"update classpath" 在 Java 或 SpringBoot 中是什么意思？
What is "update classpath" mean in Java or SpringBoot?
我正在阅读 Spring boot reference guide about the developer tools，它提到了以下内容：
As DevTools monitors classpath resources, the only way to trigger a restart is to update the classpath. The way in which you cause the classpath to be updated depends on the IDE that you are using. In Eclipse, saving a modified file will cause the classpath to be updated and trigger a restart. In IntelliJ IDEA, building the project (Build → Make Project) will have the same effect.
我很困惑，"update the classpath"是什么意思？更准确地说：
- 如果我修改 IDE 中的文件，它似乎不会更新类路径，这是否正确？
- 如果我在 IntelliJ 中单击 "Build"，它似乎确实更新了类路径，但 IDE 究竟做了什么？
明确地说，class路径指定项目中用户定义的classes 的位置（路径）。通常，当更改 class（文件）以查看操作中的更改时，需要手动重新启动 Spring 启动应用程序。
如您所述，spring-boot-devtools 提供 Automatic Restart:
Applications that use spring-boot-devtools automatically restart whenever files on the classpath change. This can be a useful feature when working in an IDE, as it gives a very fast feedback loop for code changes. By default, any entry on the classpath that points to a folder is monitored for changes. Note that certain resources, such as static assets and view templates, do not need to restart the application.

意思是，使用 IntelliJ，在构建项目时（从而更新 class路径），开发工具将触发应用程序的重启。更简单的是，还可以将 IntelliJ 设置为自动构建并激活 compiler.automake.allow.when.app.running ().
