【JSP】如何在jsp中打开pdf文件。

// java代码
public ActionForward getSoaPdf(ActionMapping mapping, ActionForm form,
                               HttpServletRequest request, HttpServletResponse response) throws IOException {

    String path = request.getParameter("path");
    if (IsPdf(path)) {
        response.setContentType("application/pdf");
    } else {
        response.setContentType("application/vnd.ms-excel");
    }
    ServletOutputStream out = null;
    try {
        out = response.getOutputStream();
    } catch (IOException e) {
        e.printStackTrace();
    }
    //加上下面这句则可以在浏览器外打开,或者保存
    //resp.setHeader("Content-disposition", "attachment;filename=sample.pdf");

    File pdf = null;
    BufferedInputStream buf = null;
    try {
        pdf = new File("G:\Soa_Pdf\" + path);
        response.setContentLength((int) pdf.length());
        FileInputStream input = new FileInputStream(pdf);
        buf = new BufferedInputStream(input);
        int readBytes = 0;
        while ((readBytes = buf.read()) != -1) {
            out.write(readBytes);
        }
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        if (out != null) out.close();
        if (buf != null) buf.close();
    }
    return null;
}

// js代码
function openDetailPdf(path, cnTitle, enTitle) {
    art.dialog.open('operatorquery.do?method=getSoaPdf&path=' + path, {
        title: cnTitle + " " + enTitle,
         1100,
        // height: 450,
        height: 580,
        left: '133px',
        top: '10px',
        fixed: true,
        resize: false,
        padding: '5px 5px',
    });
}
