There is no getter for property named 'id' in class 'java.lang.String'

使用mybatis传入参数，如果在mappin.xml中使用<if>标签判断该参数是否为空，通常会报以上异常，解决方法：​在接口中该方法的参数前加上@Param("参数名")注解，即可​

接口：

public interface UserMapper {

//根据名称查询用户

List<MAP> queryUserByName(@Param("name")String name);

}​

mapping.xml:​

<mapper namespace="com.mybatis.test.dao.UserMapper">
<select id="queryUserByName" parameterType="String" resultType="java.util.HashMap">
select 
t_id as id,
t_name as name,
t_password as password
from mybatis_user
where 1=1 
<if test="name != null">
and t_name=#{name}
</if>
order by t_id
</select>
</mapper>
