Spring 3.2 配置 tx :annotation-driven error in eclipse

Question

尝试从 Spring 3.0 迁移 -> 3.2.4

使用:Eclipse Juno(在 64 位 java 1.7 上)和 STS 3.3，

问题:Eclipse/STS IDE 中的编辑窗口显示:

Error occurred processing XML 'org/springframework/aop/config/AopNamespaceUtils'

在我使用的线路上 <tx:annotation-driven>

编译项目会导致类似的错误。

java.lang.NoClassDefFoundError: org/springframework/aop/config/AopNamespaceUtils

我一直在努力寻找解决方案。我假设它是我忽略的简单东西，但我终其一生都找不到它。

这是我到目前为止所做的:

• 我使用 Eclipse 从头创建了配置文件 -> 新文件-> STS bean 配置。
• 我已确认 maven 已将适当的 jar 安装到类路径。
• 我已经使用 1.6 和 1.7 版本的 java 进行了编译
• 使用 -clean 启动 eclipse(以防旧项目和工作区版本留下任何工件)
• <tx:annotation-driven>使用普通的 Eclipse ctrl+space 添加
• 显式添加 spring-web 到 pom.xml(Spring 版本 3.2 删除了所需的依赖项，但它没有区别，in or out)
• 显式添加 spring-aop 到 pom.xml

如有任何帮助或见解，我们将不胜感激。

这是我的 config-portlets.xml(它的先前版本在 Spring 3.0 中有效)

    <tx:annotation-driven />  <!-- error here-->

我在我的 pom.xml 中明确包含了 spring-aop-3.2.4.Final

Answer 1

Eclipse/Java/PC 无法理解的故障。我唯一的答案是:让电脑过夜不碰它，它会自行修复。也许，取出电池后重新启动会导致相同的结果。

我只能怀疑发生了一些垃圾收集，这清除了 Java 和/或 Eclipse 中的损坏。
