Examples with ModelFactory org.springframework.web.method.annotation.ModelFactory used on opensource projects

Example 1 with ModelFactory

use of org.springframework.web.method.annotation.ModelFactory in project spring-framework by spring-projects.

the class RequestMappingHandlerAdapter method getModelFactory.

private ModelFactory getModelFactory(HandlerMethod handlerMethod, WebDataBinderFactory binderFactory) {
    SessionAttributesHandler sessionAttrHandler = getSessionAttributesHandler(handlerMethod);
    Class<?> handlerType = handlerMethod.getBeanType();
    Set<Method> methods = this.modelAttributeCache.get(handlerType);
    if (methods == null) {
        methods = MethodIntrospector.selectMethods(handlerType, MODEL_ATTRIBUTE_METHODS);
        this.modelAttributeCache.put(handlerType, methods);
    }
    List<InvocableHandlerMethod> attrMethods = new ArrayList<>();
    // Global methods first
    this.modelAttributeAdviceCache.forEach((controllerAdviceBean, methodSet) -> {
        if (controllerAdviceBean.isApplicableToBeanType(handlerType)) {
            Object bean = controllerAdviceBean.resolveBean();
            for (Method method : methodSet) {
                attrMethods.add(createModelAttributeMethod(binderFactory, bean, method));
            }
        }
    });
    for (Method method : methods) {
        Object bean = handlerMethod.getBean();
        attrMethods.add(createModelAttributeMethod(binderFactory, bean, method));
    }
    return new ModelFactory(attrMethods, binderFactory, sessionAttrHandler);
}
