java 数据批量添加、批量更新 操作数据库

采用mybatis的批量插入方法

示例xml

 
        insert into test_user(u_name,create_date)
        values
        
            (#{item.userName},SYSDATE())
        
    

示例代码

 List userList = new ArrayList();

        for (int i = 1; i <= num; i++) {
            User user = new User();
            user.setUserName("a" + i);
            user.setCreateDate(new Date());
            userList.add(user);
        }
        userDao.batchInsertList(userList);
