JSON 从磁盘序列化和反序列化

java的磁盘IO类太多，搞不清楚，先记着。

===============保存json字符串到磁盘=================

FileOutputStream fos = null;;
try {
fos = new FileOutputStream("E:\\Demo\\workspace\\mjjavaworkspace\\test\\b.json");
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

try {
OutputStreamWriter ow = new OutputStreamWriter(fos, "utf-8");
ow.write( battleInfoArray.toString());
ow.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

=============从磁盘恢复json字符串======================================

FileInputStream fis = null; 
try {
fis = new FileInputStream("E:\\Demo\\workspace\\mjjavaworkspace\\test\\b.json");
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

BufferedReader reader = null;
String jsonString = null;
try {
reader = new BufferedReader( new InputStreamReader(fis, "utf-8"));  


jsonString = reader.readLine();

System.out.println( jsonString );


} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}    

JSONTokener jsonToken = new JSONTokener(jsonString);
JSONArray jArray = new JSONArray(jsonToken);

System.out.print(jArray.toString());
