java使用pdf模板生成pdf文件

   在项目中，遇到了一个变态的需求，要我们在后台生成一个pdf文件，格式又很复杂，想了想如果自己手动利用iText绘制一个pdf，不太现实，通过查找资料后，发现了一种方法：

            利用itextpdf+adobe acrobat+pdf模板生成pdf文件

   要实现这个功能，我使用了这一个第三方包了：itextpdf.jar

   还需要adobe acrobat这个软件，主要用来制作PDF模板

   1.使用adobe acrobat的步骤：

    1.1 将word转换成pdf文件，比如说：remark.pdf；
    1.2 右击remark.pdf点击使用adobe acrobat 编辑的按钮；
    1.3 选择准备表单；
    1.4 adobe acrobat 工具会在表格中自动填充一些“文本域”，默认已 “fill_” 开头；
    1.5 你可以修改表单域的名字，选择添加“文本”域，在想要添加的位置添加即可

   2.编译java代码

    2.1编译表单域的名字的javaBean，与adobe acrobat中的表单域的名字一一对应：

public class Ticket {  
	   
    private String growup;  
    private String attainment;  
    private String present;  
    private String late;  
    private String leave;  
    private String sicklate;  
    private String bigbreak;  
    private String hint;  
    private String evaluate;  
    private String bearpalm;  
    private String praise; 
    private String improve;
    private String yinzhang;

    public Ticket() {  
              super();  
    }

	public Ticket(String growup, String attainment, String present, String late, String leave, String sicklate,
			String bigbreak, String hint, String evaluate, String bearpalm, String praise, String improve,
			String yinzhang) {
		super();
		this.growup = growup;
		this.attainment = attainment;
		this.present = present;
		this.late = late;
		this.leave = leave;
		this.sicklate = sicklate;
		this.bigbreak = bigbreak;
		this.hint = hint;
		this.evaluate = evaluate;
		this.bearpalm = bearpalm;
		this.praise = praise;
		this.improve = improve;
		this.yinzhang = yinzhang;
	}

	public String getGrowup() {
		return growup;
	}

	public void setGrowup(String growup) {
		this.growup = growup;
	}

	public String getAttainment() {
		return attainment;
	}

	public void setAttainment(String attainment) {
		this.attainment = attainment;
	}

	public String getPresent() {
		return present;
	}

	public void setPresent(String present) {
		this.present = present;
	}

	public String getLate() {
		return late;
	}

	public void setLate(String late) {
		this.late = late;
	}

	public String getLeave() {
		return leave;
	}

	public void setLeave(String leave) {
		this.leave = leave;
	}

	public String getSicklate() {
		return sicklate;
	}

	public void setSicklate(String sicklate) {
		this.sicklate = sicklate;
	}

	public String getBigbreak() {
		return bigbreak;
	}

	public void setBigbreak(String bigbreak) {
		this.bigbreak = bigbreak;
	}

	public String getHint() {
		return hint;
	}

	public void setHint(String hint) {
		this.hint = hint;
	}

	public String getEvaluate() {
		return evaluate;
	}

	public void setEvaluate(String evaluate) {
		this.evaluate = evaluate;
	}

	public String getBearpalm() {
		return bearpalm;
	}

	public void setBearpalm(String bearpalm) {
		this.bearpalm = bearpalm;
	}

	public String getPraise() {
		return praise;
	}

	public void setPraise(String praise) {
		this.praise = praise;
	}

	public String getImprove() {
		return improve;
	}

	public void setImprove(String improve) {
		this.improve = improve;
	}

	public String getYinzhang() {
		return yinzhang;
	}

	public void setYinzhang(String yinzhang) {
		this.yinzhang = yinzhang;
	}  
}  

             2.2在表单域中绘制表格（这是4行2列的表格）：

import java.util.List;
import com.itextpdf.text.Chunk;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.Element;
import com.itextpdf.text.Font;
import com.itextpdf.text.Phrase;
import com.itextpdf.text.Rectangle;
import com.itextpdf.text.pdf.AcroFields;
import com.itextpdf.text.pdf.BaseFont;
import com.itextpdf.text.pdf.PdfContentByte;
import com.itextpdf.text.pdf.PdfPCell;
import com.itextpdf.text.pdf.PdfPTable;
import com.itextpdf.text.pdf.PdfStamper;

public class InsertExcel {

	public static void insert(PdfStamper ps, AcroFields s) throws DocumentException  
	{  
	List list = s.getFieldPositions("evaluate");  
	Rectangle rect = list.get(0).position;  
	PdfContentByte cb = ps.getOverContent(1);  
	
		PdfPTable table = new PdfPTable(2);  
		float tatalWidth = rect.getRight() - rect.getLeft() - 1;  
		table.setTotalWidth(tatalWidth);  
		  
		float[] widths = { 0.65f, 0.35f};
	   
		 
		for(int i = 0;i < 4;i++){
		    PdfPCell cell1 = new PdfPCell(new Phrase("好"));
	            cell1.setUseBorderPadding(true);
	            cell1.setBorderWidth(0.2f);
	            cell1.setUseAscender(true); 
	            cell1.setVerticalAlignment(cell1.ALIGN_MIDDLE); 
	            cell1.setHorizontalAlignment(cell1.ALIGN_CENTER);
	            table.addCell(cell1);
	     
	           PdfPCell cell2 = new PdfPCell(new Phrase("Cell 2"));
	           cell2.setUseBorderPadding(true);
	           cell2.setBorderWidth(0.2f);
	           cell2.setUseAscender(true); 
	           cell2.setVerticalAlignment(cell2.ALIGN_MIDDLE); 
	           cell2.setHorizontalAlignment(cell2.ALIGN_CENTER);
	           table.addCell(cell2);
		}
	          table.setWidths(widths);
	          table.setTotalWidth(154);
	          table.setLockedWidth(true);
	          table.getDefaultCell().setMinimumHeight(50);
                 table.writeSelectedRows(0, -1, rect.getLeft(), rect.getTop(), cb);  
	}
}

                 2.3在表单域中插入图片：

String imagePath = "E:\\1.png";  
                   
int pageNo = s.getFieldPositions("present").get(0).page;
Rectangle signRect = s.getFieldPositions("present").get(0).position;
float x = signRect.getLeft();
float y = signRect.getBottom();

 // 读图片
Image image = Image.getInstance(imagePath);
 // 获取操作的页面
 PdfContentByte under = ps.getOverContent(pageNo);
 // 根据域的大小缩放图片
 image.scaleToFit(signRect.getWidth(), signRect.getHeight());
  // 添加图片
  image.setAbsolutePosition(x, y);
  under.addImage(image);
