Java使用Apache Commons Exec运行本地命令行命令

Posted 2021-01-15 <・)))><<

首先在pom.xml中添加Apache Commons Exec的Maven坐标：

<!-- https://mvnrepository.com/artifact/org.apache.commons/commons-exec -->
<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-exec</artifactId>
    <version>1.3</version>
</dependency>

示例代码：

import java.io.IOException;

import org.apache.commons.exec.CommandLine;
import org.apache.commons.exec.DefaultExecutor;
import org.apache.commons.exec.ExecuteException;

public class Test20181025 {
    
    public static void main(String[] args) throws ExecuteException, IOException {
        String line = "ping 127.0.0.1";
        CommandLine cmdLine = CommandLine.parse(line);
        DefaultExecutor executor = new DefaultExecutor();
        int exitValue = executor.execute(cmdLine);
        System.out.println("exit value = " + exitValue);
    }
}

输出结果如下：

???? Ping 127.0.0.1 ???? 32 ????????:
???? 127.0.0.1 ????: ???=32 ???<1ms TTL=64
???? 127.0.0.1 ????: ???=32 ???<1ms TTL=64
???? 127.0.0.1 ????: ???=32 ???<1ms TTL=64
???? 127.0.0.1 ????: ???=32 ???<1ms TTL=64

127.0.0.1 ?? Ping ??????:
    ?????: ????? = 4??????? = 4????? = 0 (0% ???)??
?????г????????(????????λ):
    ??? = 0ms???? = 0ms????? = 0ms
exit value = 0
