struts2文件上传下载及乱码问题解决
文件下载
private String inputPath;<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
public void setInputPath(String value) throws UnsupportedEncodingException {
inputPath = new String(value.getBytes("ISO-8859-1"),"UTF-8");
}
public InputStream getInputStream() throws Exception {
if(log.isDebugEnabled()){
log.debug("inputPath="+inputPath);
}
return new java.io.FileInputStream(inputPath);
// return ServletActionContext.getServletContext().getResourceAsStream(inputPath);
//使用上面的语句将无法获取到inputStream，如果资源恰好在web应用下面，则是可以的。
}
/**
* 下载日志文件
* @return
* @throws Excepiton
*/
public String download () throws Exception{
String fileName = inputPath.substring(inputPath.lastIndexOf(java.io.File.separator)+1, inputPath.length());
if(log.isDebugEnabled()){
log.debug("fileName="+fileName);
}
ServletActionContext.getResponse().setHeader("Content-Disposition", "attachment; filename="+new String(fileName.getBytes("gb2312"),"iso-8859-1"));
return SUCCESS;
}
注意：第一个转换，"ISO-8859-1"————"UTF-8" UTF-8是根据你自己的编码来处理
第二个转换，"gb2312"————"iso-8859-1" 你就不要改变了，不管你是什么编码，都这么处理就是了，只要你的客户用的是中文的操作系统，呵呵
配置文件的内容
<action name="download" class="com.work.qxgl.loglogin.LogLoginAction"
method="downloadLogs">
<result name="success" type="stream">
<param name="inputName">inputStream</param>
<param name="bufferSize">4096</param>
</result>
</action>
下载设置
<a href='<s:url action="download" namespace="/qxglloglogin"><s:param name="inputPath" value="filePath" /></s:url>'><s:property value="fileName" /></a>
文件上传
public File getUpload() {
return upload;
}
public void setUpload(File upload) {
this.upload = upload;
}
// since we are using <s:file name="upload" .../> the file name will be
// obtained through getter/setter of <file-tag-name>FileName
/**
* 如果表单域为fj，那么就叫getFjFileName;
* @return
*/
public String getUploadFileName() {
return fileName;
}
public void setUploadFileName(String fileName) {
this.fileName = fileName;
}
// since we are using <s:file name="upload" ... /> the content type will be
// obtained through getter/setter of <file-tag-name>ContentType
/**
* 如果表单域为fj，那么就叫getFjContentType
* @return
*/
public String getUploadContentType() {
return contentType;
}
public void setUploadContentType(String contentType) {
this.contentType = contentType;
}
在配置文件中限制上传文件的格式
< action name ="fileUpload" class ="tutorial.FileUploadAction" >
< interceptor-ref name ="fileUpload" >
< param name ="allowedTypes" >
image/bmp,image/png,image/gif,image/jpeg
</ param >
</ interceptor-ref >
< interceptor-ref name ="defaultStack" />
< result name ="input" > /FileUpload.jsp </ result >
< result name ="success" > /ShowUpload.jsp </ result >
</ action >
