如何在java中传递bashscript的参数？

Question

我有后续的命令要通过我的java程序运行；

./kafka-topics.sh --动物园管理员zk1.xx.com:2181，zk2.xx.com:2181，zk3.xx.com:2181 -删除-主题testTopic

我把这个bash脚本叫做；

ProcessBuilder builder = new ProcessBuilder(CConstants.KAFKA_TOPIC_SH);
builder.command("--zookeeper","zk1.xx.com:2181,zk2.xx.com:21811,zk3.xx.com:2181",
                "--delete", "--topic", "testTopic");
        builder.start();

但我会跟随错误；

java.io.IOException: Cannot run program "--zookeeper": error=2, No such file or directory
    at java.lang.ProcessBuilder.start(ProcessBuilder.java:1048) ~[?:1.8.0_66]
    at

如何使用参数运行bash脚本？

这里

• -动物园管理员-delet，e--主题是争论
• 其他则是这些薪酬的参数。

Answer 1

调用命令方法时，将重写传递给ProcessBuilder构造函数的命令。构造函数有一个vararg变体，您还可以传递命令参数：

new ProcessBuilder(CConstants.KAFKA_TOPIC_SH, "--zookeeper",
   "zk1.xx.com:2181,zk2.xx.com:21811,zk3.xx.com:2181", "--delete", "--topic",   "testTopic")
   .start();

Answer 2

您所得到的错误显示您的第一个参数被解释为命令名。试试这个：

ProcessBuilder builder = new ProcessBuilder();
builder.command(CConstants.KAFKA_TOPIC_SH,"--zookeeper","zk1.xx.com:2181,zk2.xx.com:21811,zk3.xx.com:2181",
                "--delete", "--topic", "testTopic");
        builder.start();

Answer 3

您可以直接调用Kafka，而不是将java命令封装到bash脚本中。例如,

String[] options =新String[]{

 "--create",

 "--zookeeper",

 "zk\_host:port",

 "--partitions",

 "1",

 "--topic",

 "test",

 "--replication-factor",

 "1"  };

TopicCommand.main(选项)；
