Technical Difficulty Thinking How to Integrate SpringBoot with Jmeter Development

Requirements Overview

Build a high-performance stress testing platform, which needs to call JMeter through the Spring Boot framework for automated stress testing.

Solution 1: Use the Runtime class to call an external process

Technical Overview

Java's Runtime class provides an interface for interacting with the operating system, allowing Java applications to execute system commands, start external applications or scripts, and interact with them. The following is the application of the Runtime class in this scenario:

1. Starting and managing processes: Use the exec() method of the Runtime class to start the JMeter command line tool for stress testing.
2. Accessing system resources: Monitor the memory usage of the Java virtual machine through the methods of the Runtime class, such as totalMemory() and freeMemory().
3. Perform a specific action: Use the exit() method provided by the Runtime class to safely terminate the application, and use nanoTime() and currentTimeMillis() to obtain accurate time information.

Runtime Class

RuntimeThe Java class is a core class that provides methods for interacting with the Java runtime environment.

It provides an interface for interacting with the operating system, enabling Java applications to execute system commands, access system resources, and perform specific operations.

The main uses include the following aspects:

• Starting and managing processes

  • RuntimeThe class provides some methods, such asexec(), used to start and manage external processes.

  • This enables Java applications to execute system commands, launch other applications or scripts, and interact with external processes.

• Accessing system resources

  • RuntimeThe class provides some methods, such astotalMemory()andfreeMemory(), used to obtain the memory information of the Java virtual machine.

  • You can also usegetSystemResource()Method to obtain system resource paths, such as class paths, library paths, etc.

• Perform a specific action

  • RuntimeThe class also provides some methods, such asexit(), which is used to terminate the Java application.

  • You can also usenanoTime()Method to get the current nanosecond time, and usecurrentTimeMillis()Method to get the current millisecond time.

Detailed explanation of JMeter command line stress test

Go to JMeter’s bin directory.

Starting JMeter with command line parameters

./jmeter -n -t /Users/xdclass/Desktop/report.jmx -l /Users/xdclass/Desktop/temp/jtl/result.jtl -e -o /Users/xdclass/Desktop/temp/result

include:

• -n: Run JMeter in non-GUI mode.
• -t <jmx文件路径>: Specifies the path to the JMeter test script.
• -l <结果日志路径>: Specify the path to save the test result log. Make sure the folder exists and the file names are unique.
• -e: Generate a test report in HTML format after the test script is run.
• -o <报告目录路径>: Specify the directory where the HTML report is stored. Make sure the folder exists.

Coding Practice

public class JMeterIntegration {
 
    public static void main(String[] args) {
        try {
            // 构建JMeter命令行调用
            String command = "/path/to/jmeter/bin/jmeter -n -t /path/to/test.jmx -l results.log -e -o /path/to/result";
            Process process = Runtime.getRuntime().exec(command);
 
            // 读取JMeter输出
            new BufferedReader(new InputStreamReader(process.getInputStream())).lines()
                .forEach(System.out::println);
 
            // 等待JMeter进程结束并获取退出码
            int exitCode = process.waitFor();
            System.out.println("JMeter process exited with code: " + exitCode);
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}

Problems

• Poor readability, maintenance and scalability, difficult to platformize, and stuck to existing cognition
