Jasper用中文报道pdf

Question

在我的项目中，我使用jasper报告来获取pdf和excel。当我从数据库导出英文字符时，报告工作正常，但是当我导出中文字符时，报告适用于excel，但pdf中没有显示中文字符。

我为adobe reader 11安装了简体中文和繁体中文的语言包。

这是调用reportfinal.build（）函数的代码，用于构建报告：

 public String OrgReport(){
        List<String> a = new ArrayList<String>();
        a.add("ORG_NAME");
        a.add("ORG_CODE");
        a.add("REGISTRATION_NO");
        a.add("CONTACT_PERSON");
        a.add("EMAIL_OFC");
        a.add("PHONE_NO_OFC");
        a.add("AI_STATUS_ID");

        List<String> colname = new ArrayList<String>();
        colname.add("Organisation Name");
        colname.add("Organisation Code");
        colname.add("Registration No");
        colname.add("Contact Person");
        colname.add("Email");
        colname.add("Contact No");
        colname.add("Status");



        String tabname="ORG_MASTER_MSYS";
        List<Map<String,?>> OrgData= new ArrayList<Map<String,?>>();
        OrgData=organisationManager.getOrgdata(a,tabname);


    List<ColumnValuemMapperDTO> columnValuemMapperDTOlist;
        columnValuemMapperDTOlist=new ArrayList<ColumnValuemMapperDTO>();
         for(int i =0;i<OrgData.size();i++){
             ColumnValuemMapperDTO ob=new ColumnValuemMapperDTO();
             ob.setColumnValueMap(OrgData.get(i));
             columnValuemMapperDTOlist.add(ob);
         }
        UserDTO userDto = (UserDTO) getServletRequest().getSession()
                .getAttribute("LoginVO");
        String Username1 = "";

         Username = Username1.concat("" + userDto.getFname() + " "
                    + userDto.getLname() + "");

        AdhocCustomizerReportWeb reportfinal = new AdhocCustomizerReportWeb();

        String reportName = "Organisation_Master_Grid";
        String Layout = "land";
        String beforedate = "Notdefined";
        String currentdate = "Notdefined";

        String reportHead = "Organisation Master";
        String filepath;
        try {


            reportfinal.build( colname, columnValuemMapperDTOlist,
                    reportName, formatId, reportHead, Layout, Username,
                    beforedate, currentdate);
            filepath = reportfinal.getFilepath();
            int index = filepath.lastIndexOf("\\");

            filename = filepath.substring(index + 1);
         fileInputStream = new FileInputStream(new File(filepath));
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            return ERROR;
        }

     return SUCCESS;

接下来我还提供了构建函数的代码： -
