如何使用SpringCloudAliBaba技术栈搭建微服务环境

首先创建一个父模块（怎么创建应该就不用多说了吧，重点是依赖这些东西，我这里是大致拿出我其中的一个项目做例子）

<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>com.gq</groupId><artifactId>Shopping</artifactId><version>1.0-SNAPSHOT</version><packaging>pom</packaging><!-- 子模块 --><modules>

</project>

列举其中一个有数据源的子服务模块：

<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>com.gq</groupId><artifactId>Shopping</artifactId><version>1.0-SNAPSHOT</version></parent><groupId>com.gq</groupId><artifactId>shopping_admin_service</artifactId><version>0.0.1-SNAPSHOT</version><name>shopping_admin_service</name><description>shopping_admin_service</description><url/><licenses><license/></licenses><developers><developer/></developers><scm><connection/><developerConnection/><tag/><url/></scm><properties><java.version>17</java.version></properties><dependencies><!-- MyBatisPlus --><dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-boot-starter</artifactId></dependency><!-- mysql驱动 --><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><scope>runtime</scope></dependency><dependency><groupId>com.gq</groupId><artifactId>shopping_common</artifactId><version>0.0.1-SNAPSHOT</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><!-- dubbo --><dependency><groupId>org.apache.dubbo</groupId><artifactId>dubbo-spring-boot-starter</artifactId></dependency><dependency><groupId>org.apache.dubbo</groupId><artifactId>dubbo-registry-nacos</artifactId></dependency><!-- nacos --><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId></dependency><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>

（1）启动类

package com.gq.shopping_admin_service;import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;
import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.context.annotation.Bean;@SpringBootApplication
@MapperScan("com.gq.shopping_admin_service.mapper")
@EnableDiscoveryClient
@EnableDubbo
@RefreshScope
public class ShoppingAdminServiceApplication {public static void main(String[] args) {SpringApplication.run(ShoppingAdminServiceApplication.class, args);}// 分页插件@Beanpublic MybatisPlusInterceptor mybatisPlusInterceptor() {MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));return interceptor;}
}

基本上都是这样创建的！
