java：读取并修改word中的内容并保存。

1.读取word内容

2.修改要修改的内容

3.保存word

public Map readwriteWord(Map<String, String> map,String gcid,String deptid) {
	//查找word模板
        BindContractTemplate bindContractTemplate = new BindContractTemplate();
        bindContractTemplate.setGCId(gcid);
        bindContractTemplate.setDeptId(deptid);
        bindContractTemplate = bindContractTemplateService.get(bindContractTemplate);
	//吧服务器的模板下载到本机中
        String photoUrl = bindContractTemplate.getContractTemplateUrl();
        String fileNames = photoUrl.substring(photoUrl.lastIndexOf("/"));
        String filePath = "/var/xxx/webserver/xxx/contract/";
        boolean flag = saveUrlAs(photoUrl, filePath +fileNames);
        // 读取word模板
        FileInputStream in = null;
        try {
            in = new FileInputStream(new File(filePath + fileNames));
            //in = new FileInputStream(new File("F:\\1495206705005.doc"));
        } catch (FileNotFoundException e1) {
            e1.printStackTrace();
        }
        HWPFDocument hdt = null;
        try {
            hdt = new HWPFDocument(in);
        } catch (IOException e1) {
            e1.printStackTrace();
        }
        Fields fields = hdt.getFields();
        Iterator<Field> it = fields.getFields(FieldsDocumentPart.MAIN)
                .iterator();
        while (it.hasNext()) {
            System.out.println(it.next().getType());
        }
        // 读取word文本内容
        Range range = hdt.getRange();
        // 替换文本内容
        for (Map.Entry<String, String> entry : map.entrySet()) {
            if (entry.getValue() == null) {
                entry.setValue("  ");
            }
            range.replaceText("${" + entry.getKey() + "}", entry.getValue());
//例如：range.replaceText("${辰辰}", entry.getValue());就是用map的value值代替word中的${辰辰} ，${} 作为标识符，可以改成自己需要的字符，
//用于辨别word中需要修改的内容的位置
        }
