## 2. 创建common\_item项目 ##

① pom文件

<?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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
        <parent>
            <artifactId>bz_parent</artifactId>
            <groupId>com.bjsxt</groupId>
            <version>1.0-SNAPSHOT</version>
        </parent>
        <modelVersion>4.0.0</modelVersion>
    
        <artifactId>common_item</artifactId>
    
        <dependencies>
            
            <dependency>
                <groupId>com.bjsxt</groupId>
                <artifactId>common_mapper</artifactId>
                <version>1.0-SNAPSHOT</version>
            </dependency>
    
            
            <dependency>
                <groupId>com.bjsxt</groupId>
                <artifactId>common_utils</artifactId>
                <version>1.0-SNAPSHOT</version>
            </dependency>
    
            
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
    
            
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
            </dependency>
    
    
    
        </dependencies>
    
    
    </project>

② 创建配置文件

spring:
      application:
        name: common-item
      datasource:
        driverClassName: com.mysql.jdbc.Driver
        url: jdbc:mysql://localhost:3306/bz_shop?characterEncoding=UTF-8
        username: root
        password: root
        type: com.alibaba.druid.pool.DruidDataSource
    
    server:
      port: 9010
    
    eureka:
      client:
        serviceUrl:
          defaultZone: http://eureka-server:8761/eureka/

③ 修改mapper的pom文件，添加资源拷贝插件

<build>
            
            <resources>
                <resource>
                    <directory>src/main/java</directory>
                    <includes>
                        <include>**/*.xml</include> </includes> </resource> <resource> <directory>src/main/resources</directory> <includes> <include>**/*.xml</include>
                    </includes>
                </resource>
            </resources>
        </build>

④ 创建启动类

package com.bjsxt.item;
    
    import org.mybatis.spring.annotation.MapperScan;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
    
    /** * 通用服务 */
    @SpringBootApplication
    @EnableDiscoveryClient
    @MapperScan("com.bjsxt.mapper")
    public class CommonItemApplication { 
        public static void main(String[] args) { 
            SpringApplication.run(CommonItemApplication.class,args);.
        }
    }

⑤ 修改Host文件添加注册中心域名与IP的映射
