Java 类型转换工具类(持续更新)

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) {

   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]
