ActionMatcher

如何自定义 ActionMatcher (SPI)

参考 PathActionMatcher

class CustomConditionMatcherFactory : ConditionMatcherFactory {
    companion object {
        const val TYPE = "[CustomConditionType]"
    }

    override val type: String
        get() = TYPE

    override fun create(configuration: Configuration): ConditionMatcher {
        return CustomConditionMatcher(configuration)
    }
}
class CustomConditionMatcher(configuration: Configuration) :
    AbstractConditionMatcher(CustomConditionMatcherFactory.TYPE, configuration) {

    override fun internalMatch(request: Request, securityContext: SecurityContext): Boolean {
        //Custom matching logic
    }
}
