Spring表单标签JasperException异常求助:URI无法解析
Tomcat运行Spring MVC应用时JasperException无法解析Spring Form标签URI
我已经折腾这个问题快一周了,搜遍了能找到的解决方案都没搞定,实在没头绪了,来这儿求各位大佬给点线索!
我在运行包含add.jsp的Tomcat Spring MVC应用时,遇到了这个异常:
JasperException: The absolute uri: [http://www.springframework.org/tags/form] cannot be resolved in either web.xml or the jar files deployed with this application.
