一.概述
在第十一章节,我们已经安装了nacos的服务端,本章节把我们的微服务注册到nacos上面.
二.服务注册和发现
1.ccm-mall.pom中有了springcloud-alibaba的版本管理依赖,子工程中实际引入时无需再声明依赖版本号.
<!--springcloud alibaba版本管理依赖-->
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-alibaba-dependencies</artifactId>
<version>2.1.2.RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>
2.server.pom中实际引入nacos客户端的maven依赖.
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>
3.yml配置文件.
配置文件中增加spring.cloud.nacos相关配置,根据实际信息填入
server:
port: 1002 #服务端口
spring:
application:
name: server-user #服务名称
datasource:
username: root
password: Test2016@
url: jdbc:mysql://47.96.131.15:3306/user?allowMultiQueries=true&useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=GMT%2B8&autoReconnect=true
type: com.alibaba.druid.pool.DruidDataSource
cloud:
nacos:
discovery:
server-addr: 47.96.131.1811:8848
mybatis-plus:
typeAliasesPackage: com.ccm.server.user.dao.mysql.domain #数据库实体类包
mapper-locations: classpath:mappering/*.xml #xml文件扫描
3.服务启动类加上@EnableDiscoveryClient注解,表示开启服务注册和发现.
package com.ccm.server.user;
import com.baomidou.mybatisplus.extension.plugins.PaginationInterceptor;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Import;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
/**
* @Description server-user服务启动类
* @Author zhouzhiwu
* @CreateTime 2020/07/03 14:04
*/
@EnableDiscoveryClient //注册中心客户端
@ComponentScan(basePackages = "com.ccm")
@EnableSwagger2
@MapperScan(basePackages = "com.ccm.server.user.dao.mysql.mapper")
@SpringBootApplication //声明为一个启动类
@Import(value = PaginationInterceptor.class)
public class ServerUserApplication {
public static void main(String[] args) {
SpringApplication.run(ServerUserApplication.class,args);
}
}
4.启动微服务.
