Method Details

createExpressionMessageMetadataSource

public static MessageSecurityMetadataSource createExpressionMessageMetadataSource(LinkedHashMap<MessageMatcher<?>,String> matcherToExpression)

Deprecated.

Create a MessageSecurityMetadataSource that uses MessageMatcher mapped to Spring Expressions. Each entry is considered in order and only the first match is used. For example:

     LinkedHashMap<MessageMatcher<?>,String> matcherToExpression = new LinkedHashMap<MessageMatcher<Object>,String>();
     matcherToExpression.put(new SimDestinationMessageMatcher("/public/**"), "permitAll");
     matcherToExpression.put(new SimDestinationMessageMatcher("/admin/**"), "hasRole('ROLE_ADMIN')");
     matcherToExpression.put(new SimDestinationMessageMatcher("/topics/{name}/**"), "@someBean.customLogic(authentication, #name)");
     matcherToExpression.put(new SimDestinationMessageMatcher("/**"), "authenticated");

     MessageSecurityMetadataSource metadataSource = createExpressionMessageMetadataSource(matcherToExpression);
 

If our destination is "/public/hello", it would match on "/public/**" and on "/**". However, only "/public/**" would be used since it is the first entry. That means that a destination of "/public/hello" will be mapped to "permitAll".

For a complete listing of expressions see MessageSecurityExpressionRoot

Parameters:

matcherToExpression - an ordered mapping of MessageMatcher to Strings that are turned into an Expression using AbstractSecurityExpressionHandler.getExpressionParser()

Returns:

the MessageSecurityMetadataSource to use. Cannot be null.

handler - the SecurityExpressionHandler to use

Returns:
