Identifying the currently logged in user.

[spierepf]

I am writing a custom data source that needs to identify the currently logged in user in order to correctly determine which database to connect to.

How can I determine the currently logged in user from Java?

Thanks,

Peter.

Hi,

 

Try what you see below, you'll have to put into the java class that makes sense in your case.

Code:

// Add these imports to your Java class



import com.jaspersoft.jasperserver.api.metadata.user.domain.impl.client.MetadataUserDetails;

import org.springframework.security.Authentication;

import org.springframework.security.context.SecurityContextHolder;



// Put this in the method you need the username



String username; // will store logged-in username here



// Using Spring to pull authentication info

Authentication auth = SecurityContextHolder.getContext().getAuthentication();

if (auth != null && auth.getPrincipal() != null) {

    username = ((MetadataUserDetails) auth.getPrincipal()).getUsername();

}



// Do what you need to do here

Thanks gdmoreno,

 

I was actually hoping for an instance of the:

 

com.jaspersoft.jasperserver.api.metadata.user.domain.User

 

class.

 

Any ideas?

 

Peter.

Fortunately, it turns out that com.jaspersoft.jasperserver.api.metadata.user.domain.User is an interface, and com.jaspersoft.jasperserver.api.metadata.user.domain.impl.client.MetadataUserDetails implements that interface.

So all you have to do is import that User interface and change the code only a little, like what's below.

Code:

// Import this interface, keep the other importsimport com.jaspersoft.jasperserver.api.metadata.user.domain.User;// Find this line: // username = ((MetadataUserDetails) auth.getPrincipal()).getUsername();// and put this in its placeusername = ((User) auth.getPrincipal()).getUsername();

Worked like a charm!

 

Awesome, thanks so much.

Is there a way that we could get the username of the user who logged into the JasperServer

Thanks

I was trying to invoke the username in the follwoing way:

 

Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal();

String username = principal.toString();

 

Now I can see username contains MetadataUserDetails, how can I grab the currently logged in user name?
