smartupload在传大文件时会内存溢出

根据异常信息来看是在创建文件的时候出错了，断点跟一下看看是不是路径什么的写错了，或者是文件重名了之类的

页面+处理的SERVLET代码需要jspSmartUpload组件

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.

出现这个错误的原因可能是自己访问地址的ip有问题输出你的ip地址看看是不是0.0.0.0.0.0.0.1这个是ipv6表示的本机地址对应的ipv4就是127.0.0.1. 这个地址在重命名文件的时候会出现错误所以我们可以将其改成其他的ip地址可以尝试换成自己局域网的ip地址或是自己的本机的ip地址即路径不再是http://localhost:8080/myupload/myuploa
