本文介绍了一个具体的Spring MVC拦截器实现案例，展示了如何通过自定义拦截器类来控制请求流程，并配置了全局路径拦截规则。此外，还说明了如何排除不需要拦截的路径。

public class LoginIntercetor implements HandlerInterceptor{

    @Override
    public boolean preHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o) throws Exception {
        System.out.println("进入拦截器");
        return true;
    }

    @Override
    public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, ModelAndView modelAndView) throws Exception {
        System.out.println("postHandler");
    }

    @Override
    public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) throws Exception {
        System.out.println("处理完成");
    }
}

    <!--配置拦截器-->
    <mvc:interceptors>
        <mvc:interceptor>
            <mvc:mapping path="/**"/>
            <bean class="com.core.LoginIntercetor"/>
            <!--那些类不进入拦截器-->
            <!--<mvc:exclude-mapping path=""></mvc:exclude-mapping>-->
        </mvc:interceptor>
        <mvc:interceptor>
            <mvc:mapping path="/**"/>
            <bean class="com.core.LoginIntercetor"/>
        </mvc:interceptor>
    </mvc:interceptors>
