好吧，我将回答我自己的问题。创建插件是正确的方法。
我写了以下插件，它似乎可以工作。
public class PrivateMemberPlugin extends Plugin{ @Override public String getOptionName() { return "Xpm"; } @Override public String getUsage() { return " -Xpm : Change members visibility to private"; } @Override public boolean run(Outline model, Options opt, ErrorHandler errorHandler) throws SAXException { for (ClassOutline co : model.getClasses()) { JDefinedClass jdc = co.implClass; // avoid concurrent modification by copying the fields in a new list List<JFieldVar> fields = new ArrayList<JFieldVar>(jdc.fields().values()); for (JFieldVar field : fields) { // never do something with serialVersionUID if it exists. if (!field.name().equalsIgnoreCase("serialVersionuid")) { // only try to change members that are not private if (field.mods().getValue() != JMod.PRIVATE) { // since there is no way to change the visibilty, remove the field an recreate it jdc.removeField(field); jdc.field(JMod.PRIVATE, field.type(), field.name()); } } } } return true; }}如果需要，请随意使用。
