Question

我正在尝试使用Spring mvc和Spring数据来实现一个应用程序。当我尝试持久化对象时，一切正常，但是当我想在服务器上部署应用程序时，我得到一个例外，如下所示：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory': Failed to introspect bean class [org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean] for lookup method metadata: could not find class that it depends on; nested exception is java.lang.NoClassDefFoundError: javax/persistence/SharedCacheMode

pom.xml是

 <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.data</groupId>

                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
    <dependencies>

        </dependency>
    </dependencies>

applicationContext是

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jpa="http://www.springframework.org/schema/data/jpa"
       xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jdbc="http://www.springframework.org/schema/jdbc"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd 
       http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd
         http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc.xsd 
         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
    <context:component-scan base-package="com.amir"/>
    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://localhost:3306/amirdb"/>
        <property name="username" value="root"/>
        <property name="password" value="root"/>
    </bean>

    <jpa:repositories base-package="com.tsi"/>

    <tx:annotation-driven/>
    <!--<jdbc:embedded-database id="dataSource" />-->
    <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="packagesToScan" value="com.tsi"/>
        <property name="jpaProperties">
            <props>
                <prop key="hibernate.hbm2ddl.auto">create</prop>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
            </props>
        </property>
        <property name="dataSource" ref="dataSource"/>
        <property name="jpaVendorAdapter">
            <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
                <property name="generateDdl" value="true"/>
                <property name="showSql" value="true"/>
            </bean>
        </property>
    </bean>
    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactory"/>
    </bean>
</beans>

对于mvc，使用另外两个Spring Congfig文件，它们是rootContext

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
    <import resource="classpath:applicationContext.xml"/>
</beans>

和dispatcher-servlet是

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

    <bean id="conversionService"
          class="org.springframework.format.support.FormattingConversionServiceFactoryBean" />
    <mvc:annotation-driven conversion-service="conversionService">
        <mvc:argument-resolvers>
            <bean class="org.springframework.data.web.SortHandlerMethodArgumentResolver"/>
            <bean class="org.springframework.data.web.PageableHandlerMethodArgumentResolver">
                <property name="maxPageSize" value="3"/>
            </bean>
        </mvc:argument-resolvers>
    </mvc:annotation-driven>

    <bean class="org.springframework.data.repository.support.DomainClassConverter">
        <constructor-arg name="conversionService" ref="conversionService"/>
    </bean>

    <context:component-scan base-package="com.its" />

    <bean id="viewResolver"
          class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/" />
        <property name="suffix" value=".jsp" />
    </bean>

</beans>

在实体类中，我使用import javax.persistence.*;来启用@Entity注释。我想，也许我正在混合使用不同的版本并尝试阅读相关文档，但我没有找到任何内容。任何建议都将受到高度赞赏。
