Mybatis傳遞多個參數

方法一：

//DAO層的函數方法
Public User selectUser(String name,String area);      

對應的Mapper.xml 

<select id="selectUser" resultMap="BaseResultMap">
    select  *  from user_user_t   where user_name = #{0} and user_area=#{1}
</select>      

其中，#{0}代表接收的是dao層中的第一個參數，#{1}代表dao層中第二參數，更多參數一緻往後加即可。

方法二：采用Map傳多參數.

//Dao層的函數方法
Public User selectUser(Map paramMap);      

對應的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>      

Service層調用

Private User xxxSelectUser(){
Map paramMap=new hashMap();
paramMap.put(“userName”,”對應具體的參數值”);
paramMap.put(“userArea”,”對應具體的參數值”);
User user=xxx. selectUser(paramMap);}      

Public User selectUser(@param(“userName”)Stringname,@param(“userArea”)String area);      

<select id=" selectUser" resultMap="BaseResultMap">
   select  *  from user_user_t   where user_name = #{userName，jdbcType=VARCHAR} and user_area=#{userArea,jdbcType=VARCHAR}
</select>
