Java 未调用Spring拦截器

我正在尝试构建一个Spring应用程序，我想记录所有请求/响应。我找到了一些例子，但没有一个有用。我正在尝试创建一个拦截器，该拦截器将记录我需要的所有信息，但从未调用过拦截器。
有人能解释一下我的拦截器为什么不工作吗？

我的web.xml文件

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="
        http://java.sun.com/xml/ns/javaee
        http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0">

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring/business-config.xml</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <servlet>
        <servlet-name>mvc-dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    </servlet>

    <servlet-mapping>
        <servlet-name>mvc-dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

编辑：
我通过移动其中所有与mvc相关的内容创建了

mvc dispatcher servlet.xml

。但如果没有

，它就无法工作，拦截器仍然是个问题。

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <mvc:default-servlet-handler/>
    <mvc:annotation-driven/>
    <mvc:interceptors>
        <mvc:interceptor>
            <mvc:mapping path="/*"/>
            <bean class="ltp.core.security.RequestProcessingInterceptor"/>
        </mvc:interceptor>
    </mvc:interceptors>
</beans>

老问题，但黄金问题，我在spring MVC中遇到了相同的拦截器问题，只是没有调用它们。 找到解决方案后，你应该检查几件事。首先，确保将

放入dispatcher-servlet.xml（而不是applicationContext.xml）中。扩展

HandlerInterceptorAdapter

的拦截器类不需要任何类似Bean的注释，如@Component（因为您是在xml配置中进行此操作的）

一件重要的事情是检查：

xmlns:mvc=”http://www.springframework.org/schema/mvc“

它不应该是Intellij或其他东西自动添加的

/schema/c

或

/schema/p

这些是我的代码，用于检查所有内容：

public class MyCustomInterceptor extends HandlerInterceptorAdapter {


@Autowired
private IpClientService ipClientService;


@Override
public boolean preHandle(HttpServletRequest request, 
HttpServletResponse response, Object handler) throws Exception {

    // ------ your code here --------

    String reqUri = request.getRequestURI();
    String serviceName = reqUri.substring(reqUri.lastIndexOf("/") +1, reqUri.length());

    ......



    return super.preHandle(request, response, handler);
}

@Override
public void postHandle(HttpServletRequest request,
                       HttpServletResponse response, Object handler,
                       ModelAndView modelAndView) throws Exception {

    super.postHandle(request, response, handler, modelAndView);
}
}

my dispatcher-servlet.xml：

哪种配置？

business config.xml

或

mvc dispatcher servlet.xml

的记录器级别设置为log INFO level？@M.Deinum这是一个business config.xml。@AmitParashar记录器设置正确。我也有一个断点->没有调用拦截器。好的。请尝试让我知道。我可以问一下为什么在dispatcher-servlet.xml中使用名称空间mcv和avc，而这两个名称空间都指向“@user3366706”吗？你是对的，名称空间用于解决xml文件中的名称冲突。在这种情况下，两者都是一样的，我随机使用它们，没什么大不了的。如你所见，我也编辑了代码。谢谢
