四、相关配置类

方式一：

使用 Adobe Acrobat DC 制作 pdf 模版，根据制作 pdf 模板生成 pdf 使用到的类

1. 模版配置

import org.springframework.core.io.ClassPathResource;import java.io.IOException;
import java.io.InputStream;
import java.util.HashMap;
import java.util.Map;public class PdfTemplate {/*** pdf 名称*/private String title;/*** pdf 模板*/private InputStream template;/*** 需要填入 pdf 文件中的数据*/private Map<String, PdfData> values;/*** 用于获取 pdf 文件中某些字段的位置信息*/private Map<String, Position> positions;public PdfTemplate() {}public PdfTemplate(String title, InputStream template) {this.title = title;this.template = template;}public PdfTemplate(String title, String templatePath) {this.title = title;try {this.template  = new ClassPathResource(templatePath).getInputStream();} catch (IOException e) {throw new RuntimeException(e);}}public PdfTemplate addValue(String key,PdfData value){if(this.values == null){this.values = new HashMap<>();}this.values.put(key,value);return this;}public PdfTemplate addPositions(String key,Position value){if(this.positions == null){this.positions = new HashMap<>();}this.positions.put(key,value);return this;}public String getTitle() {return title;}public void setTitle(String title) {this.title = title;}public InputStream getTemplate() {return template;}public void setTemplate(InputStream template) {this.template = template;}public Map<String, PdfData> getValues() {return values;}public void setValues(Map<String, PdfData> values) {this.values = values;}public Map<String, Position> getPositions() {return positions;}public void setPositions(Map<String, Position> positions) {this.positions = positions;}
}

2. 数据信息类

import com.itextpdf.text.Image;
import com.kuroshiro.pdf.enums.DataType;
import com.kuroshiro.pdf.enums.TextAttr;import java.util.HashMap;
import java.util.Map;public class PdfData {private DataType type = DataType.TEXT;/*** pdf 对应 key 需要填入的值*/private String value;/*** pdf 对应 key 需要填入的值*/private Image image;/*** 设置字体样式。有效的属性名称是：* textfont - 设置文本字体。该条目的值是一个 BaseFont。* textcolor - 设置文本颜色。该条目的值是一个 BaseColor。* textsize - 设置文本大小。该表项的值为 Float 类型。* bgcolor - 设置背景颜色。该条目的值是一个 BaseColor。如果为null则删除背景。* bordercolor - 设置边框颜色。该条目的值是一个 BaseColor。如果为null则删除边框。*/private Map<TextAttr, Object> textStyles;public PdfData(String value) {this.value = value;}public PdfData(Image image) {this.type = DataType.IMAGE;this.image = image;}public PdfData addTextStyle(TextAttr key,Object value){if(this.textStyles == null){this.textStyles = new HashMap<>();}this.textStyles.put(key,value);return this;}public String getValue() {return value;}public void setValue(String value) {this.value = value;}public DataType getType() {return type;}public void setType(DataType type) {this.type = type;}public Image getImage() {return image;}public void setImage(Image image) {this.image = image;}public Map<TextAttr, Object> getTextStyles() {return textStyles;}public void setTextStyles(Map<TextAttr, Object> textStyles) {this.textStyles = textStyles;}
}

3. 位置信息类

import java.math.BigDecimal;
import java.util.Objects;public class Position {private BigDecimal page;private BigDecimal positionX;private BigDecimal positionY;public Position() {}public Position(BigDecimal page, BigDecimal positionX, BigDecimal positionY) {this.page = page;this.positionX = positionX;this.positionY = positionY;}public Position(int page, int positionX, int positionY) {this.page = BigDecimal.valueOf((long)page);this.positionX = BigDecimal.valueOf((long)positionX);this.positionY = BigDecimal.valueOf((long)positionY);}public boolean equals(Object o) {if (this == o) {return true;} else if (o != null && this.getClass() == o.getClass()) {Position postion = (Position)o;return Objects.equals(this.page.intValue(), postion.page.intValue()) && Objects.equals(this.positionX.intValue(), postion.positionX.intValue()) && Objects.equals(this.positionY.intValue(), postion.positionY.intValue());} else {return false;}}public int hashCode() {return Objects.hash(new Object[]{this.page, this.positionX, this.positionY});}public BigDecimal getPage() {return page;}public void setPage(BigDecimal page) {this.page = page;}public BigDecimal getPositionX() {return positionX;}public void setPositionX(BigDecimal positionX) {this.positionX = positionX;}public BigDecimal getPositionY() {return positionY;}public void setPositionY(BigDecimal positionY) {this.positionY = positionY;}
}

