我开始将一个 wep 应用程序从 Tomcat 6 更新到当前版本的 Tomcat (7-27)。当我使用以下错误消息启动服务器时出现问题：

com.qnamic.railopt.web.security.portlet.PortletSecurityFilter 类确实实现了接口 javax.portlet.filter.PortletFilter：

import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.security.Principal;

import javax.portlet.ActionRequest;
import javax.portlet.ActionResponse;
import javax.portlet.EventRequest;
import javax.portlet.EventResponse;
import javax.portlet.PortletException;
import javax.portlet.PortletMode;

import javax.portlet.PortletSession;
import javax.portlet.RenderRequest;
import javax.portlet.RenderResponse;
import javax.portlet.ResourceRequest;

import javax.portlet.filter.ActionFilter;
import javax.portlet.filter.EventFilter;
import javax.portlet.filter.FilterChain;
import javax.portlet.filter.FilterConfig;
import javax.portlet.filter.RenderFilter;
import javax.portlet.filter.ResourceFilter;

import org.apache.log4j.Logger;
import org.springframework.security.access.AccessDeniedException;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;

public class PortletSecurityFilter implements ActionFilter, EventFilter, RenderFilter, ResourceFilter {

ActionFilter 确实实现了 javax.portlet.filter.PortletFilter

依赖的罐子是：

一些依赖项具有“提供”的范围，并且不包括在战争中（只要tomcat不使用它们）！

我的 portlet.xml 的一部分

<filter>
<filter-name>PortletSecurityFilter</filter-name>
        <filter-class>com.qnamic.railopt.web.security.portlet.PortletSecurityFilter</filter- class>
    <lifecycle>ACTION_PHASE</lifecycle>
    <lifecycle>EVENT_PHASE</lifecycle>
    <lifecycle>RENDER_PHASE</lifecycle>
    <lifecycle>RESOURCE_PHASE</lifecycle>
    <init-param>
        <name>message</name>
        <value>Security Filter</value>
    </init-param>
</filter>

<filter-mapping>
    <filter-name>PortletSecurityFilter</filter-name>
    <portlet-name>*</portlet-name>
</filter-mapping>

其他依赖项位于父项目中：

  • pc-api-2.2.0-GA.jar
  • pc-controller-2.2.0-GA.jar
  • pc-portlet-2.2.0-GA.jar
  • pc-mc-2.2.0-GA.jar
  • wci-wci-2.1.1-GA.jar
  • wci-tomcat7-2.1.1-GA.jar

当我在 org.gatein.pc.portlet.impl.jsr168.ClassInstanceLifeCycle.create(...) 中调试代码时，它停在第二行

Class clazz = classLoader.loadClass(className);
if (expectedClass.isAssignableFrom(clazz)) {
    Class<? extends T> castedClass = clazz.asSubclass(expectedClass);
    Constructor<? extends T> ctor = castedClass.getConstructor();
    instance = ctor.newInstance();
}
else  {
    String msg = "Cannot create " + type + " with class " + className + " because it does not   implement the expected interface " + expectedClass.getName();
    throw new PortletInitializationException(msg);
}

我的建议首先是类加载器存在问题，但它不应该是，因为第一行正确加载了类 PortletSecurityFilter。正如预期的那样，预期的类是 javax.portlet.filter.PortletFilter。为什么这个类是不可分配的？

我感谢任何帮助！

我必须承认，我不知道您用来解决此问题的 GateIn 的确切版本是什么，但无论如何我可以通过简单地保留（故意）portlet-api-2.0 来使用 GateIn-3.2.0.Final-tomcat7 重现此问题.jar 在我的 war 文件的 WEB-INF/lib 目录中。然后我可以得到类似的东西：

我可以通过简单地从我的 webapp 的 WEB-INF/lib 中删除 portlet-api-2.0.jar 来修复它（或者在提供的 maven 中定义这个依赖项）。发生这种情况仅仅是因为 jar 文件已经在 tomcat/lib 中，所以 Portlet Container 引用了从 Tomcat 的公共 ClassLoader 加载的类 javax.portlet.filter.PortletFilter，而您的 Filter 实现了类 javax.portlet.filter。 PortletFilter 已从您的 webapp 的 ClassLoader 加载（来自 WEB-INF/lib），即使这 2 个类的 FQN 相等，它们也不被视为相同的类，这就是为什么 expectedClass.isAssignableFrom(clazz)返回假。
