AbstractControllerUrlHandlerMapping类简介说明

下文讲述AbstractControllerUrlHandlerMapping类的简介说明，如下所示:

AbstractControllerUrlHandlerMapping的功能:
    此类将实现Controller接口或注释了@Controller的bean作为Handler
   并且可以通过设置excludedClasses和excludedPackages
    将不包含的bean或不包含的包下的所有bean排除在外

determineUrlsForHandler()方法的功能

determineUrlsForHandler() 获取bean并完成beanName和beanClass的对应关系

@Override  
protected String[] determineUrlsForHandler(String beanName) {  
    Class beanClass = getApplicationContext().getType(beanName);  
    //判断是不是支持的类型  
    if (isEligibleForMapping(beanName, beanClass)) {  
        //模板方法，在子类实现  
        return buildUrlsForHandler(beanName, beanClass);  
    }  
    else {  
        return null;  
    }  
}

setIncludeAnnotatedControllers() 配置操作

public void setIncludeAnnotatedControllers(boolean includeAnnotatedControllers) {  
	this.predicate = (includeAnnotatedControllers ?  new AnnotationControllerTypePredicate() : new ControllerTypePredicate());  
}  
  
public void setExcludedPackages(String... excludedPackages) {  
	this.excludedPackages = (excludedPackages != null) ?  new HashSet(Arrays.asList(excludedPackages)) : new HashSet();  
}  

public void setExcludedClasses(Class... excludedClasses) {  
	this.excludedClasses = (excludedClasses != null) ?  new HashSet>(Arrays.asList(excludedClasses)) : new HashSet>();  
}
