spring+springmvc+hibernate template礼品管理系统
1.简单介绍
如标题所示，这篇文章简单写了一个基于spring+springmvc+hibernate template的礼品管理系统，适合初学者，这是我的第三篇文章，希望可以通过这篇文章让同学了解这个系统基本流程，虽然逐渐退出主流，但是还有很多地方思路值得我们学习。如有兴趣，可以随时联系我：1763907618.
2.环境搭建
我的项目测试成功，前台jsp,没有美化，主要是后台功能都能实现。
jdk：1.6；
数据库：mysql5.6；
基于hibernate的jar包，cglib.jar可能还会有冲突，每次发布项目需要删除。
基于springmvc的jar包，
3.成果基本样式
4.详细内容
HibernateTemplate的常用方法。
delete(Object entity): 删除指定持久化实例。
find(String queryString): 根据 HQL 查询字符串来返回实例集合。
save(Object entity): 保存新的实例。
update(Object entity): 更新实例的状态，要求entity 是持久状态。
主要就是一个增删改查的过程。上面这四个是我们常用方法。
因为我的项目用到了hibernate的逆向工程，所以数据库是自动生成。
下面就写一个登录实例，因为登录是一个查询的过程，所以我们将用find方法。
a.创建项目，导入jar包，这些我就不介绍了。
b.创建
com.controller,
com.dao,
com.model,
com.service
包，在里面分别建立java
usercontroller,
userdao,
user,
userservice
注意开头大写。
c.编写hibernate.cfg.xml
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="connection.url">jdbc:mysql://localhost:3306/bgift?useUnicode=true&characterEncoding=UTF-8</property>
<property name="connection.username">root</property>
<property name="connection.password">1478</property>

<property name="format_sql">true</property>
<property name="hbm2ddl.auto">update</property>
<property name="hibernate.connection.autocommit">true</property>
<mapping class="com.model.User" />
/////其中 mapping class="com.model.User"是要注意的。路径问题。
</session-factory> </hibernate-configuration>
d.编写web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"

e.编写applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

f.编写com.model.user.java
package com.model; import java.util.Date; 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="user")
public class User { int id;
String username;
String password;
@Id
@Column
@GeneratedValue(strategy=GenerationType.AUTO)
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
@Column
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
@Column
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
} }
g.编写com.model.userdao.java
package com.dao; import java.util.Date;
import java.util.List; import javax.annotation.Resource; import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Repository; import com.model.User; @Repository
public class UserDao extends HibernateDaoSupport{
@Resource
public void setSessionFactoryOverride(SessionFactory sessionFactory){
super.setSessionFactory(sessionFactory);
} /////////////*登录*//////////////////////////////*登录*////////////////////////*登录*/
@SuppressWarnings("unchecked")
public List<User> userlogin(User user){
String hql= "from User where username=? and password=?";
List<User> t=this.getHibernateTemplate().find(hql,new Object[]{user.getUsername(),user.getPassword()});
return t;
} }
h.编写com.model.userservice.java
package com.service; import java.util.List; import javax.annotation.Resource;
import org.springframework.stereotype.Component; import com.dao.UserDao;
import com.model.User; @Component
public class UserService {
@Resource
UserDao userdao; public UserDao getUserdao() {
return userdao;
} public void setUserdao(UserDao userdao) {
this.userdao = userdao;
}
/////////////*登录*//////////////////////////////*登录*//////////*登录*/
public List<User> userlogin(User user){
return userdao.userlogin(user); } }
i.编写com.model.usercontroller.java
package com.Controller; import java.io.IOException;
import java.io.PrintWriter;
import java.util.List; import javax.annotation.Resource;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession; import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping; import com.model.User;
import com.service.UserService; @Controller
public class UserController {
@Resource
UserService userService; public UserService getUserService() {
return userService;
} public void setUserService(UserService userService) {
this.userService = userService;
} /////////////*登录*//////////////////////////////*登录*/
@RequestMapping("userlogin.do")
public String findAll(HttpSession session,User user,HttpServletResponse response){
List<User> listuser = userService.userlogin(user);
if(listuser.size()>0){
session.setAttribute("listuser", listuser);
return "loginsuccess";
}else{
response.setContentType("text/html; charset=UTF-8"); //转码
PrintWriter out;
try {
out = response.getWriter();
out.flush();
out.println("<script>");
out.println("alert('账号或密码错误！');");
out.println("history.back();");
out.println("</script>");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return "index";
}
} }
j.编写前台index.jsp
<form name="formuser" id="formuser" method="post" action="userlogin.do">
<input type="text" id="username" name="username" placeholder="请输入账号" /><br /><br />
<input type="password" class="index_mi" id="password" name="password" placeholder="请输入密码" /><br /><br />
<input class="index_z_fi" type="submit" value="登录" />
</form>
k.编写前台loginsuccess.jsp
添加${sessionScope.listuser[0].username}
接受后台传来的session.setAttribute("listuser", listuser);值。
5.总结
一个登录写完，其实我只是把文件中的一部分赋值过来，便于了解。
在写这个系统之前，有过很多问题：
a.路径问题，return 后面接jsp路径的话，要把路径写对，在提交时候XXX.do要写对。否则404。
b.jar包冲突问题，当初困扰我很久，后来把冲突包删除，再发布后还会出现，索性把jar包都放到lib文件夹下。
c.乱码，在web.xml下配置，相互传值要注意。比较好改。
