【问题讨论】：

你能运行mvn dependency:tree吗？让我们确保依赖项的版本符合您的预期。我运行 mvn 测试。它建立成功这不是我说的，但不管@Sotirios 发现了依赖问题。 【参考方案1】：

你有 JAR 地狱般的情况。

不管什么原因，这个依赖

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-hibernate3</artifactId>
    <version>2.0.8</version>
</dependency>

有一个org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean 类隐藏org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean 类，即。同名，在此依赖项中

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-orm</artifactId>
    <version>3.2.4.RELEASE</version>
</dependency>

而且那个类没有setPackagesToScan 方法。摆脱 spring-hibernate3 依赖。 spring-orm 应该绰绰有余。你可以下载源码here自己查。

【讨论】：

我照你说的做了。错误更改为 org.springframework.beans.factory.BeanCreationException：在 ServletContext 资源 [/WEB-INF/applicationContext.xml] 中创建名称为“transactionManager”的 bean 时出错：bean 初始化失败；嵌套异常是 java.lang.NoClassDefFoundError: Lorg/hibernate/cache/CacheProvider; @user2788424 这是因为在 Hibernate 4 中删除了该类。正如其他人所说，您应该使用 LocalSessionFactoryBean。 @user2788424 见：***.com/questions/7528862/… @user2788424 欢迎您。考虑支持对您有帮助的答案并接受最有用的答案。【参考方案2】：

我认为问题在于属性packagesToScan 占用String array 而不是简单的String。尝试从以下位置更改属性：

<property name="packagesToScan" value="org.peterhuang.myweb" />

到

<property name="packagesToScan">
    <list>
        <value>org.peterhuang.myweb</value>
    </list>
</property>

【讨论】：

您必须进行测试。 Spring 为此使用了转换服务。直接输入值没有问题。哦。我不知道。也许OP可以尝试一下。让我们看看它是否有效。我的意思是它不会改变任何东西。 OP 甚至在他们的评论中说。
