需求:页面输入团单号,从数据库中查询搬单错误的数据,以excel形式导出。

前端页面放在ts-settle-tools-web项目中,后端查询数据库的部分写在ts-tg-settle中,以API形式提供给ts-settle-tools使用,其实是通过webservice调用的。

public interface TSSettleService {
     /**
     * 查询搬单错误数据
     * @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>


以上即为API部分的关键代码,打包成jar之后就可以在ts-settle-tools中引入使用。

在ts-tg-settle-service中需要配置pigeon服务的地址,其实就是在配置中心注册服务

<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中需要添加对ts-tg-settle-api的依赖。并且需要配置pigeon服务的地址。

    <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前端效果如下

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 = { "团单号", "套餐号", "验券门店", "结算价", "售价", "验券时间", "券号", "打款状态"};
        try {
            HSSFWorkbook workbook = ex.exportExcel(headers, list);
            String filename = "result.xls";
            response.setContentType("application/vnd.ms-excel");
            response.setHeader("Content-disposition", "attachment;filename=" + filename);
            OutputStream ouputStream = response.getOutputStream();
            workbook.write(ouputStream);
            ouputStream.flush();
            ouputStream.close();
        } catch (Exception e) {

        }

    }
}

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++){
