Java NoSuchBeanDefinitionException如何初始化SessionFactoryBean？,java,spring,hibernate,spring-mvc,sessionfactory,Java,Spring,Hibernate,Spring Mvc,Sessionfactory,我有个问题。我试图使用Spring和Hibernate运行我的web应用程序/我有一个奇怪的错误。无此定义异常。Stacktrace是： Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean

我有个问题。我试图使用Spring和Hibernate运行我的web应用程序/我有一个奇怪的错误。无此定义异常。Stacktrace是：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

这是我的web.xml

如果使用@Autowired，则不需要在上下文中像属性一样声明。但它必须在上下文中-->NoSuchBeanDefinition-->找不到它

<bean id="userService" class="com.example.service.impl.UserServiceImpl">
    <property name="userDAO" ref="userDAO" /> 
</bean>
尝试从属性上下文中删除userDAO。--如果您自动连接它，则在上下文中不需要它

但问题似乎出在这个bean上：

<bean id="userDAO" class="com.example.dao.impl.hibernate.HibernateUserDAO" />
无法注入sessionFactory的依赖项，但一切似乎都是正确的：(
为什么不尝试删除会话工厂的@autowired，在hibernateUserDao的上下文中放置get/set add属性ref，只是为了测试发生了什么？

我将从清理配置开始

这个

将servlet-context.xml中的
更改为

<context:component-scan base-package="com.example" use-default-filters="false">
    <context:include-filter type="annotation" value="org.springframework.stereotype.Controller" />
</context:component-scan">



有时Spring实际上想说的是：


There are multiple bean definitions...


我有一个问题：


Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'metadataGeneratorFilter' is defined


我曾经有过这样一个xml文件：


<security:custom-filter ref="metadataGeneratorFilter" before="CHANNEL_FILTER"/>

<beans:bean id="metadataGeneratorFilter"
            class="org.springframework.security.saml.metadata.  MetadataGeneratorFilter">
    <beans:constructor-arg ref="metadataGenerator"/>
</beans:bean>





别让人觉得Hibernate在你的类路径上。确保Hibernate及其所有依赖项都在你的
lib
文件夹中。我确信我的类路径和lib folderIn中所有必需的jar简言之，你的bean都在错误的位置，旁边有很多重复。对于较长的版本，请参阅我的答案。为什么我需要2个xml文件？我看到了许多使用1个xml的示例。因此，我不明白这两个文件中应该分别包含哪些内容？从yuo stacktrace判断，您有一个
ContextLoaderListener
（您使用的是Spring Security）和一个
DispatcherServlet
。它们不应该同时加载同一个xml文件。发布web.xml。您已经有多个文件，所以我看不出问题。基本上，在我提到applicationContext.xml的地方，您应该阅读root-context.xml和servlet-context.xml==dispatcher-servlet.xml。
