服务消费者

创建项目sercice-order

Maven依赖

<parent>             <groupId>org.springframework.boot</groupId>             <artifactId>spring-boot-starter-parent</artifactId>             <version>1.5.2.RELEASE</version>             <relativePath /> <!-- lookup parent from repository -->       </parent>         <properties>             <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>             <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>             <java.version>1.8</java.version>       </properties>         <dependencies>             <dependency>                   <groupId>org.springframework.cloud</groupId>                   <artifactId>spring-cloud-starter-eureka</artifactId>             </dependency>             <dependency>                   <groupId>org.springframework.cloud</groupId>                   <artifactId>spring-cloud-starter-ribbon</artifactId>             </dependency>             <dependency>                   <groupId>org.springframework.boot</groupId>                   <artifactId>spring-boot-starter-web</artifactId>             </dependency>               <dependency>                   <groupId>org.springframework.boot</groupId>                   <artifactId>spring-boot-starter-test</artifactId>                   <scope>test</scope>             </dependency>       </dependencies>         <dependencyManagement>             <dependencies>                   <dependency>                        <groupId>org.springframework.cloud</groupId>                        <artifactId>spring-cloud-dependencies</artifactId>                        <version>Dalston.RC1</version>                        <type>pom</type>                        <scope>import</scope>                   </dependency>             </dependencies>       </dependencyManagement>         <build>             <plugins>                   <plugin>                        <groupId>org.springframework.boot</groupId>                        <artifactId>spring-boot-maven-plugin</artifactId>                   </plugin>             </plugins>       </build>         <repositories>             <repository>                   <id>spring-milestones</id>                   <name>Spring Milestones</name>                   <url>https://repo.spring.io/milestone</url>                   <snapshots>                        <enabled>false</enabled>                   </snapshots>             </repository>       </repositories>

 

application.yml配置

eureka:   client:     serviceUrl:       defaultZone: http://localhost:8888/eureka/ server:   port: 8764 spring:   application:     name: service-order

 

编写service,调用service-member

@SuppressWarnings("unchecked") @Service public class MemberService {       @Autowired       RestTemplate restTemplate;         public List<String> getOrderByUserList() {             return restTemplate.getForObject("http://service-member/getUserList", List.class);       }          }

演示效果

@EnableEurekaClient @SpringBootApplication public class AppOrder {         public static void main(String[] args) {             SpringApplication.run(AppOrder.class, args);       }         @Bean       @LoadBalanced       RestTemplate restTemplate() {             return new RestTemplate();       }   }

 

 

在工程的启动类中,通过@EnableDiscoveryClient向服务中心注册；并且向程序的ioc注入一个bean: restTemplate;并通过@LoadBalanced注解表明这个restRemplate开启负载均衡的功能。
