What a may to reload a jsf page after primefaces upload?
在primefaces上传后重新加载jsf页面有什么可能？
I try with javascript oncomplete="javascript:window.location.reload()", but it's doesn't work:
我尝试使用 javascript oncomplete="javascript:window.location.reload()"，但它不起作用：
xhtml:
html:
<h:form>
<p:messages showDetail="true"/>
<p:fileUpload fileUploadListener="#{revistauploadBean.upload}"
mode="advanced" dragDropSupport="false" merge="true"
uploadLabel="Enviar" cancelLabel="Cancelar"
oncomplete="javascript:window.location.reload()"
label="Procurar PDF" sizeLimit="1000000000" fileLimit="3"
allowTypes="/(\.|\/)(pdf)$/" />
</h:form>
Bean:
豆角，扁豆：
public void upload(FileUploadEvent event) throws SQLException {
LoginAuthentication user = new LoginAuthentication();
FacesMessage msg = new FacesMessage("Success! ", event.getFile().getFileName()
+ " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, msg);
// Do what you want with the file
try {
copyFile(event.getFile().getFileName(), event.getFile().getInputstream());
ConectaBanco mysql = new ConectaBanco();
mysql.insere("INSERT INTO edicoes VALUES (NULL, '"
+ mysql.pegaIDrev(user.getNome())
+ "', NULL, NULL, NULL, NULL, '"
+ event.getFile().getFileName()
+ "' );");
File pasta = new File(caminhoPastaPDF
+ "/convertidos/"
+ event.getFile().getFileName());
pasta.mkdir();
convertePdf(event.getFile().getFileName());
FacesMessage msg1 = new FacesMessage("Succesful", event.getFile().getFileName()
+ " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, msg1);
} catch (IOException e) {
e.printStackTrace();
}
}
public void copyFile(String fileName, InputStream in) {
try {
// write the inputStream to a FileOutputStream
OutputStream out = new FileOutputStream(new File(destination + fileName));
int read = 0;
byte[] bytes = new byte[1024];
while ((read = in.read(bytes)) != -1) {
out.write(bytes, 0, read);
}
in.close();
out.flush();
out.close();
////System.out.println("New file created!");
}
}
There are another ways to do that?
I want to refresh a <a4j:repeat>
还有其他方法可以做到这一点吗？我想刷新一个<a4j:repeat>

<p:fileUpload />has an updateattribute which, given @formvalue, renders the whole formagain.
<p:fileUpload />有一个update属性，给定@form值，再次呈现整个表单。
<p:fileUpload fileUploadListener="#{fileUploadController.handleFileUpload}"
mode="advanced" dragDropSupport="false"
update="@form" sizeLimit="100000" fileLimit="3"
allowTypes="/(\.|\/)(gif|jpe?g|png)$/" />
Otherwise, if you want to get rid of ajax features, you also have the basic fileUploadcomponent.
否则，如果您想摆脱 ajax 功能，您还有基本的 fileUpload组件。
<p:fileUpload value="#{fileUploadController.file}" mode="simple"/>
<p:commandButton value="Submit" ajax="false"
actionListener="#{fileUploadController.upload}"/>
Basically, try not javascripting what is already done!
基本上，尽量不要对已经完成的事情使用javascript！

Please, try to use
请尝试使用
onsuccess="location.reload();"
It works for me pretty well. I am using it to reload my page after hitting on save button to see new uploaded file. It would not work when you use updating all forms
update="@(form)"
它对我很有效。在点击保存按钮以查看新上传的文件后，我正在使用它来重新加载我的页面。当您使用更新所有表单时它不起作用
update="@(form)"
