== Use PathPatternMessageMatcher by Default

In Spring Security 7, `SimpDestMessageMatcher` is no longer supported and will use `PathPatternMessageMatcher` by default.

To check how prepared you are for this change, you can publish this bean:

[tabs]
======
Java::
+
[source,java,role="primary"]
----
@Bean
PathPatternMessageMatcherBuilderFactoryBean messageMatcherBuilder() {
	return new PathPatternMessageMatcherBuilderFactoryBean();
}
----

Kotlin::
+
[source,kotlin,role="secondary"]
----
@Bean
fun messageMatcherBuilder(): PathPatternMessageMatcherBuilderFactoryBean {
    return PathPatternMessageMatcherBuilderFactoryBean()
}
----

Xml::
+
[source,xml,role="secondary"]
----
<b:bean class="org.springframework.security.config.web.messaging.PathPatternMessageMatcherBuilderFactoryBean"/>
----
======

This will tell the Spring Security DSL to use `PathPatternMessageMatcher` for all message matchers that it constructs.
