个人冲刺阶段3
一、今日内容
我今天进行团队冲刺的第一阶段,我们一起讨论并总结了昨天遇到的验证码问题,然后继续今天的编码任务。
二、预期本阶段工作量
预期本阶段工作用四天时间完成,本阶段主要任务为十天冲刺,第三天的任务已经完成。
还剩余的工作时间:七天
三、每日会议照片
四、每日任务看板照片

遇到的问题总结:
-裁剪图片发生偏移现象
解决办法:使用压缩后的图片等比例收集裁切坐标信息
-MultipartFile 和 File之间相互转化
第一种方法:
MultipartFile file = xxx;
CommonsMultipartFile cf= (CommonsMultipartFile)file;
DiskFileItem fi = (DiskFileItem)cf.getFileItem();
File f = fi.getStoreLocation();
会在项目的根目录的临时文件夹下生成一个文件;
第二种方法:
transferTo(File dest);
会在项目中生成一个新文件;
第三种方法:
File f = (File) xxx 强转即可。前提是要配置multipartResolver,要不然会报类型转换失败的异常。
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="maxUploadSize" value="104857600"/>
<property name="maxInMemorySize" value="4096"/>
</bean>
第四种方法:
Workbook wb = Workbook.getWorkbook(xxx .getInputStream());
转换为输入流,直接读取;
第五种方法:
byte[] buffer = myfile.getBytes();
先转换为字节数组,没试过;
第六种方法:
直接转成输入流
MultipartFile file=xxx;
is = file.getInputStream();
src = javax.imageio.ImageIO.read(is);
ret = src.getWidth(null); // 得到源图宽
