这个错误是什么意思???!!!

[Michael_3]

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Invocation of init method failed; nested exception is java.lang.SecurityException: class "org.apache.commons.collections.SequencedHashMap"'s signer information does not match signer information of other classes in the same package



spring配置文件中的sessionfactory没有写错啊

[manbaum]

class "org.apache.commons.collections.SequencedHashMap"'s signer information does not match signer information of other classes in the same package

这不是说的很清楚了。是因为数字签名的问题。SequencedHashMap的数字签名和同一个包下面其他类的数字签名不符。
