java后端自学错误总结
一.SpringBoot–正在总结中
1.循环嵌套异常
今天再写SpringCloud项目的时候书写测试类运行结果报错了报错的最后的信息是
The dependencies of some of the beans in the application context form a cycle:
newsConfigController (field private com.shengkong.article.service.newsConfigService com.shengkong.article.controller.v1.newsConfigController.newsConfigService)
