项目里的web.xml不报错，out文件夹里的web.xml报错 感觉不是jar包没导入成功问题。 

首先我简单阐述下问题： 1，本人用spring集成shiro 2，但是必须要写listen监听，如果不写 <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> 则运行到登录验证页面就报错 org.apache.shiro.UnavailableSecurityManagerException: No SecurityManager accessible to the calling code, either bound to the org.apache.shiro.util.ThreadContext or as a vm static singleton.

如题： 在web.xml中配置了两个或者多个的filter，他们的执行顺序是什么，是依次执行（也就是按顺序执行，配置在前的先执行，配置在后的后执行），还是怎么回事： 如下代码： 这是公司一个项目的架构，我在研究的时候发现的，始终搞不明白： web.xml的部分配置文件： <!--配置的filter--> <filter> <filter-name>struts2Filter</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <!-- UrlRewrite filter --> <filter> <filter-name>urlRewriteFilter</filter-name> <filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class> </filter> <!--配置的filtermapping--> <filter-mapping> <filter-name>struts2Filter</filter-name> <url-pattern>*.action</url-pattern> <dispatcher>REQUEST</dispatcher> <dispatcher>FORWARD</dispatcher> </filter-mapping> <filter-mapping> <filter-name>urlRewriteFilter</filter-name> <url-pattern>/*</url-pattern> <dispatcher>REQUEST</dispatcher> <dispatcher>FORWARD</dispatcher> </filter-mapping> 就像这两个，到底谁先执行，谁后执行？

``` <context-param> <param-name>contextConfigLocation</param-name> <param-value> <!-- classpath:db.properties --> <!-- classpath:main-config.xml --> <!-- classpath:config/fweb-archetype-mvc.xml --> classpath:config/fweb-shiro-mvc.xml </param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <filter> <filter-name>shiroFilter</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> <!-- 设置true由servlet容器控制filter的生命周期 --> <init-param> <param-name>targetFilterLifecycle</param-name> <param-value>true</param-value> </init-param> <!-- 设置spring容器filter的bean id，如果不设置则找与filter-name一致的bean--> <init-param> <param-name>targetBeanName</param-name> <param-value>shiroFilter</param-value> </init-param> </filter> <filter-mapping> <filter-name>shiroFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> ``` 把上面的配置全部通过java方式配置要如何写

``` <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/resource/spring/applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> ``` 加了上面的listener之后页面就404了，但是springmvc的前端控制器可以正常加载 这是项目结构 

 在idea中部署好tomcat，并产生war包，在运行的时候tomcat自带的界面显示完全没问题，但是自己的页面遇到异常，web.xml文件解析绝对路径的情况。 希望大神们看看是怎么回事

分为两个项目，shiro-client 与 shiro-server, server 依赖client ， shiro的配置文件applicationShiro.xml 在client中，applicationShiro.xml 中有一些bean 比如自定义realm 等，报错 就是报这些错，找不到自定义的realm，filter等，这些自定义 realm 是在client中的，但就是找不到，我看tomcat中发布目录页是有这个client这个jar包 的，但就是找不到，会是哪里错了呢？
