当我将 Spring 引导应用程序部署到 Linux 服务器时，ProcessBuilder 无法正常工作

Question

 public void pushDataToOPA() throws IOException, InterruptedException {
    ProcessBuilder pb = new ProcessBuilder("curl", "-X", "PUT", "-H", "\"Content-Type: application/json\"", "-d",
            "@data.json", dataUrl);
    Process p = pb.start();
    p.waitFor();

}

当我将 spring 启动应用程序部署到 Linux 服务器时，调用此 pushDataToOPA 方法时，此 data.json 文件不会放入目标 (dataUrl)。但是当我运行我的应用程序在本地时，它成功地将 JSON 文件放到同一个目标（dataUrl）。

 public void updatePolicy() throws IOException, InterruptedException {
    ProcessBuilder pb = new ProcessBuilder("curl", "-X", "PUT", "--data-binary", "@policy.rego", policyUrl);
    Process p = pb.start();
    p.waitFor();
}

但这种方法对双方都有效。

您可以使用以下代码将流程输出重定向到 file：

public void updatePolicy() throws IOException, InterruptedException {
        ProcessBuilder pb = new ProcessBuilder();
        pb.command("curl", "-X", "PUT", "--data-binary", "@policy.rego", policyUrl);
        pb.redirectOutput(new File("outputfilePath"));
        pb.redirectError(new File("errorFilePath"));
        Process p = pb.start();
        p.waitFor();
        }

public void pushDataToOPA() throws IOException, InterruptedException {
        ProcessBuilder pb = new ProcessBuilder("curl", "-X", "PUT", "-H", "\"Content-Type: application/json\"", "-d",
                "@data.json", dataUrl);
        pb.redirectOutput(new File("outputfilePath"));
        pb.redirectError(new File("errorFilePath"));
        Process p = pb.start();
        p.waitFor();
    }

ProcessBuilder is not working correctly when I deploy my Spring boot Application to a Linux server
