Interface SystemAuthenticator

All Known Implementing Classes:

SystemAuthenticatorImpl

public interface SystemAuthenticator

Provides ad-hoc authentication, i.e. allows you to execute code on behalf of the 'system' or a specified user.

Example usage:

     authenticator.runWithSystem(() -> {
         // valid current thread's authentication presents here
     });
 

or

     authenticator.begin();
     try {
         // valid current thread's authentication presents here
     } finally {
         authenticator.end();
     }

Method Details

begin

org.springframework.security.core.Authentication begin(@Nullable
 String login)

Begins an authenticated code block.
Saves the current thread session on a stack to get it back on end(). Subsequent end() method must be called in "finally" section.

Parameters:

login - user login. If null, authenticates as the 'system' user.

Returns:

populated Authentication object

begin

org.springframework.security.core.Authentication begin()

Authenticate as the 'system' user.
Same as begin(String) with null parameter.

end

void end()

End of an authenticated code block.
The previous session (or null) is set to security context. Must be called in "finally" section of a try/finally block.

withUser

<T> T withUser(@Nullable
 String login,
 SystemAuthenticator.AuthenticatedOperation<T> operation)

Execute code on behalf of the specified user and return a result.

Parameters:

login - user login. If null, the system session is used.

operation - code to execute

Returns:

result of the execution

runWithUser

void runWithUser(@Nullable
 String login,
 Runnable operation)

Execute code on behalf of the specified user.

Parameters:

login - user login. If null, the system session is used.

operation - code to execute

withSystem

<T> T withSystem(SystemAuthenticator.AuthenticatedOperation<T> operation)

Execute code as the 'system' user and return a result.

Parameters:

operation - code to execute

Returns:

result of the execution

runWithSystem

void runWithSystem(Runnable operation)

Execute code as the 'system' user.

Parameters:

operation - code to execute
