这是html form.now我想使用jasper reports.i使用ireport设计器5.6.0获取用户输入pdf报告。我应该使用的库是什么以及我应该怎样做才能获得report.i我只使用jsp servlet用于Web应用程序而没有任何frameworks.thanks。
答案 0 :(得分：1)
在这里，我找到了答案的人。感谢您的回复。 首先，我将向您展示文件夹结构。
首先，您必须将上面显示的库添加到您的应用程序中。 然后这是jsp文件代码。

正如您在文件夹结构中看到的那样，您必须制作pojo类。 这是UserDetails.java pojo类。
public class UserDetails {
private String firstname;
private String lastname;
private String email;
private String phonenumber;
private String nic;
/**
* @return the firstname
*/
public String getFirstname() {
return firstname;
}
/**
* @param firstname the firstname to set
*/
public void setFirstname(String firstname) {
this.firstname = firstname;
}
/**
* @return the lastname
*/
public String getLastname() {
return lastname;
}
/**
* @param lastname the lastname to set
*/
public void setLastname(String lastname) {
this.lastname = lastname;
}
/**
* @return the email
*/
public String getEmail() {
return email;
}
/**
* @param email the email to set
*/
public void setEmail(String email) {
this.email = email;
}
/**
* @return the phonenumber
*/
public String getPhonenumber() {
return phonenumber;
}
/**
* @param phonenumber the phonenumber to set
*/
public void setPhonenumber(String phonenumber) {
this.phonenumber = phonenumber;
}
/**
* @return the nic
*/
public String getNic() {
return nic;
}
/**
* @param nic the nic to set
*/
public void setNic(String nic) {
this.nic = nic;
}
}
现在创建简单的pojo类后，你必须创建控制器类。如文件夹结构中所示，report.controller包中包含控制器类GetUserData.java servlet文件。
这是GetUserData.java servlet文件代码。
public class GetUserData extends HttpServlet {
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException, JRException {
//response.setContentType("application/pdf");
//PrintWriter out = response.getWriter();
String firstname = request.getParameter("firstname");
String lastname = request.getParameter("lastname");
String email = request.getParameter("email");
String phonenumber = request.getParameter("phonenumber");
String nic = request.getParameter("nic");
HashMap parametermap = new HashMap();
parametermap.put("firstname", firstname);
parametermap.put("lastname", lastname);
parametermap.put("email", email);
parametermap.put("phonenumber", phonenumber);
parametermap.put("nic", nic);
GenerateReport generatereportinstance = new GenerateReport();
byte[] outputarray = generatereportinstance.GenerateReport(request.getServletContext(),parametermap);
OutputStream outStream = response.getOutputStream();
response.setHeader("Content-Disposition", "filename=UserDetailsReport.pdf");
response.setContentType("application/pdf");
response.setContentLength(outputarray.length);
outStream.write(outputarray, 0, outputarray.length);
}
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
try {
processRequest(request, response);
} catch (JRException ex) {
Logger.getLogger(GetUserData.class.getName()).log(Level.SEVERE, null, ex);
}
}
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
try {
processRequest(request, response);
} catch (JRException ex) {
Logger.getLogger(GetUserData.class.getName()).log(Level.SEVERE, null, ex);
}
}
现在最后一个编码部分。在包report.utility包中创建业务逻辑。 这是GenerateReport.java类文件代码。
public class GenerateReport {
JasperPrint jasperPrint = null;
public byte[] GenerateReport(ServletContext servletContext, HashMap parametermap) {
byte[] outputFile = null;
try {
try {
String file = servletContext.getRealPath("/WEB-INF/report/UserDetails.jasper");
System.out.println("Generating PDF Report");
JasperPrint jasperPrint =JasperFillManager.fillReport(file,parametermap,new JREmptyDataSource());
outputFile =JasperExportManager.exportReportToPdf(jasperPrint);
System.out.println("User Details.pdf has been generated!");
} catch (Exception e) {
e.printStackTrace();
}
} catch (Exception e) {
e.printStackTrace();
}
return outputFile;
}
}
现在你要做更多的事情。创建报告是下一个。 我使用 iReport 5.6.0。创建了UserDeatails.jasper报告 使用iReport创建报告的基本结构后， 右键点击报告转到 - ＆gt;属性 - ＆gt;语言（在语言中选择 java ） 其他明智的报告可能会出错。 然后将report.and编译的.jasper文件编译到项目中，如文件夹结构所示。
我将添加jasper报告的图像。
这就是所有人。非常感谢您的回复。
