springMVC 获取本地项目路径 及后整理上传文件的方法

String path=request.getSession().getServletContext().getRealPath("upload/img/product");

//二进制上传
MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
//获取文件
CommonsMultipartFile fpic=(CommonsMultipartFile) multipartRequest.getFile("fpic");
//推断是否有文件提交
if(fpic!=null){
if(!fpic.isEmpty()){
String time=DataUtil.getCurrentTimeMillis();
String path=request.getSession().getServletContext().getRealPath("upload/img/product");
File file = new File(path+"/"+time+ ".jpg");
fpicurl = "upload/img/product/p"+time+".jpg";
try {
fpic.getFileItem().write(file);
} catch (Exception e) {
e.printStackTrace();
return;
}
}
}

须要工具包

import org.springframework.web.multipart.MultipartHttpServletRequest;

import org.springframework.web.multipart.commons.CommonsMultipartFile;

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

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

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import java.io.File;

import java.io.IOException;

import com.realgo.util.DataUtil;

class DataUtil

public static String getCurrentTimeMillis(){
return String.valueOf(System.currentTimeMillis());
}
