java - 当一个项目使用JDK配置时，会加载JDK中的哪个.jar文件？

问题描述

在我的 IntelliJ IDEA 中，当配置 JDK 并为一个项目选择 JDK home 时，将加载下面的类路径/jar 文件。

但是据我所知，JDK主路径中有一些jar文件没有被加载，

例如，尚未加载相同路径下的此文件：/Library/Java/JavaVirtualMachines/jdk1.8.0_161.jdk/Contents/Home/jre/lib/security/policy/limited/US_export_policy.jar。

这如何生效？我可以选择特殊设计的 JDK 并在其他地方加载一些 jar 吗？我在哪里可以更改加载规则，在 IDEA 或 JDK 源代码中？

解决方案

您可以在“项目结构 | SDKs - 类路径”中配置类路径
