SpringCloud核心教程 | 第三篇：服務註冊與發現 Eureka篇
Spring Cloud簡介
Spring Cloud是一個基於Spring Boot實現的雲應用開發工具，它爲基於JVM的雲應用開發中涉及的配置管理、服務發現、斷路器、智能路由、微代理、控制總線、全局鎖、決策競選、分佈式會話和集羣狀態管理等操做提供了一種簡單的開發方式。html
Spring Cloud包含了多個子項目（針對分佈式系統中涉及的多個不一樣開源產品），好比：Spring Cloud Config、Spring Cloud Netflix、Spring Cloud CloudFoundry、Spring Cloud AWS、Spring Cloud Security、Spring Cloud Commons、Spring Cloud Zookeeper、Spring Cloud CLI等項目。java
微服務架構
「微服務架構」在這幾年很是的火熱，以致於關於微服務架構相關的開源產品被反覆的說起（好比： netflix、dubbo），Spring Cloud也因Spring社區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。node
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數據存儲開始垂直拆分紅多個不一樣的服務，每一個服務都能獨立部署、獨立維護、獨立擴展，服務與服務間經過諸如RESTful API的方式互相調用。mysql
對於「微服務架構」，你們在互聯網能夠搜索到不少相關的介紹和研究文章來進行學習和了解。也能夠閱讀始祖Martin Fowler的《Microservices》（中文版翻譯點擊查看），本文不作更多的介紹和描述。web
服務治理
在簡單介紹了Spring Cloud和微服務架構以後，下面迴歸本文的主旨內容，如何使用Spring Cloud來實現服務治理。redis
因爲Spring Cloud爲服務治理作了一層抽象接口，因此在Spring Cloud應用中能夠支持多種不一樣的服務治理框架，好比：Netflix Eureka、Consul、Zookeeper。在Spring Cloud服務治理抽象層的做用下，咱們能夠無縫地切換服務治理實現，而且不影響任何其餘的服務註冊、服務發現、服務調用等邏輯。spring
因此，下面咱們經過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的服務註冊與調用。sql
Spring Cloud Eureka
首先，咱們來嘗試使用Spring Cloud Eureka來實現服務治理。數據庫
Spring Cloud Eureka是Spring Cloud Netflix項目下的服務治理模塊。而Spring Cloud Netflix項目是Spring Cloud的子項目之一，主要內容是對Netflix公司一系列開源產品的包裝，它爲Spring Boot應用提供了自配置的Netflix OSS整合。經過一些簡單的註解，開發者就能夠快速的在應用中配置一下經常使用模塊並構建龐大的分佈式系統。它主要提供的模塊包括：服務發現（Eureka），斷路器（Hystrix），智能路由（Zuul），客戶端負載均衡（Ribbon）等。apache
下面，就來具體看看如何使用Spring Cloud Eureka實現服務治理，這裏使用eureka-server爲服務註冊中心工程、eureka-provider服務提供者工程、eureka-consumer服務消費者工程。

構建工程
首先構建父工程，引入父工程依賴：
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

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目錄下添加application.yml文件並加入如下配置：
#工程名稱
spring:
application:
name: eureka-server
#選擇哪個環境的配置
#這裏能夠在每一個環境配置redis，數據庫（mysql），消息（kafka）等相關的組件的配置
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:
#配置與此實例相關聯的主機名，是其餘實例能夠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和端口
instanceId: ${spring.cloud.client.ipAddress}:${server.port}
client:
#配置不將本身註冊到eureka註冊中心
register-with-eureka: false
#配置此客戶端不獲取eureka服務器註冊表上的註冊信息
fetch-registry: false
serviceUrl:
#配置默認節點有信息，這裏是獲取本機的ip和端口來實現，若是不配置，默認會找8761端口，這裏配置的是1001端口，所以會報錯
defaultZone: http://${spring.cloud.client.ipAddress}:${server.port}/eureka/
#文檔塊區分爲三個---
---
server:
port: 1001
spring:
profiles: dev
#日誌
logging:
config: classpath:log/logback.xml
path: log/eureka-server
#文檔塊區分爲三個---
---
server:
port: 1002
spring:
profiles: test
#日誌
logging:
config: classpath:log/logback.xml
path: usr/eureka-server/log/eureka-server
#文檔塊區分爲三個---
---
server:
port: 1003
spring:
profiles: prod
#日誌
logging:
config: classpath:log/logback.xml
path: usr/eureka-server/log/eureka-server
這裏日誌的配置不在詳細說明，不知道怎麼配置能夠參考這篇文章：
SpringBoot進階教程 | 第二篇：日誌組件logback實現日誌分級打印
其次：建立核心啓動類：
@EnableEurekaServer//加上此註解表示將此工程啓動後爲註冊中心
@SpringBootApplication
public class EurekaServerApplication {
public static void main(String[] args) {
new SpringApplicationBuilder(EurekaServerApplication.class).web(true).run(args);
}
}
最後：啓動項目，看到以下日誌打印信息：
. ____ _ __ _ _
/\\ / ___'_ __ _ _(_)_ __ __ _ \ \ \ \
( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \
\\/ ___)| |_)| | | | | || (_| | ) ) ) )
' |____| .__|_| |_|_| |_\__, | / / / /

