我在端口 8983 启动并运行 Solr 1.2 并使用 liferay 5.1.1 问题是如何配置 solr 以在 liferay JournalArticle 表中搜索我已经为 liferay 安装了 solr-web 插件，但它抛出了这个异常

顺便说一句，这是我的 solr-web solr-spring.xml

<beans>
    <bean id="indexSearcher" class="com.liferay.portal.search.solr.SolrIndexSearcherImpl">
     <property name="serverURL" value="http://localhost:8983/solr/select" />
    </bean>
    <bean id="indexWriter" class="com.liferay.portal.search.solr.SolrIndexWriterImpl">
     <property name="serverURL" value="http://localhost:8983/solr/update" />
    </bean>
    <bean id="searchEngine" class="com.liferay.portal.search.solr.SolrSearchEngineImpl">
  <property name="name" value="Solr" />
     <property name="searcher" ref="indexSearcher" />
     <property name="writer" ref="indexWriter" />
     <property name="indexReadOnly" value="false" />
    </bean>

 <bean id="searchEngineUtil" class="com.liferay.portal.search.solr.SolrSearchEngineUtil" lazy-init="false">
     <constructor-arg ref="searchEngine" />
     <constructor-arg ref="searchReaderMessageListener" />
     <constructor-arg ref="searchWriterMessageListener" />
    </bean>

在这种情况下 schema.xml 会是什么样子

看来您的应用服务器中必须有多个 portal-kernel.jar 文件。

此 jar 不能在至少包含应用服务器中的门户应用程序和插件的 ear 的上下文中复制，或者如果在 servlet 容器（如 tomcat）中运行，则不能在全局类路径中复制。

他 HttpUtils 类实际上被修改以适应需求，所以解决这个问题的方法是用我们修改的那个替换原来的内核类
