Question

我使用spring 4.1.0.RELEASE创建了一个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>

启动时应用程序失败，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，应用程序在我的所有队友系统上运行良好，但在我的系统上运行不正确。

非常感谢任何帮助。

如果加载jar有问题，则会发生java.lang.NoSuchMethodError。我认为在你的机器上你试图运行这个代码，将CLASSPATH设置为一个加载旧版本jar的路径。

您的共享文件夹或类路径中可能存在较低版本的Spring jar。
如果是maven项目，请执行mvn依赖：树并检查任何其他依赖项是否正在加载较低版本的spring。
您可以看到应用程序中加载的所有jar的路径。

public static void main（String [] args）{

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

}

标有@Configuration的Bean在创建时失败，无法启动应用程序
