Jmeter-采用rt.jar和jxl.jar读取excel

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());   #取值
                        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"))

由于每个线程获取到该线程行的数据，都需要从前往后读取到该线程行，因而进行了大量的vars.put()替换值操作。
优化以上问题：只读取第一行和线程行，再存入vars.put()。

            //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
在接口传参时直接 ${"表头"}
