我有一个Maven应用程序，当我使用xml-jetty运行我的应用程序时，我收到了Failed to read candidate component class, nested exception is ArrayStoreException: java.lang.String类的target/classes/com/test/SampleImpl错误，我看到了原始的SampleImpl.java文件，但无法查找与该文件有关的任何错误。我对该错误进行了一些研究，发现了一些与将Spring的Java版本7更改为8有关的建议，我将Java版本更改为8，并且将Spring版本更改为4.x bt仍然出现相同的错误，然后像其他站点中所建议的那样，我在dependency-management中添加了一些spring依赖项，但仍然出现相同的错误。
