The following candidates were found but could not be injected:
	- Bean method 'reactorNettyWebSocketClient' in 'GatewayAutoConfiguration.NettyConfiguration' not loaded because @ConditionalOnClass did not find required class 'reactor.ipc.netty.http.client.HttpClient'
 
 
Action:

Disconnected from the target VM, address: '127.0.0.1:52208', transport: 'socket'

今天玩gateway报错,然后看了百度很多方案.还是不行.最后尝试改了两个地方:

1.版本: 网上很多教程说了boot要在2.0.0版本,因为我的boot2.1.5和cloud版本Finchley.RELEASE一直不行.  最后我换了boot版本为2.0.0

2.排包: pom中需要排包

附上我的pom,然后启动完全ok了~
