异常提示：

When allowCredentials is true, allowedOrigins cannot contain the special value "*" since that cannot be set on the "Access-Control-Allow-Origin" response header. To allow credentials to a set of origins, list them explicitly or consider using "allowedOriginPatterns" instead.

#解决办法：
跨域配置报错，将.allowedOrigins替换成.allowedOriginPatterns即可。

异常提示：

Failed to start bean 'documentationPluginsBootstrapper'; nested exception is java.lang.NullPointerException
