## 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>
    		
    		<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
