java - Spring Web应用程序+ Hibernate问题: Unsatisfied dependency expressed through field

Question

我正在学习 Spring Web，目前我开始了一门类(class)，我正在关注老师的项目，但我做了一些更改(他使用 H2 数据库，我尝试使用 postgresql)。我遇到了这些异常:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'homeController': Unsatisfied dependency expressed through field 'produtoDAO'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory': Failed to introspect bean class [org.springframework.orm.hibernate4.LocalSessionFactoryBean] for lookup method metadata: could not find class that it depends on; nested exception is java.lang.NoClassDefFoundError: org/hibernate/cfg/Configuration

我尝试在我的依赖项maven中使用其他版本，但结果是相同的。正如我所说，我正在学习 Spring，如果这是一个愚蠢的问题，我很抱歉。我认为这可能是一些依赖性或 ApplicationContext 问题，但我不确定:/。

编辑:这是一个依赖问题，我正在使用 Intellij IDEA，由于某种原因 Intellij 没有更新依赖库，在我删除 lib 文件夹并直接更新它工作的所有 .jar 文件后:)

Answer 1

ProdutoDAO 使用“@component”而不是“@repository”存在问题
