java - 如何在单击按钮时从 Java 代码运行批处理文件

Question

单击 jsp 页面中的按钮时，我想运行一个批处理文件。我编写了这段代码来在一个方法中执行一个批处理文件，但它不起作用。请帮帮我。

public String scheduler() {
    String result=SUCCESS;  
    try {

        Process p =  Runtime.getRuntime().exec("cmd /c start.bat", null, new File("C:\\Program Files\\MySQL\\MySQL Server 5.0\\bin\\start"));

        System.out.println("manual scheduler for application.."+p);
    } catch(Exception e) {  
    }
}

Answer 1

添加这段代码，

batFile.setExecutable(true);

//Running bat file
Process exec = Runtime.getRuntime().exec(PATH_OF_PARENT_FOLDER_OF_BAT_SCRIPT_FILE+File.separator+batFile.getName());                                                              
byte []buf = new byte[300];
InputStream errorStream = exec.getErrorStream();
errorStream.read(buf);                              
logger.debug(new String(buf));
int waitFor = exec.waitFor();
if(waitFor==0) {
    System.out.println("BAT script executed properly");
}
