ref和reactive的区别

简介

将项目中用到的类型转换做个记录。

详细代码

@Component
public class TypeUtil {
 // [start]字符串转各种格式

 // 字符串转日期(格式:"yyyyMMdd")
 public static Date StrToDateFirst(String str) {
  DateFormat format = new SimpleDateFormat("yyyyMMdd");
  Date date = null;
  try {
   date = format.parse(str);
  } catch (ParseException e) {
   e.printStackTrace();
  }
  return date;
 }

 // 字符串转日期(格式:"dd/MM/yyyy")
 public static Date StrToDateSecond(String str) {
  DateFormat format = new SimpleDateFormat("dd/MM/yyyy");
  Date date = null;
  try {
   date = format.parse(str);
  } catch (ParseException e) {
   e.printStackTrace();
  }
  return date;
 }

 // 字符串转日期(格式:"yyyy-MM-dd")
 public static Date StrToDateThird(String str) {
  DateFormat format = new SimpleDateFormat("yyyy-MM-dd");
  Date date = null;
  try {
   date = format.parse(str);
  } catch (ParseException e) {
   e.printStackTrace();
  }
  return date;
 }

 // 字符串转日期(格式:"yyyy-MM-dd HH:mm:ss")
 public static Date StrToDateFourth(String str) {
  DateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
  Date date = null;
  try {
   date = format.parse(str);
  } catch (ParseException e) {
   e.printStackTrace();
  }
  return date;
 }

 // 字符串转Integer
 public static Integer StrToInteger(String str) {
  Integer integer = null;
  try {
   integer = Integer.valueOf(str);
  } catch (Exception e) {
   e.printStackTrace();
  }
  return integer;
 }

 // 字符串转Double
 public static Double StrToDouble(String str) {
  Double double1 = 0.00;
  try {
   double1 = Double.parseDouble(str);
  } catch (Exception e) {
   e.printStackTrace();
  }
  return double1;
 }

 // 字符串转时间戳
 public static Timestamp StrToTimeStamp(String str) {
  Timestamp timestamp = null;
  try {
   timestamp = Timestamp.valueOf(str);
  } catch (Exception e) {
   e.printStackTrace();
  }
  return timestamp;
 }

 // 字符串转BigDecimal
 public static BigDecimal StrTiBigdecimal(String str) {
  BigDecimal bigDecimal = null;
  try {
   bigDecimal = new BigDecimal(str);
  } catch (Exception e) {
   e.printStackTrace();
  }
  return bigDecimal;
 }
 // [end]
