Spring 事务下 openSessionInViewFilter flushMode 的问题
这是 applicationContext.xml

这是 UserServiceImpl 代码

import dao.InfoContextlistDAO;
import dao.InfoFeedbackDAO;
import dao.InfoMsgsDAO;

public class UserServiceImpl implements IUserService {

private InfoContextlistDAO infoContextlistDAO;
private InfoFeedbackDAO infoFeedbackDAO;
private InfoMsgsDAO infoMsgsDAO;

public void setInfoContextlistDAO(InfoContextlistDAO infoContextlistDAO){
this.infoContextlistDAO = infoContextlistDAO;
}

public InfoContextlistDAO getInfoContextlistDAO(){
return this.infoContextlistDAO;
}

public void setInfoFeedbackDAO(InfoFeedbackDAO infoFeedbackDAO){
this.infoFeedbackDAO = infoFeedbackDAO;
}

public InfoFeedbackDAO getInfoFeedbackDAO(){
return this.infoFeedbackDAO;
}

public void setInfoMsgsDAO(InfoMsgsDAO infoMsgsDAO){
this.infoMsgsDAO = infoMsgsDAO;
}

public InfoMsgsDAO getInfoMsgsDAO(){
return this.infoMsgsDAO;
}
}


这是 UserServiceImpl 的接口 IUserService

package service;

import dao.InfoContextlistDAO;
import dao.InfoFeedbackDAO;
import dao.InfoMsgsDAO;

public interface IUserService {

public void setInfoContextlistDAO(InfoContextlistDAO infoContextlistDAO);

public InfoContextlistDAO getInfoContextlistDAO();

public void setInfoFeedbackDAO(InfoFeedbackDAO infoFeedbackDAO);

public InfoFeedbackDAO getInfoFeedbackDAO();

public void setInfoMsgsDAO(InfoMsgsDAO infoMsgsDAO);

public InfoMsgsDAO getInfoMsgsDAO();

}



按道理事务也配置成功了，可是为什么还是报这个错误：
