使用HibernateTemplate时发生java.lang.NoClassDefFoundError [英] java.lang.NoClassDefFoundError while using HibernateTemplate

问题描述

我试图了解Spring-Hibernate环境中HibernateTemplate的工作。由于我是HibernateTemplate的新手，我很难理解这些错误。在我的项目中，我使用了 spring-framework-4.0.3 和 hibernate-4.3.5 中的所有jar文件。这个项目中使用的一些额外的jar包括：

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

使用以下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; 
 
公共类StudentDaoImplHT实现StudentDaoInterface {

 public void setHt（HibernateTemplate ht）{
 this.ht = ht; 
 
 
 @Override 
 public int save（Student st）{
 int i =（Integer）ht.save（st）; 
返回i; 
} 
 
 @Override 
 public boolean update（Student st）{
 ht.update（st）; 
返回true; 
 
 
 @Override 
 public boolean delete（Student st）{
 ht.delete（st）;

 return st; 
}

 List list = ht.find（from student）; 
返回列表; 
} 
 
 @覆盖

解决方案

您应该使用 org.springframework.orm.hibernate4.LocalSessionFactoryBean 而不是 org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean 。但在它指出以下内容，所以要小心你的Spring版本或者将你的Hibernate从4.3.5中减少。到4.2或4.1，如文档建议。

LocalSessionFactoryBean的这种变体需要Hibernate 4.0或更高版本。请注意，这个版本与（重构的）Hibernate 4.3不兼容;请升级到 Spring 4.0版本以获得完整的Hibernate 4.3支持。我们建议在最新的Hibernate 4.1.x或4.2.x 版本中使用此版本。

I was trying to understand the working of HibernateTemplate in Spring-hibernate environment. Since I am new to HibernateTemplate, I feel difficult to understand the errors. In my project I have used all the jar files availabe in spring-framework-4.0.3 and hibernate-4.3.5. Some of the additional jars used in this project are:

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

Following java/xml files were used :

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;
    }

}

    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;
    }

解决方案

You should use org.springframework.orm.hibernate4.LocalSessionFactoryBean instead of org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean. But in doc, it says that the following, so be careful about your Spring version or decrease your Hibernate from 4.3.5. to 4.2 or 4.1 as documentation suggests.

This variant of LocalSessionFactoryBean requires Hibernate 4.0 or higher. Note that this version is not compatible with the (the quite refactored) Hibernate 4.3 yet; please upgrade to the Spring 4.0 line for full Hibernate 4.3 support. We recommend using this version with the latest Hibernate 4.1.x or 4.2.x releases.
