将Spring HandlerInterceptor仅绑定到一个控制器 [英] bind Spring HandlerInterceptor only to one controller

问题描述

使用Spring 3.0.2.RELEASE。我在com.myCompany包中有2个控制器。控制器通过组件扫描激活

Using Spring 3.0.2.RELEASE. I'm having 2 Controllers in package com.myCompany. The Controllers are activated via Component-scan

<context:component-scan base-package="com.myCompany" />

然后我通过

<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
   <property name="interceptors">
     <list>
       <ref bean="myInterceptor"/>
     </list>
   </property>
 </bean>

如何将拦截器仅绑定到一个特定的控制器或控制器内的某些方法？
背景：我想检查它包含某些参数的URL

How can i bind the interceptor to only one specific Controller or to only certain methods inside a Controller? Background: I want to inspect the URL that it contains certain parameters

推荐答案

当您将拦截器注入 HandlerMapping bean时，这些拦截器将应用于由 HandlerMapping映射的每个处理程序。这在预注释时很好，因为你只需要配置多个 HandlerMapping bean。但是，使用注释时，我们往往会有一个 DefaultAnnotationHandlerMapping 来映射所有内容，因此这个模型不起作用。

When you inject interceptors into a HandlerMapping bean, those interceptors apply to every handler mapped by that HandlerMapping. That was fine in the pre-annotation days, since you'd just have configure multiple HandlerMapping beans. However, with annotations, we tend to have a single DefaultAnnotationHandlerMapping that maps everything, so this model doesn't work.

解决方案是使用< mvc：interceptors> ，您可以显式地将路径映射到拦截器bean。请参阅 docs ，这个例子：

The solution is to use <mvc:interceptors>, where you explicitly map paths to interceptor beans. See the docs, and this example:

<mvc:interceptors>
    <mvc:interceptor>
        <mvc:mapping path="/secure/*"/>
        <bean class="org.example.SecurityInterceptor" />
    </mvc:interceptor>
</mvc:interceptors>
