spring 中的 常见注解 @param

简介

param 是作为 mapper.xml 中的映射来做的, 一般和参数写的一样即可.

mapper
Public User selectUser(@param(“userName”) String name,@param(“userpassword”) String password);

xml对应的映射

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