spring-cloud配置：服务中心

我就是我 2022-03-26 05:42 197阅读 0赞

**Spring Cloud**是一系列框架的有序集合。它利用Spring Boot的开发便利性巧妙地简化了分布式系统基础设施的开发，如服务发现注册、配置中心、消息总线、负载均衡、断路器、数据监控等，都可以用Spring Boot的开发风格做到一键启动和部署。Spring Cloud并没有重复制造轮子，它只是将目前各家公司开发的比较成熟、经得起实际考验的服务框架组合起来，通过Spring Boot风格进行再封装屏蔽掉了复杂的配置和实现原理，最终给开发者留出了一套简单易懂、易部署和易维护的分布式系统开发工具包。

--------------------

下面配置spring cloud的服务中心Netflix Eureka：

首先先创建项目，选择左侧的导航栏的**Spring Initializr**，然后默认是Default选项。

对项目信息进行编辑，填写组织名和项目名。

选择Cloud Discovery，然后右侧选择Eureka Server(因为创建的是服务中心，所以选择Server)。

编辑项目名及存放路径，然后下一步就创建完项目了：

创建好的项目展示：

接下来配置文件：

往pom.xml文件添加所需jar包和配置，请大家根据版本选择(我用的是Dalston，所以parent标签里的version是1.5.x版本，spring-cloud.version是Dalston)：

            </repository>
        </repositories>
    
    </project>

然后到SpringbootEurekaApplication文件中添加注解：

@EnableEurekaServer

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTU5NTcwMA_size_16_color_FFFFFF_t_70 5][]

接下来到resoures下的application.properties(我把后缀改成yml，效果相同)配置代码：

#设置端口号
    server:
      port: 7000
    
    #配置服务中心
    eureka:
      client:
        fetch-registry: false
        register-with-eureka: false
        #访问网址路径：(配置的账号:密码@本机:端口号/eureka/)
        service-url:
          defaultZone: http://root:111111@localhost:7000/eureka/
    
    #配置安全设置(需要账号密码登录,user账号，password密码，enable true为激活)
    security:
      user:
        name: root
        password: 111111
      basic:
        enabled: true

然后点击右上角的虫子(Debug)启动，访问localhost:7000(设置端口号)，输入设置的账号密码，点击登录：

如图显示便配置成功：
