jmeter正则提取值保存本地文件

1.首先正则提取要保存的字段

2.添加后置处理器->BeanShell PostProcessor

代码：

?/*
提前约到的值保存到本地文件中
*/
public static void execParam()
{
String getdata1 = "${code_id}";
// String getdata2 = "${RowNumForSamplers2}";
String filename = "E:/pk.csv";
FileWriter writer;
??????? try {
??????????? writer = new FileWriter(filename);
??????????? writer.write(getdata1);
??????????? // writer.write("r");
??????????? // writer.write("n"+getdata2);
??????????? writer.flush();
??????????? writer.close();
??????? } catch (IOException e) {
??????????? e.printStackTrace();
??????? }
}
execParam();

3.查看本地文件写入，注：每次执行都会重写哦
