本文记录了一个使用Springside框架结合Hibernate3和Struts2.0进行开发时遇到的StaleStateException异常，具体表现为更新操作返回的行数与预期不符，实际为0，期望为1。文章提供了出现问题的hbm.xml配置文件及Action代码段，寻求解决此问题的方法。

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

tProMd5 = new TProMd5();
tProMd5.setFormcode(formcode);
tProMd5.setProcessId(proId);
tProMd5.setMdproId(unid);
);
[color=darkred]//能得到formcode +proId unid [/color]
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;
}
}
