CacheProvider的异常NoClassDefFoundError [英] Exception NoClassDefFoundError for CacheProvider

问题描述

我在Spring和hibernate中都是新的，所以我试图在Spring 3 + hibernate 4
的基础上实现一些简单的Web应用程序，而我启动tomcat我有这个例外：

  java.lang.NoClassDefFoundError：org / hibernate / cache / CacheProvider 
在java.lang.Class.getDeclaredMethods0（Native Method）
在java.lang.Class.privateGetDeclaredMethods（Class.java:2427）
在java.lang.Class.getDeclaredMethods（Class.java:1791）
 ... 
引起的：java .lang.ClassNotFoundException：org.hibernate.cache.CacheProvider 
在org.apache.catalina.loader.WebappClassLoader.loadClass（WebappClassLoader.java:1678）
在org.apache.catalina.loader.WebappClassLoader。 loadClass（WebappClassLoader.java:1523）
  

我发现这个类是在hibernate-core hibernate 3，但是我没有在hibernate 4中找到它。

我的context.xml的持久性部分：

 < bean id =dataSourcec小姑娘= org.apache.commons.dbcp.BasicDataSource > 
< property name =driverClassNamevalue =org.hsqldb.jdbcDriver/> 
< property name =urlvalue =jdbc：oracle：thin：@IP_Address：SID/> 
< property name =usernamevalue =xxx/> 
< property name =passwordvalue =xxx/> 
< property name =initialSizevalue =5/> 
< property name =maxActivevalue =20/> 
< / bean> 
 
< bean id =sessionFactoryclass =org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean> 
< property name =dataSourceref =dataSource/> 
< property name =packagesToScanvalue =com.huawei.vms.user/> 
< property name =hibernateProperties> 
<道具> 
< prop key =dialect> org.hibernate.dialect.Oracle10gDialect< / prop> 
< / props> 
< / property> 
< / bean> 
  

请帮我找出为什么试图加载CashProvider，因为我没有任何设置context.xml和我在项目中添加的jar。
谢谢！

解决方案

将您的AnnotationSessionFactoryBean更改为 org.springframework.orm.hibernate4.LocalSessionFactoryBean （Hibernate 4），你会很好。 AnnotationSessionFactoryBean被替换为LocalSessionFactoryBean，因为它现在进行类路径扫描。

I'm kind of new in Spring and hibernate so I'm trying to implement some simple web application based on Spring 3 + hibernate 4 while I start tomcat I have this exception:

java.lang.NoClassDefFoundError: org/hibernate/cache/CacheProvider
at java.lang.Class.getDeclaredMethods0(Native Method)
at java.lang.Class.privateGetDeclaredMethods(Class.java:2427)
at java.lang.Class.getDeclaredMethods(Class.java:1791)
    ...
Caused by: java.lang.ClassNotFoundException: org.hibernate.cache.CacheProvider
at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1678)
at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1523)

I've found that this class was in hibernate-core for hibernate 3 but I've not found it in hibernate 4.

The part of my context.xml for persistence:

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
    <property name="driverClassName" value="org.hsqldb.jdbcDriver"/>
    <property name="url" value="jdbc:oracle:thin:@IP_Address:SID"/>
    <property name="username" value="xxx"/>
    <property name="password" value="xxx"/>
    <property name="initialSize" value="5"/>
    <property name="maxActive" value="20"/>
</bean>

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="packagesToScan" value="com.huawei.vms.user"/>
    <property name="hibernateProperties">
        <props>
            <prop key="dialect">org.hibernate.dialect.Oracle10gDialect</prop>
        </props>
    </property>
</bean>

Please help me to figure out why it's trying to load CashProvider because I dont have any settings for that in context.xml and which jar I have to add in my project. Thanks!

解决方案

Change your AnnotationSessionFactoryBean to org.springframework.orm.hibernate4.LocalSessionFactoryBean (Hibernate 4) and you'll be good to go. The AnnotationSessionFactoryBean was replaced with the LocalSessionFactoryBean as it does class path scanning now.
