#                              Easymall项目分布式拆分整合(九） #

--------------------

# 一.购物车系统搭建 #

# 1.步骤（经典六步） #

## 1.1创建一个quickstart的maven工程(src/main/resources) ##

## 1.2pom继承parent,依赖common ##

### 1.pom继承parent ###

### **2.依赖common** ###

## 1.3后台user系统需要的其他依赖 ##

*  **jdbc,mysql,mybatis**
 *  **redis暂留**

<dependencies>
      	<dependency>
      		<groupId>org.springframework.boot</groupId>
      		<artifactId>spring-boot-starter-jdbc</artifactId>
      	</dependency>
      	<dependency>
      		<groupId>mysql</groupId>
      		<artifactId>mysql-connector-java</artifactId>
      	</dependency>
      	<dependency>
      		<groupId>org.mybatis.spring.boot</groupId>
           	<artifactId>mybatis-spring-boot-starter</artifactId>	
      	</dependency>
      	<dependency>
    		<groupId>org.apache.httpcomponents</groupId>
    		<artifactId>httpclient</artifactId>
    	</dependency>
        <dependency>
          <groupId>junit</groupId>
          <artifactId>junit</artifactId>
          <version>3.8.1</version>
          <scope>test</scope>
        </dependency>
        <dependency>
        	<groupId>cn.tedu</groupId>
        	<artifactId>springboot-common-easymall</artifactId>
        	<version>0.0.1-SNAPSHOT</version>
        </dependency>
      </dependencies>

## 1.4application.properties文件 ##

*  端口8094
 *  datasource
 *  mybatis
 *  redis

server.port=8094
    
    spring.datasource.driver-class-name=com.mysql.jdbc.Driver
    spring.datasource.url=jdbc:mysql:///easydb?useUnicode=true&characterEncoding=utf8&autoReconnect=true&allowMultiQueries=true
    spring.datasource.password=root
    spring.datasource.username=root
    
    mybatis.configuration.mapUnderscoreToCamelCase=true
    mybatis.mapperLocations=classpath:mapper/*.xml
    mybatis.typeAliasesPackage=com.jt.common.pojo
    
    redis.nodes=10.9.151.60:6379
    redis.maxTotal=200
    redis.maxIdle=8
    redis.minIdle=3
    
    http.maxTotal = 100
    http.defaultMaxPerRoute = 20
    http.connectTimeout=1000
    http.connectionRequestTimeout=500
    http.socketTimeout=10000
    http.staleConnectionCheckEnabled=true

## 1.5启动类(MapperScan) ##

*  CartService从之前单体easymall粘贴到当前项目中(将方法注释,等待每个功能开发的重新编写)
 *  扫描接口mapper的包
 *  CartMapper(重新导入Cart的包名,common)
 *  CartMapper.xml(修改namespce对应新的接口全路径)
 *  启动类

@SpringBootApplication
    @MapperScan("com.jt.cart.mapper")
    public class StarterCart {
    	public static void main(String[] args) {
    		SpringApplication.run(StarterCart.class, args);
    	}
    }

## 1.6nginx和hosts文件 ##

### 1.nginx配置 ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0xpdVk1MjE_size_16_color_FFFFFF_t_70 1][]

### 2.hosts文件 ###

<table style="margin-left:1.0833in;"> 
 <tbody> 
  <tr> 
   <td style="border-color:#a3a3a3;vertical-align:top;width:1.0111in;"> <p style="margin-left:0in;"><strong>127.0.0.1</strong></p> </td> 
   <td style="border-color:#a3a3a3;vertical-align:top;width:1.8506in;"> <p style="margin-left:0in;"><strong>cart.easymall.com</strong></p> </td> 
  </tr> 
 </tbody> 
</table>

# 二.购物车系统接口方法 #

# 1.查询我的购物车 #

## 1.CartController ##

//查询我的购物车后台系统逻辑
    	@RequestMapping("queryList/{userId}")
    	public List<Cart> queryMyCart(@PathVariable String userId){
    		return cartService.queryMyCart(userId);
    	}

## 2.CartService没有变动 ##

@Autowired
    	private CartMapper cartMapper;
    	public List<Cart> queryMyCart(String userId) {
    		List<Cart> cartList=cartMapper.queryMyCart(userId);
    		return cartList;
    	}

## 3.效果实现 ##

# 2.新增我的购物车商品数据 #
