struts2+hibernate3+spring3（ssh2)框架下的web应用
是骡子是马，跑两步就知道了，所以先写个程序跑起来再说。首先建立个空的数据库在MySql里面，名字叫sbpms，然后建立一个表叫User，表有id，用户名，密码，角色，上级，邮箱。所以如下操作。
再插入一条数据INSERT INTO `user` VALUES (1,'ROOT',123','[email protected]',0,0);
然后在Eclipse的WebContent下WEB-PAGE根目录下创建两个jsp页面。Login.jsp和Test.jsp
Login.jsp内容为
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <%@ taglib prefix="s" uri="/struts-tags"%> <html> <head> <title>Login</title> </head> <body id="login"> <center> <s:actionerror id="actionError"/> </center> <s:form action="login"> <s:textfield name="user.name" label="name"></s:textfield> <s:password name="user.password" label="password"></s:password> <s:submit></s:submit> </s:form> </body> </html>
Test.jsp内容为
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Test</title> </head> <body> Test </body> </html>
然后在src的action中添加
ManageUserAction
.java
内容为
package com.sbpms.action;
import com.opensymphony.xwork2.ActionSupport;
import com.sbpms.bean.User;
import com.sbpms.service.UserService;
/**
* This action is used to validate and deal with login processing
* @author IanLi
*
*/
@SuppressWarnings("serial")
public class ManageUserAction extends ActionSupport {
private UserService service;
private User user;
public UserService getService() {
return service;
}
public void setService(UserService service) {
this.service = service;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
/*
* This method is used to the login JSP, include the operations of call
* database and do validation.
*/
public String login() throws Exception {
switch (this.user.getRole()) {
case 0:
return SUCCESS;
case 1:
return SUCCESS;
case 2:
return SUCCESS;
case 3:
return SUCCESS;
case 4:
return SUCCESS;
default:
return INPUT;
}
}
public void validateLogin() {
this.clearActionErrors();
if (null == this.user) {
this.addActionError("User name must not be empty");
return;
}
// Judge the the name input by whether it is empty.
if (this.user.getName() == "" || null == this.user.getName()) {
this.addActionError("User name must not be empty");
} else {
System.out.println(this.user.toString());
// Judge the password input by whether it it empty.
if (this.user.getPassword().isEmpty()
||null == this.user.getPassword()) {
this.addActionError("Password must not be empty");
} else {
// Judge the input name and password by whether they are accord
// with the database.
this.user = this.service.login(this.user);
if (null == this.user) {
this.addActionError("User name or Password error");
this.user = null;
} else {
}
}
}
}
}
在com.sbpms.bean中添加User.java和User.hbm.xml文件
User.java为
package com.sbpms.bean;
/**
*Bean for save the user
*
* @author IanLi
*/
public class User {
private String pre_password;
private Integer id;
private String name;
private String password;
private String e_mail;
private int role;
private int report_to;
public String getPre_password() {
return pre_password;
}
public void setPre_password(String pre_password) {
this.pre_password = pre_password;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getE_mail() {
return e_mail;
}
public void setE_mail(String e_mail) {
this.e_mail = e_mail;
}
public int getRole() {
return role;
}
public void setRole(int role) {
this.role = role;
}
public int getReport_to() {
return report_to;
}
public void setReport_to(int report_to) {
this.report_to = report_to;
}
@Override
public String toString()
{
return name+" "+password;
}
}
User.hbm.xml为
<?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="com.sbpms.bean"> <!-- <generator class="increment"/> --> <class name="User" table="user"> <id name="id" column="id" type="java.lang.Integer"> <generator class="increment"></generator> </id> <property name="name" column="name" type="java.lang.String"></property> <property name="password" column="password" type="java.lang.String"></property> <property name="e_mail" column="e_mail" type="java.lang.String"></property> <property name="role" column="role" type="java.lang.Integer"></property> <property name="report_to" column="report_to" type="java.lang.Integer"></property> </class> </hibernate-mapping>
接着开始写业务逻辑层
我将dao层和service层都用接口申明，然后在其impl子文件夹下实现。这样使得项目具有更好的扩展性。
下面是com.sbpms.dao下面建立UserDao.java，内容为
package com.sbpms.dao;
import com.sbpms.bean.User;
/**
* Define the interface of User DAO
*
* @author IanLi
*/
public interface UserDao {
/**
* Get the information of the user
*
* @param user
* the user with information of name and password
* @return the detail information of the user ligin
*/
public User selectUser(User user);
}
com.sbpms.dao.impl下建立UserDaoImpl.java内容为
package com.sbpms.dao.impl;
import java.util.List;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import com.sbpms.bean.User;
import com.sbpms.dao.UserDao;
/**
* The implements for User DAO interface
*
* @author IanLi
*/
public class UserDaoImpl extends HibernateDaoSupport implements UserDao {
/*
* Search the user from database and judge whether it is correct.
*
* @see
* com.augmentum.ian.ihds.dao.UserDao#searchUser(com.augmentum.ian.ihds.
* bean.User)
*/
@SuppressWarnings("unchecked")
@Override
public User selectUser(User user) {
String sqlString = "from User user where user.name=?";
String name = user.getName();
List<User> userList = this.getHibernateTemplate().find(sqlString,
name);
if (userList.size() != 0) {
// If the database return more than one user by the name, We only
// get the first one. In fact this is a wrong database.
User userR = userList.get(0);
// Judge the name and the password between the input and which get
// from database.
if (userR.getName().equals(user.getName())
&& userR.getPassword().equals(user.getPassword())) {
return userR;
}
return null;
}
return null;
}
}
com.sbpms.service下建立UserService.java,内容为
package com.sbpms.service;
import com.sbpms.bean.User;
/**
* Define the interface for the User DAO
*
* @author IanLi
*/
public interface UserService {
/**
* Used to get message of who login
*
* @param user
* the information of the name and password that who login
* @return the detail information of user who login
*/
public User login(User user);
}
com.sbpms.service.impl下建立UserServiceImpl.java内容为
package com.sbpms.service.impl;
import com.sbpms.bean.User;
import com.sbpms.dao.UserDao;
import com.sbpms.service.UserService;
/**
*The implement of user service. Accomplish most business logic here
*
* @author IanLi
*/
public class UserServiceImpl implements UserService {
private UserDao userDao;
private User newUserForService;
public UserDao getUserDao() {
return userDao;
}
public void setUserDao(UserDao userDao) {
this.userDao = userDao;
}
public User getNewUserForService() {
return newUserForService;
}
public void setNewUserForService(User newUserForService) {
this.newUserForService = newUserForService;
}
/*
* Get message of user who login
*/
@Override
public User login(User user) {
return userDao.selectUser(user);
}
}
搞定，然后在Login.jsp上面点右键，run on service。得到输入界面，输入刚才插入的用户名root和密码123，得到成功的界面Test。如果输出错误，得到错误提示。
这样，第一个程序就运行起来了，成功的链接了数据库并进行了查询操作和页面错误提示。
完整的源代码我放在爱问上面，地址将在审核通过后给出。
