我有一个Spring和Hibernate的Maven项目。当我编译项目时，一切都很好，但是当我在tomcat中运行它时，我发现了以下错误：
org.apache.jasper.JasperException: An exception occurred processing JSP page /WEB-INF/jsp/contact.jsp at line 16

我认为最重要的问题是：
org.springframework.beans.BeanWrapper.setAutoGrowCollectionLimit（I）V
但我不了解它的起源。有人可以帮我吗？
谢谢！
最佳答案
该错误说明了一切：方法setAutoGrowCollectionLimit在要加载到内存的BeanWrapper类的版本上不存在。通常，这是类路径问题，是由类路径上的JAR版本过旧或不兼容引起的。
在这种情况下，请在WEB-INF / lib，EAR（如果有）和应用服务器的各种库目录中查找spring-core.jar文件。确保只有一个副本，并且该版本与您编译时使用的版本相同。
