Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.boot.web.servlet.FilterRegistrationBean]: Factory method 'authFilterRegistration' threw exception; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'authFilter': Unsatisfied dependency expressed through field 'authManager'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'nacosAuthManager': Unsatisfied dependency expressed through field 'authenticationManager'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'nacosAuthConfig': Unsatisfied dependency expressed through field 'userDetailsService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'nacosUserDetailsServiceImpl': Unsatisfied dependency expressed through field 'userPersistService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'externalUserPersistServiceImpl': Unsatisfied dependency expressed through field 'persistService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'externalStoragePersistServiceImpl': Invocation of init method failed; nested exception is java.lang.RuntimeException: java.lang.RuntimeException: [db-load-error]load jdbc.properties error

解决办法：

• 启动时使用 如下命令

startup.cmd -m standalone

• 如果还是启动报错就尝试删除
• data 文件夹下的内容 重启Nacos

与SpringBoot整合报错

问题描述：

nacosProperties (field private java.util.Optional com.alibaba.cloud.nacos.NacosDiscoveryProperties.nacosAutoServiceRegistrationOptional)

Relying upon circular references is discouraged and they are prohibited by default. Update your application to remove the dependency cycle between beans. As a last resort, it may be possible to break the cycle automatically by setting spring.main

报错版本：

• nacos 注册中心版本为2.0.3 
• nacos-discovery 为 2.2.2.RElEASE 

修改方法：

• 升级nacos-discovery 版本到 2.2.7.RELEASE

总结

以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。
