想法是好的，如何实现这一套流程呢？首先要解决以下问题。

　　1、定义的接口不能被springmvc扫描到。

　　2、接口定义还是要按照@RequestMaping规则方式编写，这样才能减少开发量并且能被RequestMappingHandlerMapping处理。

　　3、如何自动注册url->handler到SimpleUrlHandlerMapping中去。

　　对于上面需要实现的，首先要了解一些springmvc相关源码。

v　　RequestMappingHandlerMapping初始化method mapping

/**  * Scan beans in the ApplicationContext, detect and register handler methods.  * @see #isHandler(Class)  * @see #getMappingForMethod(Method, Class)  * @see #handlerMethodsInitialized(Map)  */protected void initHandlerMethods() {     if (logger.isDebugEnabled()) {         logger.debug("Looking for request mappings in application context: " + getApplicationContext());     }     String[] beanNames = (this.detectHandlerMethodsInAncestorContexts ?             BeanFactoryUtils.beanNamesForTypeIncludingAncestors(getApplicationContext(), Object.class) :             getApplicationContext().getBeanNamesForType(Object.class));      for (String beanName : beanNames) {         if (!beanName.startsWith(SCOPED_TARGET_NAME_PREFIX)) {             Class<?> beanType = null;             try {                 beanType = getApplicationContext().getType(beanName);             }             catch (Throwable ex) {                 // An unresolvable bean type, probably from a lazy bean - let's ignore it.                if (logger.isDebugEnabled()) {                     logger.debug("Could not resolve target class for bean with name '" + beanName + "'", ex);                 }             }             if (beanType != null && isHandler(beanType)) {                 detectHandlerMethods(beanName);             }         }     }     handlerMethodsInitialized(getHandlerMethods()); }

 　　isHandler方法【判断方法是不是一个具体handler】逻辑如下

protected boolean isHandler(Class<?> beanType) {     return (AnnotatedElementUtils.hasAnnotation(beanType, Controller.class) ||             AnnotatedElementUtils.hasAnnotation(beanType, RequestMapping.class)); }

　　所以我们定义的开关接口为了不被springmvc扫描到，直接去掉类注释上的@Controller注解和@RequestMapping注解就好了，如下。

@Component @ResponseBody public class CommonsStateController {     @GetMapping("/url1")     public String handleUrl1()  {       return null;     }
