篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了SpringMVC+Spring+hibernate整合及分页相关的知识，希望对你有一定的参考价值。

1. 新建web project

2. 引入jar,

3. 创建包com.tgb.web.controller，下面创建包（dao，entity，service， config，spring，hibernate）

config-> spring-core.xml,spring-servlet.xml,spring-hibernate.xml

1) config下 springmvc配置文件 spring-servlet.xml

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

hibernate->hibernate.cfg.xml

<?xml version=‘1.0‘ encoding=‘utf-8‘?>
<!DOCTYPE hibernate-configuration PUBLIC

    <url-pattern>/*</url-pattern>  
  </filter-mapping>

4. 建实体类　

entity->User.java

package com.tgb.web.controller.entity;

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


@Entity
@Table(name="T_USER")
public class User {
	@Id
	@GeneratedValue
	@Column(length=32)
	private Long id;

	public Long getId() {
		return id;
	}
	public void setId(Long id) {
		this.id = id;
	}
	@Column(length=32)
	private String userName;
	@Column(length=32)
	private String age;
	public String getUserName() {
		return userName;
	}
	public void setUserName(String userName) {
		this.userName = userName;
	}
	public String getAge() {
		return age;
	}
	public void setAge(String age) {
		this.age = age;
	}
}

5. 建DAO层　

dao->IUserDao.java, UserDao.java

1) IUserDao.java接口文件

package com.tgb.web.controller.dao;
import java.util.List;
import com.tgb.web.controller.entity.User;
public interface IUserDAO {
	public void addUser(User user);
	public List<User> getAllUser();
	public boolean delUser(Long id);
	public User getUser(Long id);
	public boolean updateUser(User user);
	public List<User> getForPage(int offset, int length);
	public Long getAllRowCount();
}

　　2) UserDao.java 实体类

package com.tgb.web.controller.dao;
import java.util.List;
import org.hibernate.Query;
import org.hibernate.SessionFactory;

import com.tgb.web.controller.entity.User;

public class UserDAO implements IUserDAO {

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

	public void setSessionFactory(SessionFactory sessionFactory) {
		this.sessionFactory = sessionFactory;
	}

	@Override
	public void addUser(User user) {
		sessionFactory.getCurrentSession().save(user);
	}

	@Override
	public List<User> getAllUser() {
		String hql = "FROM User";
		Query query =  sessionFactory.getCurrentSession().createQuery(hql);
		return query.list();
	}


	@Override
	public boolean delUser(Long id) {
		String hql = "DELETE User u WHERE u.id=?";
		Query query =  sessionFactory.getCurrentSession().createQuery(hql);
		query.setString(0, String.valueOf(id));
		
		return (query.executeUpdate()>0);
	}

	@Override
	public User getUser(Long id) {
		String hql = "FROM User u WHERE u.id=?";
		Query query =  sessionFactory.getCurrentSession().createQuery(hql);
		query.setString(0, String.valueOf(id));
		return (User)query.uniqueResult();
	}

	@Override
	public boolean updateUser(User user) {
		String hql = "UPDATE User u SET u.userName=? ,u.age=? WHERE u.id=?";
		Query query =  sessionFactory.getCurrentSession().createQuery(hql);
		query.setString(0, String.valueOf(user.getUserName()));
		query.setString(1, String.valueOf(user.getAge()));
		query.setString(2, String.valueOf(user.getId()));
		
		return (query.executeUpdate()>0);
	}

	@Override
	public List<User> getForPage(int offset, int length) {
		List<User> userList=null;
		String hql = "FROM User";
		Query query =  sessionFactory.getCurrentSession().createQuery(hql);
		query.setFirstResult(offset);
        query.setMaxResults(length);
        userList=query.list();
        return userList;	      
	}

	@Override
	public Long getAllRowCount() {
		String hql = "SELECT COUNT(*) FROM User";
		Query query = sessionFactory.getCurrentSession().createQuery(hql);
		return Long.parseLong(query.uniqueResult().toString());
	}

