利用hibernate 的save() 插入数据0 actual row count: 0 expected: 1

我用的springside+hibernate3+struts.2.0开发的
已经调了很长时间 找不到解决方法；谢谢：

我的action 调用save后就报上面的错
public class SendDocmentInfoAction extends BaseAction{
public String save(){
try{

        tProMd5 = new TProMd5();
        tProMd5.setFormcode(formcode);
        tProMd5.setProcessId(proId);
        tProMd5.setMdproId(unid);
        );
//能得到formcode  +proId unid                                                         
   System.out.println("md5save" +formcode +proId +unid);       

                                                  
        sendDocmentMd5Manager.save(tProMd5);

        }catch(Exception e){
        e.printStackTrace();
        return INPUT;
        }
        saveMessage("数据" + (id == null ? "新增" : "保存") + "成功!");       
        return SUCCESS;
}
}
