Class RoleVoter

java.lang.Object
org.springframework.security.access.vote.RoleVoter
All Implemented Interfaces:
AccessDecisionVoter<Object>
Direct Known Subclasses:
RoleHierarchyVoter
@Deprecated public class RoleVoter extends Object implements AccessDecisionVoter<Object>
Deprecated.
Use AuthorityAuthorizationManager instead
Votes if any ConfigAttribute.getAttribute() starts with a prefix indicating that it is a role. The default prefix string is ROLE_, but this may be overridden to any value. It may also be set to empty, which means that essentially any attribute will be voted on. As described further below, the effect of an empty prefix may not be quite desirable.

Abstains from voting if no configuration attribute commences with the role prefix. Votes to grant access if there is an exact matching GrantedAuthority to a ConfigAttribute starting with the role prefix. Votes to deny access if there is no exact matching GrantedAuthority to a ConfigAttribute starting with the role prefix.

An empty role prefix means that the voter will vote for every ConfigAttribute. When there are different categories of ConfigAttributes used, this will not be optimal since the voter will be voting for attributes which do not represent roles. However, this option may be of some use when using pre-existing role names without a prefix, and no ability exists to prefix them with a role prefix on reading them in, such as provided for example in JdbcDaoImpl.

All comparisons and prefixes are case sensitive.

      Deprecated.

    • setRolePrefix

      public void setRolePrefix(String rolePrefix)

      Allows the default role prefix of ROLE_ to be overridden. May be set to an empty value, although this is usually not desirable.
      Parameters:
      rolePrefix - the new prefix

    • supports

      public boolean supports(ConfigAttribute attribute)
      Deprecated.
      Description copied from interface: AccessDecisionVoter
      Indicates whether this AccessDecisionVoter is able to vote on the passed ConfigAttribute.

      This allows the AbstractSecurityInterceptor to check every configuration attribute can be consumed by the configured AccessDecisionManager and/or RunAsManager and/or AfterInvocationManager.

      Specified by:
      supports in interface AccessDecisionVoter<Object>
      Parameters:
      attribute - a configuration attribute that has been configured against the AbstractSecurityInterceptor
      Returns:
      true if this AccessDecisionVoter can support the passed configuration attribute

    • supports

      public boolean supports(Class<?> clazz)
      Deprecated.
      This implementation supports any type of class, because it does not query the presented secure object.
      Specified by:
      supports in interface AccessDecisionVoter<Object>
      Parameters:
      clazz - the secure object
      Returns:
      always true

    • vote

      public int vote(Authentication authentication, Object object, Collection<ConfigAttribute> attributes)
      Deprecated.
      Description copied from interface: AccessDecisionVoter
      Indicates whether or not access is granted.

      The decision must be affirmative (ACCESS_GRANTED), negative ( ACCESS_DENIED) or the AccessDecisionVoter can abstain ( ACCESS_ABSTAIN) from voting. Under no circumstances should implementing classes return any other value. If a weighting of results is desired, this should be handled in a custom AccessDecisionManager instead.

      Unless an AccessDecisionVoter is specifically intended to vote on an access control decision due to a passed method invocation or configuration attribute parameter, it must return ACCESS_ABSTAIN. This prevents the coordinating AccessDecisionManager from counting votes from those AccessDecisionVoters without a legitimate interest in the access control decision.

      Whilst the secured object (such as a MethodInvocation) is passed as a parameter to maximise flexibility in making access control decisions, implementing classes should not modify it or cause the represented invocation to take place (for example, by calling MethodInvocation.proceed()).

      Specified by:
      vote in interface AccessDecisionVoter<Object>
      Parameters:
      authentication - the caller making the invocation
      object - the secured object being invoked
      attributes - the configuration attributes associated with the secured object
      Returns:
      either AccessDecisionVoter.ACCESS_GRANTED, AccessDecisionVoter.ACCESS_ABSTAIN or AccessDecisionVoter.ACCESS_DENIED
