Pragmatically add Spring MVC Controllers

1_TestController.java

package foobar;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class TestController {
	
	@RequestMapping("/test/foobar")
	public String getSecureTest(Model model) {
		return "test";
	}
}

2_ExampleConfig.java

import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;

import org.springframework.beans.BeansException;
import org.springframework.beans.factory.annotation.Autowire;
import org.springframework.beans.factory.config.BeanDefinition;
import org.springframework.beans.factory.config.ConfigurableListableBeanFactory;
import org.springframework.beans.factory.support.BeanDefinitionRegistry;
import org.springframework.beans.factory.support.BeanDefinitionRegistryPostProcessor;
import org.springframework.beans.factory.support.RootBeanDefinition;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;

import foobar.TestController;

@Configuration
public class ExampleConfig implements BeanDefinitionRegistryPostProcessor{

	@Override
	public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) throws BeansException {}

	@Override
	public void postProcessBeanDefinitionRegistry(BeanDefinitionRegistry registry) throws BeansException {
		BeanDefinition beanDefinition = new RootBeanDefinition(TestController.class, Autowire.BY_TYPE.value(), true);
		registry.registerBeanDefinition("testController", beanDefinition);
	}
