[开发十年，就只剩下这套Java开发体系了 >>> ][Java_ _]  ![hot3.png][]

# 1、创建pdf #

现在word中创建模板：

输出为pdf文件2.pdf。

# 2、java项目引入依赖 #

<dependency>
    	<groupId>com.itextpdf</groupId>
    	<artifactId>itextpdf</artifactId>
    	<version>${itextpdf.version}</version>
    </dependency>

3、java实现

import java.io.File;
    import java.io.FileOutputStream;
    import java.io.OutputStream;
    import java.util.HashMap;
    import java.util.Map;
    
    import org.junit.Test;
    
    import com.itextpdf.text.pdf.AcroFields;
    import com.itextpdf.text.pdf.BaseFont;
    import com.itextpdf.text.pdf.PdfReader;
    import com.itextpdf.text.pdf.PdfStamper;
    
    
    public class TestPdf {
    
    	@Test
    	public void testPdf() {
    		String inputFileName = "E:\\1\\2.pdf";
    		String outputFileName = "E:\\1\\3.pdf";
    		OutputStream os = null;
    		PdfStamper ps = null;
    		PdfReader reader = null;
    		try {
    			os = new FileOutputStream(new File(outputFileName));
    			// 2 读入pdf表单
    			reader = new PdfReader(inputFileName);
    			// 3 根据表单生成一个新的pdf
    			ps = new PdfStamper(reader, os);
    			// 4 获取pdf表单
    			AcroFields form = ps.getAcroFields();
    			// 5给表单添加中文字体 这里采用系统字体。不设置的话，中文可能无法显示
    			// BaseFont bf = BaseFont.createFont("C:/Windows/Fonts/SIMYOU.TTF",
    			// BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
    			// 方法二：使用iTextAsian.jar中的字体
    			// BaseFont baseFont =
    			// BaseFont.createFont("STSong-Light",BaseFont.IDENTITY_H,BaseFont.NOT_EMBEDDED);
    			BaseFont bf = BaseFont.createFont("/SIMYOU.TTF", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
    			form.addSubstitutionFont(bf);
    			// 6查询数据================================================
    			Map<String, Object> data = new HashMap<String, Object>();
    			data.put("question", "你叫什么名字？");
    			data.put("answer", "张三");
    			// 7遍历data 给pdf表单表格赋值
    			for (String key : data.keySet()) {
    				form.setField(key, data.get(key).toString());
    			}
    			ps.setFormFlattening(true);
    			System.out.println("===============PDF导出成功=============");
    		} catch (Exception e) {
    			System.out.println("===============PDF导出失败=============");
    			e.printStackTrace();
    		} finally {
    			try {
    				ps.close();
    				reader.close();
    				os.close();
    			} catch (Exception e) {
    				e.printStackTrace();
    			}
    		}
    	}
    
    }

注意：SIMYOU.TTF放在resources目录下。
