jsf2.0 文件上传组件

上传者： hblty | 上传时间： 2022-05-14 03:09:13 | 文件大小： 376KB | 文件类型： RAR
由于JSF2.0标准实现没有提供文件上传组件，而实际应用中很多时候需要上传文件，为了方便开发，我做了一个基于JSF2.0的文件上传组件，上传使用的是Apache 的commons-fileupload组件，我已经将commons-fileupload-1.2.1.jar和commons-io-1.3.2.jar打包成一个lfaces.jar文件，使用时无需导入这两个jar文件，我使用的是Facelets技术，使用时很简单，导入命名空间后就可以使用标签（）了，这个标签和标签使用方法一样，具体请参考例子。补充说明：是以临时文件存放在服务器上的，上传后需要自行处理，响应之前（JSF处理完毕）将会删除该临时文件，要设置上传的参数，比如文件存放目录，上传大小等，请在源目录（src）下建一个名为uploadfile.properties的文件，内容如下： #设置用于存放用户上传的文件夹，可以是绝对路径，例：C:/upload，也可是相对路径，例：/upload， #文件上传后是以.tmp为后缀的临时文件存储在服务器上，请求处理完成后系统将自动删除该临时文件，需要自行保存文件到需求的目录 uploadFile.path=E:/ #设置上传文件总大小的上限 uploadFile.sizeMax=1024*1024*50 #设置上传文件大小的上限 uploadFile.fileSizeMax=1024*1024*10 #设置缓存大小，如果文件大于缓存大小时，则先把文件放到缓存中 uploadFile.sizeThreshold=1024*1024 #设置上传文件类型 uploadFile.extFilter=.jpg|.jpeg|.gif|.bmp|.png|.xls|.doc|.txt
