实现生成PDF、数据插入、导出

@RequestMapping(value = "/DM/gwclwxsq/qygl/exportPDF$m=query.service",method =RequestMethod.POST)
public String exportPdf(@RequestBody GwclwxsqBean gwclwxsqBean , HttpServletResponse response) throws UnsupportedEncodingException {
    // 1.指定解析器
    System.setProperty("javax.xml.parsers.DocumentBuilderFactory",
            "com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl");
    String filename="表单.pdf";
    String path="D:/";
    response.setContentType("application/pdf");

            + URLEncoder.encode(filename, "UTF-8"));
    OutputStream os = null;
    PdfStamper ps = null;
    PdfReader reader = null;
    try {
        os = response.getOutputStream();
        // 2 读入pdf表单
        reader = new PdfReader(path+ "/"+filename);
        // 3 根据表单生成一个新的pdf
        ps = new PdfStamper(reader, os);
        // 4 获取pdf表单
        AcroFields form = ps.getAcroFields();
        // 5给表单添加中文字体 这里采用系统字体。不设置的话，中文可能无法显示
        BaseFont bf = BaseFont.createFont("C:/WINDOWS/Fonts/SIMSUN.TTC,1",
                      BaseFont.IDENTITY_H, BaseFont.EMBEDDED);

        // 6查询数据================================================
        Map<String, String> data = new HashMap<String, String>();
              data.put("commitTime", gwclwxsqBean.getCommitTime());

              data.put("remarks", gwclwxsqBean.getRemarks());
         // 7遍历data 给pdf表单表格赋值
        for (String key : data.keySet()) {
            form.setField(key,data.get(key).toString());
        }
        ps.setFormFlattening(true);
        log.info("*******************PDF导出成功***********************");
    } catch (Exception e) {          log.error("*******************PDF导出失败***********************");
        e.printStackTrace();
    } finally {
        try {
            ps.close();
            reader.close();
