hibernate update 错误解决
update时候出现如下错误
org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session:
解决方法：
根据id得到缓存里的pojo对象，修改该对象，更新该对象
public void update(AppInfo appInfo){AppInfo ai = getAIById(appInfo.getId());ai.setAct(appInfo.getAct());ai.setApp_name(appInfo.getApp_name());ai.setApp_id(appInfo.getApp_id());ai.setInstall_ram_range(appInfo.getInstall_ram_range());ai.setPackage_name(appInfo.getPackage_name());ai.setSwitch_ram_range(appInfo.getSwitch_ram_range());Transaction ts = s.beginTransaction();s.update(ai);ts.commit();}
