一旦我将库 icefaces.jar icepush.jar icefaces_ace.jar 添加到我的类路径以使用 ACE 组件,我的 SaveAs 对话框就不会弹出?我不确定这是否是一个错误,但没有类路径中的库它可以工作。这是我的另存为方法:
public void downloadFile(String propertyPath) throws IOException {
ProxyFile fileToDownload = repBean.downloadFile(propertyPath);
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext externalContext = facesContext.getExternalContext();
HttpServletResponse response = (HttpServletResponse) externalContext.getResponse();
response.reset(); response.setContentType(fileToDownload.getContentType());
response.setHeader("Content-Length", String.valueOf(fileToDownload.getLength()));
response.setHeader("Content-disposition", "attachment; filename=\"" + fileToDownload.getName() + "\"");
BufferedInputStream input = null;
BufferedOutputStream output = null;
try {
input = new BufferedInputStream(fileToDownload.getContent());
output = new BufferedOutputStream(response.getOutputStream());
byte[] buffer = new byte[10240];
for (int length; (length = input.read(buffer)) > 0;) {
output.write(buffer, 0, length);
}
} finally {
output.close();
input.close();
facesContext.responseComplete();
}
}
