eureka添加security 后客户端启动报错：Cannot execute request on any known server

配置安全密码前可以连接成功 配置密码后无法连接

#注册中心地址用户密码地址
eureka.client.service-url.defaultZone= http://admin:[email protected]:8080/eureka/

客户端启动后日志打印

com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server
    at com.netflix.discovery.shared.transport.decorator.RetryableEurekaHttpClient.execute(RetryableEurekaHttpClient.java:111) ~[eureka-client-1.7.0.jar:1.7.0]

原因：2.1版本的security默认加上了 csrf 拦截，需要在注册中心重写 WebSecurityConfigurerAdapter中得方法禁用csrf拦截

带代码如下：

package com.sumu.eureka;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
 /**
  * 注册中心
  * @author wang
  */
@SpringBootApplication //spring-boot 启动注解
@EnableEurekaServer // spring-cloud 注册中心服务注解
public class RegisterMain{
     public static void main(String [] args) {
         SpringApplication.run(RegisterMain.class, args);
     }
     /**
      * 2.1版本的security默认加上了 csrf 拦截, 所以需要通过重写方法, 把csrf拦截禁用
     */
     @EnableWebSecurity
     static class WebSecurityConfig extends WebSecurityConfigurerAdapter {
         @Override
         protected void configure(HttpSecurity http) throws Exception {
        	 http.csrf().disable().authorizeRequests()
             .anyRequest()
             .authenticated()
             .and()
             .httpBasic();
         }
     }
}

启动客户端成功！！
