java - 创建类路径资源中定义的名为 'sessionFactory' 的 bean 时出错...找不到类

Question

我有一个项目， Spring 配置工作得很好。但是，现在我尝试创建一个 Maven 项目并将所有包复制到新的 Maven 项目中，当我在 Tomcat 服务器上运行它时，我得到异常:找不到我的 sessionFactoryBean 的类。

我不明白为什么我的 Maven 项目无法找到我的 springframework 配置的带注释的类，而类的路径显然是正确的。

我的 Spring 配置:

    <context:annotation-config />
<tx:annotation-driven transaction-manager="transactionManager" />

<!-- Database config -->
<import resource="datasource.xml" />

<bean id="transactionManager"
    class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource" />
</bean>

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="annotatedClasses">
        <list>
            <!-- item -->
            <value>domain.item.Format</value>
            <value>domain.item.Option</value>
            <value>domain.item.Category</value>
            <value>domain.item.Item</value>
            <value>domain.item.ItemPrice</value>
            <value>domain.item.PriceDiscount</value>

            <!-- location -->
            <value>domain.location.Address</value> ....

我的 web.xml

    <listener>
    <listener-class>
        org.springframework.web.context.ContextLoaderListener
    </listener-class>
</listener>

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring.config.xml</param-value>
</context-param>

<servlet>
    <servlet-name>Jersey Web Application</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <param-value>Presto.RestServer</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>Jersey Web Application</servlet-name>
    <url-pattern>/webapi/*</url-pattern>
</servlet-mapping>

Answer 1

昨天我遇到了同样的问题，然后我看到了这个问题，但没有正确的答案。因此，将来如果有人遇到此错误，这里就是解决方案。

我遇到了同样的问题。同样的错误出现了。问题出在 pom.xml 中。如果您在 pom.xml 中多次添加相同的依赖项，您将收到此错误。就我而言，我正在使用

<dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jstl</artifactId>
            <version>1.2</version>
        </dependency> 
<dependency>
            <groupId>jstl</groupId>
            <artifactId>jstl</artifactId>
            <version>1.2</version>
        </dependency> 

这只不过是相同的。当我删除对组 id jSTL 的依赖时，错误就消失了。在您的情况下，您多次使用以下依赖项。

<dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-expression</artifactId>
        <version>4.2.6.RELEASE</version>
    </dependency>

删除其中任何一个，希望您的问题能够得到解决。
