这篇文章主要介绍SpringCloud分布式微服务b2b2c电子商务分布式微服务中docker-feign-hystrix的示例分析，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！
一、创建模块（microservice-consumer-movie-feign-with-hystrix）
二、pom.xml文件
<?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"> <parent> <artifactId>microservice-spring-cloud</artifactId> <groupId>com.jacky</groupId> <version>1.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>microservice-consumer-movie-feign-with-hystrix</artifactId> <packaging>jar</packaging> <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.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-feign</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-hystrix</artifactId> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>com.spotify</groupId> <artifactId>docker-maven-plugin</artifactId> <executions> <!--设置在执行maven 的install时构建镜像--> <execution> <id>build-image</id> <phase>install</phase> <goals> <goal>build</goal> </goals> </execution> </executions> <configuration> <!--安装了docker的主机，并且打开了api remote接口设置--> <dockerHost>http://192.168.6.130:5678</dockerHost> <pushImage>true</pushImage><!--设置上传镜像到私有仓库，需要docker设置指定私有仓库地址--> <!--镜像名称--> <imageName>${docker.repostory}/${docker.image.prefix}/${project.artifactId}:${project.version}</imageName> <!--镜像的基础版本--> <baseImage>java:openjdk-8-jdk-alpine</baseImage> <!--镜像启动参数--> <entryPoint>["java", "-jar", "/${project.build.finalName}.jar"]</entryPoint> <resources> <resource> <targetPath>/</targetPath> <directory>${project.build.directory}</directory> <include>${project.build.finalName}.jar</include> </resource> </resources> </configuration> </plugin> </plugins> </build> </project>
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); } }
