5. web.xml

<?xml version="1.0" encoding="UTF-8"?> 
<web-app version="2.5"    
    xmlns="http://java.sun.com/xml/ns/javaee"

6. 在src下建struts.xml

<?xml version="1.0" encoding="UTF-8" ?> 
<!DOCTYPE struts PUBLIC   
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"   
    "http://struts.apache.org/dtds/struts-2.0.dtd"> 

<struts> 
       
    <!--导入struts-default.xml文件 --> 
    <include file="struts-default.xml"></include> 
       
    <!-- 配置中文支持 --> 
    <constant name="struts.i18n.encoding" value="GBK"></constant> 
       
    <!-- 配置Action --> 
    <package name="struts" extends="struts-default" namespace="/"> 
        <action name="login" class="loginAction"> 
            <result name="success">/result.jsp</result> 
            <result name="fail">/error.jsp</result> 
        </action> 
    </package> 
       
</struts> 
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>

<!--导入struts-default.xml文件 -->
<include file="struts-default.xml"></include>

<!-- 配置中文支持 -->
<constant name="struts.i18n.encoding" value="GBK"></constant>

<!-- 配置Action -->
<package name="struts" extends="struts-default" namespace="/">
   <action name="login" class="loginAction">
    <result name="success">/result.jsp</result>
    <result name="fail">/error.jsp</result>
   </action>
</package>

</struts>

7. 创建数据表

create table `mytest`.`person`(
`id` INT default '' not null,
`uname` VARCHAR(20),
`upwd` VARCHAR(20)
);

8. 使用工具通过Person表生成类文件和Person.hbm.xml

package com.user.vo;   

public class Person implements java.io.Serializable {   

    private Integer id;   
    private String uname;   
    private String upwd;   

    public Person() {   
    }   

    public Person(Integer id) {   
        this.id = id;   
    }   
       
    public Person(Integer id, String uname, String upwd) {   
        this.id = id;   
        this.uname = uname;   
        this.upwd = upwd;   
    }   
       
    public Integer getId() {   
        return this.id;   
    }   
       
    public void setId(Integer id) {   
        this.id = id;   
    }   

    public String getUname() {   
        return this.uname;   
    }   
       
    public void setUname(String uname) {   
        this.uname = uname;   
    }   

    public String getUpwd() {   
        return this.upwd;   
    }   
       
    public void setUpwd(String upwd) {   
        this.upwd = upwd;   
    }   

} 
package com.user.vo;

public class Person implements java.io.Serializable {

    private Integer id;
    private String uname;
    private String upwd;

    public Person() {
    }

    public Person(Integer id) {
        this.id = id;
    }
    
    public Person(Integer id, String uname, String upwd) {
        this.id = id;
        this.uname = uname;
        this.upwd = upwd;
    }
    
    public Integer getId() {
        return this.id;
    }
    
    public void setId(Integer id) {
        this.id = id;
    }

    public String getUname() {
        return this.uname;
    }
    
    public void setUname(String uname) {
        this.uname = uname;
    }

    public String getUpwd() {
        return this.upwd;
    }
    
    public void setUpwd(String upwd) {
        this.upwd = upwd;
    }

}

<?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.user.vo.Person" table="person" catalog="mytest"> 
        <id name="id" type="java.lang.Integer"> 
            <column name="id" length="4" /> 
        </id> 
        <property name="uname" type="java.lang.String"> 
            <column name="uname" length="20" /> 
        </property> 
        <property name="upwd" type="java.lang.String"> 
            <column name="upwd" length="20" /> 
        </property> 
    </class> 
</hibernate-mapping> 
<?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.user.vo.Person" table="person" catalog="mytest">

   </property>
   <property name="upwd" type="java.lang.String">
    <column name="upwd" length="20" />
   </property>
</class>
</hibernate-mapping>

9. 创建业务逻辑处理类

package com.user.dao;   

import java.util.List;   

import org.hibernate.Query;   
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;   

import com.user.vo.Person;   

public class PersonManager extends HibernateDaoSupport{   
       
    public boolean isLogin(Person per){   
        boolean flag = false;   
           
        String hql = "From Person as p where p.uname=? and p.upwd=?";   
        Query q = this.getSession().createQuery(hql);   
        q.setString(0, per.getUname());   
        q.setString(1, per.getUpwd());   
        List all = q.list();   
           
        if(all.size() > 0){   
            flag = true;   
        }   
        else{   
            flag = false;   
        }   
           
        return flag;   
    }   

} 
package com.user.dao;

import java.util.List;

import org.hibernate.Query;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.user.vo.Person;

public class PersonManager extends HibernateDaoSupport{

public boolean isLogin(Person per){
   boolean flag = false;
  
   String hql = "From Person as p where p.uname=? and p.upwd=?";
   Query q = this.getSession().createQuery(hql);
   q.setString(0, per.getUname());
   q.setString(1, per.getUpwd());
   List all = q.list();
  
   if(all.size() > 0){
    flag = true;
   }
   else{
    flag = false;
   }
  
   return flag;
}

}

10. 创建Action

package com.user.action;   

import com.opensymphony.xwork2.ActionSupport;   
import com.user.dao.PersonManager;   
import com.user.vo.Person;   

public class LoginAction extends ActionSupport{   

    private String username;   
    private String password;   
    private PersonManager personManager;   

    public String getUsername() {   
        return username;   
    }   

    public void setUsername(String username) {   
        this.username = username;   
    }   

    public String getPassword() {   
        return password;   
    }   

    public void setPassword(String password) {   
        this.password = password;   
    }   

    public PersonManager getPersonManager() {   
        return personManager;   
    }   

    public void setPersonManager(PersonManager personManager) {   
        this.personManager = personManager;   
    }   

    @Override 
    public String execute() throws Exception {   
        String flag = "";   

        Person per = new Person();   
        per.setUname(this.username);   
        per.setUpwd(this.password);   
           
        if(personManager.isLogin(per)){   
            flag = "success";   
        }   
        else{   
            flag = "fail";   
        }   
           
        return flag;   
    }   
       
       

} 
package com.user.action;

import com.opensymphony.xwork2.ActionSupport;
import com.user.dao.PersonManager;
import com.user.vo.Person;

public class LoginAction extends ActionSupport{

private String username;
private String password;
private PersonManager personManager;

public String getUsername() {
   return username;
}

public void setUsername(String username) {
   this.username = username;
}

public String getPassword() {
   return password;
}

public void setPassword(String password) {
   this.password = password;
}

public PersonManager getPersonManager() {
   return personManager;
}

public void setPersonManager(PersonManager personManager) {
   this.personManager = personManager;
}

@Override
public String execute() throws Exception {
   String flag = "";

   Person per = new Person();
   per.setUname(this.username);
   per.setUpwd(this.password);
  
   if(personManager.isLogin(per)){
    flag = "success";
   }
   else{
    flag = "fail";
   }
  
   return flag;
}

}

11. 配置applicationContext.xml
