如果CSV文件与Java类位于同一目录下,我们可以使用类路径来读取文件。以下是一个示例代码: importjava.io.BufferedReader;importjava.io.IOException;importjava.io.InputStreamReader;publicclassCSVReader{publicstaticvoidmain(String[]args){StringcsvFile
可以使用java.io和java.nio.file。这些库将帮助我们操作文件。 importjava.io.BufferedReader;// 导入BufferedReader类用于读取文本文件importjava.io.FileReader;// 导入FileReader类用于打开文件importjava.io.IOException;// 导入IOException类用于处理输入输出异常 1. 2. 3. 2. 打开CSV文件 在这一步中,我们需要指...

选择csvread函数,生成函数; 在Jmeter“选项”中-->选择“函数助手对话框”-->选择csvread函数或者直接采用快捷键Ctrl+F打开, 其中: CSV file to get values from | *alias:表示要读取的文件路径,应该是绝对路径(如:D:\Software\jmeter\User parameter.txt) CSV文件列号| next| *alias:表示当前变量读取第几...
点击选项->函数助手对话框-> 选择__CSVRead 点击生成按钮,则生成了函数,如图所示: CSV file to get values from | *alias 指${__CSVRead(,)}中()内的第一个参数,调用文件logins.txt的地址 CSV文件列号| next| *alias 指${__CSVRead(,)}中()内的第二个参数,调用文件logins.txt中第几列的参数,注意...
