SpringMVC+Spring3+Hibernate4框架搭建（3）
首先用自动生成的那个页面，index.jsp：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<body>
<h2>Hello World!</h2>
<a href="save.m">保存</a>
<a href="update.m">更新</a>
<a href="delete.m">删除</a>
<a href="get.m">查询</a>
<h1>操作结果：</h1>
<h2>${result}</h2>
</body>
</html>
编写一个简单的实体类，
SimpleBean：
package simples.bean;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
@Entity
public class SimpleBean {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column
private Long id;
@Column
private String name;
@Column
private String remark;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getRemark() {
return remark;
}
public void setRemark(String remark) {
this.remark = remark;
}
@Override
public String toString() {
return "SimpleBean [id=" + id + ", name=" + name + ", remark=" + remark
+ "]";
}
}
再编写一个Controller，
SimpleController：
package simples.web;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import simples.bean.SimpleBean;
import simples.service.SimpleService;
@Controller
public class SimpleController {
@Autowired
private SimpleService simpleService;
@RequestMapping("/save")
public String save(ModelMap modelMap){
System.out.println("SimpleController.save()");
SimpleBean bean = new SimpleBean();
bean.setName("bean111");
bean.setRemark("bean1");
simpleService.save(bean);
modelMap.addAttribute("result", "保存成功");
return "index";
}
@RequestMapping("/update")
public String update(ModelMap modelMap){
System.out.println("SimpleController.update()");
SimpleBean bean = simpleService.get(1L);
bean.setName("simple1");
bean.setRemark("simple2");
simpleService.update(bean);
modelMap.addAttribute("result", "更新成功");
return "index";
}
@RequestMapping("/delete")
public String delete(ModelMap modelMap){
System.out.println("SimpleController.delete()");
simpleService.delete(1L);
modelMap.addAttribute("result", "删除成功");
return "index";
}
@RequestMapping("/get")
public String get(ModelMap modelMap){
System.out.println("SimpleController.get()");
SimpleBean bean = simpleService.get(1L);
modelMap.addAttribute("result", bean);
return "index";
}
}
service的接口，
SimpleService：
package simples.service;
import simples.bean.SimpleBean;
public interface SimpleService {
void save(SimpleBean bean);
void update(SimpleBean bean);
void delete(Long id);
SimpleBean get(Long id);
}
service的实现类，
SimpleServiceImpl：
package simples.service.impl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import simples.bean.SimpleBean;
import simples.dao.SimpleDao;
import simples.service.SimpleService;
@Service
public class SimpleServiceImpl implements SimpleService {
@Autowired
private SimpleDao simpleDao;
public void save(SimpleBean bean) {
simpleDao.save(bean);
}
public void update(SimpleBean bean) {
simpleDao.update(bean);
}
public void delete(Long id) {
simpleDao.delete(id);
}
public SimpleBean get(Long id) {
return simpleDao.get(id);
}
}
Dao的接口，
SimpleDao：
package simples.dao;
import simples.bean.SimpleBean;
public interface SimpleDao {
void save(SimpleBean bean);
void update(SimpleBean bean);
void delete(Long id);
SimpleBean get(Long id);
}
Dao的实现类，
SimpleDaoImpl：
package simples.dao.impl;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import simples.bean.SimpleBean;
import simples.dao.SimpleDao;
@Repository
public class SimpleDaoImpl implements SimpleDao {
@Autowired
private SessionFactory sessionFactory;
private Session getSession() {
return sessionFactory.getCurrentSession();
}
public void save(SimpleBean bean) {
getSession().save(bean);
}
public void update(SimpleBean bean) {
getSession().update(bean);
}
public void delete(Long id) {
Session session = getSession();
Object bean = session.get(SimpleBean.class, id);
session.delete(bean);
}
public SimpleBean get(Long id) {
return (SimpleBean) getSession().get(SimpleBean.class, id);
}
}
下面演示最基本的功能，打开index.jsp页面后应该是这个页面：
点击保存后：
再点击查询：
到这里，SpringMVC+Spring3+Hibernate4框架的搭建就完成了，剩下2个功能可以自己测试。
