spring boot创建bean失败.Error creating bean with name ‘demo‘: Lookup method resolution failed_springboot jar lookup method resolution failed-优快云博客

此博客探讨了在Spring Boot应用中创建名为'demo'的bean时遇到的错误，焦点在于LookupMethodResolution失败，特别提到在Eclipse运行正常但在命令行报错。作者分析可能原因包括注解配置错误和类依赖问题，并提供了解决路径，如检查引入的系统路径资源是否打包到jar中。

spring boot创建bean失败.

Error creating bean with name 'demo': Lookup method resolution failed

引起这个问题的原因:

1. 可能是没有写对@RestController,@Service之类;

2. 也有可能是对应的类引用了一些类,是用<systemPath>引入的,在spring boot打包时,没有包含进去.然后创建bean的时候就报错.

我碰到的诡异之处在于，

在eclipse运行不报错。在dos运行就报错了。

将<systemPath>引入的包打进jar, 可参考：
