Commons Exec - Apache Commons Exec Tutorial

apache commons-Exec 工具库对 Java 调用系统指令提供了封装；

使用示例

/**
     * 执行指定命令
     * 
     * @param command 命令
     * @return 命令执行完成返回结果
     * @throws IOException 失败时抛出异常，由调用者捕获处理
     */

        try (

        ) {
            int exitCode = exeCommand(command, out);
            if (exitCode == 0) {
                System.out.println("命令运行成功！");
            } else {
                System.out.println("命令运行失败！");
            }
            return out.toString(DEFAULT_CHARSET);
        }
    }
