Jmeter组件BeanShell 取样器调用Java代码处理时间

在测试过程中经常会遇到一些接口中的参数需要进行处理时间格式，比如当前时间、当前日期，当月一号，下个月一号等等，下面我们就使用Jmeter组件BeanShell 取样器调用Java代码进行处理，首先在jmeter的目录D:\apache-jmeter-5.1.1\bin下新建DateUtil.java，如下图：
代码如下：
import java.text.Format;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;

public class DateUtil
{
public static String getdodyTime()
{
Date date=new Date();

    Format f = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

    String todaytime=f.format(date);

    return todaytime;
    
}

public static String getTodyData()
{
    Date date=new Date();

    Format f = new SimpleDateFormat("yyyy-MM-dd");

    String today=f.format(date);

    return today;
}

public static String getTomorrowDate()
{
    Date date=new Date();

    Format f = new SimpleDateFormat("yyyy-MM-dd");

    Calendar c = Calendar.getInstance();

    c.setTime(date);

    c.add(Calendar.DAY_OF_MONTH, 1);// 今天+1天

    Date tomorrow_date = c.getTime();

    String tomorrow=f.format(tomorrow_date);

    return tomorrow;
}

 public static String getYesterdayDate()
{
    Date date=new Date();

    Format f = new SimpleDateFormat("yyyy-MM-dd");

    Calendar c = Calendar.getInstance();

    c.setTime(date);

    c.add(Calendar.DAY_OF_MONTH, -1);// 今天-1天

    Date yesterday_date = c.getTime();

    String yesterday=f.format(yesterday_date);

    return yesterday;
}

public static String getTomorrowTime()
{
    Date date=new Date();

    Format f = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

    Calendar c = Calendar.getInstance();

    c.setTime(date);

    c.add(Calendar.DAY_OF_MONTH, 1);// 今天+1天

    Date tomorrow_date = c.getTime();

    String tomorrowtime=f.format(tomorrow_date);

    return tomorrowtime;
}

public static String getTomorrowTimeSubtract()
{
    Date date=new Date();

    Format g = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

    Calendar e = Calendar.getInstance();

    e.setTime(date);

    e.add(Calendar.DAY_OF_MONTH, -60);// 今天-60天

    Date tomorrow_date_subtract = e.getTime();

    String tomorrowtimesubtract=g.format(tomorrow_date_subtract);

    return tomorrowtimesubtract;
}

public static String getTomorrowTimeSubtractDate()
{
    Date date=new Date();

    Format g = new SimpleDateFormat("yyyy-MM-dd");

    Calendar e = Calendar.getInstance();

    e.setTime(date);

    e.add(Calendar.DAY_OF_MONTH, -60);// 今天-60天

    Date tomorrow_date = e.getTime();

    String tomorrowtimesubtractdate=g.format(tomorrow_date);

    return tomorrowtimesubtractdate;
}

public static String getTomorrowTimeadd()
{
    Date date=new Date();

    Format g = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

    Calendar e = Calendar.getInstance();

    e.setTime(date);

    e.add(Calendar.DAY_OF_MONTH, 10);// 今天+10天

    Date tomorrow_date = e.getTime();

    String tomorrowtimeadd=g.format(tomorrow_date);

    return tomorrowtimeadd;
}

public static String getnowYear()
{
    Date date=new Date();

    Format year = new SimpleDateFormat("yyyy");//当前年

    Calendar e = Calendar.getInstance();

    e.setTime(date);

    Date year_date = e.getTime();

    String nowYear=year.format(year_date );

    return nowYear;
}

public static String getnowMonth()
{
    Date date=new Date();

    Format month = new SimpleDateFormat("MM");//当前月

    Calendar e = Calendar.getInstance();

    e.setTime(date);

    Date month_date = e.getTime();

    String nowMonth=month.format(month_date);

    return nowMonth;
}

public static String getDateMonth()
{
    Date date=new Date();

    Format month_format = new SimpleDateFormat("yyyy-MM-01");

    Calendar cal = Calendar.getInstance();

    cal.setTime(date);

    cal.set(Calendar.DAY_OF_MONTH,0);////本月第一天

    Date month = cal.getTime();

    String month_date=month_format.format(month);

    return month_date;
}

public static String getNextDateMonth()
{
    Date date=new Date();

    Format month_next_format = new SimpleDateFormat("yyyy-MM-01");

    Calendar cal = Calendar.getInstance();

    cal.setTime(date);

    cal.set(Calendar.MONDAY,1);//下个月初

    Date month_next = cal.getTime();

    String month_next_date=month_next_format.format(month_next);

    return month_next_date;
}

public static String getDateWeek()
{
    Date date=new Date();

    Format week_format = new SimpleDateFormat("yyyy-MM-dd");

    Calendar cal = Calendar.getInstance();

    cal.setTime(date);

    cal.add(Calendar.DAY_OF_MONTH,-7);//当前日期-7天

    Date week = cal.getTime();

    String week_date=week_format.format(week);

    return week_date;
}

public static String getDay()
{
    Date date=new Date();

    Format day_format = new SimpleDateFormat("dd");//当前日

    Calendar cal = Calendar.getInstance();

    cal.setTime(date);

    cal.getTime();//当前日

    Date day = cal.getTime();

    String day_date=day_format.format(day);

    return day_date;
}

}

现在我们就可以在jmeter中调用BeanShell 取样器，如下图：

接下来在BeanShell 中引用DateUtil.java，代码如下：
source(“D:\apache-jmeter-5.1.1\bin\DateUtil.java”);
变量名不太规范，不要学我哦！

最后我们在接口中引入BeanShell 的变量，如下图

OK，至此BeanShell 取样器调用Java代码就结束了，谢谢
