SpringCloud之服务提供与调用(Ribbon,Feign)

本系列介绍的配置均基于 Spring Boot 2.0.1.RELEASE 版本和 Spring Cloud Finchley.SR1

eureka注册续约流程

1. 启动注册中心
2. 服务提供者生产服务并注册到服务中心中
3. 消费者从服务中心中获取服务并执行

 

 

 

 

 

服务提供

1.在spring-cloud-manage下创建一个子项目producer-service

pom.xml文件如下

<?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>spring-cloud-manage</artifactId>
        <groupId>org.springcloudmanage</groupId>
        <version>1.0</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>
    <artifactId>producer-service</artifactId>
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <maven.compiler.source>1.8</maven.compiler.source>
        <maven.compiler.target>1.8</maven.compiler.target>
    </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-client</artifactId>
        </dependency>
    </dependencies>
    <build>
        <finalName>producer-service</finalName>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
</project>

2.创建启动类

Finchley版本已经不需要添加@EnableDiscoveryClient注解,Spring Cloud会自动识别。

@SpringBootApplication
public class ProducerServiceApplication {
    public static void main(String[] args) {
        SpringApplication.run(ProducerServiceApplication.class, args);
    }
}

3.配置文件

spring.application.name=producer-service
server.port=9001
#eureka
eureka.client.serviceUrl.defaultZone=http://localhost:8001/eureka/

• spring.application.
