java - Spring & hibernate 配置(使用 Maven): java. lang.ClassNotFoundException : org. hibernate.cfg.Configuration

Question

我试图在 Weblogic 10.3 服务器上运行的应用程序中包含 spring 和 hibernate。当我在服务器中运行应用程序时，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>

起初我认为这可能是 spring 和 hibernate 库中版本的问题，所以我尝试了不同的版本，但我仍然找不到任何地方说哪些库版本兼容。刚知道 Spring 2.5.x 需要 hibernate >=3.1

这是我的 Spring 配置文件:

        <property name="hibernateProperties">

    </bean>
</beans>

            spring-tx-2.5.6.jar

我是否缺少任何依赖项或配置？

如果我在不使用 spring 的情况下使用 hibernate(使用相同的库)，我不会得到 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;
    }
}

这让我觉得这不是没有正确选择 hibernate 库的问题。当 Spring 库开始从 ApplicationContent 构建 bean 时，似乎选择得当。会不会是这两个库没有看到对方的问题？

Answer 1

我的猜测是您的应用程序没有使用 webapp 内的 Spring JAR，而是 WebLogic 提供的，而那些无法“看到”war 内的 Hibernate JAR。

要告诉 Weblogic 查看 war 文件，请提供 WEB-INF/weblogic.xml 并将 prefer-web-inf-classes 设置为 true (这是 Hibernate 所必需的，因为 WLS 中捆绑了 ANTLR 版本):

<?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>
