博客内容讲述了在Spring框架中遇到的Bean循环引用问题，即metaTableColumnsServiceImpl和metaTableServiceImpl互相注入导致的Error creating bean异常。解决方法是在一方使用@Lazy注解以避免初始化时的循环依赖。这提醒开发者在配置Bean时要注意类型匹配的适度，考虑使用getBeanNamesForType方法并关闭eager init选项。

1.报错内容：
Error creating bean with name ‘metaTableColumnsServiceImpl’: Bean with name ‘metaTableColumnsServiceImpl’ has been injected into other beans [metaTableServiceImpl] in its raw version as part of a circular reference, but has eventually been wrapped. This means that said other beans do not use the final version of the bean. This is often the result of over-eager type matching - consider using ‘getBeanNamesForType’ with the ‘allowEagerInit’ flag turned off, for example.

2原因： metaTableColumnsServiceImpl类中注入了 metaTableServiceImpl，而在 metaTableServiceImpl类中也注入了 metaTableColumnsServiceImpl，从而引起该异常。（循环引用）

3、解决： metaTableColumnsServiceImpl类注入 metaTableServiceImpl时，增加注解 @Lazy ，反之同理。

4、@Lazy 注解路径为： org.springframework.context.annotation.Lazy 。
