我有一个使用 spring 4.1.0.RELEASE 创建的 Spring MVC 应用程序。我有一个类说 A 已用 @Configuration 标记以将其标记为配置类。

应用程序上下文中的 XML 配置如下

<bean id="a" class="A"></bean>

应用程序在启动时失败并出现以下错误。我正在使用带有 jetty 8 插件的 Eclipse。

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'a' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Initialization of bean failed; nested exception is java.lang.NoSuchMethodError: A(class name)(Lorg/springframework/beans/factory/BeanFactory;)V

奇怪的是，该应用程序在我所有的队友系统上运行良好，但在我的系统上却不行。

任何帮助将非常感激。

如果加载的 jar 出现问题，则会发生 java.lang.NoSuchMethodError。我认为在您尝试运行此代码的机器上，已将 CLASSPATH 设置为加载旧版本 jar 的某个路径。

  1. 您的共享文件夹或类路径中可能存在较低版本的 Spring jar。

  2. 如果它是 maven 项目，请执行 mvn dependency:tree 并检查任何其他依赖项是否正在加载较低版本的 spring。

  3. 您可以查看应用程序中加载的所有 jar 的路径。

公共静态无效主要（字符串[]参数）{

URLClassLoader classLoader = (URLClassLoader)CurrentClass.class.getClassLoader(); System.out.println(Arrays.toString(classLoader.getURLs()));

}
