Question

我试图了解Spring-hibernate环境中HibernateTemplate的工作原理。由于我是HibernateTemplate的新手，我觉得很难理解错误。在我的项目中，我使用了 spring-framework-4.0.3 和 hibernate-4.3.5 中提供的所有jar文件。该项目中使用的一些额外的罐子是：

*cglib-nodep-2.1.3.jar
*commons-logging.jar
*ojdbc14.jar
*tomcat-dbcp-7.0.30.jar

使用了以下java / xml文件：

StudentDaoInterface.java

package dao;

import java.util.List;

import model.Student;

public interface StudentDaoInterface {

    public int save(Student st);
    public boolean update(Student st);
    public boolean delete(Student st);
    public Student findbyPK(int pk);
    public List<Student> findAllUsingHQL();
    public List<Student> findAllUsingCriteria();

}

StudentDaoImplHT.java

package dao;

import java.util.List;

import org.hibernate.criterion.DetachedCriteria;
import org.springframework.orm.hibernate4.HibernateTemplate;

import model.Student;

public class StudentDaoImplHT implements StudentDaoInterface {

    private HibernateTemplate ht;

    public void setHt(HibernateTemplate ht) {
        this.ht = ht;
    }

    @Override
    public int save(Student st) {
        int i=(Integer)ht.save(st);
        return i;
    }

    @Override
    public boolean update(Student st) {
        ht.update(st);
        return true;
    }

    @Override
    public boolean delete(Student st) {
        ht.delete(st);
        return true;
    }

    @Override
    public Student findbyPK(int pk) {
        Student st = (Student)ht.get(Student.class,pk);
        return st;
    }

    @Override
    public List<Student> findAllUsingHQL() {
        List list = ht.find("from student"); 
        return list;
    }

    @Override
    public List<Student> findAllUsingCriteria() {
        DetachedCriteria dc = DetachedCriteria.forClass(Student.class);
        List list = ht.findByCriteria(dc);
        return list;
    }

}

Student.java

package model;

import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name="student",schema="system")
public class Student {

    @Id
    private int id;
    private String name;
    private String email;
    private String address;

    public Student(int id, String name, String email, String address) {
        super();
        this.id = id;
        this.name = name;
        this.email = email;
        this.address = address;
    }

    public void setId(int id) {
        this.id = id;
    }

    public void setName(String name) {
        this.name = name;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public void setAddress(String address) {
        this.address = address;
    }

}

的test.xml

SaveClient.java

package test;

import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import dao.StudentDaoInterface;
import model.Student;

public class SaveClient {


    public static void main(String[] args){
        ConfigurableApplicationContext cap = new ClassPathXmlApplicationContext("resources/test.xml");
        StudentDaoInterface dao = (StudentDaoInterface)cap.getBean("dao");
        Student st = new Student(222,"bbb","bbb@gmail.com","hyd");      
        dao.save(st);
        System.out.println("success");
        cap.close();
    }


}

运行代码 SaveClient.java 后，我面临以下错误：

您应该使用org.springframework.orm.hibernate4.LocalSessionFactoryBean代替org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean。但在doc中，它表示如下，所以要小心你的Spring版本或从4.3.5减少你的Hibernate。如文件所示，为4.2或4.1。

LocalSessionFactoryBean的这个变体需要Hibernate 4.0或更高版本。请注意，此版本与（经过重构的）Hibernate 4.3不兼容;请升级到 Spring 4.0系列以获得完整的Hibernate 4.3支持。我们建议将此版本与最新的Hibernate 4.1.x或4.2.x 版本一起使用。

使用HibernateTemplate时的java.lang.NoClassDefFoundError