}

6. 建service层

service->IUserManager.java, UserManager.java

1) IUserManager.java接口

package com.tgb.web.controller.service;

import java.util.List;

import com.tgb.web.controller.entity.Page;
import com.tgb.web.controller.entity.User;

public interface IUserManager {
	public void addUser(User user);
	public List<User> getAllUser();
	public boolean delUser(Long id);
	public User getUser(Long id);
	public boolean updateUser(User user);
	public Page getForPage(int offset, int length);
	public Long getAllRowCount();
}

　2) UserManager.java实现类

package com.tgb.web.controller.service;

import java.util.List;

import com.tgb.web.controller.dao.IUserDAO;
import com.tgb.web.controller.entity.Page;
import com.tgb.web.controller.entity.User;

public class UserManager implements IUserManager{
	private IUserDAO userDao;
	
	public IUserDAO getUserDao() {
		return userDao;
	}

	public void setUserDao(IUserDAO userDao) {
		this.userDao = userDao;
	}

	@Override
	public void addUser(User user) {
		userDao.addUser(user);		
	}

	@Override
	public List<User> getAllUser() {
		return userDao.getAllUser();
	}

	@Override
	public boolean delUser(Long id) {
		return userDao.delUser(id);
	}

	@Override
	public User getUser(Long id) {
		return userDao.getUser(id);
	}

	@Override
	public boolean updateUser(User user) {
		return userDao.updateUser(user);
	}

	@Override
	public Page getForPage(int currentPage, int pageSize) {
		Page page = new Page();
		int allRow = userDao.getAllRowCount().intValue();
		int offset = page.countOffset(currentPage, pageSize);
		List<User> list= userDao.getForPage(offset, pageSize);
		page.setPageNo(currentPage);
		page.setPageSize(pageSize);
		page.setTotalRecords(allRow);
		page.setList(list);
		return page;
	}

	@Override
	public Long getAllRowCount() {
		return userDao.getAllRowCount();
	}
}

7. 建controller

　controller包下新建controller文件

UserController.java

package com.tgb.web.controller;

import java.io.IOException;
import java.io.PrintWriter;
import java.util.List;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.tgb.web.controller.entity.Page;
import com.tgb.web.controller.entity.User;
import com.tgb.web.controller.service.IUserManager;

@Controller
@RequestMapping("/user")
public class UserController {
	@Resource(name="userManager")
	private IUserManager userManager;
	
	@RequestMapping("/addUser")
	public String addUser(User user){
		userManager.addUser(user);
		return "redirect:/user/getAllUsers";
	}
	@RequestMapping("/toAddUser")
	public String toAddUser(){
		return "/addUser";
	}
	
	@RequestMapping("/delUser")
	public void delUser(Long id,HttpServletResponse response){
		String result = "{\"result\":\"error\"}";
		if(userManager.delUser(id)){
			result = "{\"result\":\"success\"}";
		}
		PrintWriter out = null;
	    response.setContentType("application/json");
	    try {
	    	out=response.getWriter();
	        out.write(result);
	    } catch (IOException e) {
	        e.printStackTrace();
	    }
	}
	
	@RequestMapping("/getAllUser")
	public String getAllUser(HttpServletRequest request){
		List<User> users = userManager.getAllUser();
		request.setAttribute("users", users);
		return "/userManager";
	}
	
	@RequestMapping("/getAllUsers")
	public String getAllUsers(HttpServletRequest request){
		 try {
	            String pageNo = request.getParameter("pageNo");
	            if (pageNo == null) {
	                pageNo = "1";
	            }
	            Page page = userManager.getForPage(Integer.valueOf(pageNo), 10);
	            request.setAttribute("page", page);
	            List<User> pageusers = page.getList();
	            request.setAttribute("pageusers", pageusers);
	        } catch (Exception e) {
	            e.printStackTrace();
	        }
		return "/userManagerPage";
	}
	
	@RequestMapping("/getUser")
	public String getUser(Long id,HttpServletRequest request){
		User user = userManager.getUser(id);
		request.setAttribute("user", user);
		return "/editUser";
	}
	
