`org.apache.xmlbeans.XmlOptions.setEntityExpansionLimit(int)` 方法是用来设置 XML 文档中实体扩展的限制。实体扩展是指在 XML 文档中使用实体引用来代替实际的文本内容。该方法可以通过传入一个整数值来设置限制,防止实体扩展导致的资源消耗过大或安全风险。具体限制的值可以根据需求进行调整,一般情况下建议设置一个合理的较小值以确保安全。

Java在word指定页数开头插入一张图片
可以使用Apache POI库来实现在Word指定页数开头插入一张图片。具体的实现方法可以参考以下代码:

try {
String docxPath = "D:\\temp\\test.docx";
int pageNumber = 2;
String picPath = "D:\\temp\\test.png";
//打开docx文件
FileInputStream fis = new FileInputStream(docxPath);
XWPFDocument document = new XWPFDocument(fis);
fis.close();
//获取目标页面的段落
XWPFParagraph paragraph = document.getParagraphs().stream()
.filter(p -> document.getPosOfParagraph(p) >= document.getDocument().getBody().getSectPr().getPgSz().getH().intValue()*pageNumber)
.findFirst()
.orElse(null);
if(paragraph == null) {
System.out.println("未找到指定页面。");
return;
}
//在目标段落前面插入一张图片
XmlCursor cursor = paragraph.getCTP().newCursor();
cursor.toPrevSibling();
XWPFParagraph newParagraph = document.insertNewParagraph(cursor);
XWPFRun newRun = newParagraph.createRun();
newRun.addCarriageReturn();
//图片嵌入段落
String id = document.addPictureData(new FileInputStream(picPath), XWPFDocument.PICTURE_TYPE_PNG);
XWPFPicture picture = newRun.addPicture(new FileInputStream(picPath), XWPFDocument.PICTURE_TYPE_PNG, "abcdef", Units.toEMU(180), Units.toEMU(100));
//设置图片位置(水平和垂直居中)
picture.getCTPicture().getSpPr().getLn().setNoFill(true); //去掉边框
CTPicture ctPic = picture.getCTPicture();
CTTransform2D ctTransform2D = CTTransform2D.Factory.newInstance();
ctTransform2D.setRot(0);
CTPoint2D ctPoint2D = ctTransform2D.addNewOff();
ctPoint2D.setX(Units.toEMU(400)); //横坐标
ctPoint2D.setY(Units.toEMU(200)); //纵坐标
ctPic.getSpPr().getXfrm().setOff(ctTransform2D);
CTAnchor ctAnchor = ctPic.getAnchor();
ctAnchor.setSimplePos2(false);
ctAnchor.setX(0);
ctAnchor.setY(0);
CTMarker ctMarker = ctAnchor.addNewFrom();
ctMarker.setCol(0);
ctMarker.setColOff(0);
ctMarker.setRow(0);
ctMarker.setRowOff(0);
ctMarker = ctAnchor.addNewTo();
ctMarker.setCol(0);
ctMarker.setColOff(0);
ctMarker.setRow(0);
ctMarker.setRowOff(0);
//保存docx文件
FileOutputStream fos = new FileOutputStream(docxPath);
document.write(fos);
fos.close();
System.out.println("图片插入成功!");
} catch (Exception e) {
e.printStackTrace();
}
}
}
```
在这段代码中,首先打开docx文件,并根据指定的页数获取目标段落。然后,在目标段落前插入一张图片,并设置该图片的位置为垂直和水平居中。最后保存docx文件即可。
java填充wordxml格式,java xml转成word文档格式
您可以使用Apache POI库来填充Word XML格式的模板并生成Word文档。以下是一个简单的示例代码:
```java
import java.io.FileInputStream;
import java.io.FileOutputStream;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;
import org.apache.xmlbeans.XmlCursor;
import org.apache.xmlbeans.XmlObject;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTBody;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTDocument1;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTMarkupRange;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTNumbering;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTP;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTR;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTSimpleField;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTSimpleField.Lock;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTStyles;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.STOnOff;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.STSimpleField;
public class WordXMLGenerator {
public static void main(String[] args) throws Exception {
// Load the Word XML template
XWPFDocument template = new XWPFDocument(
new FileInputStream("template.docx"));
// Get the main document part
CTDocument1 doc = template.getDocument();
// Get the body of the document
CTBody body = doc.getBody();
// Traverse the XML structure and find the placeholder
XmlObject[] objects = body.selectPath(
"declare namespace w='http://schemas.openxmlformats.org/wordprocessingml/2006/main' " +
".//w:t[.='<<MY_PLACEHOLDER>>']");
// Replace the placeholder with the desired text
if (objects.length > 0) {
XmlCursor cursor = objects[0].newCursor();
cursor.toParent();
CTP paragraph = (CTP) cursor.getObject();
cursor.dispose();
XWPFParagraph xwpfParagraph = new XWPFParagraph(paragraph, template);
XWPFRun run = xwpfParagraph.createRun();
run.setText("Hello, World!");
// Remove the placeholder text from the document
CTR ctr = paragraph.getRArray(0);
ctr.setTArray(0, "");
}
// Save the modified document to a file
template.write(new FileOutputStream("output.docx"));
template.close();
}
}
```
另外,如果您有一个现有的XML文件,您可以使用Apache POI库将其转换为Word文档。以下是示例代码:
```java
import java.io.FileInputStream;
import java.io.FileOutputStream;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;
import org.w3c.dom.Document;
import org.w3c.dom.NodeList;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
public class XMLToWord {
public static void main(String[] args) throws Exception {
// Load the XML file
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document xml = builder.parse(new FileInputStream("input.xml"));
// Create a new Word document
XWPFDocument document = new XWPFDocument();
// Traverse the XML structure and add the text to the document
NodeList nodes = xml.getElementsByTagName("text");
for (int i = 0; i < nodes.getLength(); i++) {
String text = nodes.item(i).getTextContent();
XWPFParagraph paragraph = document.createParagraph();
XWPFRun run = paragraph.createRun();
run.setText(text);
}
// Save the Word document to a file
document.write(new FileOutputStream("output.docx"));
document.close();
}
}
```
