Usage

From source file:io.neba.core.mvc.MvcContext.java

/**
 * Registers the custom argument resolvers if a {@link RequestMappingHandlerAdapter}
 * is present in the factory./*from  w ww. j  av  a2s.  c o  m*/
 */
private void registerCustomArgumentResolvers() {
    RequestMappingHandlerAdapter requestMappingHandlerAdapter = this.factory
            .getBean(RequestMappingHandlerAdapter.class);

    if (requestMappingHandlerAdapter != null) {
        HandlerMethodArgumentResolverComposite argumentResolvers = requestMappingHandlerAdapter
                .getArgumentResolvers();

        if (argumentResolvers == null) {
            throw new IllegalStateException("No argument resolvers found in " + requestMappingHandlerAdapter
                    + ". It appears the handler was not initialized by the application context.");
        }

        // Add Sling-specific argument resolvers first
        List<HandlerMethodArgumentResolver> resolvers = new LinkedList<HandlerMethodArgumentResolver>();
        resolvers.add(new RequestPathInfoArgumentResolver());
        resolvers.add(new ResourceResolverArgumentResolver());
        resolvers.add(new ResourceParamArgumentResolver());

        // Subsequently add all existing argument resolvers (they are order-sensitive, ending with a catch-all resolver,
        // thus the custom resolvers have to go first)
        resolvers.addAll(argumentResolvers.getResolvers());
        requestMappingHandlerAdapter.setArgumentResolvers(resolvers);
    }
}
