Joda-Time库在EJB中不起作用

标签： java ejb-3.0 jodatime

我想通过在类路径中添加joda-time-2.5.jar来在无状态ejb3.0中使用joda-time-2.5。但它抛出

  

javax.ejb.EJBException：java.lang.RuntimeException：java.lang.NoClassDefFoundError：org / joda / time / ReadablePartial。

为了测试我创建了一个独立的Java应用程序，它运行正常。

在EJB中调用语句：

long days=DateCalculationsWithJoda.daysBetweenUsingJoda(date1,date2);

我的日期计算类：

import java.util.Date;
import org.joda.time.Days;
import org.joda.time.LocalDate;

public class DateCalculationsWithJoda {

    public static long daysBetweenUsingJoda(Date d1, Date d2) { 
        long days=0;
        System.out.println("in side daysBetweenUsingJoda()");
        try {
            days= Days.daysBetween( new LocalDate(d1.getTime()), new LocalDate(d2.getTime())).getDays(); 
        } catch (Exception e) {
            System.out.println("Exception");
            e.printStackTrace();
        }
        return days;
    } 
}

控件未进入daysBetweenUsingJoda()，因为它未在屏幕上打印。

1 个答案:

答案 0 :(得分：0)

我通过在Managed bean而不是EJB上使用Joda-time进行与日期相关的计算来解决它。在EJB模块中它不起作用。我现在不知道原因，但会更新它。

计算两个日期之间的天数的第二个替代解决方案，在EJB中我们可以使用以下代码而不是使用Joda-time：

public static int daysBetween(Calendar day1, Calendar day2){
Calendar dayOne = (Calendar) day1.clone(),
        dayTwo = (Calendar) day2.clone();

if (dayOne.get(Calendar.YEAR) == dayTwo.get(Calendar.YEAR)) {
    return Math.abs(dayOne.get(Calendar.DAY_OF_YEAR) - dayTwo.get(Calendar.DAY_OF_YEAR));
} else {
    if (dayTwo.get(Calendar.YEAR) > dayOne.get(Calendar.YEAR)) {
        //swap them
        Calendar temp = dayOne;
        dayOne = dayTwo;
        dayTwo = temp;
    }
    int extraDays = 0;

    int dayOneOriginalYearDays = dayOne.get(Calendar.DAY_OF_YEAR);

    while (dayOne.get(Calendar.YEAR) > dayTwo.get(Calendar.YEAR)) {
        dayOne.add(Calendar.YEAR, -1);
        // getActualMaximum() important for leap years
        extraDays += dayOne.getActualMaximum(Calendar.DAY_OF_YEAR);
    }

    return extraDays - dayTwo.get(Calendar.DAY_OF_YEAR) + dayOneOriginalYearDays ;
}
}

我正在使用此代码，因为我不想使用java.util.date的getTime（）。 getTime（）将在99％的时间内工作，但特别是如果您使用的是java 6或java 7，则getTime（）将不会处理任何特殊情况，例如时间或时区，闰年或白天节省时间。当日光变化发生时，它将在夏季边界上失败。所以它可能给出意想不到的O / P.
