Spring cloud 教程
1. 服务的注册与发现（Eureka）
1.1 spring cloud简介
spring cloud 为开发人员提供了快速构建分布式系统的一些工具，包括配置管理、服务发现、断路器、路由、微代理、事件总线、全局锁、决策竞选、分布式会话等等。它运行环境简单，可以在开发人员的电脑上跑。另外说明spring cloud是基于springboot的，所以需要开发中对springboot有一定的了解，如果不了解的话可以看这篇文章：2小时学会springboot。另外对于“微服务架构” 不了解的话，可以通过搜索引擎搜索“微服务架构”了解下。
1.2创建服务注册中心
在这里，我们需要用的的组件上Spring Cloud Netflix的Eureka,eureka是一个服务注册和发现模块。
1.2.1pom依赖配置如下：

1.2.2配置文件配置如下：
server.port=8888
eureka.instance.hostname=localhost
#是否将eureka自身作为应用注册到eureka注册中心,Eureka只作为Server端，所以不用向自身注册
eureka.client.registerWithEureka=false
eureka.client.fetchRegistry=false
#配置安全验证，用户名及密码,pom文件增加权限配置时需要用户名密码
security.basic.enabled=true
security.user.name=test
security.user.password=123456
#eureka的地址，多个eureka服务地址，可以用，号隔开
eureka.client.serviceUrl.defaultZone=http://localhost:8888/eureka/
1.2.3启动类
@EnableEurekaServer //开启eureka服务
@SpringBootApplication //springBoot注解,spring在springBoot基础之上来构建项目
public classEurekaServiceApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaServiceApplication.class, args);
}
}
1.2.4浏览器访问如下：
如果配置了权限和用户名密码，则需要输入管理用户名和密码

2.2Eureka客户端配置文件配置
(1)applications.properties
#客户端端口
server.port=8081
#应用名字，该名字将注册到eureka注册中心
spring.application.name=config-client
#获取的服务端配置文件名称前缀
spring.cloud.config.name=server-config
#获取的服务端文件后缀例子：service-config-beta.properties
spring.cloud.config.profile=beta
#mybatis 整合 xml配置方式,ps：注解方式sql不需要下面2个配置
mybatis.config-locations=classpath:mybatis/mybatis-config.xml
mybatis.mapper-locations=classpath:mybatis/mapper/*.xml
(2) bootstrap.properties
#启动需要用bootstrap文件配置spring.cloud.config.uri
#服务端url
spring.cloud.config.uri=http://localhost:8080
#注册中心
#服务注册的Eureka Server地址,EurekaServer application.properties 中配置
eureka.client.serviceUrl.defaultZone=http://test:123456@localhost:8888/eureka
#实例名称显示IP配置如下：
eureka.instance.preferIpAddress=true
#自定义应用实例id
#eureka.instance.instanceId=${spring.application.name}:${spring.application.instance_id:${server.port}}
#健康检查
eureka.client.healthcheck.enabled=true
2.3 客户端启动类配置
@EnableDiscoveryClient //通过该注解，实现服务发现，注册
@SpringBootApplication
@MapperScan("com.test.configclient.mapper")//配置扫描mapper包，或者在mapper类上配置@Mapper亦可
public classConfigClientApplication {
public static void main(String[] args) {
newSpringApplicationBuilder(ConfigClientApplication.class).web(true).run(args);
}
}
2.4Eureka客户端调用
/**
* 如果你的应用使用@EnableEurekaClient注解，那么只能使用eureka来发现服务实例。
* @author Administrator
*
*/
@RequestMapping("/eurekaClient")
@RestController
public classEurekaTestController {
//Eureka客户端
@Autowired
privateEurekaClient eurekaClient;
//服务发现客户端
@Autowired
privateDiscoveryClient discoveryClient;
/**
* 获得Eureka instance的信息，传入Application NAME
*
* */
@RequestMapping("/eurekaInstance")
publicString serviceUrl(){
InstanceInfo instance = this.eurekaClient.getNextServerFromEureka("CONFIG-CLIENT",false);
return instance.getHomePageUrl();
}
/**
* 本地服务实例信息
* */
@RequestMapping("/instanceInfo")
publicServiceInstance showInfo(){
ServiceInstance localServiceInstance = this.discoveryClient.getLocalServiceInstance();
return localServiceInstance;
}
}
打开浏览器访问如下：
3.服务消费者Feign
3.1 Feign简介
Feign是一个声明式的伪Http客户端，它使得写Http客户端变得更简单。使用Feign，只需要创建一个接口并注解。它具有可插拔的注解特性，可使用Feign 注解和JAX-RS注解。Feign支持可插拔的编码器和解码器。Feign默认集成了Ribbon，并和Eureka结合，默认实现了负载均衡的效果。
简而言之：
- Feign 采用的是基于接口的注解
- Feign 整合了ribbon
3.2新建feign maven工程，添加pom依赖

}
4. spring cloud配置中心配置
4.1简介
在分布式系统中，由于服务数量巨多，为了方便服务配置文件统一管理，实时更新，所以需要分布式配置中心组件。在Spring Cloud中，有分布式配置中心组件spring cloud config ，它支持配置服务放在配置服务的内存中（即本地），也支持放在远程Git仓库中。在spring cloud config组件中，分两个角色，一是config server，二是config client。
