客户端注册eureka服务失败registration failed Cannot execute request on any known server

新版(2.x版本)的security默认启用了csrf检验，要在eureka服务端那边配置security的csrf检验为false
在server端，编写如下代码，再重启server和client
@EnableWebSecurity
public class WebSecurityConfigurer extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable();
super.configure(http);
}
}
