我正在开发一个 Spring-MVC 应用程序，我想在其中使用 ，但每当我这样做时，我都会收到如下错误。我已经检查了其他链接是否有类似的问题，但它们对于它所具有的所有选项都没有用。所以我发布一个新问题。
由于项目很大，XML文件也很大。请注意，当我添加时，我的 @Scheduled 方法正在触发，但 servlet 会抛出加载异常，否则，它们不会触发。
错误代码:
org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Failed to import bean definitions from relative location [servlet-context.xml]
Offending resource: ServletContext resource [/WEB-INF/spring/appServlet/security-applicationContext.xml]; nested exception is org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Only one AsyncAnnotationBeanPostProcessor may exist within the context.
Offending resource: ServletContext resource [/WEB-INF/spring/appServlet/servlet-context.xml]
org.springframework.beans.factory.parsing.FailFastProblemReporter.error(FailFastProblemReporter.java:70)
ROOT CAUSE
org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Only one AsyncAnnotationBeanPostProcessor may exist within the context.
Offending resource: ServletContext resource [/WEB-INF/spring/appServlet/servlet-context.xml]
org.springframework.beans.factory.parsing.FailFastProblemReporter.error(FailFastProblemReporter.java:70)
这是我的 servlet-context.xml :

最佳答案
加载 DispatcherServlet 的上下文时似乎发生了错误。
<servlet>
<servlet-name>appServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/appServlet/servlet-context.xml,/WEB-INF/spring/appServlet/security-applicationContext.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
<async-supported>true</async-supported>
</servlet>
您已将其定义为加载 servlet-context.xml 和 security-applicationContext.xml。 但是 security-applicationContext.xml 已经导入 servlet-context.xml。所以你得到了所有的 bean 两次。其中一个 bean 是 AsyncAnnotationBeanPostProcessor，它只能在上下文中出现一次。
所以去掉上面声明中的servlet-context.xml。
此外，您当前正在定义 ContextLoaderListener 和 DispatcherServlet 来加载 XML 上下文配置。为什么？
请参见此处:What is the difference between ApplicationContext and WebApplicationContext in Spring MVC?
关于java - Spring-MVC : Failed to import bean definitions from relative location [servlet-context. xml]，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/30354233/
