为什么我收到上述异常？请帮忙
答案 0 :(得分：2)
此错误意味着在从上下文org.hibernate.Session.connection()检索的hibernate版本中找不到返回类型java.sql.Connection的对象的方法ClassLoader。在你的情况下，你使用包含这个方法的Hibernate 3.2.6.ga，知道自Hibernate 4.0以来已经删除了这个方法，我怀疑它实际上使用捆绑到wildfly中的hibernate版本。
您应该升级spring-orm版本，以便与wildfly的hibernate版本兼容。确实spring-orm 3.0.1.RELEASE取决于hibernate-core 3.3.1.GA（正如您可以看到here），因此它会尝试访问非现有方法，这是此处冲突的根本原因。
