AcceptedByMethodRestEasy的 创建一个类，这两个PreProcessInterceptor和AcceptedByMethod。在accept-方法，您可以检查是否有带注释的@QueryParam("name")。如果有一个注释，返回与真实accept-方法。 在preProcess-方法，你可以从查询request.getUri().getQueryParameters().getFirst("name")。 编辑： 下面是一个例子：public class InterceptorTest {
@Path("/")
public static class MyService {
@GET
public String listByName(@QueryParam("name") String name){
return "not-intercepted-" + name;
}
}
public static class MyInterceptor implements PreProcessInterceptor, AcceptedByMethod {
@Override
public boolean accept(Class declaring, Method method) {
for (Annotation[] annotations : method.getParameterAnnotations()) {
for (Annotation annotation : annotations) {
if(annotation.annotationType() == QueryParam.class){
QueryParam queryParam = (QueryParam) annotation;
return queryParam.value().equals("name");
}
}
}
return false;
}
@Override
public ServerResponse preProcess(HttpRequest request, ResourceMethod method)
throws Failure, WebApplicationException {
String responseText = "intercepted-" + request.getUri().getQueryParameters().getFirst("name");
return new ServerResponse(responseText, 200, new Headers<Object>());
}
}
@Test
public void test() throws Exception {
Dispatcher dispatcher = MockDispatcherFactory.createDispatcher();
dispatcher.getProviderFactory().getServerPreProcessInterceptorRegistry().register(new MyInterceptor());
dispatcher.getRegistry().addSingletonResource(new MyService());
MockHttpRequest request = MockHttpRequest.get("/?name=xxx");
MockHttpResponse response = new MockHttpResponse();
dispatcher.invoke(request, response);
assertEquals("intercepted-xxx", response.getContentAsString());
}
}

2. 如果返回return new ServerResponse(responseText, 200, new Headers<Object>());你将失去的终点。你需要返回null如果你还想被传递到终点。
