记录一个问题

springboot启动的时候遇到一个报错：

The bean 'myShiroRealm', defined in class path resource [com/demo/config/ShiroConfig.class], could not be registered. A bean with that name has already been defined in file [F:\demo\target\classes\com\demo\shiro\MyShiroRealm.class] and overriding is disabled.

 

查了查解决的办法，也有人遇到过类似的问题，他们是怎么做的呢？

1   在配置文件中添加：

spring.main.allow-bean-definition-overriding=true

springboot 解决 The bean 'userRepository', defined in null, could not be registered. A bean with that name has already been defined in file XXX and overriding is disabled. - panchanggui - 博客园 https://www.cnblogs.com/panchanggui/p/10406680.html

2  还有一个人建议把springboot pom改一下，sringboot 2.1.x 并不支持这种操作，改回到2.0.x，项目正常启动。

我用了这位仁兄的方法，我原来用的是2.1.2，改成了2.0.2.

嗯，还有好多错，继续改错去。。
