springcloud集成nacos完成项目

it2022-05-05 137

下载nacos 1.在nacos官网下载nacos 2.解压nacos，启动创建项目 1.创建一个maven的空项目（项目名为springcloudDenmo） 2.然后在该项目下创建四个spring Initializr项目（springcloud-api、springcloud-beans、springcloud-boot、springcloud-nacos）添加依赖 1.springcloudDenmo添加依赖

2.springcloud-beans添加依赖

3.springcloud-api添加依赖

项目结构 1.传统项目我们都是从dao->service->controller 2.现在项目首先由beans开始到api再到boot（boot指的是本地的运行启动，运用nacos的时候在nacos启动）。 3.在beans中我们创建dao、dto、entry、vo，resources创建mapper放置配置文件 4.在api下创建controller、cinfg、mq、service、utils 5.在boot的resource下properties文件和yml文件 properties文件

spring.profiles.active=dev spring.application.name=springcloudDemo debug=true

yml文件

spring: #数据源配置 datasource: druid: db-type: mysql driver-class-name: com.mysql.jdbc.Driver url: jdbc:mysql://localhost:3306/test?characterEncoding=utf-8 username: r password: 1 server: port: 8080 servlet: context-path: /jdrx-demo info: name: springcloudDemo description: springcloudDemo version: 1.0.0

6.nacos下创建yml文件

spring: application: name: springcloudDemo cloud: nacos: config: server-addr: 192.168.60.51:8848 file-extension: yml group: demo profiles: active: d

2.当启动测试类后，我们将自动生成的xml文件和dao文件和po文件分别复制进入mapper、dao、entry下下· 3.在api下service书写简单的服务方法 4.在api下controller中书写接口启动项目 1.在springcloud-boot下

package com.jdrx.springcloudboot; 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.transaction.annotation.EnableTransactionManagement; @EnableTransactionManagement @ComponentScan("com") @SpringBootApplication @MapperScan("com.jdrx.beans.dao") public class SpringcloudBootApplication { public static void main(String[] args) { SpringApplication.run(SpringcloudBootApplication.class, args); } }

2.在springcloud-nacos下

package com.jdrx.springcloudnacos; 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.transaction.annotation.EnableTransactionManagement; @SpringBootApplication @EnableTransactionManagement @ComponentScan("com") @MapperScan("com.jdrx.beans.dao") public class SpringcloudNacosApplication { public static void main(String[] args) { SpringApplication.run(SpringcloudNacosApplication.class, args); } }
