一、同步上传文件
-
导入common-fileupload这个jar包。
- 配置 springmvc-servlet.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:context="http://www.springframework.org/schema/context"

<!-- 激活@Required @Autowired @Resource等标注-->

<!-- DispatcherServlet上下文，扫描base-package包中的类，并自动加载到spring容器中 -->
<context:component-scan base-package="com.shyroke.controller">

<!-- 启用@Component，@Controller，@Service，@Repository注解驱动 -->

<property name="maxUploadSize" value="10485760000"></property>
<property name="maxInMemorySize" value="40960"></property>
</bean>
<!-- 配置视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

<body>
<form method="post" id="file_form1" action="<%=request.getContextPath()%>/uploadController/uploadForm"
enctype="multipart/form-data">
<input type="text" name="dogid" id="dogid" value="用户名"/>
<input type="text" name="dogname" id="dogname" value="复选框1"/>
<input type="file" name="faceimage" id="faceimage" size="40"/>
<input type="submit" value="上传文件"/>
</form>
</body>
package com.shyroke.controller;
import java.io.File;
import java.io.InputStream;
import javax.servlet.ServletContext;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.multipart.MultipartFile;
import com.shyroke.bean.DogBean;
@Controller
@RequestMapping(value="/uploadController")
public class UploadController {
@Autowired
private ServletContext context;
@RequestMapping(value = "/uploadForm")
public String uploadFile(
DogBean dogBean,
@RequestParam(name = "faceimage", required = false) MultipartFile faceimage)
throws Exception {
System.out.println(dogBean);
System.out.println(faceimage);
String dogid = dogBean.getDogid();
String dogname = dogBean.getDogname();
String name = faceimage.getName();
String filename = faceimage.getOriginalFilename();
InputStream inputStream = faceimage.getInputStream();
/**
* 输出控件的名称,faceimage
*/
System.out.println("name = " + name);
/**
* 文件的名称
*/
System.out.println("filename = " + filename);
/**
* 获取文件流
*/
System.out.println("inputStream = " + inputStream);
String uploadDir = context.getRealPath("/uploadfiles");
System.out.println(uploadDir);
filename = System.currentTimeMillis() + "_" + filename;
File destFile = new File(uploadDir + "/" + filename);
faceimage.transferTo(destFile);
return null;
}
}
二、异步上传文件
-
导入common-fileupload这个jar包、配置 springmvc-servlet.xml 如上
- index.jsp
2：ajax来提交。
<form method="post" id="file_form2" action=""
enctype="multipart/form-data">
<input type="text" name="dogid" id="dogid" value="用户名"/>
<input type="text" name="dogname" id="dogname" value="复选框1"/>
<input type="file" name="faceimage" id="faceimage" size="40"/>
<input type="button" value="上传文件" onclick="uploadFile();"/>
</form>
package com.shyroke.controller;
import java.io.File;
import java.io.InputStream;
import java.util.HashMap;
import java.util.Map;
import javax.servlet.ServletContext;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.multipart.MultipartFile;
import com.shyroke.bean.DogBean;
@Controller
@RequestMapping(value = "/uploadController")
public class UploadController {
@Autowired
private ServletContext context;
@RequestMapping(value = "/uploadAjax")
@ResponseBody
public Map<String, Object> uploadAjax(DogBean dogBean,
@RequestParam(name = "faceimage", required = false) MultipartFile faceimage) throws Exception {
System.out.println(dogBean);
System.out.println(faceimage);
String dogid = dogBean.getDogid();
String dogname = dogBean.getDogname();
String name = faceimage.getName();
String filename = faceimage.getOriginalFilename();
InputStream inputStream = faceimage.getInputStream();
/**
* 输出控件的名称,faceimage
*/
System.out.println("name = " + name);
/**
* 文件的名称
*/
System.out.println("filename = " + filename);
/**
* 获取文件流
*/
System.out.println("inputStream = " + inputStream);
String uploadDir = context.getRealPath("/uploadfiles");
System.out.println(uploadDir);
Map<String, Object> jsonMap = new HashMap<String, Object>();
try {
filename = System.currentTimeMillis() + "_" + filename;
File destFile = new File(uploadDir + "/" + filename);
faceimage.transferTo(destFile);
jsonMap.put("flag", true);
} catch (Exception e) {
jsonMap.put("flag", false);
jsonMap.put("errorMsg", "错误");
}
return jsonMap;
}
}
