5.3 应用绑定服务类型

5.3.1 系统设计

为应用绑定服务类型即指定应用使用哪些服务类型，数据模型设计如下 :

5.3.2 交易服务-获取平台服务类型(接口①)

绑定服务类型页面，页面中列表出服务类型。

5.3.1.1 接口定义

1、接口描述：查询平台支持的所有服务类型

2、接口定义如下：PayChannelService

package com.huiminpay.transaction.api;

/**
 \* 支付渠道服务 管理平台支付渠道，原始支付渠道，以及相关配置
 */
public interface PayChannelService {

  /**
  \* 获取平台服务类型
  \* @return
  */
  List<PlatformChannelDTO> queryPlatformChannel() throws BusinessException;
}
5.3.1.2 接口实现

定义PayChannelServiceImpl类及queryPlatformChannel实现方法：

package com.huiminpay.transaction.service;

import com.huiminpay.transaction.api.PayChannelService;
import com.huiminpay.transaction.api.dto.PlatformChannelDTO;
import com.huiminpay.transaction.convert.PlatformChannelConvert;
import com.huiminpay.transaction.entity.PlatformChannel;
import com.huiminpay.transaction.mapper.PlatformChannelMapper;
import org.springframework.beans.factory.annotation.Autowired;

import java.util.List;

@org.apache.dubbo.config.annotation.Service
public class PayChannelServiceImpl implements PayChannelService {

  @Autowired
  private PlatformChannelMapper platformChannelMapper;

  @Override
  public List<PlatformChannelDTO> queryPlatformChannel() {
    List<PlatformChannel> platformChannels = platformChannelMapper.selectList(null);
    List<PlatformChannelDTO> platformChannelDTOS = 
        PlatformChannelConvert.INSTANCE.listentity2listdto(platformChannels);
    return platformChannelDTOS;
  }
}

5.3.3 商户平台应用-获取平台服务类型(接口②)

5.3.3.1 接口定义

在商户平台应用工程添加依赖：

<dependency>
  <groupId>com.huiminpay</groupId>
  <artifactId>huiminpay-transaction-api</artifactId>
  <version>1.0-SNAPSHOT</version>
</dependency>

1、接口描述：请求交易服务查询平台支持的所有服务类型

2、接口定义如下：PlatformParamController

package com.huiminpay.merchant.controller;

@Api(value = "商户平台-渠道和支付参数相关", tags = "商户平台-渠道和支付参数", description = "商户平台-渠道和支付参数相关")
@Slf4j
@RestController
public class PlatformParamController {

    @Reference  
    private PayChannelService payChannelService;  

    @ApiOperation("获取平台服务类型")  
    @GetMapping(value="/my/platform-channels")  
    public List<PlatformChannelDTO> queryPlatformChannel(){  
        return payChannelService.queryPlatformChannel();    
    }  
}
5.3.3.2 接口测试

5.3.4 交易服务-绑定服务类型接口(接口③)

点击开启服务为应用绑定服务类型

5.3.4.1 接口定义

1、接口描述：

1）查询出指定应用就否已绑定选定的服务类型

2）如果该应用没有绑定该 服务类型则进行绑定

2、接口定义如下：

在PayChannelService接口中定义bindPlatformChannelForApp

/**  
 \* 为app绑定平台服务类型  
 \* @param appId 应用id  
 \* @param platformChannelCodes 平台服务类型列表  
 */  
void bindPlatformChannelForApp(String appId, String platformChannelCodes) throws BusinessException;
5.3.4.2 接口实现

定义PayChannelServiceImpl类及bindPlatformChannelForApp实现方法：

package com.huiminpay.transaction.service;

import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.huiminpay.transaction.api.PayChannelService;
import com.huiminpay.transaction.entity.AppPlatformChannel;
import com.huiminpay.transaction.mapper.AppPlatformChannelMapper;
import org.apache.dubbo.config.annotation.Service;
import org.springframework.beans.factory.annotation.Autowired;

import java.util.ArrayList;
import java.util.List;

@Service
public class PayChannelServiceImpl implements PayChannelService {
    @Autowired
     private AppPlatformChannelMapper appPlatformChannelMapper;

    @Override  
    @Transactional
    public void bindPlatformChannelForApp(String appId, String platformChannelCodes) throws 
        BusinessException {
        //根据appId和平台服务类型code查询app_platform_channel
        AppPlatformChannel appPlatformChannel = appPlatformChannelMapper.selectOne(
            new LambdaQueryWrapper<AppPlatformChannel>()
            .eq(AppPlatformChannel::getAppId, appId)
            .eq(AppPlatformChannel::getPlatformChannel, platformChannelCodes));
        //如果没有绑定则绑定
        if(appPlatformChannel ==null){
            appPlatformChannel = new AppPlatformChannel();
            appPlatformChannel.setAppId(appId);
            appPlatformChannel.setPlatformChannel(platformChannelCodes);
            appPlatformChannelMapper.insert(appPlatformChannel);
        }
    }
}

5.3.5 商户平台应用-绑定服务类型接口(接口④)

5.3.5.1 接口定义

1、接口描述：请求交易服务为指定应用添加服务类型

2、接口定义如下：

在AppController类中定义bindPlatformForApp方法：

@DubboReference
private PayChannelService payChannelService;


@ApiOperation("绑定服务类型")
@PostMapping(value="/my/apps/{appId}/platform-channels")
@ApiImplicitParams({@ApiImplicitParam(value = "应用id",name = "appId",dataType = "string",paramType = "path"),
                    @ApiImplicitParam(value = "服务类型code",name = "platformChannelCodes",dataType = "string",paramType = "query")
                   })
public void bindPlatformForApp(@PathVariable("appId") String appId, 
                               @RequestParam("platformChannelCodes") String platformChannelCodes){
    payChannelService.bindPlatformChannelForApp(appId,platformChannelCodes);
}
5.3.5.2 接口测试

5.3.6 交易服务-查询服务类型绑定状态

5.3.6.1 接口定义

1、接口描述

1）查询应用是否已经绑定了某个服务类型

2、接口定义如下

1）PayChannelService

/**
   \* 应用是否已经绑定了某个服务类型
   \* @param appId
   \* @param platformChannel
   \* @return 已绑定返回1，否则 返回0
   */
int queryAppBindPlatformChannel(String appId,String platformChannel) throws BusinessException;
5.5.5.2 接口实现

在PayChannelServiceImpl中实现queryAppBindPlatformChannel方法：

@Override
public int queryAppBindPlatformChannel(String appId, String platformChannel) {
    int count = appPlatformChannelMapper.selectCount(
        new QueryWrapper<AppPlatformChannel>().lambda()
        .eq(AppPlatformChannel::getAppId, appId)
        .eq(AppPlatformChannel::getPlatformChannel, platformChannel));
    //已存在绑定关系返回1
    if (count > 0) {
        return 1;
    } else {
        return 0;
    }
}

5.3.7 商户平台-查询服务类型绑定状态

5.3.7.1 接口实现

查询应用是否已经绑定了某个服务类型

在AppController中定义：

@ApiOperation("查询应用是否绑定了某个服务类型")
@ApiImplicitParams({
    @ApiImplicitParam(name = "appId", value = "应用appId", required = true, dataType = "String", paramType = "query"),
    @ApiImplicitParam(name = "platformChannel", value = "服务类型", required = true, dataType = "String", paramType = "query")
})
@GetMapping("/my/merchants/apps/platformchannels")
public int queryAppBindPlatformChannel(@RequestParam String appId, @RequestParam String platformChannel){
    return payChannelService.queryAppBindPlatformChannel(appId,platformChannel);
}
