一、创建模块(microservice-consumer-movie-feign-with-hystrix)
二、pom.xml文件
microservice-spring-cloud com.jacky 1.0-SNAPSHOT 4.0.0 microservice-consumer-movie-feign-with-hystrix jar UTF-8 UTF-8 1.8 org.springframework.boot spring-boot-starter-web org.springframework.cloud spring-cloud-starter-eureka org.springframework.boot spring-boot-starter-actuator org.springframework.cloud spring-cloud-starter-feign org.springframework.cloud spring-cloud-starter-hystrix com.spotify docker-maven-plugin build-image install build http://192.168.6.130:5678 true ${docker.repostory}/${docker.image.prefix}/${project.artifactId}:${project.version} java:openjdk-8-jdk-alpine ["java", "-jar", "/${project.build.finalName}.jar"] / ${project.build.directory} ${project.build.finalName}.jar
三、配置文件application.yml
spring:
application:
name: microservice-consumer-movie-feign-with-hystrix
server:
port: 7901
eureka:
client:
healthcheck:
enabled: true
serviceUrl:
defaultZone: http://jacky:admin@peer1:8761/eureka/,http://jacky:admin@peer2:8762/eureka/,http://jacky:admin@peer3:8763/eureka/
instance:
prefer-ip-address: true
instance-id: ${spring.application.name}:${spring.cloud.client.ipAddress}:${spring.application.instance_id:${server.port}}四、实体类User.java
package com.jacky.cloud.entity;
import java.math.BigDecimal;
public class User {
private Long id;
private String username;
private String name;
private Short age;
private BigDecimal balance;
public Long getId() {
return this.id;
}
public void setId(Long id) {
this.id = id;
}
public String getUsername() {
return this.username;
}
public void setUsername(String username) {
this.username = username;
}
public String getName() {
return this.name;
}
public void setName(String name) {
this.name = name;
}
public Short getAge() {
return this.age;
}
public void setAge(Short age) {
this.age = age;
}
public BigDecimal getBalance() {
return this.balance;
}
public void setBalance(BigDecimal balance) {
this.balance = balance;
}
}五、生产者发生错误时使用的类(HystrixClientFallback.java)
package com.jacky.cloud.feign;
import org.springframework.stereotype.Component;
import com.jacky.cloud.entity.User;
@Component
public class HystrixClientFallback implements UserFeignClient {
@Override
public User findById(Long id) {
User user = new User();
user.setId(0L);
return user;
}
}六、feign客户端UserFeignClient.java
package com.jacky.cloud.feign;
import com.jacky.cloud.entity.User;
import org.springframework.cloud.netflix.feign.FeignClient;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@FeignClient(name = "microservice-provider-user", fallback = HystrixClientFallback.class)
public interface UserFeignClient {
@RequestMapping(value = "/simple/{id}", method = RequestMethod.GET)
public User findById(@PathVariable("id") Long id);
}七、MovieController.java
package com.jacky.cloud.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;
import com.jacky.cloud.entity.User;
import com.jacky.cloud.feign.UserFeignClient;
@RestController
public class MovieController {
@Autowired
private UserFeignClient userFeignClient;
@GetMapping("/movie/{id}")
public User findById(@PathVariable Long id) {
return this.userFeignClient.findById(id);
}
}八、启动类
package com.jacky.cloud;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.circuitbreaker.EnableCircuitBreaker;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.feign.EnableFeignClients;
@SpringBootApplication
@EnableEurekaClient
@EnableFeignClients
@EnableCircuitBreaker
public class ConsumerMovieFeignApplication {
public static void main(String[] args) {
SpringApplication.run(ConsumerMovieFeignApplication.class, args);
}
