hibernate报错object references an unsaved transient instance - save the transient instance before flushing: com.king3d.manage.domain.Sys2;
从URL传入参数，会报这个错误，但是JUNIT中测试就没有任何问题，不知道原因。action与service代码如下
[code="java"]
@Action(results = { @Result(type = "json") }, value = "saveSub")
public String saveSub() throws Exception {
Tools.decodeObject(sys2);
dic.saveDictionaryData(sys2);
resultStatus = "true";
return "success";
[/code]
[code="java"]
@Transactional
public void saveDictionaryData(Sys2Vo sys2vo) throws Exception {
Sys2 entry = new Sys2();
BeanUtils.copyProperties(sys2vo, entry);
if(sys2vo.getId() > 0){
this.sys2Dao.update(entry);
}else{
this.sys2Dao.save(entry);
}
sys2vo.setId(entry.getId());
}
[/code]
