Question

我的groovy应用程序的web.xml有一些过滤器，filtermappings，servlet映射，按以下顺序定义的监听器：

<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4">

现在服务器启动正常但是当我点击我的应用程序URL时，我得到一个grails运行时异常，如下所示：

java.lang.ClassCastException: org.springframework.web.context.request.ServletRequestAttributes cannot be cast to org.codehaus.groovy.grails.web.servlet.mvc.GrailsWebRequest

    at org.codehaus.groovy.grails.web.util.WebUtils.retrieveGrailsWebRequest(WebUtils.java:497)

我认为加载过滤器和过滤器映射的顺序存在问题。不确定正确的顺序应该是什么？

Answer 1

尝试升级到插件的v1.2.5。它正确地命令过滤器映射元素（资源插件有一个问题，它也有严格的元素排序规则）。

有一件事看起来很奇怪，在'springSecurityFilterChain'过滤器映射之后有两个</filter-mapping>结束标记。此文件是否已编辑？
