博客提到遇到报错但不影响启动的问题，网上类似问题是Spring Boot集成Elasticsearch报错Health check failed，解决办法是在配置文件中增加配置关闭安全检查，最终问题得到解决。

上面就是错误日志，报错但是不影响启动，非常烦恼。

网上搜到类似的问题是 springBoot集成Elasticsearch 报错 Health check failed

解决方法也是类似，在配置文件中增加一个配置把安全检查关调！

management:
  health:
    ldap:
      enabled: false

或者说是

management.health.ldap.enabled=false

先记到这问题是解决了

LDAP health check failed 难道没有人遇到这样的问题吗？！！
