每次我启动我的应用程序时，即使未执行 listEmptyBoxes()，我也会收到“RequestFactory Validation Tool must be run...”错误。我已经有requestfactory-apt-2.5.0-rc1.jar关于注释处理的文件。

有任何想法吗？在我的代码下面。谢谢。

我的项目.java

private void listEmptyBoxes() {
  BoxRequest boxRequest = requestFactory.boxRequest();
  boxRequest.listAllEmpty().fire(new Receiver<List<BoxProxy>>() {
    public void onSuccess(List<BoxProxy> response) { // List all phantom boxes
      Window.alert("Successful");
    }
  });
}

BoxRequest.java

@Service(value=BoxDao.class, locator=DaoServiceLocator.class)
public interface BoxRequest extends RequestContext {
    Request<List<BoxProxy>> listAllEmpty();
}

BoxDao.java

public class BoxDao extends ObjectifyDao<Box>{
    public List<Box> listAllEmpty() {
        Objectify ofy = ObjectifyService.begin();
        Query<Box> q=ofy.query(Box.class).filter("title", null).filter("description", null);
        List<Box> results = q.list();
        return results;
    }
}

错误

  1. 右键单击项目
  2. 单击 Java 编译器
  3. 启用项目特定设置
  4. 选择注解处理
  5. 启用项目特定设置
  6. 选择工厂路径
  7. 添加 Jar -> 添加 requestfactory-apt.jar 文件 -> OK -> OK
  8. 完毕

从 GWT 2.4 开始，必须验证 RequestFactory 接口。那么，您是否认真按照说明进行操作？在那里您可以找到 Eclipse/IntelliJ 以及 Maven/Ant 命令行步骤（也可以在评论中查看）。

验证工具的输出是一个名为"YourRequestFactoryName"DeobfuscatorBuilder.class并在WEB-INF/classes目录中生成的类文件，旁边是"YourRequestFactoryName".class. 所以检查它的存在，你会确定验证工具已经运行（或删除它以确保它必须运行）。

该指令现在似乎很老了。RequestFactory ValidationTool使用最新的maven-compiler-plugin3.*运行：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.1</version>
    <configuration>
        <forceJavacCompilerUse>true</forceJavacCompilerUse>
    </configuration>
    <dependencies>
        <dependency>
            <groupId>com.google.web.bindery</groupId>
            <artifactId>requestfactory-apt</artifactId>
            <version>2.6.1</version>
        </dependency>
    </dependencies>
</plugin>
