在Spring Boot 2中使用Mybatis时,有时可能会遇到“java.lang.IllegalStateException: Failed to execute CommandLineRunner”的错误。这种错误通常表示在应用启动过程中出现了问题,导致CommandLineRunner接口的方法无法正常执行。要解决这个问题,你可以按照以下步骤进行排查和修复: 检查CommandLineRunner的实现类:首先,确保你...
执行的命令被称为CommandLine,可使用该类的addArgument()方法为其添加参数,parse()方法将你提供的命令包装好一个可执行的命令。命令是由执行器Executor类来执行的,DefaultExecutor类的execute()方法执行命令,exitValue也可以通过该方法返回接收。设置ExecuteWatchdog可指定进程在出错后多长时间结束,这样有效防止了run-away...
String line; while ((line = reader.readLine()) != null) { System.out.println(line); } // 等待命令行执行完毕 int exitCode = process.waitFor(); System.out.println("finished to execute the command, and the exit code : " + exitCode); } catch (IOException e) { e.printStackTrace();...
Commons Exec的核心是Executor接口,它定义了执行外部命令的方法。DefaultExecutor类是这个接口的一个实现,提供了执行外部命令的基本功能。使用CommandLine类,咱们可以方便地构建需要执行的命令和参数。而ExecuteResultHandler接口则允许咱们处理异步执行的命令的结果。
