我最近开始尝试升级几年过时的Struts2 / Spring / Hibernate应用程序的某些依赖项 - 主要是尝试选择@Enumerated注释。 POM越来越清洁,这是一个很好的副作用
所有代码编译并且单元测试通过,但服务器不会以
开头“引起:java.lang.IncompatibleClassChangeError:实现类”
错误消息。
我已经跟踪了几个讨论跟踪依赖项中版本不匹配的线程 - 人们似乎经常会得到两个版本的hibernate。我不认为我有这个问题:
[INFO] [snip MyProjectName]
[INFO] \- org.hibernate:hibernate-entitymanager:jar:3.5.6-Final:compile
[INFO] +- org.hibernate:hibernate-core:jar:3.5.6-Final:compile
[INFO] \- org.hibernate:hibernate-annotations:jar:3.5.6-Final:compile
[INFO] \- org.hibernate:hibernate-commons-annotations:jar:3.2.0.Final:compile
起初我认为3.2.0.Final参考是原因,但进一步的研究使它听起来像是一个空的占位符神器。
我认为我的春天依赖性是问题,但我不知道该修复什么,或者我是否正在寻找另一种红鲱鱼:
[INFO] [snip MyProjectName]
[INFO] +- org.springframework:org.springframework.orm:jar:3.1.1.RELEASE:compile
[INFO] | +- org.springframework:org.springframework.jdbc:jar:3.1.1.RELEASE:compile
[INFO] | \- org.springframework:org.springframework.transaction:jar:3.1.1.RELEASE:compile

[INFO] | \- org.springframework:org.springframework.expression:jar:3.1.1.RELEASE:compile
[INFO] +- org.springframework:org.springframework.core:jar:3.1.1.RELEASE:compile
[INFO] \- org.apache.struts:struts2-spring-plugin:jar:2.2.3.1:compile
[INFO] +- org.springframework:spring-beans:jar:2.5.6:compile
[INFO] +- org.springframework:spring-core:jar:2.5.6:compile
[INFO] +- org.springframework:spring-context:jar:2.5.6:compile
[INFO] \- org.springframework:spring-web:jar:2.5.6:compile
所以我认为我看到了两个可能的问题
struts2-spring-plugin正在引入旧版本的spring - 但是到目前为止我发现的每个web资源都说struts2-spring-plugin应该适用于新版本的spring。我在这里做错了吗?我还没有找到其他较新版本的插件。
我不得不切换到ERB spring存储库以便找到spring的新版本,因此artifactIds在两者之间不匹配 - 直接的spring依赖项是org.springframework:org.springframe 。{component}而间接是org.springframework:spring- {component}。这是一个问题吗?我试图在ERB spring存储库中查找struts2-spring-plugin,但它们没有托管它,所以我怀疑我能找到一个与artifactId命名方案匹配的版本。
我正在列出pom的完整依赖部分,以防上述两个都是红色鲱鱼。我是否应该使用其他工具/调查来找出问题?谢谢。

答案 0 :(得分:1)
如果你打算使用不同于它的版本,你需要从struts 2 spring插件中排除spring依赖项。
