Spring Cloud簡介
Spring Cloud是一個基於Spring Boot實現的雲應用開發工具，它為基於JVM的雲應用開發中涉及的配置管理、服務發現、斷路器、智慧路由、微代理、控制匯流排、全域性鎖、決策競選、分散式會話和叢集狀態管理等操作提供了一種簡單的開發方式。
Spring Cloud包含了多個子專案（針對分散式系統中涉及的多個不同開源產品），比如：Spring Cloud Config、Spring Cloud Netflix、Spring Cloud CloudFoundry、Spring Cloud AWS、Spring Cloud Security、Spring Cloud Commons、Spring Cloud Zookeeper、Spring Cloud CLI等專案。
微服務架構
“微服務架構”在這幾年非常的火熱，以至於關於微服務架構相關的開源產品被反覆的提及（比如： netflix、dubbo），Spring Cloud也因Spring社群的強大知名度和影響力也被廣大架構師與開發者備受關注。
那麼什麼是“微服務架構”呢？簡單的說，微服務架構就是將一個完整的應用從資料儲存開始垂直拆分成多個不同的服務，每個服務都能獨立部署、獨立維護、獨立擴充套件，服務與服務間通過諸如RESTful API的方式互相呼叫。
對於“微服務架構”，大家在網際網路可以搜尋到很多相關的介紹和研究文章來進行學習和了解。也可以閱讀始祖Martin Fowler的《Microservices》（中文版翻譯點選檢視），本文不做更多的介紹和描述。
服務治理
在簡單介紹了Spring Cloud和微服務架構之後，下面迴歸本文的主旨內容，如何使用Spring Cloud來實現服務治理。
由於Spring Cloud為服務治理做了一層抽象介面，所以在Spring Cloud應用中可以支援多種不同的服務治理框架，比如：Netflix Eureka、Consul、Zookeeper。在Spring Cloud服務治理抽象層的作用下，我們可以無縫地切換服務治理實現，並且不影響任何其他的服務註冊、服務發現、服務呼叫等邏輯。
所以，下面我們通過Eureka這種種服務治理的實現來體會Spring Cloud這一層抽象所帶來的好處。
下一篇介紹基於Consul的服務註冊與呼叫。
Spring Cloud Eureka
首先，我們來嘗試使用Spring Cloud Eureka來實現服務治理。
Spring Cloud Eureka是Spring Cloud Netflix專案下的服務治理模組。而Spring Cloud Netflix專案是Spring Cloud的子專案之一，主要內容是對Netflix公司一系列開源產品的包裝，它為Spring Boot應用提供了自配置的Netflix OSS整合。通過一些簡單的註解，開發者就可以快速的在應用中配置一下常用模組並構建龐大的分散式系統。它主要提供的模組包括：服務發現（Eureka），斷路器（Hystrix），智慧路由（Zuul），客戶端負載均衡（Ribbon）等。
下面，就來具體看看如何使用Spring Cloud Eureka實現服務治理，這裡使用eureka-server為服務註冊中心工程、eureka-provider服務提供者工程、eureka-consumer服務消費者工程。
準備工作
環境：

工程構建完成。
服務註冊中心工程配置
首先：在eureka-server工程下resource目錄下新增application.yml檔案並加入以下配置：
#工程名稱
spring:
application:
name: eureka-server
#選擇哪一個環境的配置
#這裡可以在每個環境配置redis，資料庫（mysql），訊息（kafka）等相關的元件的配置
profiles:
active: dev
#配置eureka註冊中心
eureka:
#server:
#配置關閉自我保護模式
#enableSelfPreservation: false
#配置Eureka Server清理無效節點的時間間隔
#eviction-interval-timer-in-ms: 4000
instance:
#配置與此例項相關聯的主機名，是其他例項可以用來進行請求的準確名稱
hostname: eureka-server
#顯示服務ip地址
preferIpAddress: true
#獲取服務的ip和埠
instanceId: ${spring.cloud.client.ipAddress}:${server.port}
client:
#配置不將自己註冊到eureka註冊中心
register-with-eureka: false
#配置此客戶端不獲取eureka伺服器登錄檔上的註冊資訊
fetch-registry: false
serviceUrl:
#配置預設節點有資訊，這裡是獲取本機的ip和埠來實現，如果不配置，預設會找8761埠，這裡配置的是1001埠，因此會報錯
defaultZone: http://${spring.cloud.client.ipAddress}:${server.port}/eureka/
#文件塊區分為三個---
---
server:
port: 1001
spring:
profiles: dev
#日誌
logging:
config: classpath:log/logback.xml
path: log/eureka-server
#文件塊區分為三個---
---
server:
port: 1002
spring:
profiles: test
#日誌
logging:
config: classpath:log/logback.xml
path: usr/eureka-server/log/eureka-server
#文件塊區分為三個---
---
server:
port: 1003
spring:
profiles: prod
#日誌
logging:
config: classpath:log/logback.xml
path: usr/eureka-server/log/eureka-server
這裡日誌的配置不在詳細說明，不知道怎麼配置可以參考這篇文章：
SpringBoot進階教程 | 第二篇：日誌元件logback實現日誌分級列印
其次：建立核心啟動類：
@EnableEurekaServer//加上此註解表示將此工程啟動後為註冊中心
@SpringBootApplication
public class EurekaServerApplication {
public static void main(String[] args) {
new SpringApplicationBuilder(EurekaServerApplication.class).web(true).run(args);
}
}
最後：啟動專案，看到如下日誌列印資訊：

