现在就是需要做一个打印功能，我在java程序中写了一个controller,但是现在需要把程序通过japplet放到浏览器中运行，相当于在浏览器中调用我本地的java程序，但是看了许多文章就是搞不好，我现在把我写的打印的小程序发出来，求教大神怎么改
package print.controller;
import java.util.ArrayList;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import Entity.Word;
import tool.SalesTicket2;
import tool.YcPrinter2;
@Controller
public class PrintController {
@RequestMapping(value = "Print2")
public String print2(HttpServletRequest req,Model model) {
String name=req.getParameter("name"); //项目名称
String demand=req.getParameter("demand"); //要求
String replenish=req.getParameter("replenish"); //补充内容
String score=req.getParameter("score"); //待遇
String check=req.getParameter("check"); //检查考核
String login=req.getParameter("login"); //责任人签字
String other=req.getParameter("other"); //其他
List word=new ArrayList();
word.add(new Word(name,demand,replenish,score,check,login,other));
SalesTicket2 stk2=new SalesTicket2(word);
YcPrinter2 p=new YcPrinter2(stk2);
p.printer();
return "yes";
}
}
下面是打印排版的设置

}
这就是把上面的内容加载出来打印
package tool;
import java.awt.print.Book;
import java.awt.print.PageFormat;
import java.awt.print.Paper;
import java.awt.print.PrinterException;
import java.awt.print.PrinterJob;
/**
- 打印对象 -> 实现Printable接口即可调用打印机打印
- 2017年5月23日 */ public class YcPrinter2{ private SalesTicket2 salesTicket;
public YcPrinter2(SalesTicket2 salesTicket){
this.salesTicket=salesTicket;
}
public void printer() {
try { //Book 类提供文档的表示形式，该文档的页面可以使用不同的页面格式和页面 painter
Book book = new Book(); //要打印的文档
//PageFormat类描述要打印的页面大小和方向
PageFormat pf = new PageFormat(); //初始化一个页面打印对象
pf.setOrientation(PageFormat.PORTRAIT); //设置页面打印方向，从上往下，从左往右
//设置打印纸页面信息。通过Paper设置页面的空白边距和可打印区域。必须与实际打印纸张大小相符。
Paper paper = new Paper();
paper.setSize(590,840);// 纸张大小
paper.setImageableArea(72,72,590,840);// A4(595 X 842)设置打印区域，其实0，0应该是72，72，因为A4纸的默认X,Y边距是72
pf.setPaper(paper);
book.append(salesTicket,pf);
PrinterJob job = PrinterJob.getPrinterJob(); //获取打印服务对象
job.setPageable(book); //设置打印类
boolean a=job.printDialog();
if(a){
job.print(); //开始打印
}
} catch (PrinterException e) {
e.printStackTrace();
}
}
}
省略了实体属性的封装
基本就是这了，就是现在要把这个简单打印功能通过japplet放在浏览器中实现功能。不知道有大神教教没.只有200分都给大神。
现在就是不知道怎么把这个java程序放进japplet里面，包括怎么传值，最好是放japplet的浏览器中有一个打印按钮，点击就能把浏览器中的值传进来打印就好了
