). 我有一个Web项目Web1.war

Then I did convert to jar file that web project: Web1.jar
. 然后,我确实将该Web项目转换为jar文件: Web1.jar
。 Afterwards add the Web1.jar
file to another java web project Web2.war
. 然后,将Web1.jar
文件添加到另一个Java Web项目Web2.war

) ? 如何通过jar文件( Web2.war --> Web1.jar --> lib.jar
)从当前项目( Web2.war
)引用该库lib.jar

Java only supports JAR level dependencies. Java仅支持JAR级别的依赖关系。 You mention having converted you 'web project' to a JAR but don't give the details of how you did this. 您提到将“ Web项目”转换为JAR,但是没有提供有关操作方法的详细信息。
By default, Java uses the classpath to find dependencies. 默认情况下,Java使用类路径查找依赖项。 In a 'web project' (WAR) the classpath is the WEB-INF/classes
directory and any JARs in the WEB-INF/lib
. 在“ Web项目”(WAR)中,类路径是WEB-INF/classes
目录以及WEB-INF/lib
中的所有JAR。
If you have classes in one 'web project' (WAR) that you need to use in another 'web project' (WAR) then you have a couple of options, both of which will involve modifying your build: 如果您在一个“ Web项目”(WAR)中需要在另一个“ Web项目”(WAR)中使用的类,则有两个选择,这两个都将涉及修改构建:
or 要么
Update 更新资料
You cannot covert a WAR to a JAR as you have suggested in your edits. 您不能像编辑中所建议的那样对JAR进行WAR转换。 While it's possible to create a custom archive format, a JAR cannot (and should not) contain other JARs. 尽管可以创建自定义存档格式,但JAR不能(也不应)包含其他JAR。
