Example 4 with Interceptor

use of org.axe.interface_.mvc.Interceptor in project Axe by DongyuCai.

the class InterceptorHelper method init.

@Override
public void init() {
    synchronized (this) {
        INTERCEPTOR_MAP = new HashMap<>();
        Set<Class<?>> interceptorClassSet = ClassHelper.getClassSetBySuper(Interceptor.class);
        if (CollectionUtil.isNotEmpty(interceptorClassSet)) {
            for (Class<?> interceptorClass : interceptorClassSet) {
                Interceptor interceptor = ReflectionUtil.newInstance(interceptorClass);
                INTERCEPTOR_MAP.put(interceptor.getClass(), interceptor);
            }
        }
    }
}
