在類路徑資源中定義名爲'sessionFactory'的bean時出錯...找不到類

我有一個項目，彈簧配置工作得很好。然而，現在我試圖創建一個maven項目並將所有包複製到新的maven項目中，當我在tomcat服務器上運行它時，出現異常：找不到我的sessionFactoryBean的類。在類路徑資源中定義名爲'sessionFactory'的bean時出錯...找不到類

我不明白爲什麼我的maven項目無法找到我的springframework配置的註釋類，當類的路徑顯然是正確的。

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>

老實說，你最好再次使用Spring Boot項目重新啓動並將代碼轉儲到其中。您將取消所有XML配置，即使您的pom將通過引導管理依賴版本得到極大的簡化 - 相信我;這將是值得的努力。 –

請參見下面的事情：

檢查Format類和其他域類也正確註釋。
檢查組件掃描是否正確掃描了存在這些domain classes的所需軟件包。

或者你也可以添加以下屬性：SessionFactory的bean中

<property name="packagesToScan"> 
    <list> 
     <value>domain.item</value> 
    </list> 
</property>

掃描所有註解類和使用AnnotationSessionFactoryBean創建SessionFactory的

嗨，感謝您的回覆，請您詳細解釋一下您的＃2關於如何正確添加組件掃描的更多細節？我嘗試在我的Format類中添加標籤@Component，但這沒有幫助... – William

您必須添加諸如來掃描您的域。項目包。另外如果你的域名是Entity在你的數據庫中映射一個表格，那麼你必須使用@Entity進行註釋。 – shankarsh15

公平地確定這些東西都不相關，因爲'annotatedClasses'屬性被傳遞給'SessionFactory'，並且它是Hibernate搜索類並分析它們。 –

我面臨同樣的問題yestarday然後我看到這個問題，但沒有一個正確的答案。所以在將來如果有人有這個錯誤這裏是解決方案。

我有同樣的問題。同樣的錯誤即將到來。問題出在pom.xml中。如果您在pom.xml中多次添加相同的依賴關係，將會出現此錯誤。在我的情況下，我使用的是

<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>

哪些都是一樣的。當我刪除與組id id jstl的依賴關係時，錯誤消失了。在您的情況下，您多次使用以下依賴項。

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

刪除其中任何一個，並希望您的問題將得到解決。
