jmeter 利用脚本读取excel 获取测试用例，并动态设置变量。

1、前置控制器的BeanShell 脚本。代码如下

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

import jxl.Cell;
import jxl.Sheet;
import jxl.Workbook;
String path = "E:/autoTest/Jemter/demo/test_case_data.xls";
Workbook readwb = null;
// 构建Workbook对象, 只读Workbook对象
// 直接从本地文件创建Workbook
InputStream instream = new FileInputStream(path);
readwb = Workbook.getWorkbook(instream);
// Sheet的下标是从0开始
// 获取第一张Sheet表
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();
Cell cell= null;
// 获取指定单元格的对象引用
List list = new ArrayList();
rsRows = (${__threadNum}+1);
print("线程数============================================== :"+${__threadNum});
for (int i = 0; i < rsRows; i++)//rsRows
{
for (int j = 0; j < rsColumns; j++)
{
cell = readsheet.getCell(j, i);
if(i == 0){
list.add(cell.getContents());
log.info("KEY: "+cell.getContents());
//vars.put("city",readsheet.getCell(1, 1).getContents());
continue;
}
log.info(list.get(j)+" , "+cell.getContents() + " \n");
vars.put(list.get(j),cell.getContents());
//每运行一次,取一行数据设为变量。+"_"+i
}
}
log.info("数据总行数 : "+(cell.getRow()+1)+" 列:"+cell.getColumn());
