1、通過commons-fileupload和commons.io來實現。
導入相關JAR包: commons.fileupload-1.2.0.jar和commons.io-1.4.0.jar
2、配置springmvc的配置解析器
<bean id="multipartResolver" class= "org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="defaultEncoding" value="UTF-8"></property> <property name="maxUploadSize" value="1048576000"></property> <property name="maxInMemorySize" value="40960"></property> </bean>
3、配置jsp頁面
<body> <form action="upload.do" method="post" enctype="multipart/form-data"> file:<input type="file" name="file"/> <input type="submit" value="上傳"/> </form> </body>
4、Controller代碼
@RequestMapping("/upload")
public String fileupload(@RequestParam("file") CommonsMultipartFile file, HttpServletRequest req) throws IOException{
//獲取文件名
//file.getOriginalFilename();
//獲取上傳文件的路徑
String path = req.getRealPath("/fileupload");
InputStream is = file.getInputStream();
OutputStream os = new FileOutputStream(new File(path,file.getOriginalFilename()));
int len = 0;
byte[] buffer = new byte[400];
while((len=is.read(buffer))!=-1){
os.write(buffer, 0, len);
}
os.close();
is.close();
return "/index.jsp";
}批量上傳的代碼
@RequestMapping("/batch")
public String fileupload(@RequestParam("file") CommonsMultipartFile file[], HttpServletRequest req) throws IOException{
//獲取文件名
//file.getOriginalFilename();
//獲取上傳文件的路徑
String path = req.getRealPath("/fileupload");
for(int i =0;i<file.length;i++){
InputStream is = file[i].getInputStream();
OutputStream os = new FileOutputStream(new File(path,file[i].getOriginalFilename()));
int len = 0;
byte[] buffer = new byte[400];
while((len=is.read(buffer))!=-1)
os.write(buffer, 0, len);
os.close();
is.close();
}
return "/index.jsp";
}
