1:定义一个实体类
3:用jdbc或hibernate将java对象存入数据库
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。
使用json-lib.jar这个工具\x0d\x0apublic String getJson(Object obj){\x0d\x0a JSONObject json\x0d\x0a json = JSONObject.fromObject(obj)\x0d\x0a return json.toString()\x0d\x0a}\x0d\x0a使用jquery来处理json\x0d\x0a//转换为json数据 datas可以用ajax从后台获取上面getJson中的数据\x0d\x0avar jsonDatas = eval("(" + datas + ")")\x0d\x0a //循环遍历数据\x0d\x0ajQuery.each(jsonDatas, function(item) {\x0d\x0a//循环\x0d\x0a})
