mybatis传递多个参数的三种方式
记录一下,老是记不全。
一、
Dao层方法:
Public User selectUser(String name,String area);
对应的Mapper.xml :
<select id="selectUser" resultMap="BaseResultMap"> select * from user_user_t where user_name = #{0} and user_area=#{1} </select>
二、
Dao层方法:
Public User selectUser(Map paramMap);
对应的Mapper.xml :
<select id=" selectUser" resultMap="BaseResultMap"> select * from user_user_t where user_name = #{userName,jdbcType=VARCHAR} and user_area=#{userArea,jdbcType=VARCHAR} </select>
对应的Service层:
Private User xxxSelectUser(){ Map paramMap=new hashMap(); paramMap.put(“userName”,”对应具体的参数值”); paramMap.put(“userArea”,”对应具体的参数值”); User user=xxx. selectUser(paramMap);}
三、
Dao层方法:
Public User selectUser(@param(“userName”)Stringname,@param(“userArea”)String area);
对应的Mapper.xml :
<select id=" selectUser" resultMap="BaseResultMap"> select * from user_user_t where user_name = #{userName,jdbcType=VARCHAR} and user_area=#{userArea,jdbcType=VARCHAR} </select>
很简单的啦! =_=
