MyBatis @ResultMap引起的错误.

Question

<mapper namespace="xyz.ivyxjc.RoleMapper">
   <resultMap id="roleMapper" type="role">
       <id column="id" property="roleName" javaType="string" jdbcType="VARCHAR"/>

       <result column="role_name" property="roleName" javaType="string" jdbcType="VARCHAR"/>
       <result column="note" property="note" typeHandler="xyz.ivyxjc.MyStringTypeHandler"/>
   </resultMap>
</mapper>

@ResultMap(value = "roleMapper")
@Select(value = "select id, role_name as roleName, note from t_role where id=#{id}")
public Role getRole(Long id);

这时会引起以下错误, 但是只有这一个名称为getRole的方法.
java.lang.IllegalArgumentException: Mapped Statements collection already contains value for xyz.ivyxjc.RoleMapper.insertRole

如何解决这个错误.

Answer 1

报错的是 insertRole ，写重复了？
