【问题讨论】：

环境？你还在用 maven、jpa、spring 还有什么？
显示你在 pom.xml 中的 spring 依赖项
您正在学习为 Spring 3 配置您的应用程序的 Spring 教程，而您正在 pom.xml 中引入 Spring 4 依赖项。我建议寻找使用 Spring 4、Hibernate 4 的教程，因为这些是各自框架的最新版本。
您正在混合春季版本...不要。你正在混合 2.0.8、4.0.6 和 4.1.0 的罐子。删除所有非 4.1.0 的 jar 或确保使用 4.1.0 的等价物。

标签： java spring hibernate

【解决方案1】：

如果你打算使用 hibernate 4 那么：

class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"

在您的会话工厂中。

您的交易经理也是如此：

class="org.springframework.orm.hibernate4.HibernateTransactionManager"

嗯 - 还有更多。您已经设置了 DispatcherServlet，但如果您要在 Web 应用程序中使用 spring，您需要在 web.xml 中使用 ContextLoaderListener，如下所示：

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<context-param>
<param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/spring/spring.xml</param-value>
</context-param>

将你的 bean 定义放在 spring.xml 中 - 你可以让你的 sdnext-servlet.xml 非常简单。

【讨论】：

感谢您的所有 cmets，现在我收到不同的 error.error 消息 org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 12 in XML document from ServletContext resource [/WEB-INF/config /sdnext-servlet.xml] 无效；嵌套异常是 org.xml.sax.SAXParseException；行号：12；列号：64； cvc-elt.1：找不到元素“bean”的声明。

【解决方案2】：

您正在混合使用两个不同版本的 spring 框架，从堆栈跟踪中可以看出：4.1.0.RELEASE 和 4.0.6.RELEASE。这也在您的 pom.xml 中配置不正确。只需更正 pom.xml 以对所有 spring 依赖项使用单个版本，就可以了。

【讨论】：

其实他在混3个版本，里面还有一个2.0.8版本。
做那个 4. 里面还有 1.0.0 版本。尽管已经提出了这一点。没有框架版本的混合！

【解决方案3】：

移除 spring-dao 依赖。春季 4 不需要。

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-dao</artifactId>
    <version>2.0.8</version>
</dependency>

[原因] 因为它调用了 method A 方法，而 spring 4 库中没有该方法。由于这个依赖spring-dao 的优先级更高，spring 4 从这个依赖而不是从相关的spring 4 依赖调用方法method B。 Method B 现在在 spring 4 中修改，不再从 method B 调用 method A。所以method A 从spring 4 中删除。由于spring-dao 不是spring 4 的一部分，并且不知道method A 不再可用，因此崩溃了。

【讨论】：

您能否详细说明为什么删除此依赖项会解决 NoSuchMethodError 问题？
这个解决方案不能解决这个确切的问题，但它可以解决使用@Transactional 注释时出现的另一个错误。也就是说，请查看此链接here
我不知道为什么，但这实际上解决了我的问题。实际上，我只是出于对过去两天被此错误困扰而感到沮丧而尝试了此解决方案，这解决了我的问题！
原因附有答案。

【解决方案4】：

删除 spring-dao 依赖确实可以解决您的问题

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-dao</artifactId>
    <version>2.0.8</version>
</dependency>

spring-dao 已被 spring-tx 取代，请参阅 Spring 的文档，了解 Spring 2.0 和 2.5 中的新增功能？第 2.7.1.2 节。 Spring 2.5 中的 Jar 包装。您会注意到spring-tx api 和spring-dao api 都包含带有重载的 registerAutoProxyCreatorIfNecessary 方法的 AopNamespaceUtils 类。然而，只有在 [spring-dao api 中，该类具有接受对象作为第二个参数的版本。这个调用是由 Spring 反射性地进行的，期望找到一个以对象作为第二个参数的方法，就像 spring-dao 中存在的那样。但是 spring-tx 类被拾取并且没有以 Object 作为第二个参数的方法，因此您会得到下面的异常。

Caused by: java.lang.NoSuchMethodError: org.springframework.aop.config.AopNamespaceUtils.registerAutoProxyCreatorIfNecessary(Lorg/springframework/beans/factory/xml/ParserContext;Ljava/lang/Object;)V
at org.springframework.transaction.config.AnnotationDrivenBeanDefinitionParser.parseInternal(AnnotationDrivenBeanDefinitionParser.java:54) ~[spring-dao-2.0.8.jar:2.0.8]

感谢上面的谢赫·阿卜杜勒·瓦希德 (Sheikh Abdul Wahid) 让我走上了正确的道路。
