您没有包含RegistrationDaoImpl的代码，但是在深入研究堆栈跟踪之后，您是否可能在RegistrationDaoImpl中导入了错误的SessionFactory类？堆栈跟踪表明RegistrationDaoImpl需要一个org.h2.engine.SessionFactory，我希望它需要一个org.hibernate.SessionFactory。尝试在RegistrationDaoImpl中修复SessionFactory的导入，看看这是否解决了您的问题 堆栈跟踪的相关部分： 创建名为“registrationDaoImpl”的bean时出错：注入 自动连线依赖失败；嵌套异常是 org.springframework.beans.factory.BeanCreationException:无法 autowire字段：org.h2.engine.SessionFactory com.cts.Dao.RegistrationDaoImpl.sessionFactory；嵌套异常是 org.springframework.beans.factory.noSuchBean定义异常：否 为找到类型为[org.h2.engine.SessionFactory]的匹配bean 依赖项：至少需要1个符合autowire条件的bean 此依赖项的候选项 替换
import org.h2.engine.SessionFactory;
import org.hibernate.SessionFactory;
解析SessionFactory导入后，您似乎缺少aspectjweaver库。 你可以得到它 如果您使用的是maven：
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjweaver</artifactId>
<version>1.8.7</version>
</dependency>
请您重新阅读这个问题并改进一下格式好吗？没有得到您的答案请解释请包括java代码，包括RegistrationDaoImpl.session工厂的导入语句错误已解决bt仍然获得RegistrationService和Registration DAO未自动连线包括新StackTrace您似乎缺少aspectjweaver库。添加这个库，您是否使用maven？Spring AOP实现，我认为是重用aspectj weaver中的一些类。
import org.hibernate.SessionFactory;
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjweaver</artifactId>
<version>1.8.7</version>
</dependency>
