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) {
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;
}
}处理excel部分
public class ExportExcel<T> {
public HSSFWorkbook exportExcel(Collection<T> dataset) {
return exportExcel("导出结果", null, dataset);
}

// 生成一个表格
HSSFSheet sheet = workbook.createSheet(title);
// 设置表格默认列宽度为18个字节
sheet.setDefaultColumnWidth((short) 18);
// 生成一个样式
HSSFCellStyle style = workbook.createCellStyle();
// 设置这些样式
style.setFillForegroundColor(HSSFColor.WHITE.index);
style.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);
style.setBorderBottom(HSSFCellStyle.BORDER_THIN);
style.setBorderLeft(HSSFCellStyle.BORDER_THIN);
style.setBorderRight(HSSFCellStyle.BORDER_THIN);
style.setBorderTop(HSSFCellStyle.BORDER_THIN);
style.setAlignment(HSSFCellStyle.ALIGN_CENTER);
// 生成一个字体
HSSFFont font = workbook.createFont();
// font.setColor(HSSFColor.VIOLET.index);
font.setFontHeightInPoints((short) 12);
font.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);
// 把字体应用到当前的样式
style.setFont(font);
// 生成并设置另一个样式
HSSFCellStyle style2 = workbook.createCellStyle();

// 把字体应用到当前的样式
style2.setFont(font2);
// 产生表格标题行
HSSFRow row = sheet.createRow(0);
for (short i = 0; i < headers.length; i++) {
HSSFCell cell = row.createCell(i);
cell.setCellStyle(style);
HSSFRichTextString text = new HSSFRichTextString(headers[i]);

+ fieldName.substring(1);
try {

new Class[] {});
Object value = getMethod.invoke(t, new Object[] {});
// 判断值的类型后进行强制类型转换
if(fieldName.equals("dealCost") || fieldName.equals("dealPrice")){