方式二：

创建简单的 table 形式的 pdf

1. Table 配置

import java.util.ArrayList;
import java.util.List;public class PdfTable {/*** 标题*/private String title;/*** 标题字体大小*/private Float fontSize = 21.0F;/*** table 列数*/private int columns = 1;/*** table cell 信息*/private List<PdfTableCell> cells;/*** 标题是否需要边框*/private boolean haveBorder = false;/*** 列宽比例*/private float[] columnWidths;public PdfTable(String title) {this.title = title;}public PdfTable(String title, boolean haveBorder) {this.title = title;this.haveBorder = haveBorder;}public PdfTable(String title,int columns) {this.title = title;this.columns = columns<1?1:columns;}public PdfTable(String title,int columns, boolean haveBorder) {this.title = title;this.columns = columns<1?1:columns;this.haveBorder = haveBorder;}public PdfTable(String title, Float fontSize, int columns) {this.title = title;this.fontSize = fontSize;this.columns = columns<1?1:columns;}public PdfTable(String title, Float fontSize, int columns, boolean haveBorder) {this.title = title;this.fontSize = fontSize;this.columns = columns<1?1:columns;this.haveBorder = haveBorder;}public PdfTable addCell(PdfTableCell cell){if(cells == null){cells = new ArrayList(){{add(cell);}};}else{cells.add(cell);}return this;}public String getTitle() {return title;}public void setTitle(String title) {this.title = title;}public Float getFontSize() {return fontSize;}public void setFontSize(Float fontSize) {this.fontSize = fontSize;}public int getColumns() {return columns;}public void setColumns(int columns) {this.columns = columns;}public List<PdfTableCell> getCells() {return cells;}public void setCells(List<PdfTableCell> cells) {this.cells = cells;}public boolean isHaveBorder() {return haveBorder;}public void setHaveBorder(boolean haveBorder) {this.haveBorder = haveBorder;}public float[] getColumnWidths() {return columnWidths;}public void setColumnWidths(float[] columnWidths) {this.columnWidths = columnWidths;}
}

2. Cell 配置

import com.itextpdf.text.Image;
import com.kuroshiro.pdf.enums.CellAlign;
import com.kuroshiro.pdf.enums.DataType;public class PdfTableCell {private DataType type;private Image image;private String info;private Float fontSize = 16.0F;private CellAlign horizontalAlign = CellAlign.CENTER;private CellAlign verticalAlign = CellAlign.MIDDLE;private int colspan = 1;private boolean haveBorder = true;public PdfTableCell(String info) {this.type = DataType.TEXT;this.info = info;}public PdfTableCell(String info,Float fontSize) {this.type = DataType.TEXT;;this.info = info;this.fontSize = fontSize;}public PdfTableCell(String info,int colspan) {this.type = DataType.TEXT;this.info = info;this.colspan = colspan<1?1:colspan;}public PdfTableCell(String info,int colspan,Float fontSize) {this.type = DataType.TEXT;;this.info = info;this.fontSize = fontSize;this.colspan = colspan<1?1:colspan;}public PdfTableCell(String info,int colspan,boolean haveBorder,Float fontSize, CellAlign horizontalAlign, CellAlign verticalAlign) {this.type = DataType.TEXT;;this.info = info;this.fontSize = fontSize==null?16F:fontSize;this.horizontalAlign = horizontalAlign==null?CellAlign.CENTER:horizontalAlign;this.verticalAlign = verticalAlign==null?CellAlign.MIDDLE:verticalAlign;this.colspan = colspan<1?1:colspan;this.haveBorder = haveBorder;}public PdfTableCell(Image image) {this.type = DataType.IMAGE;this.image = image;}public PdfTableCell(Image image,int colspan) {this.type = DataType.IMAGE;this.image = image;this.colspan = colspan<1?1:colspan;}public PdfTableCell(Image image,int colspan,boolean haveBorder) {this.type = DataType.IMAGE;this.image = image;this.colspan = colspan<1?1:colspan;this.haveBorder = haveBorder;}public Float getFontSize() {return fontSize;}public void setFontSize(Float fontSize) {this.fontSize = fontSize;}public DataType getType() {return type;}public void setType(DataType type) {this.type = type;}public Image getImage() {return image;}public void setImage(Image image) {this.image = image;}public String getInfo() {return info;}public void setInfo(String info) {this.info = info;}public CellAlign getHorizontalAlign() {return horizontalAlign;}public void setHorizontalAlign(CellAlign horizontalAlign) {this.horizontalAlign = horizontalAlign;}public CellAlign getVerticalAlign() {return verticalAlign;}public void setVerticalAlign(CellAlign verticalAlign) {this.verticalAlign = verticalAlign;}public int getColspan() {return colspan;}public void setColspan(int colspan) {this.colspan = colspan;}public boolean isHaveBorder() {return haveBorder;}public void setHaveBorder(boolean haveBorder) {this.haveBorder = haveBorder;}
}

