Java代码-在localhost JVM中列出java进程的最佳方法(适用于Linux和Windows)

RuntimeMXBean runtimeMXBean = ManagementFactory.getRuntimeMXBean();

String jvmName = runtimeMXBean.getName();

int processId = Integer.parseInt(jvmName.split("@")[0]);

ProcessBuilder processBuilder = new ProcessBuilder("tasklist", "/FI", "IMAGENAME eq java.exe");
Process process = processBuilder.start();
InputStream inputStream = process.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
String line;
while ((line = reader.readLine()) != null) {
    if (line.contains("java.exe")) {
        String[] parts = line.split("\\s+");
        int processId = Integer.parseInt(parts[1]);
        // 处理进程ID
    }
}
