如何从 JMeter Beanshell 中的 JDBC Sampler 获取对象结果集

问题描述

我在 JMeter 中从 JDBC Sampler 获取结果集对象时遇到问题.JMeter 文档准确地说明了这一点:

I am having trouble getting the result set object from JDBC Sampler in JMeter. The JMeter documentation says this exactly:

Result Variable Name
If specified, this will create an Object variable containing a list of
    row maps. Each map contains the column name as the key and the column
    data as the value.
Usage:
  columnValue = vars.getObject("resultObject").get(0).get("Column Name");

所以，我像这样配置它并且它有效.但是由于上面的文档说我创建了一个行映射列表"，我想我会尝试在 BeanShell 中从它创建一个 List 对象，以使其更具可读性.我尝试这样做，但没有用.有人知道答案吗?

So, I configured it like that and it works. But since the document above says that I creates a "list of row maps", I thought I would try to create a List object from it in BeanShell to make it more readable. I tried doing this but it didn't work. Does anyone know the answer?

List<Map<String,Integer>> results = vars.getObject("resultList");

错误或多或少是这样的:

And the error is more or less something like this:

jmeter.util.BeanShellInterpreter: Error invoking bsh
 method: eval   In file: inline evaluation of:
 ``List<Map<String,Integer>> results = vars.getObject("resultList")

推荐答案

Beanshell 不是 Java，您需要以稍微不同的方式访问它.

Beanshell is not Java, you need to access it a little bit differently.

Beanshell 不太支持那些菱形"括号.请修改您的代码如下:

Those "diamond" brackets are not very supported by Beanshell. Please amend your code as follows:

ArrayList result = vars.getObject("resultList");
for (HashMap table : result) {
    for (Object column : table.keySet()) {
        log.info(column + "=" + table.get(column));
    }
}

以上代码假定您已在 JDBC 请求采样器中将 resultList 设置为结果变量名称".

The code above assumes that you have set resultList as a "Result Variable Name" in your JDBC Request Sampler.

这应该将查询结果打印到 jmeter.log 文件中.

That should print query result into jmeter.log file.
