Question

我有一个独立的spring应用程序，主要包含aspecj方面和少数其他spring托管bean，并且捆绑在一个带有maven-assembly插件的jar中，所有spring依赖项都捆绑在jar中并添加到weblogic类路径中。

目标是使用aspectJ代理在运行时将库中的方面编入weblogic中的所有正在运行的应用程序。

问题在于，当我在类路径中添加我的jar文件并重新启动服务器时，在部署现有Web应用程序时会出现ClassNotFoundException。

我知道它不是一个不在lib文件夹中的jar文件，因为app在apppath中没有我的jar文件就可以正常部署。

注意：当我将spring jar文件放在domain / lib文件夹中时，我也得到classNotFoundException。

你能不清楚为什么正在运行的应用程序会受到我的基于弹簧的库的影响？

请参阅下面的stacktrace：我非常确定javax.validation.ValidatorFactory位于WEB-INF \ lib文件夹内的validation-api中。因为我只在将自定义jar文件添加到weblogic类路径时才会出现此异常。

Answer 1

如果您正在使用maven来构建jar，请尝试构建包含嵌入式依赖项的jar文件并对其进行测试，以下链接可以帮助您完成此操作：

How can I create an executable JAR with dependencies using Maven?

Answer 2

依赖关系树显示：

commons-logging的两个版本：1.1和1.1.1
slf4j的两个版本：1.5.6和1.6.1
javax.transaction的范围是compiled，而不是provided
来自不同来源的各种版本的Hibernate工件org.hibernate:com.springsource.org.hibernate:jar:3.3.2.GA:compile org.hibernate:com.springsource.org.hibernate.annotations:jar:3.4.0.GA:compile org.hibernate:hibernate-validator:jar:4.2.0.Final:compile

由于ClassLoader在没有任何确定或预定义顺序的情况下加载资源，因此添加jar文件可能已更改此顺序，现在可以看到类冲突 - 在EAR / WAR本身内部或在应用程序服务器和应用程序之间。

将冲突来源指向所提供的信息并不明显，但它可能是org.hibernate:hibernate-validator，您应该将其版本与核心包对齐，因此来自3.3.2.GA的{{1}}也是如此。

要清除诊断，请使用com.springsource选项运行WebLogic JVM并查看stderr输出。失败之前的最新加载资源以及之前加载的相关类的日志是消除包装造成的这种冲突的最佳线索。

如果冲突来自应用程序服务器程序包而您无法与同一版本对齐，则WebLogic允许您按程序包设置类加载筛选以强制加载您自己的版本。请参阅Using a Filtering Classloader from classloading documentation部分。

Answer 3

听起来像是一个Jar Hell ...如果你有同一个jar的不同版本，你的容器只加载第一个...现在，想象一下它是否加载jar 1的版本5，以及版本2的依赖jar 2（但正确的版本是5）...并且可以在你的系统中发生大的崩溃...为了防止它，一些容器只是不加载任何版本，并给出一些消息，如ClassNotFoundException。
