The predicate bean named shibboleth.BiConditions.Scripted executes a JSR-223 scriptlet against 2 arbitrary inputs to produce a true/false result.
Configuration
A Scripted BiPredicate is instantiated using one of two static factory methods (rather than created directly by invoking a Java constructor), so they have a different syntax in Spring. You can refer to the javadoc for complete details.
inlineScript
If provided with one parameter, this is the script to be executed. If two parameters are the provided, then the first is the name of the (installed) JSR-223 lanuage and the second is the script.
<bean id="MyCondition" parent="shibboleth.BiConditions.Scripted" factory-method="inlineScript"
p:customObject-ref="MyCustomObject" p:hideExceptions="true">
<constructor-arg>
<value>
<![CDATA[
// Your script here
true;
]]>
</value>
</constructor-arg>
</bean>
resourceScript
If provided with one parameter this is the location (usually the file name) of the resource (file) containing the script. If two parameters are provided, the the first is the name of the (installed) JSR-223 lanuage and the second is the location.
<bean id="MyCondition" parent="shibboleth.BiConditions.Scripted" factory-method="resourceScript"
c:_0="%{idp.home}/conf/script.js" c:_1="javascript" />
