nacos启动报错 Error creating bean with name ‘authFilterRegistration‘ defined in class path resource

今天启动nacos的时候突然报错，nacos启动界面报错信息如下：

1.  
   Error creating bean with name 'authFilterRegistration' defined in class path resource
2.  
   [com/alibaba/nacos/core/auth/AuthConfig.class]:
3.  
   Bean instantiation via factory method failed;
4.  
   nested exception is org.springframework.beans.BeanInstantiationException:
5.  
   Failed to instantiate [org.springframework.boot.web.servlet.FilterRegistrationBean]:
6.  
   Factory method 'authFilterRegistration' threw exception;
7.  
   nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException:
8.  
   Error creating bean with name 'authFilter':

24.  
    Invocation of init method failed; nested exception is java.lang.RuntimeException:
25.  
    java.lang.RuntimeException: [db-load-error]load jdbc.properties error

 idea后台打印错误信息：

[NACOS SocketTimeoutException httpGet] currentServerAddr:http://localhost:8848， err : connect timed out

原因分析：项目可能没有正确加载nacos相关文件

解决办法：删除现有nacos文件夹，重新解压或下载nacos压缩包，启动startup.cmd，问题解决

若还报错，可能是startup.cmd文件中set MODE = ""不恰当

1.  
   set BASE_DIR="�SE_DIR:~0,-5%"
2.  
    
3.  
   set CUSTOM_SEARCH_LOCATIONS=file:�SE_DIR%/conf/
4.  
    
5.  
   set MODE="cluster"
6.  
   set FUNCTION_MODE="all"
7.  
   set SERVER=nacos-server
8.  
   set MODE_INDEX=-1
9.  
   set FUNCTION_MODE_INDEX=-1
10.  
    set SERVER_INDEX=-1
11.  
    set EMBEDDED_STORAGE_INDEX=-1
12.  
    set EMBEDDED_STORAGE=""

解决办法：将set MODE="cluster"改为set MODE="standalone"即可。
