java - NoClassDefFoundException : javax/persistence/PersistenceContext Spring ORM with Hibernate

我是 Spring 的新手。我正在从 javapoint 学习 spring 。从javapoint学习了一些spring的基础知识后和 spring docs ，我转向使用 spring 学习 hibernate，但在第一次尝试(示例)中，我坚持这样的观点:NoClassDefFoundExpetion: javax/persistence/PersistenceContext.为了解决这个异常，我在 this 上搜索并寻找类似的情况(及其解决方案)。和 this ，但没有任何帮助我。
这里是我的异常的完整stacktrace:

    Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.context.annotation.internalPersistenceAnnotationProcessor': Instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError: javax/persistence/PersistenceContext

我正在使用 eclipse-neon IDE、spring-framework 4.3.2 RELEASE、Hibernate-5.2.2 Final 和 Oracle 10G(数据库)。我的数据库中有一个 STUDENT 表，有 4-5 个条目。另外，我使用简单的(控制台基础)java 项目 编写了spring 代码，并且不使用任何构建工具。 这里是我当前正在使用的完整代码和库列表:

Student.java

public class Student {

    private Integer rollNo;
    private String name;
    /**
     * @param rollNo
     * @param name
     */
    public Student(Integer rollNo, String name) {
        super();
        this.rollNo = rollNo;
        this.name = name;
    }

//Getter and setter ....

StudentDAO.java

public class StudentDAO {

    private HibernateTemplate hibernateTemplate;

    public StudentDAO(HibernateTemplate hibernateTemplate) {
        this.hibernateTemplate = hibernateTemplate;

    }

    public void setHibernateTemplate(HibernateTemplate template) {
        this.hibernateTemplate = template;
    }

    public void saveStudent(Student student) {
        hibernateTemplate.save(student);
    }

    public List<Student> readAll() {
        return hibernateTemplate.loadAll(Student.class);
    }
}

我使用基于java注释的配置，所以我的AppConfig.java是:

@Configuration
public class AppConfig {

    @Bean
    public DriverManagerDataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource("jdbc:oracle:thin:@localhost:1521/xe", "user", "password");
        dataSource.setDriverClassName("oracle.jdbc.driver.OracleDriver");
        return dataSource;
    }

    @Bean 
    public LocalSessionFactoryBean sessionFactoryBean() {
        LocalSessionFactoryBean bean = new LocalSessionFactoryBean();
        bean.setDataSource(dataSource());
        bean.setMappingResources("xml/student.hbm.xml");
        Properties prop = new Properties();
        prop.setProperty("hibernate.dialect", "org.hibernate.dialect.Oracle9Dialect");
        prop.setProperty("hibernate.hbm2ddl.auto", "update");
        prop.setProperty("hibernate.show_sql", "true");
        bean.setHibernateProperties(prop);
        return bean;
    }

    @Bean
    public HibernateTemplate hibernateTemplate() {
        HibernateTemplate template = new HibernateTemplate((SessionFactory) sessionFactoryBean());
        return template;
    }

    @Bean
    public StudentDAO DAO() {
        return new StudentDAO(hibernateTemplate());
    }

}

Student.hbm.xml XML 文件:

<?xml version='1.0' encoding='UTF-8'?>  
<!DOCTYPE hibernate-mapping PUBLIC  
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"  
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
                <class name="bean.Student" table="student">
                                <rollNo name="rollNo">
                                                <generator class="assigned"></generator>
                                </rollNo>
                                <property name="name"></property>
                </class>

</hibernate-mapping>

这是我的主要方法类

public class Test {

    public static void main(String[] args) {
            ApplicationContext context = new AnnotationConfigApplicationContext(AppConfig.class);
            StudentDAO dao = context.getBean(StudentDAO.class);
            List<Student> list = dao.readAll();
            for(Student s: list) 
                System.out.println(s);
    }

}

这是我已包含在项目中的库列表(带有 jar 文件):

Spring

hibernate

Commons 日志记录和ORALCE 10G 驱动程序

还有一些其他

如何解决上述异常，我必须添加/删除哪个库或者我还可以尝试解决什么问题。后悔问了这么长的问题

示例引用
此示例基于源代码，可从 javapoint 获取。

最佳答案

我对我的示例做了一些轻微的更改。我使用了 ApplicationContext.xml，而不是 AppConfig.java。这是文件代码

                                                </props>

                </bean>

                <bean id="d" class="bean.dao.StudentDao">

                </bean>
</beans>

并添加了两个更多 jar 文件:

>commons-dbcp2-2.1.1.jar
>commons-pool2-2.4.2.jar

对于BasicDataSource类。

现在它给了我异常:

但是我偷看了hibernate-core-5.2.2-Final.jar，它在org.hibernate中定义了SessionFectory.class > 包，即有一个名为 org.hibernate.SessionFactory.class 的类条目。现在我想知道为什么它会给出这样的异常(exception)

更新经过多次尝试并在 google 上搜索，我发现 hibernate 5 不支持 oracle10g 驱动程序。所以我已将 ojdbc14.jar 更新为 ojdbc6.jar，它对我有用
