java - Spring 拦截器不发射

Question

我正在尝试按照此处所述实现日志记录 http://www.vaannila.com/spring/spring-interceptor.html

这是处理程序映射文件:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:oxm="http://www.springframework.org/schema/oxm"
xsi:schemaLocation="http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-3.0.xsd
        http://www.springframework.org/schema/oxm 
        http://www.springframework.org/schema/oxm/spring-oxm-3.0.xsd">

    <bean id="beanNameResolver" 
        class="org.springframework.web.servlet.view.BeanNameViewResolver"/>

    <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping" 
    p:interceptors-ref="loggerInterceptor" />
    <context:component-scan base-package="com.audiClave.controllers" />
    <bean id="loggerInterceptor" class="com.audiClave.controllers.LoggerInterceptor" /> 

</beans>

这是拦截器:

package com.audiClave.controllers;

...

public class LoggerInterceptor extends HandlerInterceptorAdapter {

static Logger logger = Logger.getLogger(LoggerInterceptor.class);

static{
    BasicConfigurator.configure();
            logger.setLevel((Level)Level.INFO);
}

@Override
public boolean preHandle(HttpServletRequest request,
        HttpServletResponse response, Object handler) throws Exception {
    logger.info("Before handling the request");
    return super.preHandle(request, response, handler);
}

@Override
public void postHandle(HttpServletRequest request,
        HttpServletResponse response, Object handler,
        ModelAndView modelAndView) throws Exception {
    logger.info("After handling the request");
    super.postHandle(request, response, handler, modelAndView);
}

@Override
public void afterCompletion(HttpServletRequest request,
        HttpServletResponse response, Object handler, Exception ex)
        throws Exception {
    logger.info("After rendering the view");
    super.afterCompletion(request, response, handler, ex);
}
}

控制台中显示以下消息:

Mapping [/REST/en/actions] to HandlerExecutionChain with handler [com.audiClave.controllers.RestController@18f110d] and 3 interceptors

调用 Controller ，但不调用拦截器。 为什么拦截器不会被调用？我使用的是Spring 3.0.5

我尝试在所有事件中放置调试断点，但没有一个事件被触发。已将日志记录设置为 INFO 但仍然没有输出。

由于以下日志语句，loggerInterceptor 被拾取:

2011-06-22 21:11:39,828 [ContainerBackgroundProcessor[StandardEngine[Catalina]]] INFO  org.springframework.beans.factory.support.DefaultListableBeanFactory - Destroying singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@f2ea42: defining beans [beanNameResolver,org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping#0,baseController,restController,org.springframework.context.annotation.internalConfigurationAnnotationProcessor,org.springframework.context.annotation.internalAutowiredAnnotationProcessor,org.springframework.context.annotation.internalRequiredAnnotationProcessor,org.springframework.context.annotation.internalCommonAnnotationProcessor,loggerInterceptor]; root of factory hierarchy

也许该类在列表中的位置不正确？？

不确定这些是否有帮助，但尝试使用

• org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping 而不是 DefaultAnnotationHandlerMapping 和

• 替换 schemaLocation 以匹配您的 Spring 版本:

  ... http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
