SSH 框架的搭建

SSH 框架的搭建

Structs1+spring+Hibernate

Structs  相当于mvc设计模式中V.C，即jsp页面和Servlet；

spring 管理业务逻辑，即Service；

Hibernate 管理DAO,持久层；

首先讲一下Hibernate和spring的整合：

　　1.加入相关的jar：mysql的 mysql-connector-java-5.1.13-bin.jar；

　　　　　　　　　　 Hibernate的就不一一列出的（上一篇文章有提到);特别注意的是要导slf4j相关的底层实现包 slf4j-nop-1.5.8.jar

　　　　　　　　　　 spring的相关jar（spring\reqlib底下所有，spring\spring-framework-3.1.0.RC1-with-docs\spring-framework-3.1.0.RC1\dist底下所有）;

　　2.提供spring的配置文件。applicationContext.xml;

复制代码
<?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:context="http://www.springframework.org/schema/context"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
         http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
         http://www.springframework.org/schema/context
         http://www.springframework.org/schema/context/spring-context-3.0.xsd
         http://www.springframework.org/schema/aop
         http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">

    <context:annotation-config />
    <aop:aspectj-autoproxy></aop:aspectj-autoproxy>
    <context:component-scan base-package="com"></context:component-scan>

</beans>
复制代码

　　3.配置数据库连接池。

复制代码
<?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:context="http://www.springframework.org/schema/context"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
         http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
         http://www.springframework.org/schema/context
         http://www.springframework.org/schema/context/spring-context-3.0.xsd
         http://www.springframework.org/schema/aop
         http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">

    <context:annotation-config />
    <aop:aspectj-autoproxy></aop:aspectj-autoproxy>
    <context:component-scan base-package="com"></context:component-scan>

    <bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource"
        destroy-method="close">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://127.0.0.1:3306/mysql" />
        <property name="username" value="root" />
        <property name="password" value="root" />
    </bean>
</beans>
复制代码

　　此时，写个测试类，测试下。（前提是数据库已存在表格t_user）；

复制代码
package Test;



import java.sql.Connection;
import java.sql.SQLException;


import org.apache.commons.dbcp.BasicDataSource;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;



public class T {

    public static void main(String[] args) {
        ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
        BasicDataSource dataSource = ac.getBean("myDataSource",BasicDataSource.class);
        Connection conn;
        try {
            conn = dataSource.getConnection();
            conn.createStatement().executeUpdate("insert into t_user values(null,'arron','1234')");
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        
    }

}
复制代码

　　4.配置sessionFactory;

复制代码
<?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:context="http://www.springframework.org/schema/context"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
         http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
         http://www.springframework.org/schema/context
         http://www.springframework.org/schema/context/spring-context-3.0.xsd
         http://www.springframework.org/schema/aop
         http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">

    <context:annotation-config />
    <aop:aspectj-autoproxy></aop:aspectj-autoproxy>
    <context:component-scan base-package="com"></context:component-scan>
<!--配置数据库连接池-->
    <bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource"
        destroy-method="close">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://127.0.0.1:3306/mysql" />
        <property name="username" value="root" />
        <property name="password" value="root" />
    </bean>
<!--配置sessionFactory-->    
    <bean id="mySessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="myDataSource"/>
    <property name="packagesToScan" value="com.kebin.pojo">
    </property>
    <property name="hibernateProperties">
      <props>
          <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.format_sql">true</prop>
                <prop key="hibernate.hbm2ddl.auto">update</prop>
                <prop key="hibernate.current_session_context_class">thread</prop>
      </props>
    </property>
  </bean>
    
</beans>
复制代码

　　配置完成了，写了User pojo类，和测试类，测试下。

User.java
复制代码
package com.kebin.pojo;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name="t_user")
public class User {
    private int id;
    private String name;
    private String password;
    