六、测试

public class PdfTest {public static void main(String[] args) throws Exception {pdfTemplate();pdfTable();}public static void pdfTemplate() throws Exception {List<PdfTemplate> list = new ArrayList<>();for (int i = 0; i < 3; i++) {PdfTemplate pdfTemplate = new PdfTemplate("测试","/pdfs/xxk.pdf");pdfTemplate.addValue("cyjgmc",new PdfData("从业机构"+i)).addValue("jgmc",new PdfData("从业机构1111"+i)).addValue("name",new PdfData("张三"+i)).addValue("xxklx",(new PdfData("经纪人")).addTextStyle(TextAttr.TEXTCOLOR, BaseColor.RED)).addValue("xxkh",new PdfData("18313226955")).addValue("xxkyxq",new PdfData("2026-12-18 止+i")).addValue("zjz",new PdfData(Image.getInstance("E:\\zjz.jpg"))).addValue("xxkyxq",new PdfData("2026-12-18 止+i"));String content = "http://sys.yn-yf.cn/fdcjj/wx/ryxx/12345";ByteArrayOutputStream outStream = new ByteArrayOutputStream();Resource resource = new cn.hutool.core.io.resource.ClassPathResource("/static/img/15620371964200.png");QRCodeUtil.encode(content,resource.getUrl().getPath(),outStream,true);pdfTemplate.addValue("qrcode", new PdfData(Image.getInstance(outStream.toByteArray())));list.add(pdfTemplate);}PDFUtils.createPdfByTemplates(list,new FileOutputStream("E:\\xxk1.pdf"));}public static void pdfTable() throws Exception {PdfTable pdfTable = new PdfTable("员工信息表",4);pdfTable.setColumnWidths(new float[]{1.0f,2.0f,1.0f,2.0f});// 添加文本单元格pdfTable.addCell(new PdfTableCell( "姓名")).addCell(new PdfTableCell( "测试测试2222")).addCell(new PdfTableCell( "电话")).addCell(new PdfTableCell( "15912153741")).addCell(new PdfTableCell( "地址")).addCell(new PdfTableCell( "15912153741",3)).addCell(new PdfTableCell(Image.getInstance("E:\\zjz.jpg"),3)).addCell(new PdfTableCell( "")).addCell(new PdfTableCell("郑重申明：谨此保证，本表所填报内容及所附证明材料真实、完整",4,false,11.0F, CellAlign.RIGHT,CellAlign.MIDDLE));// 生成 PDF 到文件try (OutputStream os = new FileOutputStream("E:\\xxk2.pdf")) {PDFUtils.createSimpleTablePDF(pdfTable, os);}}
}

结果
