记录一下

今天在写为服务项目碰到的错误，如下面所示，只知道创建Error creating bean with name ‘servletEndpointRegistrar’ defined in class path resource失败，在网上也找了一些解决方法，最多的解决答案是说缺少jdbc依赖，要么就是说数据库配置文件出错了，我也比对了下数据库没错，也没缺少jdbc依赖，这说明我的数据库和依赖都没错，我就又比对了下其他service服务，发现就是配置文件多引入了个配置文件

我的nacos文件配置是

#HTTP格式配置spring:
http:
  encoding:
    charset: UTF‐8
    force: true
    enabled: true
  messages:
    encoding: UTF‐8
#tomcat头信息(用户ip和访问协议)及访问路径配置
server:
  tomcat:
    remote_ip_header: x‐forwarded‐for
    protocol_header: x‐forwarded‐proto
  servlet:
    context‐path: /lifly
  use‐forward‐headers: true

#服务监控与管理配置，运维相关
management:
  endpoints:
    web:
      exposure:
      include: refresh,health,info,env

这个配置文件就是定义了用户ip和访问路径以及一些与服务监控与管理与运维相关的配置文件，但是service中并没有用到远程调用，我却将该配置文件引入了，我的出错原因是这个，就记录下来了。
我的bootstrap.yml配置文件如下：

我的把那个引入文件注释掉，项目就起来了。再次记录下，也希望对你们有帮助。将下面的引入文件注释掉

 ext-config:
          -
            refresh: true
            data-id: spring-boot-http.yaml # spring boot http配置
