直接讀寫文件，再把讀出來的文件內容格式化成json，再用JDBC、Mybatis或者其他框架將json數據存入資料庫。
假設實體類是這樣的：
public class ElectSet {
public String xueqi;
public String xuenian;
public String startTime;
public String endTime;
public int menshu;
public String isReadDB;
//{"xueqi":,"xuenian":,"startTime":,"endTime":,"renshu":,"isReadDB":}
public String getXueqi() {
return xueqi;
}
public void setXueqi(String xueqi) {
this.xueqi = xueqi;
}
public String getXuenian() {
return xuenian;
}
public void setXuenian(String xuenian) {
this.xuenian = xuenian;
}
public String getStartTime() {
return startTime;
}
public void setStartTime(String startTime) {
this.startTime = startTime;
}
public String getEndTime() {
return endTime;
}
public void setEndTime(String endTime) {
this.endTime = endTime;
}
public int getMenshu() {
return menshu;
}
public void setMenshu(int menshu) {
this.menshu = menshu;
}
public String getIsReadDB() {
return isReadDB;
}
public void setIsReadDB(String isReadDB) {
this.isReadDB = isReadDB;
}
}
有一個json格式的文件，存的信息如下：
Sets.json:
{"xuenian":"2007-2008","xueqi":"1","startTime":"2009-07-19 08:30","endTime":"2009-07-22 18:00","menshu":"10","isReadDB":"Y"}
具體操作：
/*
* 取出文件內容，填充對象
*/
public ElectSet findElectSet(String path){
ElectSet electset=new ElectSet();
String sets=ReadFile(path);//獲得json文件的內容
JSONObject jo=JSONObject.fromObject(sets);//格式化成json對象
//System.out.println("------------" jo);
//String name = jo.getString("xuenian");
//System.out.println(name);
electset.setXueqi(jo.getString("xueqi"));
electset.setXuenian(jo.getString("xuenian"));
electset.setStartTime(jo.getString("startTime"));
electset.setEndTime(jo.getString("endTime"));
electset.setMenshu(jo.getInt("menshu"));
electset.setIsReadDB(jo.getString("isReadDB"));
return electset;
}
//設置屬性，並保存
public boolean setElect(String path,String sets){
try {
writeFile(path,sets);
return true;
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return false;
}
}
//讀文件，返回字元串
public String ReadFile(String path){
File file = new File(path);
BufferedReader reader = null;
String laststr = "";
try {
//System.out.println("以行為單位讀取文件內容，一次讀一整行：");
reader = new BufferedReader(new FileReader(file));
String tempString = null;
int line = 1;
//一次讀入一行，直到讀入null為文件結束
while ((tempString = reader.readLine()) != null) {
//顯示行號
System.out.println("line " line ": " tempString);
laststr = laststr tempString;
line ;
}
reader.close();
} catch (IOException e) {
e.printStackTrace();
} finally {
if (reader != null) {
try {
reader.close();
} catch (IOException e1) {
}
}
}
return laststr;
}
將獲取到的字元串，入庫即可。