這裡這看到還沒有服務暴露出來，是因為還沒建立服務提供者工程。
服務提供者工程配置
這裡服務提供者是使用之前SpringBoot進階教程 | 第三篇：整合Druid連線池以及Druid監控改造而來，這裡一樣的部分就不再重複說明，下面將說明新增的部分。
首先：修改application.yml配置為如下：
#公共配置
server:
port: 80
tomcat:
uri-encoding: UTF-8
spring:
application:
#服務名稱，更關鍵，使用feign進行服務消費將以此為依據
name: eureka-provider
#啟用哪一個環境的配置檔案
profiles:
active: dev
#連線池配置
datasource:
driver-class-name: com.mysql.jdbc.Driver
# 使用druid資料來源
type: com.alibaba.druid.pool.DruidDataSource
druid:
# 配置測試查詢語句
validationQuery: SELECT 1 FROM DUAL
# 初始化大小，最小，最大
initialSize: 10
minIdle: 10
maxActive: 200
# 配置一個連線在池中最小生存的時間，單位是毫秒
minEvictableIdleTimeMillis: 180000
testOnBorrow: false
testWhileIdle: true
removeAbandoned: true
removeAbandonedTimeout: 1800
logAbandoned: true
# 開啟PSCache，並且指定每個連線上PSCache的大小
poolPreparedStatements: true
maxOpenPreparedStatements: 100
# 配置監控統計攔截的filters，去掉後監控介面sql無法統計，'wall'用於防火牆
filters: stat,wall,log4j
# 通過connectProperties屬性來開啟mergeSql功能；慢SQL記錄
connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
#配置eureka獲取服務地址，這裡使用的是本地註冊中心
eureka:
client:
serviceUrl:
defaultZone: http://localhost:1001/eureka/
#配置Swagger相關資訊
instance:
prefer-ip-address: true
instanceId: ${spring.cloud.client.ipAddress}:${server.port}
status-page-url: http://${spring.cloud.client.ipAddress}:${server.port}/swagger-ui.html # ${server.port}為該服務的埠號
#mybatis
mybatis:
# 實體類掃描
type-aliases-package: cn.zhangbox.springboot.entity
# 配置對映檔案位置
mapper-locations: classpath:mapper/*.xml
# 開啟駝峰匹配
mapUnderscoreToCamelCase: true
---
#開發環境配置
server:
#埠
port: 8080
spring:
profiles: dev
# 資料來源配置
datasource:
url: jdbc:mysql://101.132.66.175:3306/student?useUnicode=true&characterEncoding=utf8&useSSL=false&tinyInt1isBit=true
username: root
password: 123456
#日誌
logging:
config: classpath:log/logback.xml
path: log/eureka-provider

#測試環境配置

spring:

# 資料來源配置
datasource:

#日誌

#生產環境配置

# 資料來源配置
datasource:

#日誌
logging:
config: classpath:log/logback.xml
path: /home/log/eureka-provider
其次：在config目錄下增加SwaggerConfig類加入以下程式碼：
@Configuration
@EnableSwagger2
public class SwaggerConfig {
@Bean
public Docket userApi() {
Docket docket = new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.basePackage("cn.zhangbox.eureka.provider.controller"))//過濾的介面，有這掃描才會看到介面資訊
.paths(PathSelectors.any())
.build();
return docket;
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder().title("eureka服務端提供者介面平臺").description("服務相關資料介面")
.termsOfServiceUrl("http://www.zhang.box.cn/").contact("技術開發部")
.license("Licence Version 1.0").licenseUrl("#").version("1.0").build();
}
}
這裡如果不會使用swagger的整合可以參考這篇文章：
SpringBoot非官方教程 | 第十一篇：SpringBoot整合swagger2，構建優雅的Restful API
接著：建立核心啟動類：
@EnableDiscoveryClient //使用該註解將註冊服務到eureka
@SpringBootApplication
@MapperScan("cn.zhangbox.eureka.provider.dao")//配置mybatis介面包掃描
public class EurekaProviderApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(EurekaProviderApplication.class, args);
}
}
最後：啟動專案，看到如下日誌列印資訊：

