无法自动装配bean，我正在使用Spring 3.1

Root Cause 
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: rinku.pms.bean.UserBean rinku.pms.controller.UserController.userBean; nested exception is org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [org.springframework.orm.hibernate4.HibernateTransactionManager] for bean with name 'txManager' defined in ServletContext resource [/WEB-INF/dispatcher-servlet.xml]; nested exception is java.lang.ClassNotFoundException: org.springframework.orm.hibernate4.HibernateTransactionManager>```

答案

您的类路径没有spring-orm依赖项。如果您使用的是maven，请将其添加到pom.xml或下载spring-orm并将其添加到您的库中]

<dependency>
   <groupId>org.springframework</groupId>
   <artifactId>spring-orm</artifactId>
   <version>3.1.0.RELEASE</version>
</dependency>
