启动sringboot时出现如下错误，主要错误为：nsatisfied dependency expressed through field ‘baseMapper’; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type ‘com.bowen.dao.mapper.ArticlesMapper’ available:
意思是通过一堆连带关系，最后发现无法创建ArticlesMapper。

解决办法

  • 方法1：springapplication启动文件加入如下代码
  1. //扫描 mybatis mapper 包路径
  2. @MapperScan(basePackages = "com.bowen.dao.mapper")
  • 方法2：com.bowen.dao.mapper.ArticlesMapper加入注解@Mapper
  1. package com.bowen.dao.mapper;
  2. import com.bowen.dao.model.Articles;
  3. import com.baomidou.mybatisplus.core.mapper.BaseMapper;
  4. import org.apache.ibatis.annotations.Param;
  5. import org.apache.ibatis.annotations.Select;
  6. import org.apache.ibatis.annotations.Update;
  7. import java.util.List;
