我使用JAXB创建文件夹和文件层次结构
我的模特：
@XmlRootElement
public class Root {
@XmlAttribute
private String path;
@XmlElement(name = "dir")
private ArrayList
@XmlElement(name = "file")
private ArrayList rootContentFiles = null;
public void setRootContentDirs(ArrayList
this.rootContentDirs = rootContentDirs;
}
public void setRootContentFiles(ArrayList rootContentFiles) {
this.rootContentFiles = rootContentFiles;
}
public void setPath(String path) {
this.path = path;
}
}
public class Dir {
@XmlAttribute
private String name;
@XmlElement(name = "dir")
private ArrayList dirs = null;
@XmlElement(name = "file")
private ArrayList files = null;
public void setName(String name) {
this.name = name;
}
public void setDirs(ArrayList dirs) {
this.dirs = dirs;
}
public void setFiles(ArrayList files) {
this.files = files;
}
}
public class FileObj{
@XmlAttribute
private String name;
@XmlAttribute
private long size;
@XmlAttribute
private String type;
public void setName(String name) {
this.name = name;
}
public void setSize(long size) {
this.size = size;
}
public void setType(String type) {
this.type = type;
}
}
我想制作目录和文件树：
public class XmlByJaxb extends Generator {
private static final String JAXB_XML = "./jaxb.xml";
private static Root root = null;
@Override
public void output() throws IOException {
JAXBContext context = null;
Marshaller m = null;
try {
context = JAXBContext.newInstance(Root.class, Dir.class, FileObj.class);
m = context.createMarshaller();
m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
m.marshal(root, new File(JAXB_XML));
} catch (JAXBException e) {
}
}
@Override
public void run() {
ArrayList rootFiles = addFiles(dir);
ArrayList
root = new Root();
root.setPath(dir.getPath());
root.setRootContentFiles(rootFiles);
root.setRootContentDirs(rootDirs);
/.../
}
但是我在生成的xml中有一个奇怪的“ xsi：type”和“ xmlns：xsi”：
/.../
所以我的问题是：这是什么意思，如何删除？
