Spring&Hibernate配置(使用Maven)：java.lang.ClassNotFoundException：org.hibernate.cfg.Configuration
作者：互联网
我正在尝试在Weblogic 10.3服务器上运行的应用程序中包含spring和hibernate.当我在服务器上运行应用程序时,在访问TestServlet以检查我的配置时,出现以下异常：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mySessionFactory' defined in class path resource [spring-config/HorizonModelPeopleConnectionsSpringContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.orm.hibernate3.LocalSessionFactoryBean]: Constructor threw exception; nested exception is java.lang.NoClassDefFoundError: org.hibernate.cfg.Configuration

我已经检查了我的应用程序,并且包含了hibernate jar文件,它包含它说缺少的类：org.hibernate.cfg.Configuration.
该应用程序是使用maven构建的.这些是使用spring和hibernate的JAR文件的依赖项：
<!-- Frameworks -->
<!-- Hibernate framework -->
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate</artifactId>
<version>3.2.7.ga</version>
</dependency>
<!-- Hibernate uses slf4j for logging, for our purposes here use the simple backend -->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.5.2</version>
</dependency>
<!-- Hibernate gives you a choice of bytecode providers between cglib and javassist -->
<dependency>
<groupId>javassist</groupId>
<artifactId>javassist</artifactId>
<version>3.4.GA</version>
</dependency>
<!-- Spring framework -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-orm</artifactId>
<version>2.5.6</version>
</dependency>
起初我以为spring和hibernate库中的版本可能是个问题,所以我尝试了不同的版本,但是仍然找不到任何地方指出哪个库版本兼容.刚知道Spring 2.5.x需要休眠> = 3.1
这是我的Spring配置文件：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
<bean id="myDataSource"

<property name="jndiName">
<value>jdbc/WebCenterDS</value>
</property>
<!--property name="resourceRef">
<value>true</value>
</property>
<property name="jndiEnvironment">
<props>
<prop key="java.naming.factory.initial">weblogic.jndi.WLInitialContextFactory</prop>
<prop key="java.naming.provider.url">t3://localhost:7001</prop>
</props>
</property-->
</bean>
<bean id="mySessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="myDataSource"/>
<property name="configLocation">
<value>classpath:hibernate-config/hibernate.cfg.xml</value>
</property>
<property name="mappingResources">
<list>
<value>classpath:com/horizon/model/peopleconnections/profile/internal/bean/CustomAttribute.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<value>hibernate.dialect=org.hibernate.dialect.HSQLDialect</value>
</property>
</bean>
<bean id="profileExtensionDAO"
class="com.horizon.model.peopleconnections.profile.internal.dao.ProfileExtensionDAOImpl">
<property name="sessionFactory" ref="mySessionFactory"/>
</bean>
</beans>

我缺少任何依赖项或配置吗？
如果我在没有弹簧的情况下使用休眠方式(使用相同的库),则不会得到ClassDefNotFoundException：
导入java.net.URL;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class HibernateUtil {
private static final SessionFactory sessionFactory = buildSessionFactory();
private static SessionFactory buildSessionFactory() {
try {
// Create the SessionFactory from hibernate.cfg.xml
URL hibernateConfigURL = HibernateUtil.class.getClassLoader().getResource("hibernate-config/hibernate.cfg.xml");
return new Configuration().configure(hibernateConfigURL).buildSessionFactory();
}
catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
这使我认为休眠库未正确选择不是问题.在开始从ApplicationContent构建Bean时,似乎正确地选择了Spring库.这两个库相互看不见是一个问题吗？
解决方法:
我的猜测是您的应用程序未在Web应用程序中使用Spring JAR,而是由WebLogic提供的,而那些在战争中无法“看到” Hibernate JAR的应用程序.
要告诉Weblogic查看war文件,请提供一个WEB-INF / weblogic.xml,并将preferred-web-inf-classes设置为true(由于WLS中捆绑了ANTLR版本,因此Hibernate仍然需要这样做)：
<?xml version="1.0" encoding="UTF-8"?>
<weblogic-web-app xmlns="http://www.bea.com/ns/weblogic/90" xmlns:j2ee="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.bea.com/ns/weblogic/90 http://www.bea.com/ns/weblogic/90/weblogic-web-app.xsd">
<context-root>/myApp</context-root>
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
</weblogic-web-app>
