springcloud用法
使用springcloud搭建微服务肯定要在父工程下面编写子工程
一.搭建eureka注册中心
1. 创建maven项目(在springboot项目下建立子工程eureka-server)
2. 导入坐标
| <dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
</dependency>
</dependencies> |
3. 创建引导类
@SpringBootApplication
@EnableEurekaServer //添加注解 表名服务,声明这个应用时EurekaServer
public class EurekaManager {
public static void main(String[] args) {
SpringApplication.run(EurekaManager.class,args);
}
} |
4. 编写配置文件
编写application.yml文件
server:
port: 10086
spring:
application:
name: eureka-server #自己注册的serviceId,即注册名称
eureka:
client:
service-url:
defaultZone: http://127.0.0.1:10086/eureka
register-with-eureka: true #注册自己,默认为true
fetch-registry: true #拉取服务,默认为true
|
5. 效果截图
二.搭建提供者,user-service
提供者user-service对于注册中心而言还是客户端
1. 创建maven工程user-service
2. 导入坐标
<!--添加坐标-->
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
<dependency>
<groupId>tk.mybatis</groupId>
<artifactId>mapper-spring-boot-starter</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
</dependencies> |
3. 编写启动类
package com.ahd;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.context.annotation.Bean;
