使用java制作多个cmd命令

Question

您好，我正在尝试使用 java 中的 rman 进行备份，我正在尝试使用 java 中的运行时，我能够打开 cmd，访问 rman，但之后我尝试提交的任何其他查询都将被执行。 我能够从 cmd 窗口和 sqlplus 窗口访问 rman 我已经尝试过使用；没有它 这是代码，请帮助我：

public void execute(JobExecutionContext context) throws JobExecutionException {
         command[0] = "cmd";
         command[1] = "/c";
         command[2] = "rman target / catalog rman/rman@xe;";
         command[3] = "backup as backupset database plus archivelog;";
         command[4] = "exit;";
         command[5] = "sqlplus.exe;";
         try {  
         Process p = Runtime.getRuntime().exec(command);

         BufferedReader reader = new BufferedReader(new InputStreamReader(p.getInputStream()));
         String line = reader.readLine();
         while (line != null) {
             System.out.println(line);
             line = reader.readLine();
         }

这是输出：

Answer 1

参见Problem with the output of a cmd command in java ...特别是如果您有多个命令需要cmd 执行，您必须使用& 符号将它们连接在一起。

Answer 2

如果您想像在“交互式”会话中一样运行命令，则需要生成“cmd.exe”，然后使用p.getOutputStream()“写入”命令来执行。

类似：

ProcessBuilder pb = new ProcessBuilder("cmd.exe");
pb.redirectErrorStream(true);
Process p = pb.start();
PrintWriter writer = new PrintWriter(p.getOutputStream());
writer.println("rman target / catalog rman/rman@xe;");
writer.println("backup as backupset database plus archivelog;");
writer.println("exit;");
writer.println("sqlplus.exe;");

注意：如果您不阅读命令之间的p.getInputStream()，您可能会被阻止。
