解决方案

缺少jar包

import org.hibernate.criterion.DetachedCriteria;
import org.hibernate.criterion.MatchMode;
import org.hibernate.criterion.Order;
import org.hibernate.criterion.Restrictions;

这几个包有没有

解决方案二：

hibernate中异常：java.lang.ClassNotFoundException: org.hibernate.cache.internal.NoCacheProvider
Tomcat：java.lang.ClassNotFoundException
java异常总结---1.java.lang.ClassNotFoundException: org.springframework.orm.hibernate4.support.OpenSessio
----------------------

解决方案三：

类找不到，是否是包引用的不完整

解决方案四：

找不到类，可能是缺少jar包

解决方案五：

解决方案六：

org.hibernate.criterion.DetachedCriteria 就应该在hibernate-core里，你的路径貌似有问题。
lib应该在webapps/WEB-INF/下，而不是在webapps下

解决方案七：

依赖jar不全吧，检查下导入的jar。
