我需要创建一个PDF来保存执行状态报告，其中状态将在表结构中。是否可以使用PDFBOX api生成pdf表格式？
以下是一些用于创建新PDF文档的示例代码：
import java.awt.Color;
import java.io.IOException;
import org.apache.pdfbox.exceptions.COSVisitorException;
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.pdmodel.PDPage;
import org.apache.pdfbox.pdmodel.edit.PDPageContentStream;
import org.apache.pdfbox.pdmodel.font.PDFont;
import org.apache.pdfbox.pdmodel.font.PDType1Font;
public class HelloWorld
{
/**
* Constructor.
*/
public HelloWorld()
{
super();
}
public static void main(String[] args) throws IOException, COSVisitorException
{
PDDocument doc = null;
try
{
doc = new PDDocument();
PDPage page = new PDPage();
doc.addPage( page );
PDFont font = PDType1Font.COURIER_BOLD_OBLIQUE;
Color color = Color.blue;
PDPageContentStream contentStream = new PDPageContentStream(doc, page);
contentStream.beginText();
contentStream.setFont( font, 12 );
contentStream.setNonStrokingColor(color);
contentStream.moveTextPositionByAmount( 100, 700 );
contentStream.drawString( "message" );
contentStream.setNonStrokingColor(Color.GREEN);
contentStream.drawString( "Hi" );
contentStream.endText();
contentStream.close();
doc.save( "d:\\abc.pdf" );
}
finally
{
if( doc != null )
{
doc.close();
}
}
}
}
答案 0 :(得分：16)
试试这个：
public static void drawTable(PDPage page, PDPageContentStream contentStream,
float y, float margin,
String[][] content) throws IOException {
final int rows = content.length;
final int cols = content[0].length;
final float rowHeight = 20f;
final float tableWidth = page.getCropBox().getWidth() - margin - margin;
final float tableHeight = rowHeight * rows;
final float colWidth = tableWidth/(float)cols;
final float cellMargin=5f;
//draw the rows
float nexty = y ;
for (int i = 0; i <= rows; i++) {
contentStream.drawLine(margin, nexty, margin+tableWidth, nexty);
nexty-= rowHeight;
}
//draw the columns
float nextx = margin;
for (int i = 0; i <= cols; i++) {
contentStream.drawLine(nextx, y, nextx, y-tableHeight);
nextx += colWidth;
}
//now add the text
contentStream.setFont( PDType1Font.HELVETICA_BOLD , 12 );
float textx = margin+cellMargin;
float texty = y-15;
for(int i = 0; i < content.length; i++){
for(int j = 0 ; j < content[i].length; j++){
String text = content[i][j];
contentStream.beginText();
contentStream.moveTextPositionByAmount(textx,texty);
contentStream.drawString(text);
contentStream.endText();
textx += colWidth;
}
texty-=rowHeight;
textx = margin+cellMargin;
}
}
只需在main函数
public static void main(String[] args) throws IOException, COSVisitorException {
PDDocument doc = new PDDocument();
PDPage page = new PDPage();
doc.addPage( page );
PDPageContentStream contentStream = new PDPageContentStream(doc, page);
String[][] content = {
{"Name"," Time "},
{"HTC","01:25"},
{"Samsung Tab2","05:30"}
} ;
drawTable(page, contentStream, 700, 100, content);
contentStream.close();
doc.save("h:\\test.pdf" );
}

我刚为pdfBOX og github添加了一个简单的包装器。它有一个简单的表支持，您可以将其用作剪切基准。或者如果需要，可以按原样使用该类。 https://github.com/heksemann/HexPDF

我创建了此类，可以在用户文档中构建pdf

{"The origin of labor unions dates back to the eighteenth century and the industrial revolution in Europe. During this time there was a huge surge of new workers into the workplace that needed representation. In the United States history of unions, early workers and trade unions played an important part in the role for independence. Although their physical efforts for the cause of independence were ineffective, the ideas they introduced, such as protection for workers, became part of our American culture."},
{"In the history of America's trade and labor unions, the most famous union remains the American Federation of Labor (AFL), founded in 1886 by Samuel Gompers. At its pinnacle, the AFL had approximately 1.4 million members. The AFL is credited with successfully negotiating wage increases for its members and enhancing workplace safety for all workers."},

For those in the industrial sector, organized labor unions fought for better wages, reasonable hours and safer working conditions. The labor movement led efforts to stop child labor, give health benefits and provide aid to workers who were injured or retired."}