點選Status下的ip後可以跳轉看到swagger的頁面並可是測試服務提供者的介面，如下：

服務消費者工程配置
這裡構建的工程名為eureka-consumer,上文已經構建了工程但是沒有建立目錄，這裡只需要在java目錄下建立config、controller，service，包即可，這裡服務的消費是通過feign來進行服務呼叫的，後面會有專門以篇文章來講feign。
首先：在eureka-consumer工程下resource目錄下新增application.yml檔案並加入以下配置：
#公共配置
server:
port: 80
tomcat:
uri-encoding: UTF-8
spring:
#服務名稱，更關鍵，使用feign進行服務消費將以此為依據
application:
name: eureka-consumer
#啟用哪一個環境的配置檔案

其次：在config目錄下增加SwaggerConfig類加入以下程式碼：
@Configuration
@EnableSwagger2
public class SwaggerConfig {
@Bean
public Docket userApi() {
Docket docket = new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.basePackage("cn.zhangbox.eureka.consumer.controller"))//過濾的介面，有這掃描才會看到介面資訊
.paths(PathSelectors.any())
.build();
return docket;
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder().title("eureka服務端消費者介面平臺").description("服務相關資料介面")
.termsOfServiceUrl("http://www.zhang.box.cn/").contact("技術開發部")
.license("Licence Version 1.0").licenseUrl("#").version("1.0").build();
}
}
接著：在service包下建立StudentConsumerService類並加入以下程式碼：
@FeignClient(value = "eureka-provider")
public interface StudentConsumerService {
/**
* 查詢所有的學生資訊
*
* @param sname
* @param age
* @return
*/
@RequestMapping(value = "/student/list",method = RequestMethod.GET)
String getStudentList(@RequestParam(value = "sname") String sname, @RequestParam(value = "age") Integer age);
}
然後：在controller包下建立StudentConteroller並加入如下程式碼：
@Controller
@RequestMapping("/student")
@Api(value = "eureka-consumer", description = "學生查詢介面")
public class StudentConteroller {
private static final Logger LOGGER = LoggerFactory.getLogger(StudentConteroller.class);
@Autowired
StudentConsumerService studentService;
/**
* 查詢所有的學生資訊
*
* @param sname
* @param age
* @param modelMap
* @return
*/
@ResponseBody
@GetMapping("/consumer/list")
public String list(
@ApiParam(value = "學生姓名") @RequestParam(required = false) String sname,
@ApiParam(value = "年齡") @RequestParam(required = false) Integer age,
ModelMap modelMap) {
String json = null;
try {
json = studentService.getStudentList(sname, age);
} catch (Exception e) {
e.printStackTrace();
modelMap.put("ren_code", "0");
modelMap.put("ren_msg", "查詢失敗===>" + e);
LOGGER.error("查詢失敗===>" + e);
json = JSON.toJSONString(modelMap);
}
return json;
}
}
接著：建立核心啟動類：
@EnableFeignClients//開啟Feign呼叫介面
@EnableDiscoveryClient//開啟客戶端服務，沒有這個註解會報Feign找不到對應服務的錯誤
@SpringBootApplication
public class EurekaConsumerApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(EurekaConsumerApplication.class, args);
}
}
最後：啟動專案，看到如下日誌列印資訊：

至此eureka-consumer服務提供者建立完成，瀏覽器輸入地址：http://127.0.0.1:8081/swagger-ui.html
同樣也可以點選eureka控制檯中Application為EUREKA-CONSUMER後Status下的ip後可以跳轉看到swagger的頁面並可是測試服務消費者的介面,可以看到如下頁面，並點選try it out按鈕，返回了正確的學生資訊資料

返回資料如下：

}
以上就是spring cloud基於eurka實現分散式服務註冊與消費的整合流程，是不是很簡單，你也來小試牛刀一把吧。
