这个异常的重点是在下面图示所在
 在这里插入图片描述
 一般是application.yml文件中的书写格式不正确,找到需要修改的地方进行修改即可

引起错误的原因，在负载均衡调用时 BlockingLoadBalancerClient 会有一个 block 的操作
	@Override
	public <T> ServiceInstance choose(String serviceId, Request<T> request) {
        // 略...
        // block
		Response<ServiceInstance> loadBalancerResponse = Mono.from

				
改了springboot版本号一定要mvn idea:idea -U
java.lang.IllegalStateException: ConfigFileApplicationListener [org.springframework.boot.context.config.ConfigFileApplicationListener] is deprecated and can only be used as an EnvironmentPostProcessor
我真是裂开了，我一直以为是依赖

此监听器对配置的处理主要在ApplicationEnvironmentPreparedEvent事件阶段
onApplicationEnvironmentPreparedEvent
对在ApplicationEnviron...

请问怎么解决？？
