GWT错误：必须运行RequestFactory ValidationTool

时间：2013-05-04 11:40:03

标签： java gwt dao requestfactory objectify

每次启动我的应用程序时，即使未执行listEmptyBoxes（），也会出现“RequestFactory Validation Tool必须运行...”错误。我已经在注释处理上有文件requestfactory-apt-2.5.0-rc1.jar。

有什么想法吗？在我的代码下面。感谢。

MyProject.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;
    }
}

答案 1 :(得分：2)

从GWT 2.4开始，必须验证RequestFactory接口。那么，你有没有仔细看过instructions？在那里你可以找到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的类文件，它在WEB-INF/classes目录中与"YourRequestFactoryName".class一起生成。因此，检查它的存在，您确定验证工具已运行（或将其删除以确保它必须运行）。

instruction现在看起来很旧了。使用最新的RequestFactory ValidationTool 3。*：

运行maven-compiler-plugin 
<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>
