类路径是每个 spring 应用程序上下文还是每个 JVM？

[英]Is classpath per spring application context or per JVM?

Consider I have two Spring projects that have the same filename inside the classpath.考虑我有两个 Spring 项目，它们在类路径中具有相同的文件名。 For example:例如：

SpringProject-1: @PropertySource(value = "classpath:database/abc.properties") and abc.properties has "name"="abc" SpringProject-1：@PropertySource(value = "classpath:database/abc.properties") 和 abc.properties 有 "name"="abc"

SpringProject-2: @PropertySource(value = "classpath:database/abc.properties") and abc.properties has "name"="Xyz" SpringProject-2：@PropertySource(value = "classpath:database/abc.properties") 和 abc.properties 有 "name"="Xyz"

Now, these projects are created as jar(s) and are added into third spring project, let's say the main-spring-project.现在，这些项目被创建为 jar(s) 并被添加到第三个 spring 项目中，比如说 main-spring-project。

Now, if I want to access the classpath from the main-spring-project, shall I expect conflict in the properties(ie having either "name"="abc" or "name"="Xyz") or shall I get separate abc.properties for each project(ie one abc.properties for springProject1 and one for springProject2)现在，如果我想从 main-spring-project 访问类路径，我应该期望属性冲突（即具有“name”=“abc”或“name”=“Xyz”）还是应该获得单独的 abc每个项目的 .properties（即一个用于 springProject1 的 abc.properties 和一个用于 springProject2 的）

Is classpath is per spring-context or per JVM context?类路径是每个弹簧上下文还是每个 JVM 上下文？

Classpath is JVM specific.类路径是 JVM 特定的。 If you have multiple Spring instances running on a single JVM, then they will all share the classpath.如果您有多个 Spring 实例在单个 JVM 上运行，那么它们都将共享类路径。 However if they are running on multiple JVMs, they will have their own classpaths但是，如果它们在多个 JVM 上运行，它们将有自己的类路径
