谷歌云端硬盘API的Java用户类

我试图用这个代码来获得谷歌驱动器的授权用户名：谷歌云端硬盘API的Java用户类

public class list extends HttpServlet{ 

    private DbxClient client; 
    String token; 

    public void doGet(HttpServletRequest req, HttpServletResponse res)throws ServletException, IOException{ 

     try{ 
      DbxRequestConfig requestConfig = new 
      DbxRequestConfig("JavaDropBoxTutorial/1.0",Locale.getDefault().toString()); 

      HttpSession session = req.getSession(); 
      token = session.getAttribute("access_token").toString(); 

      client = new DbxClient(requestConfig, token); 

        session.setAttribute("dropuser",client.getAccountInfo().displayName); 

      User u = new User(); 
      System.out.print(u.getDisplayName()); 

      res.sendRedirect("listdetails.jsp"); 
     } 
     catch(Exception e){ 
     } 
    } 
}

但我得到这个错误： -

HTTP Status 500 - Servlet execution threw an exception

随着例外

javax.servlet.ServletException: Servlet execution threw an exception org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52)

根源

java.lang.NoClassDefFoundError: com/google/common/base/Preconditions

m试图获取谷歌驱动器授权用户的名字 –

请考虑将您的代码示例缩小为[最小，完整且可验证的示例]（http://stackoverflow.com/help/m cve）并改进格式以使其更具可读性。 –

你code和Error不清除的问题，但你可以在下面查找（按评论）：

下面的代码用它来获得谷歌授权的用户的用户名驱动器：

try { 
     About about = service.about().get().execute(); 
     System.out.println("Current user name: " + about.getName()); 

    } catch (IOException e) { 
     System.out.println("An error occurred: " + e); 
    }
