电商项目（四）--后台系统架构初步搭建

1. 百战商城服务设计

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>
        <!--mapper-->
        <dependency>
            <groupId>com.bjsxt</groupId>
            <artifactId>common_mapper</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>

        <!-- utils -->
        <dependency>
            <groupId>com.bjsxt</groupId>
            <artifactId>common_utils</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>

        <!--Spring Boot Web Starter-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <!--Spring Cloud Eureka Client Starter-->
        <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>
        <!-- 资源拷贝插件-->
        <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
