jsp操作xml项目实例下载，xml保存数据信息。向xml文件添加书本信息。jsp结合javabean操作xml介绍：
BookDirectory.java源码：
package com.cn.jspxml;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Properties;
public class BookDirectory {
private static Properties properties;
private static BookDirectory bookDirectory = null;
private static final String file = “”;
private BookDirectory() throws Exception {
properties = null;
java.io.InputStream input = this.getClass().getClassLoader()
.getResourceAsStream(file);
if (input != null) {
try {
properties = new Properties();
properties.load(input);
input.close();
} catch (IOException e) {
properties = null;
e.printStackTrace();
throw new Exception();
} finally {
input = null;
}
} else {
throw new Exception();
}
}
public static BookDirectory getInstance() throws Exception {
if (null == bookDirectory) {
bookDirectory = new BookDirectory();
}
return bookDirectory;
}
public void setFile(String name, String filename) throws Exception {
try {
properties.put(name, filename);
String o = this.getClass().getClassLoader().getResource(file)
.getFile();
properties.store(new FileOutputStream(o), “”);
} catch (IOException e) {
throw new Exception();
}
}
public String getFileName(String note){
String name = null;
if(!properties.isEmpty()) {
name = properties.getProperty(note);
}
return name;
}
public int getSize(){
return properties.size();
}
}
BookInfo.java源码：
package com.cn.jspxml;
public class BookInfo {
private String name = null;
private String filename = null;
public BookInfo(String note,String name){
this.name = note;
this.filename = name;
}
public String getAname() {
return name;
}
public void setAname(String name) {
this.name = name;
}
public String getFilename() {
return filename;
}
public void setFilename(String filename) {
this.filename = filename;
}
}
