MyBatis_[tp_50]_动态sql_bind绑定 与原生sql对比

笔记要点
出错分析与总结

更推荐,原生的sql写法,bind方法不灵活!
Test中:
e.setLastName("%e%");  直接在这里写上模糊查询的语句,更加省时
配置中:
不用bind!

1.定义接口

 public List<Employee> getEmpsTestInnerParameter(Employee employee);//测试内部参数

2.定义XML映射文件

 @Test
    public void test11() throws Exception {
        SqlSession openSession = getSqlSessionFactory().openSession();
        try {
            System.out.println("++++++++++---- tp48.测试动态sql_bind");
            EmployeeMapper_DynamicSQL mapper = openSession.getMapper(EmployeeMapper_DynamicSQL.class);
            Employee e=new Employee();
            e.setLastName("e");
           // e.setLastName("%e%");  直接在这里写上模糊查询的语句,更加省时
            List<Employee> list = mapper.getEmpsTestInnerParameter(e);
            for(Employee e1:list)
                System.out.println(e1);

            openSession.commit();
        } finally {
            openSession.close();
        }
    }
