【问题描述】：
我正在使用 primefacess-5.1 和 apache shiro 1.2.2 以及 pax-shiro 0.1.0 覆盖。一切都在 Glassfish 4.0 上。我的问题是，当我在 web.xml 中评论下面的所有片段时
<filter>
<filter-name>ShiroFilter</filter-name>
<filter-class>org.apache.shiro.web.servlet.ShiroFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>ShiroFilter</filter-name>
<url-pattern> /*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
<dispatcher>INCLUDE</dispatcher>
<dispatcher>ERROR</dispatcher>
</filter-mapping>
ImageCropper 工作正常，但 shiro 不行。当我取消注释 shiro 上面的代码时工作正常，但是当我按下 p:imageCropper 中的按钮裁剪时，我得到错误 500，你可以在下面看到。

我的 JSF 表单如下
<h:body>
<h:form enctype="multipart/form-data">
<p:growl id="msgs" showDetail="true"/>
<h:panelGrid columns="2">
<p:imageCropper id="ic" value="#{cropperView.croppedImage}" image="http://rg-rgb-szkola:8080/dpsmvn-web/admin/images/tmp/portret_wup.jpg" initialCoords="225,75,300,125"/>
<p:graphicImage alt="po wykadrowaniu" id="cropped" rendered="#{cropperView.photocomlete==1?true:false}" library="images" name="twarze/pracownicy/#{cropperView.newImageName}.jpg" />
</h:panelGrid>
<p:commandButton value="Crop" action="#{cropperView.crop}" update="msgs ic cropped" icon="ui-icon-scissors" ajax="false"/>
<p:commandButton value="Zapisz" action="#{cropperView.saveImage()}" ajax="false" />
</h:form>
</h:body>
我的 shiro 配置如下
[main]
authc.successUrl = /witamy.xhtml
authc.loginUrl = /login.xhtml
roles.unauthorizedUrl = /accessdenied.xhtml
ssl.enabled = false
[urls]
/javax.faces.resource/** = anon
/ = anon
/images/tla/sloneczniki.jpg = anon
/images/tla/liscie-tlo.jpg = anon
/index.xhtml = anon
/login.xhtml = authc
/logout.xhtml = logout
/witamy.xhtml = authc
/pielegniarka/** = authc, roles[adminpielegniarka]
/admin/** = authc, roles[root]
/** = authc
对变量 ImageCropper imagecropper 负责的代码在下方，并且位于带有 @SessionScoped 的 CDI bean 内。我也可以说错误的原因是这个变量的 NULL 值。我想 shiro 不能识别这个变量的 mime 类型。我可以这么说，因为在我开始使用这个组件时，我收到了警告 WARNING: JSF1091
private CroppedImage croppedImage;
public CroppedImage getCroppedImage() {
return croppedImage;
}
public void setCroppedImage(CroppedImage croppedImage) {
this.croppedImage = croppedImage;
}
我的问题是如何将 apache shiro 与 p:imageCropper primefaces 组件同步？
