Java 填充模板

一时失言乱红尘 2022-08-28 15:55 214阅读 0赞

最近接了个任务，需要对模板进行填充，使用word模板进行填充，尝试后，使用.docx的文档。  
以下是dome：

/**
         * 模板附件上传
         */
        @Override
        @Transactional(rollbackFor = Exception.class)
        public void legalConUploadTemplate(ConBase conBase) {
            /**
             *1.先根据模板参数去法务获取副本的流，获取到后进行填充，然后保存到本地，然后再从本地获取这附件，上传到法务
             */
            String legalId = baseSysVarClient.getValueByCode("conTemplateLegalId");
            //判断是否已生成模板附件
            List<ConLegalFile> conLegalFileList = conLegalFileService.selectByConBaseIdAndName(conBase.getConBaseId(), "conBase");
            for (ConLegalFile file : conLegalFileList){
                this.deletelegalFile(file, conBase.getUpdateUserCode());
            }
            //获取模板信息
            ConTemplateAttach attach = conTemplateAttachService.selectByLegalId(legalId);
    
            JSONObject js = new JSONObject();
            js.put("attachmentId",attach.getAttachmentId());
            js.put("mipAccount",conBase.getCreateUserCode());
            js.put("fileId",attach.getLegalId());
            byte[] legalDownLoad = this.legalDownLoad(js);
            List<ConItemCenter> info = conItemCenterService.getInfo(conBase.getConBaseId());
            InputStream inputStream = ConTemplateCtr.getInstance().print(new ByteArrayInputStream(legalDownLoad), conBase, info);
            //转换成MultipartFile
            MultipartFile multipartFile = null;
            String name = conBase.getConName() + ".docx";
            try {
                multipartFile = new MockMultipartFile(name, name,
                        ContentType.APPLICATION_OCTET_STREAM.toString(), inputStream);
            } catch (IOException e) {
                e.printStackTrace();
            }
            this.legalConUpload(multipartFile,"ContractNeedStamp",
                    "conBase",conBase.getConBaseId().toString(), conBase.getCreateUserCode());
        }

方法入口  
InputStream inputStream = ConTemplateCtr.getInstance().print(new ByteArrayInputStream(legalDownLoad), conBase, info);  
注意这行代码，在这里面进行填充

import com.midea.dmr.common.utils.DateUtils;
    import com.midea.dmr.cont.domain.bean.ConBase;
    import com.midea.dmr.cont.domain.bean.ConItemCenter;
    
    import java.io.InputStream;
    import java.util.*;
    
    public class ConTemplateCtr {
    
        private ConTemplateCtr() {
        }
    
        private static class ConTemplateCtrInstance {
            private static final ConTemplateCtr INSTANCE = new ConTemplateCtr();
        }
    
        public static ConTemplateCtr getInstance() {
            return ConTemplateCtrInstance.INSTANCE;
        }
    
        /**
         * 模板替换
         */
        public InputStream print(InputStream in, ConBase conBase, List<ConItemCenter> info) {
            // 模板全的路径
            //String templatePaht = "D:\\物料制作年度框架协议.docx";
            // 输出位置
            String outPath = "D:\\物料制作年度框架协议3.docx";
            Map<String, Object> paramMap = new HashMap(16);
            // 普通的占位符示例 参数数据结构 {str,str}
            paramMap.put("vendorName", conBase.getVendorName());
            Date effectiveTime = conBase.getEffectiveTime();
            paramMap.put("effectiveYear", DateUtils.getYear(effectiveTime));
            paramMap.put("effectiveMonth", DateUtils.getMonth(effectiveTime));
            paramMap.put("effectiveDay", DateUtils.getDay(effectiveTime));
            Date expirationTime = conBase.getExpirationTime();
            paramMap.put("expirationYear", DateUtils.getYear(expirationTime));
            paramMap.put("expirationMonth", DateUtils.getMonth(expirationTime));
            paramMap.put("expirationDay", DateUtils.getDay(expirationTime));
            paramMap.put("detailedAddress1", conBase.getDetailedAddress1());
            paramMap.put("vendorUserName", conBase.getVendorUserName());
            paramMap.put("vendorMobile", conBase.getVendorMobile());
            paramMap.put("vendorMail", conBase.getVendorMail());
            paramMap.put("operationCenterName", conBase.getOperationCenterName());
            List<List<String>> tbRow = new ArrayList();
            for (int i = 0; i < info.size(); i++) {
                List<String> tbRow1 = new ArrayList();
                ConItemCenter conItemCenter = info.get(i);
                tbRow1.add(conItemCenter.getCostemCode());
                tbRow1.add(conItemCenter.getProductName());
                tbRow1.add(conItemCenter.getMaterialProcessDesc());
                tbRow1.add(conItemCenter.getMaterialSpec());
                tbRow1.add(conItemCenter.getMaterialBulkSize());
                tbRow1.add(conItemCenter.getUomName());
                if (null != conItemCenter.getRealPrice()) {
                    tbRow1.add(String.valueOf(conItemCenter.getRealPrice().setScale(2)));
                }
                tbRow.add(tbRow1);
            }
            //获取参数
            paramMap.put(PoiWordUtils.addRowText + "tb1", tbRow);
            //模板渲染
            return DynWordUtils.process(paramMap, in, outPath);
        }
    
    
    }

这里主要是参数配置  
//模板渲染  
return DynWordUtils.process(paramMap, in, outPath);  
后面的就是方式类
