Mybatis错误：Parameter ‘XXX‘ not found. Available parameters are [1, 0, param1, param2]

原因：传递的参数超过一个

记

解决办法：

（1）直接把值改成数字

<select id="LoginUser" parameterType="String" resultMap="userMap">
  SELECT * FROM user where emplnumb = #{0} and password=#{1}
</select>

（2）在变量上加注解@Param

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

　　

public List<user> getUserInformation(@Param("user") User user);
