spring bean没有找到对应的类？

Question

错误是

严重 [RMI TCP Connection(2)-127.0.0.1] org.springframework.web.context.ContextLoader.initWebApplicationContext Context initialization failed
 org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userController': Unsatisfied dependency expressed through field 'userService'; nested exception is org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [org.mybatis.spring.SqlSessionFactoryBean] for bean with name 'sqlSessionFactory' defined in class path resource [resources/ApplicationContext.xml]; nested exception is java.lang.ClassNotFoundException: org.mybatis.spring.SqlSessionFactoryBean

我试了在java中可以找到

org.mybatis.spring.SqlSessionFactoryBean

这个类

如何解决？

具体的spring配置文件如下：

Answer 1

应该是包有冲突 换了个版本的包就好了

Answer 3

我试了在java中可以找到，org.mybatis.spring.SqlSessionFactoryBean

你怎么试的呢，在 IDE 里搜？搜得到不能代表运行时也能找到。比如在多模块的项目里，你搜的到只能说明当前 project 的某个 module 里有这个类，不能代表你运行（或依赖）的这个 module 里有个类……

检查下你运行的这个 module 里有没有呢
