Spring文件上传配置

时间：2023-12-19 12:12:02

增加依赖jar包

        <dependency>

            <groupId>commons-fileupload</groupId>

            <artifactId>commons-fileupload</artifactId>

            <version>1.3.1</version>

        </dependency>

修改springmvc.xml配置文件，添加

    <!-- 启用文件上传支持 -->

    <bean id="multipartResolver"

        class="org.springframework.web.multipart.commons.CommonsMultipartResolver">

        <property name="maxUploadSize" value="100000" />

        <property name="maxInMemorySize" value="10240" />

    </bean>

controller代码

package com.test.controller;

import java.io.IOException;

import java.util.List;

import javax.annotation.Resource;

import org.apache.commons.logging.Log;

import org.apache.commons.logging.LogFactory;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.RequestParam;

import org.springframework.web.multipart.MultipartFile;

import org.springframework.web.servlet.ModelAndView;

import net.sf.json.JSONObject;

@Controller

public class ServiceDBController {

	private static Log log = LogFactory.getLog(ServiceDBController.class);

	@RequestMapping(value="test.do")

	public void test(@RequestParam("myFile")MultipartFile myFile) {

　　　　     //处理文件

	}

}

表单

<form action="${pageContext.request.contextPath}/test.do" method="post" id="frm-uploadfile" enctype="multipart/form-data">

    <input type="file" name="myFile" /> <!--注意这个name要和对应的spring的controller参数名称相同-->

    <input type="submit" value="上传文件">

</form>
