struts2 X ireport实现PDF下载

1、js端方法调用

<a href="../xx/pdfDownload!exportToPdfReport.action?oid=123" target="_blank"><span>导出PDF</span></a>

2、后端方法

public void exportToPdfReport() throws IOException {
 Map<String, Object> map = Maps.newHashMap();
 // pdf报表查询条件
 map.put("ids", oid);
 // 获取pdf模板文件路径
 String pdfTemplateRealPath = CommonUtil.getPdfxxxx();
 exportToPdf(pdfTemplateRealPath , map, getResponse().getOutputStream());
}

public void exportToPdf(String reportName, Map<String, Object> paramMap, OutputStream outputStream) {
 InputStream inputStream = null;
 HttpServletResponse resp = super.getResponse();
 resp.setCharacterEncoding("utf-8");
 resp.setContentType("application/pdf");
 resp.setHeader("content-disposition", "attachment;filename=\"xxx.pdf\"");
 try {
   inputSteam = new FileInputStream(reportName);
 } catch () {
 }

 Connection connection = null;
 try {
    connection = dataSource.getConnection();
} catch () {

} 

 try {
   JasperRunManager.runReportToPdfStream(inputStream, outputStream, paramMap, connection);
   outputStream.flush();
   outputStream.close();
} catch () {
} catch () {
} 

}

3、需要引入的jar包

5、pdf报表模板

 

 PS: .jasper文件是编译后的，是在项目中起作用的
