接之前的PDF转换，需求批量PDF导出压缩包
注意一下依赖版本
<dependency>
<groupId>com.itextpdf</groupId>
<artifactId>itextpdf</artifactId>
<version>5.5.9</version>
</dependency>
<dependency>
<groupId>com.itextpdf</groupId>
<artifactId>itext-asian</artifactId>
<version>5.2.0</version>
</dependency>
<dependency>
<groupId>com.itextpdf.tool</groupId>
<artifactId>xmlworker</artifactId>
<version>5.5.9</version>
</dependency>
itextpdf和xmlworker要保持一致，不然可能会报错
Controller层：
jsp视图的接口：
@RequestMapping(value = "/zyOpenProFinishPrint/{processInstanceId}/{projectId}")
public String zyOpenProFinishPrint(final @PathVariable String processInstanceId, final @PathVariable int projectId,
HttpServletRequest request, HttpServletResponse response,
final Model model) throws BizException {
//通过ID获取项目信息
ZyProjectInfo project = zyProjectInfoService.getZyProjectAmountById(projectId);
//转账信息
ZyProjectEnd qry = new ZyProjectEnd();
qry.setProjectId(new Long(projectId));
ZyProjectEnd vo = zyProjectEndService.getByProjectId(qry);
//收入信息
ZyJSalesContract zyJSalesContract = new ZyJSalesContract();
zyJSalesContract.setConType("0");
zyJSalesContract.setProjectId(new Long(projectId));
List<ZyJSalesContract> zyJSalesContracts = zyJSalesContractService.getListPrint(zyJSalesContract);
//收入信息--合计
BigDecimal totalContractAmount = new BigDecimal(0);//合同金额
BigDecimal finalPriceTaxTotal = new BigDecimal(0);//审定价(含税)
BigDecimal finalPrice = new BigDecimal(0);//审定价(不含税)
BigDecimal sumAmount = new BigDecimal(0);//累计收款

//成本信息
