SpringBoot 2.3.7版本，Eureka server配置认证后，client无法连接

问题描述：

eureka server 项目pom中添加配置

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

yml中添加如下配置：

spring:
  security:
    user:
      name: user                # 配置登录的账号是user
      password: password123     # 配置登录的密码是password123

eureka客户端配置：

eureka:
  client:
    serviceUrl:
      defaultZone: http://user:password123@peer1:8761/eureka/,http://user:password123@peer2:8762/eureka    # 指定注册中心的地址
  instance:
    preferIpAddress: true

客户端尝试连接时报如下错误：

问题解决：    

eureka server项目中添加如下配置类并重启server，客户端就可以正常注册了。

 

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;


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