Answer 1

java将字符串转换成日期，可以使用格式类，实例如下：

1
2
3
4
5
6
7
8
9
10
11
12
13
14

public static Date dateTimeString2Date(String date_str) {
try {
Calendar cal = Calendar.getInstance();//日期类
java.sql.Timestamp timestampnow = new java.sql.Timestamp(cal.getTimeInMillis());//转换成正常的日期格式
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
ParsePosition pos = new ParsePosition(0);
java.util.Date current = formatter.parse(date_str, pos);
timestampnow = new java.sql.Timestamp(current.getTime());
return timestampnow;
}
catch (NullPointerException e) {
return null;
}
}
