springboot踩坑日记——Field xxx.xxx.xxx required a bean of type 'xxx.xxx.xxx' that could not be found

使用feign时报创建的feign接口找不到

错误原因:

CustomerAreaApi找不到, 添加@FeignClient注解的接口没有扫描到

推测错误原因:

使用feign要在启动类上加@EnableFeignClients注解,可能是缺少此注解

错误原因:

虽然我加了@EnableFeignClients ,由于springboot默认扫码启动类所在目录的子目录,而我的feign不在此目录下,所以要在@EnableFeignClients注解上添加basePackages属性

解决:

在@EnableFeignClients添加扫码路径

注意:修改@ComponentScan 没用
