## Eureka服務端 服務端引入依賴: ~~~ <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId> <version>2.0.1.RELEASE</version> </dependency> </dependencies> ~~~ 啟動類加注解: ~~~ package com.like; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer; @SpringBootApplication @EnableEurekaServer //標注此為eureka服務端 public class EurekaServer { public static void main(String[] args) { SpringApplication.run(EurekaServer.class); } } ~~~ ~~~ server: port: 10086 //端口 spring: application: name: eureka-server //指定當前服務名 eureka: client: service-url: defaultZone: http://localhost:10086/eureka //服務注冊的地址,將當前服務注冊到eureka中.這里是將自己注冊要自己.必須要帶 /eureka instance: prefer-ip-address: true //設置eureka服務的IP地址 ip-address: 127.0.0.1 //設置為本機,如果不設置,默認就為本機IP ~~~ 打開 [http://localhost:10086/](http://localhost:10086/) 可以看到服務. ## 用戶服務客戶端 導入依賴: ~~~ <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId> <version>2.0.1.RELEASE</version> </dependency> ~~~ 啟動類: ~~~ package com.like; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.client.discovery.EnableDiscoveryClient; import tk.mybatis.spring.annotation.MapperScan; @SpringBootApplication @MapperScan("com.like.mapper") @EnableDiscoveryClient //因為spring-cloud 里面有多個注冊中心,所以這里使用EnableDiscoveryClient注解,而不是EnableEurekaClient public class UserServer { public static void main(String[] args) { SpringApplication.run(UserServer.class); } } ~~~ 配置: ~~~ server: port: 8081 //端口 spring: application: name: user-server //當前服務ID datasource: url: jdbc:mysql://192.168.10.10:3306/jdbc username: homestead password: secret eureka: client: service-url: defaultZone: http://localhost:10086/eureka/ //注冊中心的地址 mybatis: type-aliases-package: com.like.pojo //pojo別名 ~~~ ## 調用服務客戶端 配置文件: ~~~ server: port: 8082 spring: application: name: consumer-server eureka: client: service-url: defaultZone: http://localhost:10086/eureka/ ~~~ 啟動類: ~~~ package com.like; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.client.discovery.EnableDiscoveryClient; import org.springframework.context.annotation.Bean; import org.springframework.web.client.RestTemplate; @SpringBootApplication @EnableDiscoveryClient public class ConsumerServer { public static void main(String[] args) { SpringApplication.run(ConsumerServer.class); } @Bean public RestTemplate restTemplate() { return new RestTemplate(); } } ~~~
