问题描述

我正在尝试使用 RESTEasy 作为 JAX-RS 2.0 客户端实现.问题是我遇到了运行时异常:

I'm trying to use RESTEasy as JAX-RS 2.0 client implementation. The problem is that I got runtime exception:

06-28 13:29:06.410: E/AndroidRuntime(5745): Caused by: java.lang.RuntimeException: java.lang.ClassNotFoundException: org.glassfish.jersey.client.JerseyClientBuilder
06-28 13:29:06.410: E/AndroidRuntime(5745):     at javax.ws.rs.client.ClientBuilder.newBuilder(ClientBuilder.java:103)

所以 newBuilder() 方法正在搜索 JerseyClientBuilder 如果我理解正确的话.如何让系统改用 RESTEasy?

So the newBuilder() method is searching for JerseyClientBuilder if I understand it correct. How can I tell the system to use RESTEasy instead?

推荐答案

嗯,JAX-RS 依赖于 Service Provider 约定.在 newBuilder 方法的第一行,您可以阅读:

Well, JAX-RS relies on the Service Provider convention. On the first lines of the newBuilder method you can read:

 Object delegate = FactoryFinder.find(JAXRS_DEFAULT_CLIENT_BUILDER_PROPERTY,
   JAXRS_DEFAULT_CLIENT_BUILDER); 

其中 JAXRS_DEFAULT_CLIENT_BUILDER_PROPERTY"javax.ws.rs.client.ClientBuilder"

反过来,FactoryFinder看起来

  • 先将类名改成META-INF/services/javax.ws.rs.client.ClientBuilder
  • 然后在 javax.ws.rs.client.ClientBuilder 属性中放入 ${java.home}/lib/jaxrs.properties
  • 最后进入System属性javax.ws.rs.client.ClientBuilder.
  • first for the class name into META-INF/services/javax.ws.rs.client.ClientBuilder
  • then in the property javax.ws.rs.client.ClientBuilder into ${java.home}/lib/jaxrs.properties
  • finally into the System property javax.ws.rs.client.ClientBuilder.

所以,要使用 RESTEasy,你应该创建一个文件

So, to use RESTEasy, you should create a file

META-INF/services/javax.ws.rs.client.ClientBuilder

附上文字:

org.jboss.resteasy.client.jaxrs.ResteasyClientBuilder

这是RESTEasy的类名ClientBuilder

which is the class name of the RESTEasy ClientBuilder
