我是第一次使用 docx4j Java 库，但很难找到一个好的参考。我需要开始的是一个简单的 Java 类，以在只读模式下对 Word 文档实施保护。我的通讯距离很远，我可以读取保护模式并进行设置。但是在保存 Word 文档时，更改不会写入 Word 文档。
public class Doc4JPOC {
public static void main(String[] args) {
String docName = "/Users/petervannes/Desktop/Unprotected document.docx";
// String docName = "/Users/petervannes/Desktop/Protected document.docx" ;
Doc4JPOC d4j = new Doc4JPOC();
d4j.isProtected(docName);
d4j.protect(docName);
d4j.isProtected(docName);
}
private void protect(String filename) {
try {
WordprocessingMLPackage wordMLPackage = Docx4J.load(new java.io.File(filename));
MainDocumentPart mdp = wordMLPackage.getMainDocumentPart();
Relationship rs = mdp.getRelationshipsPart().getRelationshipByType(Namespaces.SETTINGS);
DocumentSettingsPart dsp = (DocumentSettingsPart) mdp.getRelationshipsPart().getPart(rs);
// Update settings.xml
List<Object> nodes = dsp.getJAXBNodesViaXPath("//w:documentProtection", true);
for (Object obj : nodes) {
CTDocProtect cdtP = ((CTDocProtect) obj);
cdtP.setEnforcement(Boolean.TRUE);
cdtP.setEdit(STDocProtect.READ_ONLY);
}
// Write updated settings.xml to document
wordMLPackage.addTargetPart(dsp);
// wordMLPackage.save(new java.io.File(filename));
Docx4J.save(wordMLPackage, new java.io.File(filename), 0);
System.out.println("Protected document " + filename) ;
} catch (Docx4JException ex) {
Logger.getLogger(Doc4JPOC.class.getName()).log(Level.SEVERE, null, ex);
} catch (JAXBException jex) {
Logger.getLogger(Doc4JPOC.class.getName()).log(Level.SEVERE, null, jex);
}
}
private void isProtected(String filename) {
Boolean isProtectionEnforced = false;
STDocProtect editMode = STDocProtect.NONE;
try {
WordprocessingMLPackage wordMLPackage = Docx4J.load(new java.io.File(filename));
MainDocumentPart mdp = wordMLPackage.getMainDocumentPart();
Relationship rs = mdp.getRelationshipsPart().getRelationshipByType(Namespaces.SETTINGS);
DocumentSettingsPart dsp = (DocumentSettingsPart) mdp.getRelationshipsPart().getPart(rs);
System.out.println("Partname : " + dsp.getPartName());
List<Object> nodes = dsp.getJAXBNodesViaXPath("//w:documentProtection", true);
for (Object obj : nodes) {
CTDocProtect cdtP = ((CTDocProtect) obj);
isProtectionEnforced = cdtP.isEnforcement();
editMode = cdtP.getEdit();
System.out.println("Enforced: " + cdtP.isEnforcement());
System.out.println("Edit: " + cdtP.getEdit());
}
if (isProtectionEnforced) {
System.out.println("Protection is enabled , protection mode is " + editMode.toString());
} else {
System.out.println("Protection is disabled");
}
} catch (Docx4JException ex) {
Logger.getLogger(Doc4JPOC.class.getName()).log(Level.SEVERE, null, ex);
} catch (JAXBException jex) {
Logger.getLogger(Doc4JPOC.class.getName()).log(Level.SEVERE, null, jex);
}
}
}
执行此类时，我确实得到以下输出；
Partname : /word/settings.xml
Protection is disabled
Protected document /Users/petervannes/Desktop/Unprotected document.docx
Partname : /word/settings.xml
Protection is disabled
所以我怀疑我没有在保护方法中正确更新 WordprocessingMLPackage 或 DocumentSettingsPart，但目前不知道哪里出错了。
