Question

我正在尝试在Spring应用程序中使用Hibernate，但我在项目部署时出错了

Exception while loading the app : java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/dispatcher-servlet.xml]: Initialization of bean failed; nested exception is org.springframework.beans.TypeMismatchException: Failed to convert property value of type 'java.lang.String' to required type 'java.lang.Class' for property 'configurationClass'; nested exception is java.lang.IllegalArgumentException: Cannot find class [org.hibernate.cfg.AnnotationConfiguration].

这里是我的调度程序 - servlet与bean会话工厂：

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
  xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
  http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd"
  default-autowire="byName">

<context:component-scan base-package="hibernateTest" />

<context:annotation-config/>

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

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" 
      p:prefix="/WEB-INF/jsp/" 
      p:suffix=".jsp" />

<bean id="propertyConfigurer" 
      class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="locations">
        <list>
            <value>classpath:jdbc.properties</value>
        </list>
    </property>
</bean> 

 <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="configLocation">
            <value>classpath:hibernate.cfg.xml</value>
        </property>
        <property name="configurationClass">
            <value>org.hibernate.cfg.AnnotationConfiguration</value>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                <prop key="hibernate.show_sql">true</prop>
            </props>
        </property>
</bean>

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

我的hibernate-cfg.xml：

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
<session-factory>
    <mapping class="hibernateTest.web.InventoryController" />
</session-factory>     
</hibernate-configuration>

我的课堂上有很多罐子，而且我不会错过任何人。你能帮我找个问题吗？

由于

Answer 1

您需要将hibernate-annotations.jar放在类路径上。

Answer 2

找不到类[org.hibernate.cfg.AnnotationConfiguration]

这就是原因，你能否在类路径中检查这个类。

Answer 3

org.hibernate.cfg.AnnotationConfiguration已弃用，

并且其所有功能都已移至org.hibernate.cfg.Configuration。

更改您的代码

        <property name="configurationClass">
            <value>org.hibernate.cfg.Configuration</value>
        </property>

Hibernate BeanCreationException
