Java服务包装器 - 保持运行和停止

Question

这是日志文件，显然是服务工作。创建的行文件是从我的程序打印出来的。但它只是不能留下来。我的配置有什么错误？已经尝试了一段时间，但没有任何线索

代码

    public static void main(String[] args) throws IOException {
    ServerSocket listener = new ServerSocket(3002);
        System.out.println("server started");
    try {
        while (true) {
            Socket socket = listener.accept();
            try {
                PrintWriter out =new PrintWriter(socket.getOutputStream(), true);
                out.println(new Date().toString()+"\ntest");
            } finally {
                socket.close();
            }
        }
    }
    finally {
        listener.close();
    }
}

您需要将主类设置为wrapper classes之一。基本上将以下内容添加到您的wrapper.conf：

wrapper.java.mainclass=org.tanukisoftware.wrapper.WrapperSimpleApp
wrapper.app.parameter.1=HelloWorldServer
