jspsmartupload 中文乱码 上传文件
解决jspsmartupload上传文件中文乱码 采用jspsmartupload上传文件时,如果文件名含有中文,在服务器端取得文件名是会出现乱码。如果表单项中填写了中文,一样会有乱码问题。看了下jspsmartupload的源码,改了两个地方,现在可以没有乱码问题了。 第一个地方,修改类SmartUpload中的upload()方法 // //这次用jspSmartUpload做文件上传下载, //该组件默认是GBK编码,当上传的文件名为中文时, //我将文件名getBytes()下,将GBK改成UTF-8。测试了下,貌似没问题, //突然有一次上传一文件时,发现最后几个字乱码,一直是??。在拿些文件测试, // 后来知道了是当文件名为中文奇数时,会乱码,而且还上传不了。 // 再做测试,找原因,查看字符的长度,转成16进制看结果。觉得是jspSmartUpload组件对中文支持不足的问题。 http://ru-yi86.javaeye.com/blog/368553 Java代码 1. public void upload() 2. throws SmartUploadException, IOException, ServletException 3. { 4. int totalRead = 0; 5. int readBytes = 0; 6. long totalFileSize = 0L; 7. boolean found = false; 8.
