Description:

The bean 'customUserService', defined in class path resource [com/oldwu/config/WebSecurityConfig.class], could not be registered. A bean with that name has already been defined in URL [jar:file:/www/wwwroot/dg.tingkai.tk/auto_plan-https.jar!/BOOT-INF/classes!/com/oldwu/security/CustomUserService.class] and overriding is disabled.

Action:

Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true

[zhichao12]

重复引入bean, 配置文件中的spring.main.allow-bean-definition-overriding=true 没生效, 在resources新建一个配置文件, 将application-example.yml内容全部复制过去, 就行

同样遇到这个问题，我直接把yml改写成properties
