本文介绍了NoSuchBeanDefinitionException如何初始化SessionFactory bean？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有一个问题。我试图运行我的Web应用程序使用Spring和休眠/我有一个奇怪的错误。 NoSuchBeanDefinitionException。 Stacktrace是：

 引起：org.springframework.beans.factory.NoSuchBeanDefinitionException：没有限定bean类型[org.hibernate。 SessionFactory]找到依赖关系：预计至少有一个bean可以作为此依赖关系的自动连线候选。依赖注解：{@ org.springframework.beans.factory.annotation.Autowired（所需=真）} 
。在org.springframework.beans.factory.support.DefaultListableBeanFactory.raiseNoSuchBeanDefinitionException（DefaultListableBeanFactory.java:967）
在org.springframework.beans.factory.support.DefaultListableBeanFactory.resolveDependency（DefaultListableBeanFactory.java:749）$ b $ org.springframework.beans.factory.support.DefaultListableBeanFactory.doResolveDependency（DefaultListableBeanFactory.java:837）
在org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor $ AutowiredFieldElement.inject（AutowiredAnnotationBeanPostProcessor.java:486）

我不知道为什么，因为我在servlet-context.xml中声明了SessionFacory bean：

另外，我注释了所有的DAO实现和服务实现。
任何想法？



新增

这是我的一部分代码： 

  @Repository 
 public class HibernateUserDAO实现UserDAO {
 @Autowired 
 private SessionFactory SessionFactory的; 
 ... 
}

和Service类：

  @Service 
 public class UserServiceImpl实现UserService，UserDetailsS​​ervice {
 @Autowired 
 private UserDAO userDAO; 
 
 @Override 
 @Transactional 
 public void create（User user）throws SQLException {
 userDAO.create（user）;

解决方案

我会开始清理你的配置



这个 

 < context：component-scan base-package =com.example/>

包括所有这些 

 < context：component-scan base-package =com.example/> 
< context：component-scan base-package =com.example.service/> 
< context：component-scan base-package =com.example.service.impl/> 
< context：component-scan base-package =com.example.dao/> 
< context：component-scan base-package =com.example.dao.impl.hibernate/> 
< context：component-scan base-package =com.example.web.controller/> 
< context：component-scan base-package =com.example.entity/>

您正在使用组件扫描，因此不需要显式定义所有的bean如果仍然需要的话，就没用了）。



接下来这两个bean 

 < bean class =org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter/> 
 
< bean class =org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping/>

已被< mvc：annotation-driven />



基本上就是这样 

  < beans xmlns =http://www.springframework.org/schema/beans
 xmlns：context =http://www.springframework.org/schema/context
 xmlns：mvc =http://www.springframework.org/schema/mvcxmlns：xsi =http://www.w3.org/2001/XMLSchema-instance
 xmlns：tx =http：// www.springframework.org/schema/tx
 xsi：schemaLocation =

 http://www.springframework.org/schema/mvc 
 http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd 
 http ：//www.springframework.org/schema/tx 
 http://www.springframework.org/schema/tx/spring-tx- 3.2.xsd> 
 
< context：component-scan base-package =com.example/> 
 
< mvc：annotation-driven /> 
< tx：annotation-driven /> 
 
< bean id =viewResolverclass =org.springframework.web.servlet.view.InternalResourceViewResolver> 
< property name =viewClass
 value =org.springframework.web.servlet.view.JstlView/> 
< property name =prefixvalue =/ WEB-INF / pages //> 
< property name =suffixvalue =。jsp/> 
< / bean> 
 
< bean id =dataSourceclass =org.apache.commons.dbcp.BasicDataSource
 destroy-method =close> 
< property name =driverClassNamevalue =org.h2.Driver/> 
< property name =urlvalue =jdbc：h2：〜/ userdb/> 
< property name =usernamevalue =user/> 
< property name =passwordvalue =pswd/> 
< / bean> 
 
< bean id =sessionFactoryclass =org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean> 
< property name =dataSourceref =dataSource/> 
< property name =annotatedClasses> 
< list> 
< value> com.example.entity.User< / value> 
<值> com.example.entity.Role< /值> 
< / list> 
< / property> 
< property name =hibernateProperties> 
<值> 
 hibernate.dialect = org.hibernate.dialect.H2Dialect 
 hibernate.show_sql = true 
< / value> 
< / property> 
< / bean> 
 
