使用Cassanra DB的Spring-Hibernate：未找到CassandraCQL2Dialect的类

标签： java spring hibernate cassandra

我已经为Cassandra数据库编写了一个基本的示例Spring-Hibernate应用程序

1）人员-模型班

2）PersonDao-道课

3）hbm文件-用于映射

4）applicationContext.xml

5）PersonMain-主类

6）pom.xml

7）异常信息

人员模型类：-

public class Person {
    private int personId;
    private String personName;

    public int getPersonId() {
       return personId;
    }
    public void setPersonId(int personId) {
       this.personId = personId;
    }
    public String getPersonName() {
       return personName;
    }
    public void setPersonName(String personName) {
       this.personName = personName;
    }

}

PersonDao：-此类用于数据库操作

public class PersonDao {
    HibernateTemplate template;
    public void setTemplate(HibernateTemplate template){
        this.template = template;
    }
    public void savePerson(Person p){
        template.save(p);
    }
    public void updatePerson(Person p){
        template.update(p);
    }
    public void deletePerson(Person p){
        template.delete(p);
    }
    public Person getPersonById(int personId){
        return (Person)template.get(Person.class, personId);
    }
    public List<Person> getAllPersons(){
        return template.loadAll(Person.class);
    }
}

person.hbm.xml：-

PersonMain：-

public class PersonMain {

    public static void main(String[] args) {
        System.out.println("****** Spring With Hibernate *******");
        ApplicationContext context = new     ClassPathXmlApplicationContext("applicationContext.xml");
        PersonDao dao = context.getBean(PersonDao.class);
        System.out.println("****** Starting Dao Operations *******");

        Person p = new Person();
        p.setPersonId(126);
        p.setPersonName("Sathish");

        Person p2 = new Person();
        p2.setPersonId(124);
        p2.setPersonName("Sathish Kumar");
        // This statement getting executed and I am able to see record in the DB 
        dao.savePerson(p); 
        // After insertion the below print statement is not printing in console and also not executing next statements too
        // i.e after insertion closing the connection
        System.out.println("****** End of Dao Insert *******");
        List<Person> list = dao.getAllPersons();
        list.forEach(person -> {System.out.println(person);});
        System.out.println("****** End of Dao Get All *******");

        Person p1 = dao.getPersonById(123);
        System.out.println(p1);
        System.out.println("****** End of Dao Get *******");
        dao.updatePerson(p1);
        System.out.println("****** End of Dao Update *******");
        dao.deletePerson(p2);
        System.out.println("****** End of Dao Delete *******");
    }

}

异常信息：-

现在我得到java.lang.ClassNotFoundException: org.hibernate.ogm.dialect.cassandra.CassandraCQL2Dialect，为此也添加了依赖性，但仍然解决了这个问题
