrofit sample的适配。 interface GitHub { @RequestLine("GET /repos/{owner

问题 I'm new to Jersey (2.22.2), so bear with me please. I am creating a REST service that interfaces with an LDAP server for storing, removing, and retrieving user data. The service acts as a security intermediary by performing encryption/decryption. There is quite a bit of initialization that must take place before the REST services can be utilized, and I would like to only perform this initialization once (when the application is deployed on the server). So this service would be run as a
