Eclipse Maven Spring 项目 - 错误

Question

我需要帮助解决一个让我发疯的错误。
我开始学习 Java EE，并且正在浏览 youtube 上的教程。一切都很顺利，直到我来到 Spring、Hibernate、JSF 准备项目。
我在 pom.xml 项目中添加了依赖项，如下所示，但在我的配置文件中出现错误：
“构建路径不完整，找不到 org/aspectj/weaver/ 的类文件BCException”
我在谷歌上寻找答案，也在这里寻找我的问题的答案。我发现我需要添加 aspectj 依赖项，但它仍然不起作用，我遇到了同样的错误。

我在我的项目中包含了以下库：（所以我想这不是缺少库的问题）

我的 pom.xml 文件：

在这里您可以看到其中一个包含错误的文件：（我删除了 xml 声明并在发生错误的地方添加了 cmets）

非常感谢您的帮助。

我在课堂上检查过 Benzonico，如果 BCExcepction 可见，似乎是。 我还添加了外部 jars aspectj 和 xwork，但它仍然无法正常工作。

问题很奇怪，因为在eclipse左侧的资源管理器选项卡上，当您检查时您会发现类名中没有放置错误。现在在放置代码的 Eclipse 中心，您可以看到出现了该问题。

我仍然需要这个问题的帮助。有人吗？

Answer 1

这并不能直接解决您的问题，但会帮助您解决问题：

您可以做两件事来检查您丢失的类是否在项目的类路径中：

在 Eclipse 中：按 ctrl+shift+t 并输入你的类的名称，如果它没有出现，那么它是不在您的课程路径中。

您还可以使用 findjar 检查哪个 jar 是您的类，并验证该 jar 是否在您的类路径中。

Answer 2

有时，导入库的顺序很重要，请尝试让您的应用更早地加载库。如果您使用 eclipse，请检查构建路径配置、导入顺序。
