public class SimpleAccountRealm
extends AuthorizingRealm

A simple implementation of the Realm interface that uses a set of configured user accounts and roles to support authentication and authorization. Each account entry specifies the username, password, and roles for a user. Roles can also be mapped to permissions and associated with users.

User accounts and roles are stored in two Maps in memory, so it is expected that the total number of either is not sufficiently large.

0.1

                                              throws AuthenticationException

Description copied from class: AuthenticatingRealm

Retrieves authentication data from an implementation-specific datasource (RDBMS, LDAP, etc) for the given authentication token.

For most datasources, this means just 'pulling' authentication data for an associated subject/user and nothing more and letting Shiro do the rest. But in some systems, this method could actually perform EIS specific log-in logic in addition to just retrieving data - it is up to the Realm implementation.

A null return value means that no account could be associated with the specified token.

Specified by:

doGetAuthenticationInfo in class AuthenticatingRealm

Parameters:

token - the authentication token containing the user's principal and credentials.

Returns:

an AuthenticationInfo object containing account data resulting from the authentication ONLY if the lookup is successful (i.e. account exists and is valid, etc.)

Throws:

AuthenticationException - if there is an error acquiring data or performing realm-specific authentication logic for the specified token

doGetAuthorizationInfo

protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals)

Description copied from class: AuthorizingRealm

Retrieves the AuthorizationInfo for the given principals from the underlying data store. When returning an instance from this method, you might want to consider using an instance of SimpleAuthorizationInfo, as it is suitable in most cases.

Specified by:

doGetAuthorizationInfo in class AuthorizingRealm

Parameters:

principals - the primary identifying principals of the AuthorizationInfo that should be retrieved.

Returns:

the AuthorizationInfo associated with this principals.
