最近公司新開了一個游戲項目，我負責游戲服務端邏輯的設計與編寫相關的代碼。今天為了把json配置文件的內容存到緩存里寫了個讀取json文件的工具類，雖然比較簡單，還是想先分享一下，我決定之后的幾天里重溫一下java IO和NIO相關的內容。

import java.io.BufferedReader;import java.io.File;import java.io.FileInputStream;import java.io.IOException;import java.io.InputStreamReader;import net.sf.json.JSONArray;public class LoadJsonFile {	public static JSONArray load(String path) {		System.out.PRintln("path" + path);		BufferedReader bufferedReader = null;		JSONArray dataJson = null;		try {			InputStreamReader isr = new InputStreamReader(new FileInputStream(					new File(path)), "UTF-8");			bufferedReader = new BufferedReader(isr);			String lineContent = null;			StringBuffer connBuffer = new StringBuffer();			while ((lineContent = bufferedReader.readLine()) != null) {				connBuffer.append(lineContent);			}			dataJson = JSONArray.fromObject(connBuffer.toString());			bufferedReader.close();		} catch (IOException e) {			e.printStackTrace();		} finally {			try {				if (bufferedReader != null) {					bufferedReader.close();				}			} catch (IOException e) {				e.printStackTrace();			}		}		return dataJson;	}}
