我想用 GWT Junit 测试一个 RPC。我使用标准 GWT 示例并创建以下测试用例：

public class TestGreetingService extends GWTTestCase {
/**
 * Must refer to a valid module that sources this class.
 */
public String getModuleName() {
    return "com.TestGreeting";
}   

/**
 * This test will send a request to the server using the greetServer method
 * in GreetingService and verify the response.
 */
public void testGreetingService() {
    // Create the service that we will test.
    GreetingServiceAsync greetingService = GWT
            .create(GreetingService.class);
    ServiceDefTarget target = (ServiceDefTarget) greetingService;
    target.setServiceEntryPoint(GWT.getModuleBaseURL() + "TestGreeting/greet");

    // Since RPC calls are asynchronous, we will need to wait for a response
    // after this test method returns. This line tells the test runner to
    // wait
    // up to 10 seconds before timing out.
    delayTestFinish(20000);

    // Send a request to the server.
    greetingService.greetServer("GWT User", new AsyncCallback<String>() {
        public void onFailure(Throwable caught) {
            // The request resulted in an unexpected error.
            fail("Request failure: " + caught.getMessage());
        }

        public void onSuccess(String result) {
            // Verify that the response is correct.
            assertTrue(result.startsWith("Hello, GWT User!"));

            // Now that we have received a response, we need to tell the
            // test runner
            // that the test is complete. You must call finishTest() after
            // an
            // asynchronous test finishes successfully, or the test will
            // time out.
            finishTest();
        }
    });
}
}

不幸的是，我收到以下错误：有人可以帮助我吗？我还上传了项目：goo.gl/UnFyt

您收到 404 警告，找不到您的服务。您的 ServiceEntryPoint 定义一定有问题。

尝试为您的同步接口使用 @RemoteServiceRelativePath("greet") 注释或将您的 setServiceEntryPoint 更正为

    target.setServiceEntryPoint(GWT.getModuleBaseURL() + "greet");

另请查看 DevGuide，那里的说明帮助我很好地习惯了 GWT RPC 服务： https ://developers.google.com/web-toolkit/doc/2.4/DevGuideServerCommunication#DevGuideImplementingServices