	@RequestMapping("/updateUser")
	public String updateUser(User user,HttpServletRequest request, HttpServletResponse response){
		if(userManager.updateUser(user)){
			return "redirect:/user/getAllUsers";
		}
		else{
			return "error";
		}
		
	
	}
	
}

8. 建显示层jsp文件　　

userManager.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

	   }	 
    </script>

IE端访问:

http://localhost:8080/springMVCSSH2/user/getAllUser

分页的话, 在entity里新建Page.java

package com.tgb.web.controller.entity;
import java.util.List;

public class Page<E> {
    // 结果集
    private List<E> list;

    // 查询记录总数
    private int totalRecords;

    // 每页多少条记录
    private int pageSize;

    // 第几页
    private int pageNo;
    
    /**
     * @return 总页数
     * */
    public int getTotalPages(){
        return (totalRecords+pageSize-1)/pageSize;
    }
    
    /**
     * 计算当前页开始记录
     * @param pageSize 每页记录数
     * @param currentPage 当前第几页
     * @return 当前页开始记录号
     */
    public int countOffset(int currentPage,int pageSize){
        int offset = pageSize*(currentPage-1);
        return offset;
    }
    
    /**
     * @return 首页
     * */
    public int getTopPageNo(){
        return 1;
    }
    
    /**
     * @return 上一页
     * */
    public int getPreviousPageNo(){
        if(pageNo<=1){
            return 1;
        }
        return pageNo-1;
    }
    
    /**
     * @return 下一页
     * */
    public int getNextPageNo(){
        if(pageNo>=getBottomPageNo()){
            return getBottomPageNo();
        }
        return pageNo+1;
    }
    
    /**
     * @return 尾页
     * */
    public int getBottomPageNo(){
        return getTotalPages();
    }
    
    
    public List<E> getList() {
        return list;
    }

    public void setList(List<E> list) {
        this.list = list;
    }

    public int getTotalRecords() {
        return totalRecords;
    }

    public void setTotalRecords(int totalRecords) {
        this.totalRecords = totalRecords;
    }

    public int getPageSize() {
        return pageSize;
    }

    public void setPageSize(int pageSize) {
        this.pageSize = pageSize;
    }

    public int getPageNo() {
        return pageNo;
    }

    public void setPageNo(int pageNo) {
        this.pageNo = pageNo;
    }

}

在UserDao.java里加入新方法

@Override
	public List<User> getForPage(int offset, int length) {
		List<User> userList=null;
		String hql = "FROM User";
		Query query =  sessionFactory.getCurrentSession().createQuery(hql);
		query.setFirstResult(offset);
        query.setMaxResults(length);
        userList=query.list();
        return userList;	      
	}

	@Override
	public Long getAllRowCount() {
		String hql = "SELECT COUNT(*) FROM User";
		Query query = sessionFactory.getCurrentSession().createQuery(hql);
		return Long.parseLong(query.uniqueResult().toString());
	}

UserManage.java里调用dao方法

@Override
	public Page getForPage(int currentPage, int pageSize) {
		Page page = new Page();
		int allRow = userDao.getAllRowCount().intValue();
		int offset = page.countOffset(currentPage, pageSize);
		List<User> list= userDao.getForPage(offset, pageSize);
		page.setPageNo(currentPage);
		page.setPageSize(pageSize);
		page.setTotalRecords(allRow);
		page.setList(list);
		return page;
	}

	@Override
	public Long getAllRowCount() {
		return userDao.getAllRowCount();
	}

UserController里调用

@RequestMapping("/getAllUsers")
	public String getAllUsers(HttpServletRequest request){
		 try {
	            String pageNo = request.getParameter("pageNo");
	            if (pageNo == null) {
	                pageNo = "1";
	            }
	            Page page = userManager.getForPage(Integer.valueOf(pageNo), 10);
	            request.setAttribute("page", page);
	            List<User> pageusers = page.getList();
	            request.setAttribute("pageusers", pageusers);
	        } catch (Exception e) {
	            e.printStackTrace();
	        }
		return "/userManagerPage";
	}

　　新建显示层jsp文件 UserManagerPage.jsp
