带进度条的文件上传(java+ajax源码) 在写代码的时候,还要用到关于servlet的包servlet-api.jar。 写完后调试的过程中,老报错:java.lang.NoClassDefFoundError: org/apache/commons/io/output/DeferredFileOutputStream,后来一查才知道少了commons-io-1.2.jar,加上后,就ok了。 关于获取及显示进度部分,用了我原来自己写的一个ajax的应用架构,从中抽取了部分代码出来,注意,js文件只适用于UTF-8编码的页面,因为现在我只写UTF-8编码的页面了,国际化方便。 progressUpload.jar中,包含了commons-fileupload-1.1.1.jar,servlet-api.jar,commons-io-1.2.jar,在progressUpload.jar中,还包含一个属性文件,里面是一些默认配置,可根据自己的需要修改。 由于有源码,怎么用可以自己看源码,此外,那个例子中也写了,在此不再赘述。例子中只取到了FileItem,再将item保存一下就ok了,示例代码: File upFile = new File(remoteFilePath) try \{ item.write(upFile) fileInfo.put("infotip", "上传成功.") } catch (java.lang.Exception e) \{ fileInfo.put("infotip", "上传失败.") }-with the progress of the file upload (java ajax OSS) in writing code, also used on packages servlet servlet-api.jar. After the finish debugging process, the old errors : java.lang.NoClassDefFoundError : org / apache / commons / io / output / DeferredFil eOutputStream. Later, an investigation will know less commons-io - 1.2.jar, plus, on the ok. On access and display some progress with my own original written by a ajax application architectures, from taking part code, and the attention js document only applies to UTF-8 encoded pages. now I just write UTF-8 encoded pages, international convenience. ProgressUpload.jar, contains commons - fileupload - 1.1.1.jar. servlet-api.jar, commons-io - 1.2.jar. In progressUpload.jar, also includes an attribute documents, There is some of the default conf 下载
