我知道这个问题被问了很多次，但我已经听懂了所有答案(至少感觉是这样)，但仍然无法弄清楚哪里出了问题以及为什么会出现这些异常。
我正在尝试使用 Maven 构建一个简单的 Spring MVC webapp，我将在数据库中拥有能够登录的用户。遵循几个教程来这样做，一切似乎对我来说都是正确的。
这是我的控制台输出:

最佳答案
java.lang.NoSuchMethodError: org.springframework.jdbc.datasource.DataSourceUtils.doCloseConnection(Ljava/sql/Connection;Ljavax/sql/DataSource;)
这通常表明您遇到类加载问题或正在混合 spring 版本。后者的可能性更大。
关于您的配置的另一件事是您正在复制所有 bean!你的DispathcerServlet和 ContextLoaderListener正在加载可能导致奇怪问题的相同配置。如果您不需要根上下文，只需删除 ContextLoaderListener .如果你真的需要它拆分你的配置。
除此之外，您的 bean 配置存在缺陷，您还在单个上下文中复制了所有 bean。您正在扫描 bean 并将它们添加为 xml 配置(导致一个 bean 的 2 个实例)。不要那样做。还有 <context:property-placeholder />与PropertyPlaceholderConfigurer相同.
你还有 2 <tx:annotation-driven />元素。
<context:annotation-config /> <context:component-scan /> 已经隐含了.
总而言之，您的配置还需要一些清理/爱。
