Consider defining a bean of type 'com.kxg.swagger.mapper.UserMapper' in your configuration. 问题解决

一、错误信息

二、定位到UserMapper

package com.kxg.swagger.mapper;

import com.kxg.swagger.entity.Role;
import com.kxg.swagger.entity.User;

import org.mapstruct.Mapper;

import java.util.List;
@Mapper
public interface UserMapper {
    User loadUserByUsername(String username);
    List<Role> getUserRolesByUid(Integer id);
}

发现@Mapper导入的 org.mapstruct.Mapper 有问题 应该是

import org.apache.ibatis.annotations.Mapper;
加入后出现

再次查找原因后发现 是 mybatis 依赖信息不全所致

<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
</dependency>

缺少version所致

加入后

<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>1.3.2</version>
</dependency>

 

错误解决完毕，成功运行
