import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
/**
* String 转Date
*/
public static Date stringToDate(String str){
SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date time =null;
try {
time=sdf.parse(str);
} catch (ParseException e) {
e.printStackTrace();
}
return time;
}

/**
* Date 转String
*/
public static String dateToString(Date date){
SimpleDateFormat sdf =new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
