使用CXF中的javax.ws.rs.client.ClientBuilder创建客户端，是否可以使用本地传输的任何路由? [英] Using javax.ws.rs.client.ClientBuilder in CXF to create Client, any route to be able to use local transport?

问题描述

我正在使用从CXF发行版使用标准"javax.ws.rs.client.ClientBuilder"类的代码库来配置和创建"javax.ws.rs.client.Client".

I work on a codebase that uses the standard "javax.ws.rs.client.ClientBuilder" class, from the CXF distribution, to configure and create a "javax.ws.rs.client.Client".

这很好用.

我现在正在尝试编写测试，这些测试使用内联类定义的控制器使用JAXRSServerFactoryBean来管理假服务器.在测试和客户端配置中，我都可以将host:port设置为localhost:something，并且效果很好，足以让我测试MessageBodyReaders和Http异常处理.

I'm now trying to write tests that use JAXRSServerFactoryBean to manage a fake server using a controller defined by an inline class. I can set my host:port to localhost:something, both in the test and in the client configuration, and this works well enough to allow me to test our MessageBodyReaders and Http exception handling.

但是，我认为这不是可扩展的"，因为每个假服务器都必须在专用"端口上运行(至少在运行测试时).我可以尝试使用不常见的端口，并让不同的测试使用不同的端口，或者使用随机数，但这都有些冒险.我真的不希望CI构建失败，因为并行运行的测试最终使用了相同的端口.

However, I think this won't be "scalable", as each fake server will have to run on a "dedicated" port (while running the test, at least). I can try to use uncommon ports, and have different tests use different ports, or use random numbers, but that's all somewhat risky. I don't really want CI builds to fail because tests running in parallel ended up using the same port.

我了解到CXF(不是JAX-RS)使用本地传输"的能力(

I read about the ability in CXF (not JAX-RS) to use "local transport" (https://cwiki.apache.org/confluence/display/CXF20DOC/JAXRS+Testing). It appears that might resolve my problem. I need to verify this, but it's possible that two tests running in parallel both using local transport will not conflict.

但是，我什至无法使它工作，因为我们的客户端代码使用的是标准" JAX-RS客户端类，而不是CXF客户端类.它们似乎不同且不兼容.

However, I can't even get this to work yet, because our client code is using the "standard" JAX-RS client class, not the CXF one. They appear to be different and incompatible.

在创建客户端时，我尝试执行此操作(只是看它是否可以工作):

At the point where I create the client, I tried to do this (just to see if it can work):

WebClient.getConfig(client).getRequestContext().put(LocalConduit.DIRECT_DISPATCH, Boolean.TRUE);

不幸的是，此操作失败，并在"org.apache.cxf.jaxrs.client.WebClient.getConfig(Object)"中显示不是有效的客户端"，因为它必须是"org.apache.cxf.jaxrs.client.Client"的实例，而不是javax.ws.rs.client.Client.

Unfortunately, this fails with "Not a valid Client" in "org.apache.cxf.jaxrs.client.WebClient.getConfig(Object)" because it needs to be an instance of "org.apache.cxf.jaxrs.client.Client", not javax.ws.rs.client.Client.

这里是否有任何简单(甚至可能)的路径?

Is there any easy (or even possible) path forward here?

推荐答案

您可以使用

You can use ClientRequestFilters to unit test JAX-RS clients. Basically register a custom ClientRequestFilter to your Client object (or ClientBuilder) that mocks your response using the abortWith(Response) method on the ClientRequestContext object that is passed in to the filter method.

类似的事情应该起作用:

Something like this should work:

public MyMockRequestFilter implements ClientRequestFilter {
  @Override
  public void filter(ClientRequestContext requestContext) {
    MyEntity entity = // get the entity you want to mock as returned from the server
    requestContext.abortWith(Request.ok(entity).build());
  }
}
...
ClientBuilder builder = ClientBuilder.newBuilder().register(MyMockRequestFilter .class)
