mybatis-plus报错,之前使用mybatis-plus却没有遇到过的问题
Description:
Field baseMapper in com.baomidou.mybatisplus.extension.service.impl.ServiceImpl required a single bean, but 3 were found:
- permissionMapper: defined in file [D:XXX\mapper\PermissionMapper.class]
- userMapper: defined in file [D:XXX\mapper\UserMapper.class]
- userRoleMapper: defined in file [D:XXX\mapper\UserRoleMapper.class]
Action:
Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed
Disconnected from the target VM, address: '127.0.0.1:58072', transport: 'socket'
Process finished with exit code 1
它也给了两个解决办法
1.把其中一个bean加上@Primary注解,就可以作为默认使用,
2.在注入的属性添加@Qualifier指定beanName,以明确使用哪一个bean
但是经过测试我把其他bean都删掉只剩一个也是报错,所以这两个办法并不能帮助我解决问题。
最后查资料发现可以去扫描一下mp的mapper的路径就没问题了
“com.baomidou.mybatisplus.core.mapper”
如果泛型没有写上可能也会出现这个问题,注意避坑
