ProjectStage and ResourceDependency
Hello list,
Is it possible to have different ResourceDependencies for components depending on the Project Stage?
Example - when the project is in Development Stage the context param javax.faces.PROJECT_STAGE is set to Development
<context-param>
<param-name>javax.faces.PROJECT_STAGE</param-name>
<param-value>Development</param-value>
</context-param>
I want this:
@ResourceDependencies({
@ResourceDependency(name="jquery-ui.css",library="css"),
@ResourceDependency(name="jquery.js",library="js",target="head"),
//@ResourceDependency(name="jquery.min.js",library="js",target="head"),
@ResourceDependency(name="jquery-ui.js",library="js",target="head")
//@ResourceDependency(name="jquery-ui.min.js",library="js",target="head")
})
@FacesComponent("de.example.jsf2.components.Accordion")
public class Accordion extends UIPanel {
But when the Project stage is Test or Production I want this:
@ResourceDependencies({
@ResourceDependency(name="jquery-ui.css",library="css"),
//@ResourceDependency(name="jquery.js",library="js",target="head"),
@ResourceDependency(name="jquery.min.js",library="js",target="head"),
//@ResourceDependency(name="jquery-ui.js",library="js",target="head")
@ResourceDependency(name="jquery-ui.min.js",library="js",target="head")
})@FacesComponent("de.example.jsf2.components.Accordion")
public class Accordion extends UIPanel {
Maybe there is a system in the Resources similar how you can add version numbers.

That's great - you're welcome :)
However, you can cache isDevelopmentStage no matter what ProjectStage
you have. It won't change unless you redeploy your webapp.
Thus I recommend this code:
private Boolean developmentStage = null;
public boolean isDevelopmentStage()
{
if (developmentStage == null)
{
FacesContext facesContext = FacesContext.getCurrentInstance();
developmentStage =
facesContext.isProjectStage(ProjectStage.Development);
}
return developmentStage;
}
This spares you one FacesContext.getCurrentInstance() -->
ThreadLocal.get() invocation per resource creation (in development
stage).

Jakob

AW: ProjectStage and ResourceDependency
Posted by Eisenträger,
Tobias <To...@arag.de>.
Thank you Jacob - that worked great.
Here's the code for reference:
Faces-config.xml:
<application>
<resource-handler>
de.example.jsf2.sample.application.CustomResourceHandler
</resource-handler>
</application>
CustomResourceHandler.java:
package de.example.jsf2.sample.application;
import javax.faces.application.ProjectStage;
import javax.faces.application.Resource;
import javax.faces.application.ResourceHandler;
import javax.faces.application.ResourceHandlerWrapper;
import javax.faces.context.FacesContext;
public class CustomResourceHandler extends ResourceHandlerWrapper {
private ResourceHandler parent = null;
private boolean isDevelopmentStage = true;
public CustomResourceHandler(ResourceHandler parent) {
this.parent = parent;
}
@Override
public ResourceHandler getWrapped() {
return this.parent;
}
@Override
public Resource createResource(String resourceName) {
return super.createResource(takeOutMinIfInDevelopmentmode(resourceName));
}
@Override
public Resource createResource(String resourceName, String libraryName,String contentType) {
return super.createResource(takeOutMinIfInDevelopmentmode(resourceName), libraryName, contentType);
}
@Override
public Resource createResource(String resourceName, String libraryName) {
return super.createResource(takeOutMinIfInDevelopmentmode(resourceName), libraryName);
}
private String takeOutMinIfInDevelopmentmode(String resourceName) {
if(getIsDevelopmentStage()) {
if(resourceName!=null && resourceName.contains(".min")) {
resourceName = resourceName.replace(".min", "");
}
}
return resourceName;
}
private boolean getIsDevelopmentStage() {
if(isDevelopmentStage) {
FacesContext fc = FacesContext.getCurrentInstance();
if (fc.isProjectStage(ProjectStage.Development)) {
// isDevelopmentStage; bleibt true
} else {
isDevelopmentStage = false; // fuehrt logik bis zum naechsten neustart nicht mehr aus
}
}
return isDevelopmentStage;
}
}
So now I can just write:
@ResourceDependencies({
@ResourceDependency(name="jquery-ui.css",library="css"),
@ResourceDependency(name="jquery.min.js",library="js",target="head"),
@ResourceDependency(name="jquery-ui.min.js",library="js",target="head")
})
@FacesComponent("de.example.jsf2.components.Accordion")
public class Accordion extends UIPanel {
.....
}
and it will snip out the .min part when the Stage is Development. Nice feature is that it will only check for the stage one time if we are in Production mode.

Hi Tobias,
You could write your own ResourceHandler (--> ResourceHandlerWrapper)
which wraps the createResource() methods and adjusts the filenames
depending on the current ProjectStage.

Jakob
