CXF REST呼び出しの呼び出し時にスローされる例外

Question

私はCXF &のSpringバックエンドとExtJSフロントエンドを持つRESTサービスを持っています。

サービスのGETメソッドは完全に機能します。私は新しいバックエンドで新しいDAOと実装でPOSTサービスを実装しようとしました。

パラメータが正常にサービスに渡されていることを確認しましたが、バックエンドメソッドを呼び出すと、トレースできない異常な例外が返されます。

は私がデバッグモードで実行し、それがメソッドの呼び出しに失敗したことを知っていました - サービスは、次のように実装されます。

@Override 
    @POST 
    @Produces("application/json") 
    @Path("/updatestatus") 
    public boolean updateReportStatus(@FormParam("reportDate") String reportDt, @FormParam("status") String status) { 
     System.err.println("report date = "+reportDt); 
     System.err.println("status = "+status); 
     System.err.println("In service to update"); 
     gridUpdateDao.updateStatus(); 
.......

だけの提案、あなたは

@Consumes(MediaType.APPLICATION_FORM_URLENCODED) 

を追加しようとしています
