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
<pre><code>

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
   


    
}

</code></pre>

2. 上传图片
   <pre><code>
   /**
   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)
   }
   }
   )

   }
   </code></pre>

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
<pre><code>
@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"))
}
</code></pre>
3.保存文件 FileUtils 类
<pre><code>
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<String> 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<String,MultipartFile> files)
{ for (int i=0;i<files.size();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<String> getFilePaths(){
return filePaths;
}
public static void setFilePath(String path){
filePath=path;
}
}
</code></pre>
