hibernate - j2eeでのハイバネートアノテーションカード操作

Question

私はあなたの提案をすべて見ましたが、誰も私を助けてくれませんでした。休止状態の注釈でのj2eeカード操作の間違いを解決してください。休止状態の注釈で私の問題を解決するのを手伝ってください

これは私のpojoクラスです

package com.pojo1;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name="csl_employee")
public class Student {


    @Id
    @Column(name="ID")
    @GeneratedValue(strategy=GenerationType.AUTO)
    private int id;

    @Column(name="fname")
    private String fname;

    @Column(name="lname")
    private String lname;
    @Column(name="add")
    private String add;

    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getFname() {
        return fname;
    }
    public void setFname(String fname) {
        this.fname = fname;
    }
    public String getLname() {
        return lname;
    }
    public void setLname(String lname) {
        this.lname = lname;
    }
    public String getAdd() {
        return add;
    }
    public void setAdd(String add) {
        this.add = add;
    }


}


this is my Jsp File

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<td><input type="text" name="add"></td>

<tr>

</tr>
</table>
</form>
</body>
</html>


this is my servlet

package com.pojo1;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * Servlet implementation class Studentdemoservlet
 */
public class Studentdemoservlet extends HttpServlet {
    private static final long serialVersionUID = 1L;

    /**
     * @see HttpServlet#HttpServlet()
     */
    public Studentdemoservlet() {
        super();
        // TODO Auto-generated constructor stub
    }

    /**
     * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String fname=request.getParameter("fname");
        String lname=request.getParameter("lname");
        String add=request.getParameter("add");


        Student student=new Student();

        student.setFname(fname);
        student.setLname(lname);
        student.setAdd(add);

        CreateStudent.intercourse(student);



    }

    /**
     * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        doGet(request, response);
    }

}

this is my Insert method for student in hibernate

package com.pojo1;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;

public class CreateStudent {

    public static void intercourse(Student student) {

        SessionFactory sessionFactory;


        sessionFactory=Util.getSessionFactory();

        Session session=sessionFactory.openSession();

        Transaction t=session.beginTransaction();

        session.save(student);

        t.commit();

        session.close();

        sessionFactory.close();



    }

}


this is my Util Class

package com.pojo1;

import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;

public class Util {

    private static final SessionFactory sessionFactory;
    static
    {
        try
        {
            sessionFactory=new AnnotationConfiguration().configure().buildSessionFactory();
        }
        catch(Throwable th){
            throw new ExceptionInInitializerError(th);

        }
    }
    public static SessionFactory getSessionFactory(){
        return sessionFactory;

    }

}

this is my configuration file

<?xml version="1.0" encoding="UTF-8"?>

セッションファクトリ構成にクラスをリストする必要があるため、これはまったく機能しません。

ハイバネートとスプリングで注釈を使用するには、使用する必要がありますAnnotationSessionFactoryBean

 <bean id="sessionFactory"
    class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="annotatedClasses">
        <list>
            <value>com.pojo1</value>
        </list>
    </property>
    ....
 </bean>

または、Spring を使用していない場合は、persistence.xmlファイルで yoyr エンティティクラスを宣言することにより、セッションファクトリ構成でクラスを一覧表示できます。

<persistence ...>
    <persistence-unit ...>

        <class>com.pojo1</class>
        <class>com.pojo2</class>

    </persistence-unit>
</persistence>

これがあなたの問題を解決することを願っています
