创建名称为＆＃39; HandlerMapping＆＃39;的bean时出错在ServletContext资源中定义

Question

我正在使用spring mvc使用tomcat 8运行一个项目。但是在运行时它会向我抛出一个初始化错误。我在浏览器中给出了以下url .. http://localhost:8080/CNC/welcome.html

Could not initialize class org.springframework.core.convert.support.DefaultConversionService

我的配置文件如下

cnc-dispatcher-servlet.xml