    @Id
    @GeneratedValue
    public int getId() {
        return id;
    }
    public void setId(int 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;
    }
}
复制代码
T.java
复制代码
package Test;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.kebin.pojo.User;

public class T {

    public static void main(String[] args) {
        ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
        SessionFactory sf = ac.getBean("mySessionFactory",SessionFactory.class);
        Session session = sf.getCurrentSession();
        Transaction ts = session.beginTransaction();
        ts.begin();
        User user = new User();
        user.setName("admin");
        user.setPassword("123456");
        session.save(user);
        ts.commit();

    }

}
复制代码

 　　接着往下写业务逻辑层。

UserDao.java
复制代码
package com.kebin.dao;

import com.kebin.pojo.User;

public interface UserDao {
    public void save(User user);
}
复制代码
UserDaoImpl.java
复制代码
package com.kebin.dao;

import org.springframework.stereotype.Component;

import com.kebin.pojo.User;
@Component("userDao")
public class UserDaoImpl implements UserDao {

    public void save(User user) {
        // TODO Auto-generated method stub

    }

}
复制代码
UserService.java
复制代码
package com.kebin.service;

import com.kebin.pojo.User;

public interface UserService {
    public void add(User user);
}
复制代码

　　书写一个DaoSupport类继承自HibernateTemplate；

复制代码
package com.kebin.dao;

import javax.annotation.Resource;

import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.stereotype.Component;

@Component
public class DaoSupport extends HibernateTemplate {
    private SessionFactory sessionFactory;
    @Resource(name="mySessionFactory")
    public void setSessionFactory(SessionFactory sessionFactory) {
        super.setSessionFactory(sessionFactory);
    }
    
}
复制代码
UserServiceImpl
复制代码
package com.kebin.service.impl;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.kebin.dao.DaoSupport;
import com.kebin.dao.UserDao;
import com.kebin.pojo.User;
import com.kebin.service.UserService;
@Service("userService")
public class UserServiceImpl extends DaoSupport implements UserService {
    private UserDao userDao;
    @Resource(name="userDao")
    public void setUserDao(UserDao userDao) {
        this.userDao = userDao;
    }

    public void add(User user) {
        this.save(user);

    }

}
复制代码

　　最后写个测试类T.java，进行测试下。这样hibernate和spring就配置好了。

复制代码
package Test;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.kebin.pojo.User;
import com.kebin.service.UserService;

public class T {

    public static void main(String[] args) {
        ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
        UserService userService = ac.getBean("userService",UserService.class);
        User user = new User();
        user.setName("kebin");
        user.setPassword("1111111");
        userService.add(user);

    }

}
复制代码

接下来，讲一下Spring 和 Struts 的整合

我这里用的是Struts1,可能很多公司都已经不用了的。

　　1.导入Struts的包，struts1\struts-1.3.10-all\struts-1.3.10\lib底下所有的包。

　　　（有两个包和hibernate重复了，删除就可以了。commons-logging.jar 和 antlr-2.7.6.jar 留下版本高的）；

　　2.拷入struts-config.xml配置文件；

　　　　（将struts-config.xml和applicationContext.xml都放在WEB-INF的底下）

　　3.书写UserAction.java和index.jsp页面。代码我直接贴出；

　　

 
 
UserAction.java
复制代码
package com.kebin.action;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.DynaActionForm;
import org.apache.struts.actions.DispatchAction;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;

import com.kebin.pojo.User;
import com.kebin.service.UserService;

@Controller
@Qualifier("/user")
public class UserAction extends DispatchAction {
    private UserService userService;

    @Resource(name = "userService")
    public void setUserService(UserService userService) {
        this.userService = userService;
    }

    public ActionForward execute(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception {

        DynaActionForm df = (DynaActionForm) form;
        // 配置了注解，直接将userService注入，这段读取的代码就不用了；
        // ApplicationContext ac = WebApplicationContextUtils.getRequiredWebApplicationContext(this.getServlet().getServletContext());
        // UserService userService = ac.getBean("userService",UserService.class);
        User user = new User();
        user.setName(df.getString("username"));
        user.setPassword(df.getString("password"));
        userService.add(user);
        return mapping.findForward("success");
    }

