Exact RequestMapping with Spring

Question

I have the following in Spring

@RequestMapping("/hello")

However Spring automatically adds mappings for /hello/ as well as /hello.*. How do I do an exact URL match?

Only /hello should work, anything else should 404

Answer 1

Turning off suffix matching (useSuffixPatternMatch) on RequestMappingHandlerMapping will solve your problem, but doing so is actually not so easy, if you use <mvc:annotation-driven/> in your configuration (instead of manually wiring all the necessary infrastructure beans). In this case defining an additional bean of type RequestMappingHandlerMapping won't have any effect.

You have two options:

1. Remove <mvc:annotation-driven/> expanding it to an equivalent set of bean definitions where you can apply the useSuffixPatternMatch setting.

2. Keep <mvc:annotation-driven/> as it is, and use a much easier workaround described here: https://jira.springsource.org/browse/SPR-9371. This basically adds a BeanPostProcessor which retrieves the RequestMappingHandlerMapping bean created by the mvc namespace, and sets the above mentioned flag.

There is also another ticket requesting that it should be much easier to customize the RequestMappingHandlerMapping created by the mvc namespace without applying hacks like above. You can consider voting on this ticket.

If you are using version 3.1/3.2, then you can try this without commenting or deleting

Write a post processor

public class MvcConfigurationPostProcessor implements BeanPostProcessor, PriorityOrdered {

   @Override
   public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException {
      if (bean instanceof RequestMappingHandlerMapping) {
         ((RequestMappingHandlerMapping) bean).setUseSuffixPatternMatch(false);
      }
      return bean;
   }

   @Override
   public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {
      return bean;
   }

   @Override
   public int getOrder() {
      return PriorityOrdered.HIGHEST_PRECEDENCE;
   }

}

use the above post processor in xml config.

<bean class="com.beanprocbug.melia.MvcConfigurationPostProcessor" />
<mvc:annotation-driven />
