注意:这个章节,请结合前几章节一起使用,因为其要调用上一章节的服务
1、pom.xml
<?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" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.3.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.test</groupId> <artifactId>eureka-client-movie</artifactId> <version>0.0.1-SNAPSHOT</version> <name>eureka-client-movie</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> <spring-cloud.version>Greenwich.SR1</spring-cloud.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-server</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>${spring-cloud.version}</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> </project>
2、添加application.yml配置
server:
port: 8664
user:
userServicePath: http://localhost:8663/user/
spring:
application:
name: eureka-client-movie
eureka:
instance:
hostname: localhost
prefer-ip-address: true
instance-id: ${spring.application.name}:${spring.application.instance_id:${server.port}}
client:
serviceUrl:
defaultZone: http://${eureka.instance.hostname}:8661/eureka
3、在启动类添加注解
package com.test.eurekaclientmovie; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.netflix.eureka.EnableEurekaClient; import org.springframework.context.annotation.Bean; import org.springframework.web.client.RestTemplate; @SpringBootApplication @EnableEurekaClient public class EurekaClientMovieApplication { @Bean public RestTemplate restTemplate(){ return new RestTemplate(); } public static void main(String[] args) { SpringApplication.run(EurekaClientMovieApplication.class, args); } }
4、MovieController.java
package com.test.eurekaclientmovie.controller; import com.test.eurekaclientmovie.entity.User; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Value; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RestController; import org.springframework.web.client.RestTemplate; @RestController public class MovieController { @Autowired private RestTemplate restTemplate; @Value("${user.userServicePath}") private String userServicePath; /* @Autowired private LoadBalancerClient loadBalancerClient;*/ @GetMapping("/movie/{id}") public User findById(@PathVariable Long id) { //请用虚拟ip return restTemplate.getForObject(this.userServicePath+id, User.class); } /** * 配置单一的方法进行轮询 * @return *//* @GetMapping("/test") public String test() { //请用虚拟ip ServiceInstance serviceInstance =loadBalancerClient.choose("eureka-client-user"); System.out.println(serviceInstance.getHost()+":"+serviceInstance.getPort()); return "1"; }*/ }
5、User.java
package com.test.eurekaclientmovie.entity; import java.io.Serializable; import java.math.BigDecimal; public class User implements Serializable { private Long id; private String name; private String username; private BigDecimal balance; private short age; public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public BigDecimal getBalance() { return balance; } public void setBalance(BigDecimal balance) { this.balance = balance; } public short getAge() { return age; } public void setAge(short age) { this.age = age; } }
6、实现服务之间的调用,如果访问下面URL有返回值,说明实现了服务之间的调用了,没有实现,请仔细检查配置,也可以留言
http://localhost:8664/movie/1
7、查看eureka-server的情况
http://localhost:8661/
如下图所示
SpringCloud之Eureka-Client使用RestTemplate实现服务之间的调用
