Is there any way to get the URL of the page which is loaded?
I would like the URL of the page which is loaded, in my controller i will call a method getUrlOfPage() in init() method .
I need the URL source to use it as a input for exporting the context in it.
How to get the URL of the page?
It's available by HttpServletRequest#getRequestURL() (with domain) or getRequestURI() (without domain). The HttpServletRequest itself is in turn available through JSF API via ExternalContext#getRequest().
Thus, so:
public void someMethod() {
HttpServletRequest request = (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
String url = request.getRequestURL().toString();
String uri = request.getRequestURI();
// ...
}
Or, if you're using CDI @Named to manage beans, and you're on JSF 2.3 or newer, then this is also possible through javax.faces.annotation.ManagedProperty:
@Inject @ManagedProperty("#{request.requestURL}")
private StringBuffer url; // +setter
@Inject @ManagedProperty("#{request.requestURI}")
private String uri; // +setter
public void someMethod() {
// ...
}
Or, if you're using CDI @Named to manage beans, then this is also possible, also on older JSF versions:
@Inject
private HttpServletRequest request;
public void someMethod() {
String url = request.getRequestURL().toString();
String uri = request.getRequestURI();
// ...
}
Or, if you're still using the since JSF 2.3 deprecated @ManagedBean, then this is also possible through javax.faces.bean.ManagedProperty (note that the bean can only be @RequestScoped!):
@ManagedProperty("#{request.requestURL}")
private StringBuffer url; // +setter
@ManagedProperty("#{request.requestURI}")
private String uri; // +setter
public void someMethod() {
// ...
}
