spring cloud eureka 服务端开启密码认证后，客户端无法接入问题

Eureka服务端开启密码的认证比较简单

在pom文件中加入：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>

　　配置如下：

server:
  port: 5000
spring: 
  application:
    name: EurekaServer
  security:
    user:
      name: admin
      password: 123456

eureka:
  instance:
    hostname: localhost
  client:
    register-with-eureka: false
    fetch-registry: false
    service-url:
      defaultZone: http://${spring.security.user.name}:${spring.security.user.password}@${eureka.instance.hostname}:${server.port}/eureka/

　　网页登录Eureka的管理中心时，能够正常登录，此时说明服务端配置成功

配置客户端

eureka:
  instance:
    prefer-ip-address: true
  client:
    service-url:
      defaultZone: http://admin:123456@localhost:5000/eureka/

　　

但是启动客户端之后出现如下报错：

查资料找到解决办法如下：

服务端新建配置类，禁用CSRF，并启用httpBasic，代码如下：

import org.springframework.context.annotation.Configuration;
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;

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable().httpBasic();
        //http.httpBasic();
    }
}

重新启动，看到客户端已经可以正常注册了
