run方法是在应用程序启动时被调用的,它是由 Spring Boot 的ApplicationRunner或CommandLineRunner接口实现的。当应用程序启动时,Spring Boot 会创建一个ApplicationContext,然后调用run方法。 在run方法中,我们创建了一个新线程,并在该线程中执行了一些代码。但是,由于run方法是一个同步方法,它可能会阻塞应用程序的启动过...
mvn spring-boot:run 1. 在控制台输出中,你应该能够看到你在run方法中输出的任何日志信息。 至此,你已经成功实现了Java项目的CommandLineRunner。 状态图 下面是一个状态图,展示了CommandLineRunner的执行过程: run()Application startedInitializingRunning 在这个状态图中,我们可以看到CommandLineRunner在项目启动时执行...
at java.lang.Runtime.exec(Runtime.java:591) at java.lang.Runtime.exec(Runtime.java:464) Clearly, the pdflatex command is not supported by the runtime exec bit, but since both commands work as expected from the Terminal, I was wondering if you knew any way to instruct the Terminal...
I/O from the Command Line A program is often run from the command line and interacts with the user in the command line environment. The Java platform supports this kind of interaction in two ways: through the Standard Streams and through the Console. 译:从命令行中进行IO操作 程序经常从命令...
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...

找到Application.java 文件(有可能不是此名称,具体取决于你的应用程序名称,但都会包含有 “application” )。在定义此类的地方,在后面加上 implements CommandLineRunner。这将允许你实现 run 方法来创建命令行应用程序。重写 CommandLineRunner 接口提供的 run 方法,并包含如下内容用来测试 BikeRepository : ...
