java - Springframework 无法解析 Controller 上的配置类

Question

我正在使用 eclipse、maven 和 spring 开发一个 j2ee 项目。一切都很顺利，除了我无法解决的奇怪而烦人的行为......

让我们从堆栈跟踪开始:

在谷歌上进行一些搜索后，我发现它可能与类路径问题有关，所以这是我的构建路径(无法发布图片......):

在源文件夹构建路径中: 内网LTTD/src/main/java 包含:全部 排除:无

和我的项目 TreeView :

Java 资源 - src/主/java -com.lttd.controller -FichiersController

所以这似乎不是类路径问题。

我还在谷歌上发现“$1.class”意味着它是一个匿名类...为什么不呢，但我不自己制作它，(我什至不知道如何为 Controller 制作它)。

当我在 FichiersController 中进行任何更改(例如声明变量)时，以及当我在 FichiersController 之后创建的 Controller 中进行任何更改(但不在我之前创建的 Controller 中)时，都会发生此错误。

我找到了一个仍然能够运行该项目的解决方法(这是一个奇怪的解决方法):进行更改后，我必须更改 FichiersController 的一个方法:

TypeFichier fileType = TypeFichier.valueOf(fileTypeString);
switch(fileType)

至:

switch(TypeFichier.valueOf(fileTypeString))

或者相反

switch(TypeFichier.valueOf(fileTypeString))

到

switch(fileType) 

在我的dispatcher-servlet.xml中我有:

<context:component-scan base-package="com.lttd" />

我希望我已经提供了您需要的一切来帮助我了解发生了什么以及如何解决它。请随时询问更多信息。

感谢您的帮助。

也许你已经解决了它，但我只是遇到了同样的问题，奇怪的 $1.class ，对我来说，这是 Eclipse 发布的问题，所以我只是用 Maven 构建了我的 Web 项目，并手动将文件放入我的 tomcat 文件夹中。
