我有一个 Maven 基础 GWT 应用程序。

当我通过 Maven 编译、构建并将其部署到 JBoss AS 7.1.1 时，我的 GWT-RPC-Service 会出现 ClassNotFoundException。在我包括我部署之前，我可以显示 GWT-Widgets，所以 GWT-Jars 应该在那里......

我的 Maven 依赖项如下所示：

<dependency>
  <groupId>com.google.gwt</groupId>
  <artifactId>gwt-dev</artifactId>
  <version>2.5.0</version>
  <scope>compile</scope>
</dependency>
<dependency>
  <groupId>com.google.gwt</groupId>
  <artifactId>gwt-user</artifactId>
  <version>2.5.0</version>
  <scope>compile</scope>
</dependency>
<dependency>
  <groupId>com.google.gwt</groupId>
  <artifactId>gwt-servlet</artifactId>
  <version>2.5.0</version>
  <scope>compile</scope>
</dependency>

我的 EAR 看起来像这样：

-myEar.ear
|  |
|  |- core.jar
|
|--|- gwt-ui.war
|  |
|  |-- gwt-ui
|  |   |--  gwt
|  |   |--  sc
|  |   |--  wgt-ui.nocache.js
|  |
|  |-- META-INF
|  |   | (is Empty)
|  |
|  |-- WEB-INF
|  |   |-- classes
|  |   |     |
|  |   |     |- mygwtProj.client
|  |   |     |   |- services
|  |   |     |   |   | - MyService.class
|  |   |     |   |   | - MyServiceAsync.class
|  |   |     |   |- dto
|  |   |     |   |   | - DTO.class
|  |   |     |
|  |   |     |- mygwtProj.server
|  |   |     |   |- MyServiceImpl.class
|  |   |-- deploy
|  |   |-- lib
|  |   |     | (all gwt-jars-files)
|  |   |-- beans.xml
|  |   |-- web.xml

我的服务：

import java.util.List;
import com.google.gwt.user.client.rpc.RemoteService;
import com.google.gwt.user.client.rpc.RemoteServiceRelativePath;
import mygwtProj.client.dto.DTO;

@RemoteServiceRelativePath("myService")
public interface ShopService extends RemoteService{
    List<DTO> getAircrafts();
}

我的服务异步

import java.util.List;
import com.google.gwt.user.client.rpc.AsyncCallback;
import mygwtProj.client.dto.DTO;

@RemoteServiceRelativePath("myService")
public interface ShopService extends RemoteService{
    void getAircrafts(AsyncCallback<List<DTO>> callback); 
}

我的服务实现

import java.util.ArrayList;
import java.util.List;
import com.google.gwt.user.server.rpc.RemoteServiceServlet;
import mygwtProj.client.dto.DTO;
import mygwtProj.client.services.MyService;

public class MyServiceImpl extends RemoteServiceServlet implements MyService {
    private static final long serialVersionUID = 1L;

@Override
public List<DTO> getAircrafts() {

    List<DTO> list = new ArrayList<DTO>(1);
    list.add(new ShopItemDTO(1, "man", "typ", 1.0));
    return list;
}
}

有人知道出了什么问题吗？

感谢您的输入。我现在找出问题所在。

是一个愚蠢的错误。在 maven 配置中，我设置 client-Package 中的所有类都不应该包含在包装中，因为它们被编译为 JS。所以这包括我的服务接口......我将它移动到一个新的包共享并将其包含在 gwt.xml 中。

还将 gwt-user 和 gwt-dev 更改为提供的 maven 范围，并将 gwt-servlet 更改为运行时。

使用此配置它可以工作:-)