這裏這看到尚未服務暴露出來，是由於還沒建立服務提供者工程。
服務提供者工程配置
這裏服務提供者是使用以前SpringBoot進階教程 | 第三篇：整合Druid鏈接池以及Druid監控改造而來，這裏同樣的部分就再也不重複說明，下面將說明新增的部分。
首先：修改application.yml配置爲以下：
#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爲依據
name: eureka-provider
#激活哪個環境的配置文件
profiles:
active: dev
#鏈接池配置
datasource:
driver-class-name: com.mysql.jdbc.Driver
# 使用druid數據源
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
# 配置一個鏈接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
# 打開PSCache，而且指定每一個鏈接上PSCache的大小
poolPreparedStatements: true
maxOpenPreparedStatements: 100
# 配置監控統計攔截的filters，去掉後監控界面sql沒法統計，'wall'用於防火牆
filters: stat,wall,log4j
# 經過connectProperties屬性來打開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，這裏使用的是本地註冊中心
eureka:
client:
serviceUrl:
defaultZone: http://localhost:1001/eureka/
#配置Swagger相關信息
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}爲該服務的端口號
#mybatis
mybatis:
# 實體類掃描
type-aliases-package: cn.zhangbox.springboot.entity
# 配置映射文件位置
mapper-locations: classpath:mapper/*.xml
# 開啓駝峯匹配
mapUnderscoreToCamelCase: true
---
#開發環境配置
server:
#端口
port: 8080
spring:
profiles: dev
# 數據源配置
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
server:
#端口
port: 80
spring:
profiles: test
# 數據源配置
datasource:
url: jdbc:mysql://127.0.0.1:3306/eureka-provider?useUnicode=true&characterEncoding=utf8&useSSL=false&tinyInt1isBit=true
username: root
password: 123456
#日誌
logging:
config: classpath:log/logback.xml
path: /home/log/eureka-provider
---
#生產環境配置
server:
#端口
port: 8080
spring:
profiles: prod
# 數據源配置
datasource:
url: jdbc:mysql://127.0.0.1:3306/eureka-provider?useUnicode=true&characterEncoding=utf8&useSSL=false&tinyInt1isBit=true
username: root
password: 123456
#日誌
logging:
config: classpath:log/logback.xml
path: /home/log/eureka-provider
其次：在config目錄下增長SwaggerConfig類加入如下代碼：
@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"))//過濾的接口，有這掃描纔會看到接口信息
.paths(PathSelectors.any())
.build();
return docket;
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder().title("eureka服務端提供者接口平臺").description("服務相關數據接口")
.termsOfServiceUrl("http://www.zhang.box.cn/").contact("技術開發部")
.license("Licence Version 1.0").licenseUrl("#").version("1.0").build();
}
}
這裏若是不會使用swagger的整合能夠參考這篇文章：
SpringBoot非官方教程 | 第十一篇：SpringBoot集成swagger2，構建優雅的Restful API
接着：建立核心啓動類：
@EnableDiscoveryClient //使用該註解將註冊服務到eureka
@SpringBootApplication
@MapperScan("cn.zhangbox.eureka.provider.dao")//配置mybatis接口包掃描
public class EurekaProviderApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(EurekaProviderApplication.class, args);
}
}
最後：啓動項目，看到以下日誌打印信息：

服務消費者工程配置
這裏構建的工程名爲eureka-consumer,上文已經構建了工程可是沒有建立目錄，這裏只須要在java目錄下建立config、controller，service，包便可，這裏服務的消費是經過feign來進行服務調用的，後面會有專門以篇文章來說feign。
首先：在eureka-consumer工程下resource目錄下添加application.yml文件並加入如下配置：
#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爲依據
application:
name: eureka-consumer
#激活哪個環境的配置文件

其次：在config目錄下增長SwaggerConfig類加入如下代碼：
@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"))//過濾的接口，有這掃描纔會看到接口信息
.paths(PathSelectors.any())
.build();
return docket;
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder().title("eureka服務端消費者接口平臺").description("服務相關數據接口")
.termsOfServiceUrl("http://www.zhang.box.cn/").contact("技術開發部")
.license("Licence Version 1.0").licenseUrl("#").version("1.0").build();
}
}
接着：在service包下建立StudentConsumerService類並加入如下代碼：
@FeignClient(value = "eureka-provider")
public interface StudentConsumerService {
/**
* 查詢全部的學生信息
*
* @param sname
* @param age
* @return
*/
@RequestMapping(value = "/student/list",method = RequestMethod.GET)
String getStudentList(@RequestParam(value = "sname") String sname, @RequestParam(value = "age") Integer age);
}
而後：在controller包下建立StudentConteroller並加入以下代碼：
@Controller
@RequestMapping("/student")
@Api(value = "eureka-consumer", description = "學生查詢接口")
public class StudentConteroller {
private static final Logger LOGGER = LoggerFactory.getLogger(StudentConteroller.class);
@Autowired
StudentConsumerService studentService;
/**
* 查詢全部的學生信息
*
* @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;
}
}
接着：建立核心啓動類：
@EnableFeignClients//開啓Feign調用接口
@EnableDiscoveryClient//開啓客戶端服務，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：啓動項目，看到以下日誌打印信息：

返回數據以下：

"ren_msg": "查詢成功",
"studentList": [{
"age": "17",
"birth": "2010-07-22",

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