java电商项目搭建-------地址模块

努力好了，时间会给你答案。--------magic_guo

对于地址模块的搭建就比较简单了，以下我梳理了地址模块的一些信息；直接看图：
地址模块展示栏：

从上图中可以看地址模块的一些操作：
功能分析：

值得注意的是，添加地址是有两种操作：
1、添加的地址是否设为默认地址；
这就意味我们要做一个判断，这里牵涉了两个sql语句：①.插入这条地址信息；②.将该用户的其他默认地址设置为非默认地址；
2、不判断地址是否设置为默认地址，添加进来的都为非默认地址
直接添加地址，不用考虑用户传进来的是否是默认的，都设为非默认地址，然后让用户自己管理操作；只需设置一个将地址改为默认的接口即可；

我参考了淘宝app的地址管理模块，没有说添加的时候就将此地址设置为默认地址，而是由用户来管理自己的地址；就是我们上述的第二种操作；

看代码：
pom依赖：

        
            com.guo
            shop-common
        

        
            org.springframework.boot
            spring-boot-starter-web
        
        
            org.springframework.cloud
            spring-cloud-starter-config
        
        
            org.springframework.cloud
            spring-cloud-starter-netflix-eureka-client
        

        
            mysql
            mysql-connector-java
            runtime
        
        
            org.springframework.boot
            spring-boot-starter-test
            test
        
    

controller控制接口层：

@RequestMapping("/address")
@RestController
public class AddressController {

    @Autowired
    private IAddressService addressService;

    @RequestMapping("/addAddress")
    @LoginUser
    public ResultEntity addAddress(User user, Address address) {

        if (user.getId() == null) {
            return ResultEntity.error("还未登录，请登录");
        }
        address.setUid(user.getId());

        boolean insert = addressService.insert(address);

        return ResultEntity.success(insert);
    }

    @RequestMapping("/updateAddress")
    @LoginUser
    public ResultEntity updateAddress(User user, Integer addressId, Address address) {

        address.setUid(user.getId());
        EntityWrapper
 addressEntityWrapper = new EntityWrapper<>();
        addressEntityWrapper.eq("id", addressId);
        addressEntityWrapper.eq("uid", user.getId());

        boolean update = addressService.update(address, addressEntityWrapper);

        return ResultEntity.success(update);
    }

    @RequestMapping("/setDefAddress")
    @LoginUser
    public ResultEntity setDefAddress(User user, Integer addressId) {

        addressService.setDefAddress(user.getId(), addressId);

        return ResultEntity.success();
    }

    @RequestMapping("/delAddress")
    @LoginUser
    public ResultEntity delAddress(User user, Integer addressId) {

        boolean b = addressService.deleteById(addressId);

        return ResultEntity.success(b);
    }

    @RequestMapping("/getAllAddress")
    @LoginUser
    public ResultEntity getAllAddress(User user) {

        EntityWrapper
 addressEntityWrapper = new EntityWrapper<>();
        addressEntityWrapper.eq("uid", user.getId());
        List
 addresses = addressService.selectList(addressEntityWrapper);

        return ResultEntity.success(addresses);
    }
}

sevice接口层：

public interface IAddressService extends IService
 {

    void setDefAddress(Integer id, Integer addressId);
}

servicesImpl实现层：

@Service
public class AddressServiceImpl extends ServiceImpl implements IAddressService {

    @Override
    @Transactional
    public void setDefAddress(Integer uid, Integer addressId) {
        // 将所有地址设为非默认地址
        baseMapper.setAllAddressToDef(uid);
        // 将此id的地址位置为默认地址
        baseMapper.setDefAddress(uid, addressId);
    }
}

mapper层：

public interface AddressMapper extends baseMapper
 {

    void setAllAddressToDef(Integer uid);

    void setDefAddress(@Param("uid") Integer uid, @Param("addressId") Integer addressId);
}

mapper.xml：

    
        update
            t_address
        set
            def = 0
        where
            uid = #{uid}
    

    
        update
            t_address
        set
            def = 1
        where
            uid = #{uid} and id = #{addressId}
    
    

配置文件：

spring:
  cloud:
    config:
      uri: http://localhost:9999
      profile: shop-address, eureka-client, log, datasource
      name: application
mybatis-plus:
  mapper-locations: classpath:mapper/*.xml
  type-aliases-package: com.guo

config配置文件：

spring:
  application:
    name: shop-address
server:
  port: 8012

启动类：

@SpringBootApplication(scanbasePackages = "com.guo")
@EnableEurekaClient
@MapperScan("com.guo.mapper")
public class ShopAddressApplication {

    public static void main(String[] args) {
        SpringApplication.run(ShopAddressApplication.class, args);
    }

}

完工！
