Struts+Spring+Hibernate环境下文件上传下载示例(上传)

开发环境：MyEclipse6.0

1、第一步创建一个web工程，配置好SSH环境。

       

2、建立实体类 Tfile.java

 

 

package model;

public class Tfile ...{
    private String fileId;

    private String fileName;

    private byte[] fileContent;

    private String remark;

    public String getFileId() ...{
        return fileId;
    }

    public void setFileId(String fileId) ...{
        this.fileId = fileId;
    }

    public String getFileName() ...{
        return fileName;
    }

    public void setFileName(String fileName) ...{
        this.fileName = fileName;
    }

    public byte[] getFileContent() ...{
        return fileContent;
    }

    public void setFileContent(byte[] fileContent) ...{
        this.fileContent = fileContent;
    }

    public String getRemark() ...{
        return remark;
    }

    public void setRemark(String remark) ...{
        this.remark = remark;
    }

}
 
 

3、完成OR映射文件:Tfile.hbm.xml

 

 

<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
  <class table="t_file" name="model.Tfile">
    <id name="fileId" column="FILE_ID">
      <generator class="uuid"/>
    </id>
    <property name="fileName" column="FILE_NAME"/>
    <property name="remark" column="FILE_REMARK"/>   
    <property name="fileContent"
    type="org.springframework.orm.hibernate3.support.BlobByteArrayType"
    column="FILE_CONTENT" lazy="true"
    >   
    </property>
  </class>
</hibernate-mapping>
 
 

4、完成Hibernate配置文件：hibernate.cfg.xml

 

 

<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
  <session-factory>
    <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
    <property name="hibernate.connection.url">jdbc:mysql://127.0.0.1/fileupload</property>
    <property name="hibernate.connection.username">root</property>
    <property name="hibernate.connection.password">root</property>
    <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
    <property name="hibernate.show_sql">true</property>
    <property name="hibernate.hbm2ddl.auto">create</property>
    <mapping resource="model/Tfile.hbm.xml"/>
   
  </session-factory>
</hibernate-configuration>
 

5、建立 FileManager.java

 

 

package manager;

import model.Tfile;

public interface FileManger ...{
    /** *//**
     * 保存上传的文件
     * @param tfile
     */
    public void save(Tfile tfile);
}
 
 

6、实现保存文件功能:FileManagerImpl.java

 

 

package manager;

import model.Tfile;

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

public class FileManagerImpl extends HibernateDaoSupport implements FileManger ...{

    @Override
    public void save(Tfile tfile) ...{
        getHibernateTemplate().save(tfile);
    }

}
 
7、编写相对应的Action和ActionFrom

FileAcion.java

 

 

package web;

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

import manager.FileManger;
import model.Tfile;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

public class FileAction extends Action ...{

    private FileManger fileManager;
    public ActionForward execute(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception ...{
       
        FileActionForm faf=(FileActionForm)form;
       
        Tfile tfile =new Tfile();
       
        tfile.setRemark(faf.getRamark());
        tfile.setFileContent(faf.getMyfile().getFileData());
        tfile.setFileName(faf.getMyfile().getFileName());
       
        fileManager.save(tfile);
       
        return mapping.findForward("success");
    }
    public void setFileManager(FileManger fileManager) ...{
        this.fileManager = fileManager;
    }
   
}
 
 

FileActionForm.java

 

 

 

package web;

import org.apache.struts.action.ActionForm;
import org.apache.struts.upload.FormFile;

public class FileActionForm extends ActionForm ...{
    private FormFile myfile;
   
    private String ramark;

    public FormFile getMyfile() ...{
        return myfile;
    }

    public void setMyfile(FormFile myfile) ...{
        this.myfile = myfile;
    }

    public String getRamark() ...{
        return ramark;
    }

    public void setRamark(String ramark) ...{
        this.ramark = ramark;
    }

}
 
8、配置Spring文件:

applicationContext-actions.xml：主要是配置Action

applicationContext-beans.xml：Bean配置

applicationContext-common.xml：这个文件主要是配置SessionFactory和事务管理

1、applicationContext-actions.xml

 

 

<?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:aop="http://www.springframework.org/schema/aop"
         xmlns:tx="http://www.springframework.org/schema/tx"
         xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
           http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd
           http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">   
   
    <bean name="/upload" class="web.FileAction" scope="prototype">
        <property name="fileManager" ref="fileManager"></property>
    </bean>  
</beans>
 
 

2、applicationContext-beans.xml

 

 

<?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:aop="http://www.springframework.org/schema/aop"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
           http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd
           http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">

    <bean id="fileManager" class="manager.FileManagerImpl">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>
</beans>
 

3、applicationContext-common.xml

 

 

<?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:aop="http://www.springframework.org/schema/aop"
         xmlns:tx="http://www.springframework.org/schema/tx"
         xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
           http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd
           http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">
   
    <!-- lobHandler -->
    <bean id="lobHandler" class="org.springframework.jdbc.support.lob.DefaultLobHandler"/>
    <!-- lobHandel 关于这个bean，请大家Google查看起说明，这里就不解释了，因为本身我也不是太了解 -->

    <!-- 配置sessionFactory -->
    <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="configLocation">
            <value>classpath:hibernate.cfg.xml</value>
        </property>   
        <property name="lobHandler">
          <ref bean="lobHandler"/>       
        </property>           
    </bean>   

    <!-- 配置事务管理器 -->   
    <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory">
            <ref local="sessionFactory"/>
        </property>       
    </bean>
   
    <!-- 配置事务传播特性 -->      
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="save*" propagation="REQUIRED"/>
            <tx:method name="*" read-only="true"/>
        </tx:attributes>
    </tx:advice>
   
    <!-- 配置哪些类的方法进行事务管理 -->
    <aop:config>
        <aop:pointcut id="allManagerMethod" expression="execution (* manager.*.*(..))"/>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="allManagerMethod"/>
    </aop:config>
              
</beans>
 
 

9、struts-config.xml文件的配置：

 

 

<?xml version="1.0" encoding="ISO-8859-1" ?>

<!DOCTYPE struts-config PUBLIC
          "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN"
          "http://jakarta.apache.org/struts/dtds/struts-config_1_2.dtd">
<struts-config>   
   <form-beans>
   <form-bean name="fileForm" type="web.FileActionForm"></form-bean> 
   </form-beans>

   <action-mappings>
   <!--  upload  begin -->
   <action path="/upload"
               type="org.springframework.web.struts.DelegatingActionProxy"
               name="fileForm"
               scope="request"                             
   >
    <forward name="success" path="/index.jsp"></forward>
   </action>
   </action-mappings>
    <message-resources parameter="MessageResources" />
 
</struts-config>

 
 

10、最后一步是上传文件页面

 

<form action="upload.do" method="post" enctype="multipart/form-data">
     文件说明：<input type="text" name="remark"/><br>
    文件：<input type="file" name="myfile"  /><br>
    <input type="submit" value="保存"/>
</form>
 

上传成功之后，我直接返回了index.jsp,即文件上传页面.想看到底有没有上传成功,去数据库查看即可.
