struts.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
<package name="default" extends="struts-default">

<action name="doLogin" class="umAction">

<result name="error">error.jsp</result>
<result name="success">success.jsp</result>
</action>
</package>
</struts>

3.编写数据访问层
UserDAO.java

package com.ssh2test1.dao;

import java.util.List;

import com.ssh2test1.entity.Users;

public interface UserDAO {
public List search(Users condition);
}

UserDAOImpl.java
package com.ssh2test1.dao;

import java.sql.SQLException;
import java.util.List;

import org.hibernate.Criteria;
import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.criterion.Restrictions;
import org.springframework.orm.hibernate3.HibernateCallback;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.ssh2test1.entity.Users;

public class UserDAOImpl extends HibernateDaoSupport implements UserDAO {

@Override
public List search(final Users condition) {
// TODO Auto-generated method stub
return super.getHibernateTemplate().executeFind(new HibernateCallback() {

@Override
public Object doInHibernate(Session session) throws HibernateException, SQLException {
// TODO Auto-generated method stub
Criteria c=session.createCriteria(Users.class);
if(condition!=null){
if(condition.getLoginName()!=null && !condition.getLoginName().equals("")){
c.add(Restrictions.eq("loginName", condition.getLoginName()));
}
if(condition.getLoginPwd()!=null && !condition.getLoginPwd().equals("")){
c.add(Restrictions.eq("loginPwd", condition.getLoginPwd()));
}
}
return c.list();
}
});
}

}

4.编写业务逻辑层
UserBiz.java

package com.ssh2test1.biz;

import java.util.List;

import com.ssh2test1.entity.Users;

public interface UserBiz {
public List login(Users condition);
}

UserBizImpl.java
package com.ssh2test1.biz;

import java.util.List;

import com.ssh2test1.dao.UserDAO;
import com.ssh2test1.entity.Users;

public class UserBizImpl implements UserBiz {

//使用UserDAO接口声明对象，并添加set方法用于依赖注入
UserDAO userDAO;

public void setUserDAO(UserDAO userDAO){
this.userDAO=userDAO;
}
public List login(Users condition) {
// TODO Auto-generated method stub
return userDAO.search(condition);
}

}

5.编写实体类及实体映射文件
Users.java

package com.ssh2test1.entity;

import java.io.Serializable;

public class Users implements Serializable {
private Integer id;
private String loginName;
private String loginPwd;
private String name;
private String address;
private String phone;
private String mail;
private Integer userRoleId;
private Integer userStateId;
public Users() {
}
public Users(String loginName, String loginPwd, String name,
String address, String phone, String mail, Integer userRoleId,
Integer userStateId) {
this.loginName = loginName;
this.loginPwd = loginPwd;
this.name = name;
this.address = address;
this.phone = phone;
this.mail = mail;
this.userRoleId = userRoleId;
this.userStateId = userStateId;
}
public Integer getId() {
return this.id;
}

public void setId(Integer id) {
this.id = id;
}

public String getLoginName() {
return this.loginName;
}

public void setLoginName(String loginName) {
this.loginName = loginName;
}

public String getLoginPwd() {
return this.loginPwd;
}

public void setLoginPwd(String loginPwd) {
this.loginPwd = loginPwd;
}

public String getName() {
return this.name;
}

public void setName(String name) {
this.name = name;
}

public String getAddress() {
return this.address;
}

public void setAddress(String address) {
this.address = address;
}

public String getPhone() {
return this.phone;
}

public void setPhone(String phone) {
this.phone = phone;
}

public String getMail() {
return this.mail;
}

public void setMail(String mail) {
this.mail = mail;
}

public Integer getUserRoleId() {
return this.userRoleId;
}

public void setUserRoleId(Integer userRoleId) {
this.userRoleId = userRoleId;
}

public Integer getUserStateId() {
return this.userStateId;
}

public void setUserStateId(Integer userStateId) {
this.userStateId = userStateId;
}
}

Users.hbm.xml
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
<class name="com.ssh2test1.entity.Users" table="users" catalog="bookshop">
<id name="id" type="java.lang.Integer">
<column name="Id" />
<generator class="native"></generator>
</id>
<property name="loginName" type="java.lang.String">
<column name="LoginName" length="50" />
</property>
<property name="loginPwd" type="java.lang.String">
<column name="LoginPwd" length="16" />
</property>
<property name="name" type="java.lang.String">
<column name="Name" length="16" />
</property>
<property name="address" type="java.lang.String">
<column name="Address" length="16" />
</property>
<property name="phone" type="java.lang.String">
<column name="Phone" length="16" />
</property>
<property name="mail" type="java.lang.String">
<column name="Mail" length="16" />
</property>
<property name="userRoleId" type="java.lang.Integer">
<column name="UserRoleId" />
</property>
<property name="userStateId" type="java.lang.Integer">
<column name="UserStateId" />
</property>
</class>
</hibernate-mapping>

6.编写action控制类
package com.ssh2test1.action;

import java.util.List;

import com.opensymphony.xwork2.ActionSupport;
import com.ssh2test1.biz.UserBiz;
import com.ssh2test1.entity.Users;

public class UserManagerAction extends ActionSupport {
//定义用于保存用户登录表单参数的两个属性
private String loginName;
private String loginPwd;
public String getLoginName() {
return loginName;
}
public void setLoginName(String loginName) {
this.loginName = loginName;
}
public String getLoginPwd() {
return loginPwd;
}
public void setLoginPwd(String loginPwd) {
this.loginPwd = loginPwd;
}
//使用UserBiz声明一个对象，并添加set方法用于依赖注入
UserBiz userBiz;
public void setUserBiz(UserBiz userBiz) {
this.userBiz = userBiz;
}
//重载execute方法用来处理登录请求
public String execute() throws Exception {
// TODO Auto-generated method stub
Users condition=new Users();
condition.setLoginName(loginName);
condition.setLoginPwd(loginPwd);
List list=userBiz.login(condition);
if(list.size()>0){
//登录成功，转到success.jsp页面
return "success";
}else{
//登录失败，转到error.jsp页面
return "error";
}
}
}
