JTextPane 实现序列化保存图文混合

//注意，这个方法对于图片而言，会保存为静态图片//代码是可以直接调用了的/* //写入序列化文件 WriteOrReadRecordFile worrf = newWriteOrReadRecordFile(你的JTextPane实例 , "2011-5-28" , "10000" , "F://"); worrf.writeToFile(); //读取序列化文件。默认读取第n个文件。 WriteOrReadRecordFile worrf = newWriteOrReadRecordFile(null , "2011-5-28" , "10000" , "F://"); 你的JTextPane实例.setStyledDocument(worrf.readFromFile()); */import java.io.BufferedReader;import java.io.File;import java.io.FileInputStream;import java.io.FileNotFoundException;import java.io.FileOutputStream;import java.io.FileReader;import java.io.FileWriter;import java.io.IOException;import java.io.ObjectInputStream;import java.io.ObjectOutputStream;import javax.swing.JOptionPane;import javax.swing.JTextPane;import javax.swing.text.StyledDocument;public class WriteOrReadRecordFile {// 这个obj，其实对于这个模块就是用来接收SJTextPane的。private JTextPane m_Obj;private String m_Str_Date;private String m_Str_ID;private String m_filePath;public WriteOrReadRecordFile(JTextPane obj, String date, String ID,String filePath) {m_Obj = obj;m_Str_Date = date;m_Str_ID = ID;m_filePath = filePath;}// 用来接收文件的路径(含文件名)。public boolean writeToFile() {StringBuffer sb = new StringBuffer("");int recNum = returnRecNum(sb);if (sb.toString().equals("false")) {return false;} else {try {// 保存序列化的文件名默认为"serial_n.info"ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream(m_filePath + File.separator+ m_Str_Date + File.separator + m_Str_ID+ File.separator + "serial_" + (recNum + 1)+ ".info"));oos.writeObject(m_Obj.getStyledDocument());oos.close();// 表明当前记录个数为recNum+1;writeToRecNum(recNum + 1);} catch (Exception e) {// TODO Auto-generated catch blockJOptionPane.showMessageDialog(null, "保存记录时出错");return false;}} // else endreturn true;}// 用这个返回的Object时，要记得强制转换为序列化前的类型。public StyledDocument readFromFile() {StyledDocument rtnObj;StringBuffer sb = new StringBuffer("");int recNum = returnRecNum(sb);if (sb.toString().equals("false")) {return null;} else {try {ObjectInputStream ois = new ObjectInputStream(new FileInputStream(m_filePath + File.separator+ m_Str_Date + File.separator + m_Str_ID+ File.separator + "serial_" + (recNum)+ ".info"));rtnObj = (StyledDocument) ois.readObject();ois.close();} catch (Exception e) {// TODO Auto-generated catch blockJOptionPane.showMessageDialog(null, "读取记录时出错");return null;}}return rtnObj;}// 返回读取的记录序列化文件的个数的文件。返回个数。// sb这个参数，传进来用于检测方法是否调用出错。sb需要初始化为空，即new StringBuffer("");private int returnRecNum(StringBuffer sb) {int num = 0;File numFile;// 默认这个文件名为RecordNumnumFile = new File(m_filePath + File.separator + m_Str_Date+ File.separator + m_Str_ID + File.separator + "recordNum.txt");if (!numFile.exists()) {try {numFile.getParentFile().mkdirs();numFile.createNewFile();FileWriter fwriter = new FileWriter(numFile);fwriter.write("0");fwriter.close();} catch (Exception e) {// TODO Auto-generated catch blockJOptionPane.showMessageDialog(null, "创建记录文件失败");sb.append(false);}sb.append(true);return 0;} else {try {FileReader fReader = new FileReader(numFile);BufferedReader bReader = new BufferedReader(fReader);num = Integer.valueOf(bReader.readLine());bReader.close();} catch (Exception e) {// TODO: handle exceptionJOptionPane.showMessageDialog(null, "读取记录文件失败");sb.append(false);return 0;}}sb.append(true);return num;}private boolean writeToRecNum(int num) {try {File numFile = new File(m_filePath + File.separator + m_Str_Date+ File.separator + m_Str_ID + File.separator+ "recordNum.txt");FileWriter fwriter = new FileWriter(numFile);fwriter.write(String.valueOf(num));fwriter.close();} catch (Exception e) {// TODO: handle exceptionJOptionPane.showMessageDialog(null, "写入记录个数文件时出错");return false;}return true;}}
