Question

我在 applicationContext.xml 中尝试了不同的 sessionFactory。它有同样的问题。任何建议将不胜感激！应用程序上下文.xml

你有 JAR 地狱的情况。

无论出于何种原因，这种依赖

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

有一个org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean班级隐藏org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean班级，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。您可以在此处下载源代码并自行检查。

我认为问题在于该属性packagesToScan占用了 aString 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" />

至

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