#jfinal上传文件

该博客介绍了使用JFinal上传文件的具体步骤，包括创建web项目、导入jar包、配置web.xml、编写上传代码、配置静态页面等，最后部署项目到Tomcat进行文件上传，上传成功后可在本地Tomcat的webapps文件夹中查看文件。

1.创建web项目；

2.导入jar包

3.配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<display-name>jfinal-fileupload</display-name>
<filter>
   <filter-name>jfinal</filter-name>
   <filter-class>com.jfinal.core.JFinalFilter</filter-class>
   <init-param>
       <param-name>configClass</param-name>
       <param-value>com.jfinal.config.Myconfig</param-value>
   </init-param>
</filter>

<filter-mapping>
   <filter-name>jfinal</filter-name>
   <url-pattern>/*</url-pattern>
</filter-mapping>


<welcome-file-list>
<welcome-file>index.html</welcome-file>
</welcome-file-list>
</web-app>

4.创建包，并编写上传代码

Myconfig类：

package com.jfinal.config;

import com.jfinal.controller.FileUploadController;
import com.jfinal.render.ViewType;
import com.jfinal.template.Engine;

public class Myconfig extends JFinalConfig{

   @Override
   public void configConstant(Constants constant) {
       constant.setDevMode(true);
       constant.setViewType(ViewType.JSP);
       constant.setBaseUploadPath("my");

   }

   @Override
   public void configEngine(Engine arg0) {
       // TODO Auto-generated method stub

   }

   @Override
   public void configHandler(Handlers arg0) {
       // TODO Auto-generated method stub

   }

   @Override
   public void configInterceptor(Interceptors arg0) {
       // TODO Auto-generated method stub

   }

   @Override
   public void configPlugin(Plugins arg0) {
       // TODO Auto-generated method stub

   }

   @Override
   public void configRoute(Routes route) {
       route.add("/",FileUploadController.class);

   }

}

FileUploadController类：

package com.jfinal.controller;

import com.jfinal.core.Controller;
import com.jfinal.upload.UploadFile;

public class FileUploadController extends Controller {

   public void upload() {

       UploadFile file = getFile("file");

   }

}

5.配置静态页面：upload.html

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<form action="upload" enctype="multipart/form-data" method="post">

文件:<input type="file" name="file"/>
<input type="submit" value="tijiao"/>

</form>

</body>
</html>

6.部署项目到Tomcat，请求http://localhost:8080/jfinal-fileupload/upload.html，上传文件。

上传成功后可以到本地Tomcat下的webapps文件夹中上传文件项目下查看上传的文件。
