我是Spring的新手，并试图通过我的第一个Spring启动应用程序。我使用Spring Tool Suite作为我的IDE。
在应用程序即时创建中，用户应该能够在查看后编辑特定记录。即时通讯使用路径变量注释来获取jsp中的ID，即我正在查看记录到jsp im用于编辑记录。我已经使用JQuery进行前端验证，并且我已经注意到JQuery验证可以在任何地方工作，除了在我使用路径变量的地方。
我到处寻找解决方案，但似乎无法找到任何成功解决这个问题的方法。
这是我的控制器

在使用@Path变量从URI获取id之前，Jquery验证工作正常。请帮我！非常感谢提前！
找到了解决方案。您只需要在jsp中添加/在脚本src路径前面。
