我正在尝试使用GWT进行RPC测试。我正在使用提到的here的默认StockWatcher项目,我下载了该项目,将其导入,一切正常。

然后,我在StockWatcher项目中运行junitcreator:

/Users/stephen/Work/gwt/gwt-mac-1.6.4/junitCreator -junit   /Users/stephen/Applications/eclipse/plugins/org.junit_3.8.2.v20080602-1318/junit.jar -module stockwatcher -eclipse StockWatcher com.google.gwt.sample.stockwatcher.StockWatcherTest


这将在适当的测试目录中创建StockWatcherTest.java,并为我提供了一些托管模式和Web模式启动文件。

然后,我还将junit.jar添加到该项目的类路径中。

然后,我修改StockWatcherTest.java以测试我是否能够向服务器发出异步请求。一切看起来都很好,但是当我尝试在托管模式下运行StockWatcherTest.java时,出现以下错误:


  在端口0 HTTP上启动HTTP
  
  在端口49569上侦听
  
  开发外壳servlet收到了
  请求模块中的“问候”
  'com.google.gwt.sample.stockwatcher.StockWatcher.JUnit.gwt.xml'
  [WARN]找不到资源:打招呼;
  (如果文件从
  公用路径或标签
  模块中配置错误
  com.google.gwt.sample.stockwatcher.StockWatcher.JUnit.gwt.xml
  ?)
  com.google.gwt.user.client.rpc.StatusCodeException:
  找不到资源“问候”
  模块的公共路径
  'com.google.gwt.sample.stockwatcher.StockWatcher.JUnit'


这是我的StockWatcherTest.java类

package com.google.gwt.sample.stockwatcher.client;

import com.google.gwt.core.client.GWT;
import com.google.gwt.junit.client.GWTTestCase;
import com.google.gwt.user.client.rpc.AsyncCallback;

/**
 * GWT JUnit tests must extend GWTTestCase.
 */
public class StockWatcherTest extends GWTTestCase {

  /**
   * Must refer to a valid module that sources this class.
   */
  public String getModuleName() {
    return "com.google.gwt.sample.stockwatcher.StockWatcher";
  }

  /**
   * Add as many tests as you like.
   */
  public void testSimple() {
      GreetingServiceAsync greetingService = GWT.create(GreetingService.class);
      greetingService.greetServer("Bob",
                new AsyncCallback<String>() {
                    public void onFailure(Throwable caught) {
                        // Show the RPC error message to the user
                        System.out.println(caught);
                        fail("big time failure");
                        finishTest();
                    }

                    public void onSuccess(String result) {
                        System.out.println("success, biatch");
                        assertTrue(true);
                    }
                });
      delayTestFinish(1000);
  }

}


这是com / google / gwt / sample / stockwatcher / StockWatcher.gwt.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 1.6.2//EN" "http://google-web-toolkit.googlecode.com/svn/tags/1.6.2/distro-source/core/src/gwt-module.dtd">

这是我产生的战争中的web.xml

  <!-- Servlets -->

  </servlet>

  <servlet-mapping>
    <servlet-name>greetServlet</servlet-name>
    <url-pattern>/stockwatcher/greet</url-pattern>
  </servlet-mapping>

</web-app>


那我在做什么错?任何帮助表示赞赏。谢谢。

最佳答案

1-您需要添加“ finishTest();”在“ onSuccess”方法的末尾。

2,然后解决您遇到的问题:在StockWatcher.gwt.xml中添加servlet问候的路径。

Servlet路径='/ greet'class ='com.google.gwt.sample.stockwatcher.server.GreetingServiceImpl'/
