Question

我正在构建一个基于Spring和Hibernate的项目，灵感来自我下载的Spring MVC tutorial。我基本上继承了pom.xml并通过它构建了Eclipse项目，从头开始编写Java代码。无论如何，我确信我的是一个依赖性问题。

昨天我在加载Hibernate时因为pom.xml而向NoClassDefFoundError: javax/persistence/Entity添加了Java EE依赖项。我用Google搜索并建议添加Java EE

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>6.0</version>
</dependency>

但是现在我得到了SEVERE: Error configuring application listener of class com.sun.faces.config.ConfigureListener java.lang.ClassNotFoundException: com.sun.faces.config.ConfigureListener

我的项目是Spring MVC REST API。我已经读过这个错误是由于缺少JSF实现引起的，但我不需要这里的JSF，也不知道如果我真的需要它，如何将它添加到pom.xml。

我在web.xml中找不到对此课程的引用（所以我可以在没有它的情况下工作）。 Hibernate AFAIK似乎不需要它（HB也适用于普通的旧Java控制台应用程序，不需要JSF）。

如何修复项目？

升级到Hibernate 4解决了这个问题。

我有其他人，也许我现在可能已修好了。此问题现已解决。

从HB 3迁移到4迫使我执行一些bean调整

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="configLocation">
        <value>classpath:/hibernate.cfg.xml</value>
    </property>
    <!-- <property name="configurationClass"> <value>org.hibernate.cfg.AnnotationConfiguration</value> 
        </property> -->
</bean>


<bean id="session" class="org.springframework.orm.hibernate4.SessionFactoryUtils"
    factory-method="openSession" scope="prototype">
    <constructor-arg ref="sessionFactory" />
    <!-- <constructor-arg value="true" /> -->
    <!-- This is seems to be needed to get rid of the 'No Hibernate Session' 
        error' -->
    <!-- <aop:scoped-proxy /> -->
</bean>

无法部署WAR：ClassNotFoundException - 我还缺少什么？

如何修复项目？