}
复制代码
index.jsp
复制代码
<%@ page language="java" contentType="text/html; charset=UTF-8"
    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>Insert title here</title>
</head>
<body>
    <form action="user.do?command=login" method="post">
        username:<input type="text" name="username"/><br>
        password:<input type="text" name="password"/><br>
        <input type="submit" value="tijiao">
    </form>
</body>
</html>
复制代码

　　4.配置web.xml;(注意中文乱码的配置)；

复制代码
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

    <servlet>
        <servlet-name>action</servlet-name>
        <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
        <init-param>
            <param-name>config</param-name>
            <param-value>/WEB-INF/struts-config.xml</param-value>
        </init-param>
        <load-on-startup>2</load-on-startup>
    </servlet>
    
    <!-- 配置spring的监听器，用以实现依赖注射 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!-- 配置spring的配置文件的读取路径 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/applicationContext.xml</param-value>
    </context-param>

    <!-- 借用spring 实现对中文乱码的修改 -->
    <filter>
        <filter-name>Set Character Encoding</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>Set Character Encoding</filter-name>
        <url-pattern>*.do</url-pattern>
    </filter-mapping>
    <!-- action 的配置     -->
    <servlet-mapping>
        <servlet-name>action</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
</web-app>
复制代码

　　5.配置applicationContext.xml;（这里只要加个bean标签，来代替action-mappings里面的action中type=""）;

复制代码
<?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:context="http://www.springframework.org/schema/context"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
         http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
         http://www.springframework.org/schema/context
         http://www.springframework.org/schema/context/spring-context-3.0.xsd
         http://www.springframework.org/schema/aop
         http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">

    <context:annotation-config />
    <aop:aspectj-autoproxy></aop:aspectj-autoproxy>
    <context:component-scan base-package="com"></context:component-scan>
    <!--配置数据库连接池 -->
    <bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource"
        destroy-method="close">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://127.0.0.1:3306/mysql" />
        <property name="username" value="root" />
        <property name="password" value="root" />
    </bean>
    <!--配置sessionFactory -->
    <bean id="mySessionFactory"
        class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <property name="dataSource" ref="myDataSource" />
        <property name="packagesToScan" value="com.kebin.pojo">
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.format_sql">true</prop>
                <prop key="hibernate.hbm2ddl.auto">update</prop>
                <prop key="hibernate.current_session_context_class">thread</prop>
            </props>
        </property>
    </bean>
    <!-- 用注解来代替struts-config.xml配置文件中action的type="com.kebin.action.UserAction" -->
    <bean name="/user" class="com.kebin.action.UserAction"></bean>
</beans>
复制代码

　　6.配置struts-config.xml；

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


<!DOCTYPE struts-config PUBLIC
          "-//Apache Software Foundation//DTD Struts Configuration 1.3//EN"
          "http://struts.apache.org/dtds/struts-config_1_3.dtd">

<struts-config>
    <form-beans>
        <form-bean name="login" type="org.apache.struts.action.DynaActionForm">
            <form-property name="username" type="java.lang.String"></form-property>
            <form-property name="password" type="java.lang.String"></form-property>
        </form-bean>
    </form-beans>

    <action-mappings>
        <action path="/user" name="login"
            parameter="command">
            <forward name="success" path="/ok.jsp"></forward>
        </action>
    </action-mappings>
    
<!-- 用注解来代替action-mappings配置中action标签对里的type="com.kebin.action.UserAction(此处)" -->    
    <controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor">
    </controller>
    <plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
        <set-property property="contextConfigLocation" value="/WEB-INF/applicationContext.xml" />
    </plug-in>
</struts-config>
复制代码

以上给出简单列子的配置，基本的配置已经完成。谢谢各位大牛给出宝贵的评价。
