步骤：
1.新建new-other

2.选择Junit Test Case

3.注意红线圈出部分

4.选择需要测试的方法

5.Finish后出现如下

示例代码：

package com.jrgc.dao;

import java.util.List;

import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.Transaction;

import com.jrgc.entity.User;
import com.jrgc.util.SessionUtil;

public class UserDaoImp implements UserDao{

    @SuppressWarnings("unchecked")
    @Override
    public List<User> userList() {
        Session session = SessionUtil.getSession();
        /**
         * from User中的User是实体类(entity)
         */
        String hql = "from User";
        return session.createQuery(hql).list();
    }

    @Override
    public void save(User u) {
        Session session = SessionUtil.getSession();
        Transaction tran = session.beginTransaction();
        try {
            session.save(u);
            tran.commit();
        } catch (HibernateException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            tran.rollback();
        }finally{
            SessionUtil.closeSession();
        }
        
    }

}
