Jmeter读取Excel，BeanShell取样器调用rt.jar和jxl.jar

将rt.jar和jxl.jar，放在\apache-jmeter-5.0\lib\ext下面

import java.io.*;
import java.util.ArrayList;
import java.util.List;

import jxl.Cell;
import jxl.Sheet;
import jxl.Workbook;
            String path = "C:/123.xls";
            InputStream instream = new FileInputStream(path);
            Workbook readwb = null;
            Cell cell= null;
            readwb = Workbook.getWorkbook(instream);
            // 获取第一张Sheet表,Sheet的下标是从0开始
            Sheet readsheet = readwb.getSheet(0);
            // 获取Sheet表中所包含的总列数
            int rsColumns = readsheet.getColumns();
            // 获取Sheet表中所包含的总行数
            int rsRows = readsheet.getRows();

            // 获取指定单元格的对象引用
            List list = new ArrayList();
            //线程数(按线程数取行数)
            rsRows = ${__threadNum};

            print("线程数=========== :"+${__threadNum});
            for (int i = 0; i < rsRows; i++) //行
            {
                for (int j = 0; j < rsColumns; j++) //列
                {
                    cell = readsheet.getCell(j,i);
                    //list存第一行名字
                    if( i== 0){
                        list.add(cell.getContents());
                        continue;
                    }
                    //put变量存第二行以后的值（线程3以后会反复替换以前put的值）
                    vars.put(list.get(j),cell.getContents());
                    print(vars.get(list.get(j)));
                }

            }

//log.info("isEnc:"+vars.get("name"));//调用jmeter内置log对象，日志会打印到jmeter.log中

//System.out.println(vars.get(list.get(j)));//打印
//print(vars.get(list.get(j)));//打印
//return vars.get(list.get(j));//返回
//print((vars.get("表头"))

由于list无法传递，则每个线程都需要将第一行表头读取存在list里面；

但线程3以后，会反复读取Excel第二行（前面行）的数据，进行vars.put()替换值操作。

优化以上问题

import java.io.*;
import java.util.ArrayList;
import java.util.List;

import jxl.Cell;
import jxl.Sheet;
import jxl.Workbook;
            String path = "C:/123.xls";
            InputStream instream = new FileInputStream(path);
            Workbook readwb = null;
            Cell cell= null;
            readwb = Workbook.getWorkbook(instream);
            // 获取第一张Sheet表,Sheet的下标是从0开始
            Sheet readsheet = readwb.getSheet(0);
            // 获取Sheet表中所包含的总列数
            int rsColumns = readsheet.getColumns();
            // 获取Sheet表中所包含的总行数
            int rsRows = readsheet.getRows();

            // 获取指定单元格的对象引用
            List list = new ArrayList();
            //线程数(按线程数取行数)
            rsRows = ${__threadNum};
            //该线程只读第一行和应该读的最后一行
            int[] myRows = {0,rsRows-1};

            print("线程数=========== :"+${__threadNum});
            for (int i = 0; i < myRows.length; i++) //行
            {
                for (int j = 0; j < rsColumns; j++) //列
                {
                    cell = readsheet.getCell(j, myRows[i]);
                    //list存第一行名字
                    if(myRows[i] == 0){
                        list.add(cell.getContents());
                        continue;
                    }
                    //put变量只存最后一行的值
                    vars.put(list.get(j),cell.getContents());
                    print(vars.get(list.get(j)));
                }

            }

其实以上两种都不影响最后需要的结果，只是影响效率

在接口调用时直接 ${"表头"}
