java - FullTextHibernateSessionProxy 在类加载器中不可见

Question

我遇到了一个非常奇怪的错误，我无法理解。我正在运行 Seam 2.2.1.CR2 和 JBoss 4.3.0.GA。我的应用程序包含 3 个模块：

应用程序.xml

<display-name>CoolWebApp</display-name>
    <module id="EJB3">
        <ejb>EJB3.jar</ejb>
    </module>
    <module id="WEB">
        <web>
            <web-uri>WEB.war</web-uri>
            <context-root>/</context-root>
        </web>
    </module>
    <module>
        <ejb>jboss-seam-2.2.1.CR2.jar</ejb>
    </module>

以下 bean 已调度并且应该异步运行。它位于我的 EJB3 模块中：

package com.coolwebapp.indexing;

import org.apache.commons.lang.time.DateUtils;

public class IndexBean {

    @Logger
    private static Log log;

    /**

    }

                        .setParameter("nodeName", getNodeName())
                        .getResultList();

        Map<Long, Company> idToCompanyToIndexMap = new HashMap<Long, Company>();
        for (CompanyInNeedOfIndexing indexingTask : indexingTasks) {
            final Company company = indexingTask.getCompany();
            final long id = company.getId();
            if (!idToCompanyToIndexMap.containsKey(id))
                idToCompanyToIndexMap.put(id, company);
        }

        for (Company company : idToCompanyToIndexMap.values()) {
            log.info("Indexing " + company.getName());
            Events.instance().raiseEvent(CompanyTouched.EVENT_NAME, company, em);
            em.persist(new CompanyInNeedOfIndexing(company, getNodeName()));
        }
    }

    private String getNodeName() {
        return "N0";    // TODO get from -D param
    }

    @Startup(depends = {"applicationBean", "entityManager"})
    @Scope(ScopeType.APPLICATION)
    @Name("indexBeanKicker")
    public static class Kicker {

        private final long INTERVAL = 15;


        @In
        private IndexBean indexBean;

        @Create
        public void initBean() {
            log.info("Will check for indexing every " + INTERVAL + " minutes.");
            final Date firstRunIn30sec = new Date(30 * DateUtils.MILLIS_PER_SECOND + System.currentTimeMillis());
            indexBean.investigatePendingIndexings(
                    firstRunIn30sec, 
                    INTERVAL * DateUtils.MILLIS_PER_MINUTE);
        }
    }

}

当事件在 bean 拾取后引发时（也在 EJB3 模块中）：

package com.coolwebpp.search.util;

import javax.persistence.EntityManager;
import java.io.Serializable;

@Name("indexUtils")
@AutoCreate
@Scope(ScopeType.SESSION)
public class IndexUtils implements ArticleSaved, ReviewsUpdated, CompanyPublished, CompanyRemoved, SearchWordsUpdated, CompanyTouched, Serializable {

    public final static Log log = LogFactory.getLog(IndexUtils.class);

    public IndexUtils() {
    }

    public static FullTextEntityManager getFullTextEntityManager(EntityManager entityManager) {
        if (entityManager instanceof FullTextEntityManager)
            return (FullTextEntityManager) entityManager;
        else
            return Search.createFullTextEntityManager(entityManager);
    }

    private void reindexWithoutModifyingLastUpdated(Company company, EntityManager entityManager) {
        log.warn("--------------->>> Reindexing without updating lastModified: " + company.getName());
        getFullTextEntityManager(entityManager).index(company);
    }

    @Observer(CompanyTouched.EVENT_NAME)
    public void handleCompanyTouched(Company owningCompany, EntityManager entityManager) {
        reindexWithoutModifyingLastUpdated(owningCompany, entityManager);
    }

}

组件.xml

<persistence:managed-persistence-context name="entityManager"
                                           auto-create="true"
                                           entity-manager-factory="#{entityManagerFactory}"/>

  <persistence:entity-manager-factory name="entityManagerFactory"
                                      persistence-unit-name="theDatabase"/>

当我启动应用程序并且踢球者启动时，一切正常，直到

getFullTextEntityManager(entityManager).index(company);

然后抛出以下异常：

                                           auto-create="true" scope="APPLICATION"

  <persistence:entity-manager-factory name="entityManagerFactory"
                                      persistence-unit-name="theDatabase"/>

如果我删除调用 .index 保存实体的行（ em.persist(new CompanyInNeedOfIndexing(company, getNodeName())); ），但前提是我将范围设置为 APPLICATION。

你有什么想法为什么这不起作用？您有任何提示或需要更多信息吗？

简短的回答：

检查hibernatesearch.jar和quartz.jar是否在同一个库目录中，即都在default/lib（或<yourserver>/lib）中。

您可能quartz.jar来自quartz-ra.rar，这也应该有效。但是，如果您不需要这些quart-ra.rar设施，我建议您将其删除并quartz.jar放入default/lib.

长答案：

当您配置 Quartz 调度程序以管理 Seam 中的异步作业时，这些作业在启动时创建的石英线程池中运行。Java EE 中有很多依赖的逻辑，Thread.currentThread().getContextClassLoader()因此将池中的线程关联到正确的类加载器至关重要。

您应该避免重用quartz-ra.rarJBoss 默认安装的模块通常创建的线程池。

您在这里有两个选择。您可以删除quartz-ra.rar模块（如果不需要）并将quartz.jar 放在server/lib 中，或者为您的应用程序配置一个自定义quartz 配置，在应用程序类路径的根目录中创建一个seam.quartz.properties 文件。

在自定义中seam.quartz.properties，您定义了一个与默认不同的实例名称，以便您的应用程序继续使用她的私有线程池：

org.quartz.scheduler.instanceName = MyApplicationQuartzInstance
org.quartz.scheduler.instanceId = 1
org.quartz.scheduler.rmi.export = false
org.quartz.scheduler.rmi.proxy = false

org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 5

无论如何，创建 aseam.quartz.properties是个好主意，因为您可以调整其他一些石英参数，例如threadCount.
