Question

我用Spring框架4.0.2 + Spring MVC构建我的应用程序，JavaMelody用于监控应用程序性能。使用LoginInterceptor，没有登录会话的每个其他请求URL将被重定向到登录页面，但javamelody仪表板除外：mydomain.com/monitoring; 我需要用Filter替换Interceptor吗？因为RequestParameterFilter中设置的断点适用于/ monitoring ... 请帮帮我，谢谢。

代码FYI。

LoginInterceptor.java

public class LoginInterceptor implements HandlerInterceptor {

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

        User user = (User)request.getSession().getAttribute(BmcConstants.LOGIN_USER);
        if(user==null){
            response.sendRedirect(request.getContextPath() + "/login");
            return false;
        }

        return true;
    }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response,
            Object handler, Exception exp)
            throws Exception {
    }

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

}

Answer 1

尝试在web.xml中添加旋律过滤器：

<filter>
    <filter-name>monitoring</filter-name>
    <filter-class>net.bull.javamelody.MonitoringFilter</filter-class>
    <async-supported>true</async-supported>
</filter>

<filter-mapping>
    <filter-name>monitoring</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

spring mvc interceptor不能与javamelody一起工作
