spring Cloud Eureka增加security后注册失败解决方案

本人在使用SpringCloud搭建项目的时候，需要在Eureka上增加白名单，进行注册权限控制.参照官网方式总是注册失败，如下错误

折腾了好久终于找到了解决办法，如下：
本人使用的springboot版本是2.1.0.RELEASE springCloud版本是Greenwich.M3
原因是springboot引入spring-boot-starter-security做安全校验后，自动开启CSRF安全认证，任何一次服务请求默认都需要CSRF 的token（自行补脑Spring的CSRF验证），而Eureka-client不会生成该token，故启动时会报如上错误。
网络上也有多种解决方案，本人试了几个要么仍是注册失败，要么是用户名密码失效，最终参照ryanjbaxter大神给出的方案解决(点击链接)。

方案一：
Eureka server配置：

server.port=8090
spring.security.user.roles=SUPERUSER
spring.security.user.name=test
spring.security.user.password=testAdmin
eureka.client.register-with-eureka=true
eureka.client.fetch-registry=false
eureka.instance.hostname=localhost
eureka.client.serviceUrl.defaultZone=http://test:testAdmin@localhost:8090/eureka

Eureka server ApplicationClass配置

package com.eureka.demo;

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;

@EnableEurekaServer
@SpringBootApplication
public class DemoApplication {

	public static void main(String[] args) {
		SpringApplication.run(DemoApplication.class, args);
	}
	@EnableWebSecurity
	static class WebSecurityConfig extends WebSecurityConfigurerAdapter {
		@Override
		protected void configure(HttpSecurity http) throws Exception {
			http.csrf().ignoringAntMatchers("/eureka/**");
			super.configure(http);
		}
	}
}

客户端配置：

spring.security.user.name=test
spring.security.user.password=testAdmin
spring.application.name=pricing-APIService
eureka.client.serviceUrl.defaultZone=http://test:testAdmin@localhost:8090/eureka

启动后，查看eureka控制台（http://localhost:8090/）输入密码，登录

方案二(该方案未亲自验证)
服务端自己重写WebSecurityConfigurerAdapter，客户端配置不变。如下

@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter{

    @Override
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
    	auth.inMemoryAuthentication()
        .passwordEncoder(NoOpPasswordEncoder.getInstance())
        .withUser("test").password("testAdmin")
        .authorities("SUPERUSER");
    }
    
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
        	.csrf()
        		.disable()
	        .authorizeRequests()
	          .anyRequest().authenticated()
	          .and()
	          .httpBasic();
    }
}
