SpringCloud2.x的简单实践教程(一)
网上有很多springCloud1.x的教程，可以直接参考博客进行学习比如纯洁的微笑的博客，讲解的很清晰。如果想要学springboot2.x的东西那么就要去网上直接找资料了，多看官方文档也是可以的
第一步 服务端配置。
使用Spring Boot 2.0.2.RELEASE和Spring Cloud Finchley.SR2官方正式版进行项目构建,创建名字为eureka-server的Spring Boot工程
spring-cloud-starter-netflix-eureka-server服务注册中心依赖
pom.xml
<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">

第二步 创建注册中心
springcloudserver
pom.xml
<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>
<groupId>cn.codepeople</groupId>
<artifactId>eureka-server</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>eureka-server</name>
<description>Demo project for Spring Boot</description>
<properties>
<java.version>1.8</java.version>
</properties>
<parent>
<groupId>cn.codepeople.base</groupId>
<artifactId>springcloud-base</artifactId>
<version>1.0.0-SNAPSHOT</version>
</parent>
<dependencies>
<!-- eureka 服务端 -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
</dependency>
</dependencies>
</project>
第三步 添加注册中心配置文件yml
application.yml
spring:
application:
name: eureka-server
server:
port: 8761
第四步 创建启动文件EurekaServerApplication.java
EurekaServerApplication.java
package cn.codepeople;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
/**
* @description 注册服务中心
* @author 刘仁
* @2019年6月25日 14:52:13
*/
@EnableEurekaServer
@SpringBootApplication
public class EurekaServerApplication {
public static void main(String[] args) throws Exception {
SpringApplication.run(EurekaServerApplication.class, args);
}
}
第五步 启动EurekaServerApplication.java注册中心
访问地址：http://localhost:8761/
第六步 创建客户端
创建客户端eureka-client
pom.xml
<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>
<groupId>cn.codepeople</groupId>
<artifactId>eureka-client</artifactId>
<version>0.0.1-SNAPSHOT</version>
<parent>
<groupId>cn.codepeople.base</groupId>
<artifactId>springcloud-base</artifactId>
<version>1.0.0-SNAPSHOT</version>
</parent>
<properties>
<java.version>1.8</java.version>
</properties>
<dependencies>
<!-- eureka 客户端 -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
<!-- springboot web模块 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>
</project>
第七步 创建客户端的yml配置文件
application.yml
spring:
application:
name: eureka-client
server:
port: 8080
eureka:
client:
serviceUrl:
defaultZone: http://localhost:8761/eureka/
第八步 编写Controller
HelloController.java
package cn.codepeople.controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class HelloController {
@GetMapping("/hello")
public String index() {
return "Hello World!";
}
}
第九步 编写客户端启动程序
EurekaClientApplication.java
package cn.codepeople;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* @description 客户端
* @author 刘仁
* @2019年6月25日 14:52:13
*/
@SpringBootApplication
public class EurekaClientApplication {
public static void main(String[] args) throws Exception {
SpringApplication.run(EurekaClientApplication.class, args);
}
}
然后刷新地址:http://localhost:8761/
效果：
访问地址：http://localhost:8080/hello
