使用spring mvc+localResizeIMG实现HTML5端图片压缩上传的功能

*/
@ResponseBody
@RequestMapping("common/fileUploadPicture")
public Object fileUploadPicture(String imgdata, HttpServletRequest request) {
LOGGER.info("[文件上传（fileUploadPicture）][params:imgdata=" + imgdata + "]");
BASE64Decoder decoder = new BASE64Decoder();
try {
String basePath = request.getRealPath("/upload_files");
string imgPath=basePath+"/test.jpg";
// new一个文件对象用来保存图片，默认保存当前工程根目录
File imageFile = new File(imgPath);
// 创建输出流
FileOutputStream outputStream = new FileOutputStream(imageFile);
// 获得一个图片文件流，我这里是从flex中传过来的
byte[] result = decoder.decodeBuffer(imgdata.split(",")[1]);//解码
for (int i = 0; i < result.length; ++i) {
if (result[i] < 0) {// 调整异常数据
result[i] += 256;
}
}
outputStream.write(result);

return new Result(true, imgPath);
} catch (AppException e1) {
LOGGER.error("[文件上传（fileUpload）-fastdfs][errors:" + e1 + "]");
return new Result(false, "文件上传失败");
} catch (Exception e) {
LOGGER.error("[文件上传（fileUpload）][errors:" + e + "]");
return new Result(false, "文件上传失败");
}finally{
outputStream.flush();
outputStream.close();

}
}

Result类：

import java.io.Serializable; 
public class Result implements Serializable{
private static final long serialVersionUID = 1L;
private boolean success;
private String message; 
 public Result() {
success = true;
} 
 public Result(boolean success, String message) {
this.success = success;
this.message = message;
} 
 public boolean isSuccess() {
return success;
} 
 public void setSuccess(boolean success) {
this.success = success;
} 
 public String getMessage() {
return message;
} 
 public void setMessage(String message) {
this.message = message;
} 
 @Override
public String toString() {
return "Result [success=" + success + ", message=" + message + "]";
} 
}
