Question

我将Grails项目从grails-2.3.7升级到grails-2.4.0并遵循指南http://grails.org/doc/2.4.x/guide/upgradingFrom23.html。但是，尝试运行应用程序现在会产生下面的堆栈跟踪。我该如何解决这个问题？

Answer 1

请运行

grails dependency-report

并检查您的应用程序是否没有使用旧版本的Spring。如果您可以将输出粘贴到问题中，您应该在依赖关系报告中看到一些旧版本的Spring JAR，这会导致问题。 Grails 2.4需要Spring 4.0.5或更高版本

升级到Grails 2.4.0后ClassNotFoundException
