小编use*_*680的帖子

我在pom.xml中提供了servlet-api版本2.5作为范围.这是依赖项的一部分:我的项目的树输出."从2.3管理的版本;从编译管理的范围"是什么意思？

[INFO] +- commons-logging:commons-logging:jar:1.1:compile
[INFO] |  \- javax.servlet:servlet-api:jar:2.5:provided (version managed from 2.3; scope managed from compile)

这是否意味着我的类路径上版本2.3存在一些传递依赖？我的WAR文件根本没有servlet-api jar,但是我确实使用了旧版本的Spring 2.5.4.我怀疑Spring框架依赖于servlet-api 2.3.

我正在将Weblogic服务器从9升级到10.3.6.当我试图部署我的耳朵应用程序并得到以下异常.

我尝试了各种各样的事情,包括添加weblogic-application.xml但它仍然无法正常工作.
