Java使用org.json导出Json文件JavaJsonWrite

import java.io.FileOutputStream; import java.io.OutputStreamWriter; import org.json.JSONObject; public class JavaJsonWrite { public static void main(String[] args) throws Exception { JsonWrite(); } public static void JsonWrite() throws Exception { OutputStreamWriter osw = new OutputStreamWriter(new FileOutputStream("E:\\Temp\\exampleWrite.json"), "UTF-8"); JSONObject obj = new JSONObject();// 创建JSONObject对象 obj.put("FLAG", "1"); for (Integer i = 1; i < 4; i++) { JSONObject subObj = new JSONObject();// 创建对象数组里的子对象 subObj.put("Name", "array" + i); subObj.put("String", "小白" + i); obj.accumulate("ARRAYS", subObj); } System.out.println(obj.toString()); osw.write(obj.toString()); osw.flush();// 清空缓冲区，强制输出数据 osw.close();// 关闭输出流 } }
