标签:arch 解决 col ltm base arc mapper dao层 style
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>
其中,#{0}代表接收的是dao层中的第一个参数,#{1}代表dao层中第二参数,更多参数一致往后加即可。
此方法采用Map传多参数.
Dao层的函数方法
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>
Dao层的函数方法
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>
Mybatis传多个参数(三种解决方案) mapper.xml的sql语句修改!
