JSF1.2 和 Spring 安全性集成中的问题

Question

我正在JSF 1.2项目中实现spring安全性。这在JBoss 5.0.1中成功部署，但当我尝试访问应用程序的登录页面时，它给了我以下异常

Caused by: java.lang.IllegalArgumentException: FacesContext must not be null
at org.springframework.util.Assert.notNull(Assert.java:112)
at org.springframework.web.jsf.FacesContextUtils.getWebApplicationContext(FacesContextUtils.java:50)
at org.springframework.web.jsf.FacesContextUtils.getRequiredWebApplicationContext(FacesContextUtils.java:81)
at org.springframework.web.jsf.el.SpringBeanFacesELResolver.getWebApplicationContext(SpringBeanFacesELResolver.java:91)
at org.springframework.web.jsf.el.SpringBeanFacesELResolver.getBeanFactory(SpringBeanFacesELResolver.java:79)
at org.springframework.beans.factory.access.el.SpringBeanELResolver.getValue(SpringBeanELResolver.java:50)
at javax.el.CompositeELResolver.getValue(CompositeELResolver.java:54)

从这个跟踪中，我猜测springbean是如何在初始化之前使用faces上下文的。

以下是我的项目结构：

MyEar
|-- lib (contains all spring security jar files)  
|
|
|-- myWar
       |-- META-INF/MANIFEST.MF (entries for spring security jars)
       |
       |-- WEB-INF
               |-- applicationContext.xml 
               |-- lib (local jar files jsf,facelets etc)

这里有一件事很重要，那就是我希望我所有的spring securities jar都在ear的lib目录中，当我把所有的spring security jar都直接放在ear（earcontent）下而不是在lib中时，这个异常就不会发生。

请告诉我这是否是我的项目结构的问题？

更新：这是我的清单内容：

   Manifest-Version: 1.0
   Class-Path: lib/aopalliance-1.0.jar 
   lib/mysql-connector-java-5.1.7-bin.jar 
   lib/org.springframework.aop-3.0.5.RELEASE.jar 
   lib/org.springframework.asm-3.0.5.RELEASE.jar

   lib/spring-security-taglibs-3.0.5.RELEASE.jar 
   lib/spring-security-web-3.0.5.RELEASE.jar

以下是web.xml条目的一些部分：

        <!--  Delegating to a Spring-managed bean that implements the Filter interface -->
<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    <init-param>
        <param-name>targetBean</param-name>
        <param-value>filterChainProxy</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
    <dispatcher>FORWARD</dispatcher>
    <dispatcher>REQUEST</dispatcher>
</filter-mapping>
    <servlet>
      <servlet-name>Faces Servlet</servlet-name>
      <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
      <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
      <servlet-name>Faces Servlet</servlet-name>
      <url-pattern>*.jsf</url-pattern>
    </servlet-mapping>

Answer 1

FacesContext由FacesServlet创建。因此，当它是null时，就意味着您没有调用FacesServlet。您需要确保浏览器请求URL与您在web.xml中定义的FacesServlet的<url-pattern>相匹配。

如果是

<url-pattern>*.jsf</url-pattern>

然后，您需要确保将登录页面调用为

http://localhost:8080/myWar/login.jsf

因此不是作为

http://localhost:8080/myWar/login.xhtml
