java.lang.Object
  org.springframework.security.web.access.intercept.DefaultFilterInvocationSecurityMetadataSource

All Implemented Interfaces:

AopInfrastructureBean, SecurityMetadataSource, FilterInvocationSecurityMetadataSource

Direct Known Subclasses:

ExpressionBasedFilterInvocationSecurityMetadataSource

public class DefaultFilterInvocationSecurityMetadataSource
extends Object
implements FilterInvocationSecurityMetadataSource

Default implementation of FilterInvocationDefinitionSource.

Stores an ordered map of RequestMatchers to ConfigAttribute collections and provides matching of FilterInvocations against the items stored in the map.

The order of the RequestMatchers in the map is very important. The first one which matches the request will be used. Later matchers in the map will not be invoked if a match has already been found. Accordingly, the most specific matchers should be registered first, with the most general matches registered last.

The most common method creating an instance is using the Spring Security namespace. For example, the pattern and access attributes of the <intercept-url> elements defined as children of the <http> element are combined to build the instance used by the FilterSecurityInterceptor.

Constructor Detail

DefaultFilterInvocationSecurityMetadataSource

public DefaultFilterInvocationSecurityMetadataSource(LinkedHashMap<RequestMatcher,Collection<ConfigAttribute>> requestMap)

Sets the internal request map from the supplied map. The key elements should be of type RequestMatcher, which. The path stored in the key will depend on the type of the supplied UrlMatcher.

Parameters:

requestMap - order-preserving map of request definitions to attribute lists

Method Detail

getAllConfigAttributes

public Collection<ConfigAttribute> getAllConfigAttributes()

Description copied from interface: SecurityMetadataSource

If available, returns all of the ConfigAttributes defined by the implementing class.

This is used by the AbstractSecurityInterceptor to perform startup time validation of each ConfigAttribute configured against it.

Specified by:

getAllConfigAttributes in interface SecurityMetadataSource

Returns:

the ConfigAttributes or null if unsupported

getAttributes

public Collection<ConfigAttribute> getAttributes(Object object)

Description copied from interface: SecurityMetadataSource

Accesses the ConfigAttributes that apply to a given secure object.

Specified by:

getAttributes in interface SecurityMetadataSource

Parameters:

object - the object being secured

Returns:

the attributes that apply to the passed in secured object. Should return an empty collection if there are no applicable attributes.

supports

public boolean supports(Class<?> clazz)

Description copied from interface: SecurityMetadataSource

Indicates whether the SecurityMetadataSource implementation is able to provide ConfigAttributes for the indicated secure object type.

Specified by:

supports in interface SecurityMetadataSource

Parameters:

clazz - the class that is being queried

Returns:

true if the implementation can process the indicated class
