java获取JMeterException:调用bsh方法时出错：未定义参数：saa。使用beanshell取样器时

Question

我正在使用下面的java代码连接到redis并执行某些活动，我在响应中获得了所需的值，但我的beanshell正在用下面的响应消息进行响应：

错误-jmeter。util。BeanShellInterpreter:调用bsh方法时出错：eval源文件：内联计算：`import java。伊奥。输入流；导入java。文本语法异常；导入redis。cli…''：未定义参数：saa

警告-jmeter。协议JAVA采样器豆沙采样器：org。阿帕奇。乔芬。util。JMeterException:调用bsh方法时出错：eval源文件：内联计算：`import java。伊奥。输入流；导入java。文本语法异常；导入redis。cli…''：未定义参数：saa

请查找以下代码以供参考
