ssh环境搭建并实现登录功能

参照了这篇博客，但是里面有些地方进行了更改

在昨天添加struts2和hibernate的中间添加spring，比较简单，方法类似，直接finish就可以。hibernate需要next进行相应的选择。
然后自动生成了applicationContext.xml。
注意三个框架的顺序是struts2，spring，hibernate。然后我们可以看到数据库的配置信息加入到了applicationContext.xml。
后面反向生成实体类和dao的时候配置信息也加入到了applicationContext.xml。
但是我们自己编写的dao，impl，service需要自己进行配置
ssh环境搭建并实现登录功能

User.java和User.hbm.xml反向生成

package com.us.mine.beans;

/**

 * User entity. @author MyEclipse Persistence Tools

 */

public class User implements java.io.Serializable {

    // Fields

    private Integer userId;

    private String userName;

    private String password;

    private Integer gender;

    // Constructors

    /** default constructor */

    public User() {

    }

    /** full constructor */

    public User(String userName, String password, Integer gender) {

        this.userName = userName;

        this.password = password;

        this.gender = gender;

    }

    // Property accessors

    public Integer getUserId() {

        return this.userId;

    }

    public void setUserId(Integer userId) {

        this.userId = userId;

    }

    public String getUserName() {

        return this.userName;

    }

    public void setUserName(String userName) {

        this.userName = userName;

    }

    public String getPassword() {

        return this.password;

    }

    public void setPassword(String password) {

        this.password = password;

    }

    public Integer getGender() {

        return this.gender;

    }

    public void setGender(Integer gender) {

        this.gender = gender;

    }

}

User.java

<?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">

<!--

    Mapping file autogenerated by MyEclipse Persistence Tools

-->

<hibernate-mapping>

    <class name="com.us.mine.beans.User" table="user" catalog="world">

        <id name="userId" type="java.lang.Integer">

            <column name="userId" />

            <generator class="native" />

        </id>

        <property name="userName" type="java.lang.String">

            <column name="userName" length="16" not-null="true" />

        </property>

        <property name="password" type="java.lang.String">

            <column name="password" length="16" not-null="true" />

        </property>

        <property name="gender" type="java.lang.Integer">

            <column name="gender" not-null="true" />

        </property>

    </class>

</hibernate-mapping>

User.hbm.xml

然后是登录页,注意元素的name要和action类中的一致，form的action要和struts.xml中一致。加一个登录成功页main.jsp。

<body>

    <form method="post" action="Login">

           用户名：<input name="username" type="text" />                        

                密码：<input name="password" type="password" />        <input

            name="Submits" type="submit" value="登录" />       <input name="ReSet"

            type="reset" value="重置" /> 

    </form>

</body>

index.jsp

然后LoginDao,LoginDaoImpl,LoginService,LoginServiceImpl

package com.us.mine.dao;

public interface LoginDao {

    boolean login(String username, String password);

}

LoginDao.java

package com.us.mine.dao;

import java.util.List;

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

import com.us.mine.beans.User;

public class LoginDaoImpl extends HibernateDaoSupport implements LoginDao {

    @Override

    public boolean login(String username, String password) {

        List<User> u=this.getHibernateTemplate().find("from User where userName=? and password=?",username,password);

        Boolean flag=false;

        if(u.size()>0){

            flag=true;

        }

        return flag;

    }

}

LoginDaoImpl

package com.us.mine.service;

public interface LoginService {

    boolean login(String username, String password);

}

LoginService

package com.us.mine.service;

import com.us.mine.dao.LoginDao;

import com.us.mine.dao.LoginDaoImpl;

public class LoginServiceImpl implements LoginService {

    private LoginDao logindao;

    public void setLogindao(LoginDaoImpl loginDao) {

        this.logindao = loginDao;

    }

    @Override

    public boolean login(String username, String password) {

        return logindao.login(username, password);

    }

}

LoginServiceImpl

然后是LoginAction 并在struts.xml中进行配置,注意action的class填写的和application里面注入的action的id相同

package com.us.mine.action;

import com.opensymphony.xwork2.ActionSupport;

import com.us.mine.service.LoginService;

public class LoginAction extends ActionSupport{

    private LoginService loginservice;

    private String password;

    private String username;

    public LoginService getLoginservice() {

        return loginservice;

    }

    public void setLoginservice(LoginService loginservice) {

        this.loginservice = loginservice;

    }

    public String getPassword() {

        return password;

    }

    public void setPassword(String password) {

        this.password = password;

    }

    public String getUsername() {

        return username;

    }

    public void setUsername(String username) {

        this.username = username;

    }

    public String login(){

        Boolean flag=loginservice.login(username, password);

        if(flag){

            return SUCCESS;

        }else{

            return INPUT;

        }

    }

}

LoginAction

<?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" namespace="/">

        <action name="Login" class="logina" method="login">

            <result name="input">/index.jsp</result>

            <result name="success">/main.jsp</result>

        </action>

    </package>

</struts>

struts.xml

最后是applicationContext.xml。主要是最下面3个bean,可以看到类之间的注入关系

<?xml version="1.0" encoding="UTF-8"?>

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

        <property name="username" value="root"></property>

        <property name="password" value="1234"></property>

    </bean>

    <bean id="sessionFactory"

        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

        <property name="dataSource">

            <ref bean="dataSource" />

        </property>

        <property name="hibernateProperties">

                <prop key="hibernate.dialect">

        </property>

        <property name="mappingResources">

                <value>com/us/mine/beans/User.hbm.xml</value>

            </list>

        </property>

    </bean>

    <bean id="UserDAO" class="com.us.mine.dao.UserDAO">

        <property name="sessionFactory">

            <ref bean="sessionFactory" />

        </property>

    </bean>

    <!-- Dao注入sessionFactory -->

    <bean id="logind" class="com.us.mine.dao.LoginDaoImpl">

        <!-- 注入持久化操作所需的SessionFactory -->

        <property name="sessionFactory">

            <ref bean="sessionFactory" />

        </property>

    </bean>

    <!-- service注入dao id为下面的ref class为service实现类 -->

    <bean id="logins" class="com.us.mine.service.LoginServiceImpl">

        <property name="logindao" ref="logind"></property>

    </bean>

    <!-- Action注入service id="" 注入 class="action路径" name="loginservice"与LoginAction中声明的要保持一致

        ref随便取 -->

    <bean id="logina" class="com.us.mine.action.LoginAction" scope="prototype">

        <property name="loginservice" ref="logins"></property>

    </bean>

</beans>

applicationContext.xml

运行后一直报错，发现上面的配置文件少了

<property name="driverClassName" value="com.mysql.jdbc.Driver"></property>加上后可以运行