< bean id =transactionManagerclass =org.springframework.orm.hibernate3.HibernateTransactionManager> 
< property name =sessionFactoryref =sessionFactory/> 
< / bean>

不是因为错误不是由于配置不完整，但配置错误。 datasource ， sessionFactory ， transactionManager 和< tx：annotation-driven ../> 必须移动到 applicationContext.xml 。 Nex表示您的applicationContext.xml还应包含扫描所有但控制器的组件扫描。 

 < context：component-scan base-package =com.example> 
< context：exclude-filter type =annotationvalue =org.springframework.stereotype.Controller/> 
< / context：component-scan>

更改<$ c $在您的servlet-context.xml中将c>< component-scan ../> 更改为

 < context：component-scan base-package =com.exampleuse-default-filters =false> 
< context：include-filter type =annotationvalue =org.springframework .stereotype.Controller/> 
< / context：component-scan>

这样可以避免重复实例化您的 @Service 和 @Repository beans。现在正在发生什么（您的 ContextLoaderListener 和 DispatcherServlet ）正在加载并创建相同的bean，这会导致您到其他很好的例外，并在内存重复的旁边，因为每个bean在内存中有两个实例）。

I have a question. I tried to run my web application using Spring and Hibernate/ I have a strange error. NoSuchBeanDefinitionException. Stacktrace is:

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.

Also, I annotated all DAO implementations and service implementations. Any ideas?

Added

This is part of my code:

@Repository
public class HibernateUserDAO implements UserDAO {
   @Autowired
   private SessionFactory sessionFactory;
   ...
}

And Service class:

@Service
public class UserServiceImpl implements UserService, UserDetailsService {
@Autowired
private UserDAO userDAO;

@Override
@Transactional
public void create(User user) throws SQLException {
    userDAO.create(user);
}

解决方案

I would start with cleaning your configuration

This

<context:component-scan base-package="com.example" />

Includes all this

<context:component-scan base-package="com.example" />
<context:component-scan base-package="com.example.service" />
<context:component-scan base-package="com.example.service.impl" />
<context:component-scan base-package="com.example.dao" />
<context:component-scan base-package="com.example.dao.impl.hibernate" />
<context:component-scan base-package="com.example.web.controller" />
<context:component-scan base-package="com.example.entity" />

You are using component scanning so no need to explicitly define all the beans (it would make component scanning pretty useless if that was still needed).

Next these 2 beans

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />

<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />

Are already implied by <mvc:annotation-driven />

Basically leaves you with this

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="

<context:component-scan base-package="com.example" />

<mvc:annotation-driven />
<tx:annotation-driven />

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="viewClass"
        value="org.springframework.web.servlet.view.JstlView" />
    <property name="prefix" value="/WEB-INF/pages/" />
    <property name="suffix" value=".jsp" />
</bean>

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
    destroy-method="close">
    <property name="driverClassName" value="org.h2.Driver" />
    <property name="url" value="jdbc:h2:~/userdb" />
    <property name="username" value="user" />
    <property name="password" value="pswd" />
</bean>

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="annotatedClasses">
        <list>
            <value>com.example.entity.User</value>
            <value>com.example.entity.Role</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <value>
            hibernate.dialect=org.hibernate.dialect.H2Dialect
            hibernate.show_sql=true
        </value>
  </property>
</bean>

<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

Not that it will solve your problem because the error is not due to the fact that the configuration is incomplete, but the configuration is in the wrong place. The datasource, sessionFactory, transactionManager and <tx:annotation-driven .. /> must be moved to the applicationContext.xml. Nex to that your applicationContext.xml should also include a component-scan which scans for everything but controllers.

    <context:component-scan base-package="com.example">
    <context:exclude-filter type="annotation" value="org.springframework.stereotype.Controller" />
</context:component-scan">

Change the <component-scan .. /> in your servlet-context.xml to 

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

This to prevent duplicate instantiation of your @Service and @Repository beans. Which is what is happening now (both your ContextLoaderListener and DispatcherServlet are loading and creating the same beans, which would lead you to other nice exceptions and next to that duplication of memory as you have 2 instances of each bean in memory).
