怎么访问json格式数据库

　　直接读写文件，再把读出来的文件内容格式化成json，再用JDBC、Mybatis或者其他框架将json数据存入数据库。

假设实体类是这样的：

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;
}

}
有一个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"}
具体操作：

/*

• 取出文件内容，填充对象
  */

public ElectSet findElectSet(String path){
ElectSet electset=new ElectSet();
String sets=ReadFile(path);//获得json文件的内容
JSONObject jo=JSONObject.fromObject(sets);//格式化成json对象
//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;
}
//设置属性，并保存
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;

}
}
//读文件，返回字符串
public String ReadFile(String path){

File file = new File(path);
BufferedReader reader = null;
String laststr = "";
try {
 //System.out.println("以行为单位读取文件内容，一次读一整行：");
 reader = new BufferedReader(new FileReader(file));
 String tempString = null;
 int line = 1;
 //一次读入一行，直到读入null为文件结束
 while ((tempString = reader.readLine()) != null) {
  //显示行号
  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;

}
将获取到的字符串，入库即可。
