Question

我已经阅读了许多与此错误相关的帖子，并且不明白为什么我连续收到此错误，即使我在相同版本的类路径中都有所有jar。

我在没有Maven的情况下使用Spring 3.2.9，Hibernate，Tomcat，Java7和Eclipse Juno。

我还在学习Spring MVC并且不太清楚这个错误是如何解决的。

    package com.test.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import com.anil.bean.Student;
import com.test.service.StudentService;


@Controller
public class StudentController {

@Autowired
private StudentService studentservice;
public void setStudentservice(StudentService studentservice) {
    this.studentservice = studentservice;
}

@RequestMapping(value = "/", method = RequestMethod.GET)
public String listStudent(ModelMap map){
    map.addAttribute("student", new Student());
    map.addAttribute("studentList", studentservice.getstudentlist());
    return "index";
}

@RequestMapping(value = "/add", method = RequestMethod.POST)
public String addStudent(@ModelAttribute(value="student") Student student, BindingResult result){
studentservice.addstudent(student);
return "redirect:/";
}
@RequestMapping(value = "/delete/{age}")
public String deleteStudent(@PathVariable("age") Integer age){
    studentservice.deletestudent(age);
    return "redirect:/";
}
}

DAO实施

    package com.test.dao;

import java.util.List;

import org.hibernate.SessionFactory;
import org.springframework.stereotype.Repository;

import com.anil.bean.Student;

@Repository
public class StudentDAOimpl implements StudentDAO{

    private SessionFactory sessionFactory;
    @Override
    public void addstudent(Student student) {
        this.sessionFactory.getCurrentSession().save(student);
    }

    @SuppressWarnings("unchecked")
    @Override
    public List<Student> getstudentlist() {
        return this.sessionFactory.getCurrentSession().createQuery("from Student").list();
    }

    @Override
    public void deletestudent(Integer age) {
        Student student = (Student) sessionFactory.getCurrentSession().load(Student.class, age);
        if(null != student)
        this.sessionFactory.getCurrentSession().delete(student);
    }

}

服务类

    package com.test.service;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.anil.bean.Student;
import com.test.dao.StudentDAO;

@Service
public class StudentServiceImpl implements StudentService {
    @Autowired
    private StudentDAO studentdao;

    @Override
    @Transactional
    public void addstudent(Student student) {
        studentdao.addstudent(student);
    }

    public void setStudentdao(StudentDAO studentdao) {
        this.studentdao = studentdao;
    }

    @Override
    @Transactional
    public List<Student> getstudentlist() {
        return studentdao.getstudentlist();
    }

    @Override
    @Transactional
    public void deletestudent(Integer age) {
        studentdao.deletestudent(age);
    }
