org.springframework.security.config

Class SecurityNamespaceHandler

java.lang.Object

org.springframework.security.config.SecurityNamespaceHandler

All Implemented Interfaces:

org.springframework.beans.factory.xml.NamespaceHandler

public final class SecurityNamespaceHandler
extends Object
implements org.springframework.beans.factory.xml.NamespaceHandler

Die Klasse überschreibt die eigentliche Klasse org.springframework.security.config.SecurityNamespaceHandler, so dass anstatt des der Klasse org.springframework.security.config.ldap.LdapUserServiceBeanDefinitionParser zum Parsen des Elements "security" mit dem Namespace http://www.springframework.org/schema/security die eigene Implementierung de.fraunhofer.igd.klarschiff.service.security.LdapServerBeanDefinitionParser verwendet wird. Parses elements from the "security" namespace (http://www.springframework.org/schema/security).

Since:

2.0

Method Detail

parse

public org.springframework.beans.factory.config.BeanDefinition parse(Element element,
                                                                     org.springframework.beans.factory.xml.ParserContext pc)

Specified by:

parse in interface org.springframework.beans.factory.xml.NamespaceHandler

decorate

public org.springframework.beans.factory.config.BeanDefinitionHolder decorate(Node node,
                                                                              org.springframework.beans.factory.config.BeanDefinitionHolder definition,
                                                                              org.springframework.beans.factory.xml.ParserContext pc)

Specified by:

decorate in interface org.springframework.beans.factory.xml.NamespaceHandler

reportUnsupportedNodeType

private void reportUnsupportedNodeType(String name,
                                       org.springframework.beans.factory.xml.ParserContext pc,
                                       Node node)

reportMissingWebClasses

private void reportMissingWebClasses(String nodeName,
                                     org.springframework.beans.factory.xml.ParserContext pc,
                                     Node node)

init

public void init()

Specified by:

init in interface org.springframework.beans.factory.xml.NamespaceHandler

loadParsers

private void loadParsers()

In der Methode wird als Parser für das Element ldap-server die eigene Implementierung de.fraunhofer.igd.klarschiff.service.security.LdapServerBeanDefinitionParser statt die Implementierung org.springframework.security.config.ldap.LdapUserServiceBeanDefinitionParser registiert.

namespaceMatchesVersion

private boolean namespaceMatchesVersion(Element element)

Check that the schema location declared in the source file being parsed matches the Spring Security version. The old 2.0 schema is not compatible with the 3.1 parser, so it is an error to explicitly use 2.0.

There are also differences between 3.0 and 3.1 which are sufficient that we report using 3.0 as an error too. It might be an error to declare spring-security.xsd as an alias, but you are only going to find that out when one of the sub parsers breaks.

Parameters:

element - the element that is to be parsed next

Returns:

true if we find a schema declaration that matches

matchesVersionInternal

private boolean matchesVersionInternal(Element element)
