前言

构建服务方子工程store-user-service，集成mybatis-plus、nacos-discovery，提供消费者用户类的增删改查功能。

1、微服务子工程store-user-service

1.1、创建子工程store-user-service

创建Module，store-user-service

1.2、修改pom.xml配置

加入依赖：springWeb、mybatis-plus、nacos-discovery、公共库等

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <scope>runtime</scope>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-autoconfigure</artifactId>
        </dependency>
        <dependency>
            <groupId>com.kelvin</groupId>
            <artifactId>store-common</artifactId>
        </dependency>
        <dependency>
            <groupId>com.google.code.gson</groupId>
            <artifactId>gson</artifactId>
            <version>2.7</version>
        </dependency>

		<dependency>
		    <groupId>com.baomidou</groupId>
		    <artifactId>mybatis-plus-boot-starter</artifactId>
		    <version>3.5.2</version>
		</dependency>
		<!--导入数据驱动-->
		<dependency>
		     <groupId>com.mysql</groupId>
		     <artifactId>mysql-connector-j</artifactId>
		     <scope>runtime</scope>
		     <version>8.0.33</version>
		 </dependency>

1.3、修改application.yml配置

server:
  port: 7776
spring:
  application:
    name: store-user-service
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848  #Nacos server 的地址

  datasource:
    username: root
    password: root
    url: jdbc:mysql://127.0.0.1:3306/spring
    driver-class-name: com.mysql.cj.jdbc.Driver
    
mybatis-plus:
  configuration:
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl #开启sql日志

1.4、配置plus分页

1.4.1、添加依赖

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-lang3</artifactId>
    <version>3.12.0</version>
</dependency>

1.4.2、添加配置

import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/***
 * @title MybatisPlusConfig
 * @desctption <TODO description class purpose>
 * @author Administrator
 * @create 2023/6/21 18:06
 **/
@Configuration
public class MybatisPlusConfig {
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor(){
        MybatisPlusInterceptor mybatisPlusInterceptor = new MybatisPlusInterceptor();
        mybatisPlusInterceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
        return mybatisPlusInterceptor;
    }
}

1.5、配置nacos，作为服务提供者

1.5.1、配置pom.xml

	<dependency>
        <groupId>com.alibaba.cloud</groupId>
        <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
    </dependency>

1.5.2、配置application.yml

spring:
  application:
    name: app-provider-service #服务名
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848

1.5.3、配置启动类，开启Nacos discovery

@EnableDiscoveryClient

启动应用，查看nacos后台

总结

以上就是今天要讲的内容，本文简单介绍了store-user-service的使用，对外提供提供【用户根据ID查询、分页查询、增加、删除、修改接口】，为分布式系统提供消费端用户的微服务功能。
