Eureka進行安全控制，通過用戶名密碼來注冊到注冊中心

首先導入maven依賴

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

然后在配置文件中添加

spring:
  application:
    name: eureka-server
  security:
    user:
      name: admin
      password: 123456

此時啟動注冊中心就需要輸入賬號密碼登錄了

 

修改EurekaClient配置

eureka:
  instance:
    prefer-ip-address: true
  client:
    serviceUrl:
      defaultZone: http://admin:123456@localhost:8761/eureka/

如果不配置用戶名和密碼，會報401錯誤

Request execution failure with status code 401; retrying on another server if available

配置上以后還會報錯

Request execution failure with status code 403; retrying on another server if available

這是因為Eureka 默認啟用了csrf檢驗，可以將其disable掉

在Eureka注冊中心添加如下代碼：

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 WebSecurityConfigurer extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable();
        super.configure(http);
    }
}

重啟注冊中心，就會發現服務注冊上來了

但是注冊中心日志還會報錯

Batch update failure with HTTP status code 401; discarding 1 replication tasks

這是因為在eureka注冊中心啟用了security安全機制，因此在進行配置defualtZone時也要設置下相關用戶名和密碼，配置如下：

eureka:
  instance:
    prefer-ip-address: true
  client:
    registerWithEureka: false
    fetchRegistry: false
    server:
      waitTimeInMsWhenSyncEmpty: 0
    service-url:
      defaultZone: http://${spring.security.user.name}:${spring.security.user.password}@localhost:8761/eureka/

注冊中心整體配置如下：
