项目中在使用lombok的@RequiredArgsConstructor配合final做自动注入时，出现了循环依赖的问题。
idea 控制台输出：

***************************
APPLICATION FAILED TO START
***************************

Description:

The dependencies of some of the beans in the application context form a cycle:

   dutyShiftController defined in file [D:\workspace\idea\itff\itff-service\target\classes\com\bdyl\msc\itff\service\controller\fireFightingManage\duty\DutyShiftController.class]
┌─────┐
|  dutyShiftService defined in file [D:\workspace\idea\itff\itff-service\target\classes\com\bdyl\msc\itff\service\service\fireFightingManage\duty\DutyShiftService.class]
↑     ↓
|  dutyTaskService defined in file [D:\workspace\idea\itff\itff-service\target\classes\com\bdyl\msc\itff\service\service\fireFightingManage\duty\DutyTaskService.class]
└─────┘


Action:

Despite circular references being allowed, the dependency cycle between beans could not be broken. Update your application to remove the dependency cycle.

Disconnected from the target VM, address: '127.0.0.1:63542', transport: 'socket'

Process finished with exit code 0

解决办法：
1、改用@Autowird注解注入
2、@RequiredArgsConstructor(onConstructor_ = {@Lazy})
原因：
@RequiredArgsConstructor是使用构造器注入方式，这种方式会有循环依赖的问题。
