搬單小工具總結

需求：頁面輸入團單號，從數據庫中查詢搬單錯誤的數據，以excel形式導出。

前端頁面放在ts-settle-tools-web項目中，後端查詢數據庫的部分寫在ts-tg-settle中，以API形式提供給ts-settle-tools使用，實際上是經過webservice調用的。

public interface TSSettleService {
     /**
     * 查詢搬單錯誤數據
     * @param dealGroupIds
     * @return
     */
    public List<TSTGSettleDetailDTO> getWrongData(List<Integer> dealGroupIds);
}

public class TSSettleServiceObject implements TSSettleService {
    @Override
    public List<TSTGSettleDetailDTO> getWrongData(List<Integer> dealGroupIds){
        if(dealGroupIds == null || dealGroupIds.size() == 0){
            return null;
        }
        List<TSTGSettleDetailDTO> result =tsSettleDetailDao.getWrongData(dealGroupIds);
        return result;
    }
}

public interface TSSettleDetailDao extends GenericDao {
    @DAOAction(action = DAOActionType.QUERY)
    public List<TSTGSettleDetailDTO> getWrongData(@DAOParam("dealGroupIds") List<Integer> dealGroupIds);
}

    <resultMap id="tstgSettleDetailDTO" class="com.dianping.ts.tg.settle.api.dtos.TSTGSettleDetailDTO">
        <result property="dealGroupId" column="DealGroupID"/>
        <result property="dealId" column="DealID"/>
        <result property="shopId" column="ShopID"/>
        <result property="dealCost" column="DealCost"/>
        <result property="dealPrice" column="DealPrice"/>
        <result property="settleTime" column="SettleTime"/>
        <result property="detailId" column="DetailID"/>
        <result property="status" column="Status"/>
    </resultMap>
    
        <select id="getWrongData" parameterClass="map" resultMap="tstgSettleDetailDTO">
        select t.id ID, t.DealGroupID DealGroupID, t.DealID DealID, t.ShopID ShopID, t.DealCost DealCost, t.DealPrice DealPrice, t.SettleTime SettleTime, t.DetailID DetailID,
        (CASE
        WHEN p.status=5  THEN 1
        ELSE 0
        END) as Status from TS_TGSettleDetail t left join TS_DistributionDetail d
        on d.AccountID=t.AccountID
        left join TS_PayPlan  p on d.PayPlanID=p.id
        where   d.outbizid=t.GroupID and
        t.DealGroupID in
        <iterate property="dealGroupIds" open="(" close=")" conjunction=",">
            #dealGroupIds[]#
        </iterate>
        <![CDATA[
        and t.UpdateTime>'2015-12-01' and d.UpdateTime>'2015-12-01'   and t.SettleType in (1,3) order by t.id ;
         ]]>
    </select>

以上即爲API部分的關鍵代碼，打包成jar以後就能夠在ts-settle-tools中引入使用。

在ts-tg-settle-service中須要配置pigeon服務的地址，其實就是在配置中心註冊服務

<bean id="tsSettleSystemService" class="com.dianping.dpsf.spring.ServiceRegistry" init-method="init" lazy-init="false">
        <property name="port" value="${ts-tg-settle-service.tsSettleService.port}"/>
        <property name="services">
            <map>
                <entry key="http://service.dianping.com/ts/tg/tsSettleService/TSSettleService_1.0.0" value-ref="tsTGSettleService"/>
            </map>
        </property>
    </bean>

---

ts-settle-tools的pom中須要添加對ts-tg-settle-api的依賴。而且須要配置pigeon服務的地址。

    <bean id="tsSettleService" class="com.dianping.dpsf.spring.ProxyBeanFactory" init-method="init">
        <property name="serviceName" value="http://service.dianping.com/ts/tg/tsSettleService/TSSettleService_1.0.0"/>
        <property name="iface" value="com.dianping.ts.tg.settle.api.TSSettleService"/>
        <property name="serialize" value="hessian"/>
        <property name="callMethod" value="sync"/>
        <property name="timeout" value="5000"/>
    </bean>

ts-settle-tools前端效果以下

Controller部分

@RequestMapping("/settle")
@Controller
public class SettleController {

    @Autowired
    private SettleService settleService;

    @RequestMapping("/downloadResult")
    public String downloadResult(){

        return "downloadResult";
    }

    @RequestMapping("/downloadResultAction")
    public void downloadResultAction(@RequestParam String dealGroupIds, HttpServletRequest request, HttpServletResponse response){

//        System.out.println(groupNo);
        List<TSTGSettleDetailDTO> list = settleService.getWrongData(dealGroupIds);
        //List<TSTGSettleDetailDTO> list1 = settleService.getRightData(dealGroupIds);
        //list.addAll(list1);

        System.out.println(list);

        ExportExcel<TSTGSettleDetailDTO> ex = new ExportExcel<TSTGSettleDetailDTO>();
        String[] headers = { "團單號", "套餐號", "驗券門店", "結算價", "售價", "驗券時間", "券號", "打款狀態"};
        try {
            HSSFWorkbook workbook = ex.exportExcel(headers, list);
            String filename = "result.xls";
            response.setContentType("application/vnd.ms-excel");
            response.setHeader("Content-disposition", "p_w_upload;filename=" + filename);
            OutputStream ouputStream = response.getOutputStream();
            workbook.write(ouputStream);
            ouputStream.flush();
            ouputStream.close();
        } catch (Exception e) {
            e.printStackTrace();
        }

    }
}

Service部分

public class SettleServiceImpl implements SettleService {

    @Autowired
    private TSSettleService tsSettleService;

    public List<TSTGSettleDetailDTO> getRightData(String dealGroupIds){
        String[] strs=dealGroupIds.split(",");
        List<Integer> dealGroupIdList = new ArrayList<Integer>();
        for(int i = 0; i < strs.length; i++){
            dealGroupIdList.add(Integer.valueOf(strs[i]));
        }
        List<TSTGSettleDetailDTO> result = tsSettleService.getRightData(dealGroupIdList);
        return result;
    }
}

處理excel部分

public class ExportExcel<T> {
    public HSSFWorkbook exportExcel(Collection<T> dataset) {
        return exportExcel("導出結果", null, dataset);
    }
