swift 利用Alamofire 上传图片到java服务器

做app 开发避免不了上传文件，图片等存到服务器上,客户端只是实现单纯的上传图片，还有传入其他的参数(待更新)。
首先来看客户端的代码
1.获取本地图片

 
 
func saveImage(currentImage:UIImage,imageName:NSString){
 
 
    var imageData:NSData = UIImageJPEGRepresentation(currentImage, 0.5)
    var fullPath:String = NSHomeDirectory().stringByAppendingPathComponent("Documents").stringByAppendingPathComponent(imageName as String)
    
    imageData.writeToFile(fullPath as String, atomically: false)
    var fileURL = NSURL(fileURLWithPath: fullPath)
 //开始上传操作
   


    
}
 
 

2. 上传图片
   

   
    /**
    上传照片
    
   :param: url 上传url
    :param: path 图片path
    **/
    static func uploadImage(url:String,parameter:String,imagePath:NSURL ,requestDelegate:RequestDelegate){
    Alamofire.upload(
    .POST,
    URLString: url,
    multipartFormData: { multipartFormData in
    multipartFormData.appendBodyPart(fileURL: imagePath, name: "file")
    },
    encodingCompletion: { encodingResult in
    switch encodingResult {
    case .Success(let upload, _, _):
    upload.responseJSON { request, response, JSON, error in
    println(request)
    println(response)
    println(error)
    println(JSON)
    }
    case .Failure(let encodingError):
    println(encodingError)
    }
    }
    )
    
   }
    

接下来我们看Java服务器端代码
1.配置文件
maven 的pom.xml 配置

spring 配置

2.在controller 获取文件

 
 
 @RequestMapping(value = "/ updateProfile.do") 
 
 @ResponseBodypublic JSONObject updateProfile(HttpServletRequest request) throws IOException{ 
 
 if(request instanceof MultipartHttpServletRequest){ 
 
 MultipartHttpServletRequest multipartHttpServletRequest=(MultipartHttpServletRequest) request; 
 
 FileUtils.saveFile(request, multipartHttpServletRequest.getFile("file")) 
 
 } 
 
 

3.保存文件 FileUtils 类

 
 
 package com.ambimmort.app.framework.uitls; 
 
 import org.springframework.web.multipart.MultipartFile; 
 
 import org.w3c.dom.stylesheets.LinkStyle; 
 
 import javax.servlet.http.HttpServletRequest; 
 
 import java.io.File; 
 
 import java.util.ArrayList; 
 
 import java.util.List; 
 
 import java.util.Map; 
 
 import java.util.UUID; 
 
 /**文件操作utils * * Created by Darker on 15/5/11. */ 
 
 public class FileUtils { 
 
 private static String filePath; 
 
 private static ArrayList filePaths=new ArrayList<>(); 
 
 public static boolean saveFile(HttpServletRequest request,MultipartFile file) 
 
 { // 判断文件是否为空 
 
 if (!file.isEmpty()) { 
 
 try { 
 
 String localFilePath=null; 
 
 filePath= "/uploads/" +UUID.randomUUID()+"_"+System.currentTimeMillis()+".png"; // 文件保存路径 
 
 localFilePath =request.getSession().getServletContext().getRealPath("/")+filePath; 
 
 System.out.println("filepath="+filePath); 
 
 // 转存文件 
 
 file.transferTo(new File(localFilePath)); 
 
 setFilePath(filePath); 
 
 return true; 
 
 } catch (Exception e) { 
 
 e.printStackTrace(); 
 
 } 
 
 } 
 
 return false; 
 
 } 
 
 public static boolean saveFiles(HttpServletRequest request,Map files) 
 
 { for (int i=0;i //有一张图片没上传成功，则return false 
 
 MultipartFile multipartFile=files.get("file"+i); 
 
 if (saveFile(request,multipartFile)){ 
 
 filePaths.add(getFilePath()); 
 
 }else{ 
 
 return false; 
 
 } 
 
 } 
 
 return true; 
 
 } 
 
 public static String getFilePath(){ 
 
 return filePath ; 
 
 } 
 
 public static ArrayList getFilePaths(){ 
 
 return filePaths; 
 
 } 
 
 public static void setFilePath(String path){ 
 
 filePath=path; 
 
 } 
 
 }
