MyBatis傳入多個參數

MyBatis傳入多個參數

三種方式：

1. 按照參數順序傳

   Dao層:UserMapper

   public User updateUserByPwd(String newPassword,Integer id);
   

   UseMapper.xml

   <select id="updateUserByPwd" resultMap="BaseResultMap">
       select * from user_user_t where user_pwd = #{0} and id=#{1}
   </select>
   

2. 使用Map傳參數

   Dao層:UserMapper

   public User updateUserByPwd(Map paramMap);
   

   UseMapper.xml

   <select id=" updateUserByPwd" resultMap="BaseResultMap">
      select * from user_user_t where user_pwd = #{newPassword，jdbcType=VARCHAR} and id=#{id,jdbcType=VARCHAR}
   </select>
   

3. 使用註解@param

   Dao層:UserMapper

   public User updateUserByPwd(@param("newPassword")String newPassword,@param("id")Integer id);
   

   UseMapper.xml

   <select id=" updateUserByPwd" resultMap="BaseResultMap">
      select * from user_user_t where user_pwd = #{newPassword} and id=#{id}
   </select>
