从类加载器中看不到FullTextHibernateSessionProxy [英] FullTextHibernateSessionProxy is not visible from class loader
本文介绍了从类加载器中看不到FullTextHibernateSessionProxy的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我遇到了一个非常奇怪的错误，我无法解决问题.我正在运行Seam 2.2.1.CR2和JBoss4.3.0.GA.我的应用程序包含3个模块:
application.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已安排好，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;
import org.jboss.seam.Component;
import org.jboss.seam.ScopeType;
import org.jboss.seam.annotations.AutoCreate;

import org.jboss.seam.annotations.Transactional;
import org.jboss.seam.annotations.async.Asynchronous;
import org.jboss.seam.annotations.async.Expiration;
import org.jboss.seam.annotations.async.IntervalDuration;
import org.jboss.seam.core.Events;
import org.jboss.seam.log.Log;
import com.coolwebapp.events.CompanyTouched;
import com.coolwebapp.model.Company;
import com.coolwebapp.model.CompanyInNeedOfIndexing;
import javax.persistence.EntityManager;
import java.util.Date;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
/**

*/
@Name("indexBean")
@AutoCreate
public class IndexBean {
@Logger
private static Log log;
/**
* @return Will fetch an applicationBean
*/
private EntityManager entityManager() {
return (EntityManager) Component.getInstance("entityManager", true);
}
@SuppressWarnings({"unchecked"})
@Transactional
@Asynchronous
public void investigatePendingIndexings(@Expiration Date when, @IntervalDuration Long interval) {
log.info("IndexBean.investigatePendingIndexings()");
final EntityManager em = entityManager();
List<CompanyInNeedOfIndexing> indexingTasks =
em.createQuery(
"from CompanyInNeedOfIndexing C where C.hasBeenIndexedOnNode not like :nodeName")
.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);
}
}
}
在引发事件之后，以下bean将其拾取(同样在EJB3模块中):
package com.coolwebpp.search.util;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.apache.lucene.document.Document;
import org.hibernate.annotations.common.reflection.java.JavaReflectionManager;
import org.hibernate.search.engine.DocumentBuilder;
import org.hibernate.search.jpa.FullTextEntityManager;
import org.hibernate.search.jpa.Search;
import org.hibernate.search.store.NotShardedStrategy;
import org.jboss.seam.ScopeType;
import org.jboss.seam.annotations.AutoCreate;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Observer;
import org.jboss.seam.annotations.Scope;
import com.coolwebapp.events.CompanyTouched;
import com.coolwebapp.model.Company;
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);
}
}
components.xml
<persistence:managed-persistence-context name="entityManager"
auto-create="true"
entity-manager-factory="#{entityManagerFactory}"/>
<persistence:entity-manager-factory name="entityManagerFactory"
persistence-unit-name="theDatabase"/>
当我启动应用程序时，踢脚踢的一切正常，直到
getFullTextEntityManager(entityManager).index(company);
然后引发以下异常:

全文本管理器来自hibernatesearch-3.0.1.GA.
如果我删除了调用.index的行，则保存实体的工作(em.persist(new CompanyInNeedOfIndexing(company，getNodeName()));)，但前提是我将范围设置为APPLICATION.
您有什么想法为什么这行不通?您有任何提示吗?还是需要更多信息?
解决方案
简短答案:
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.
您可能有来自quartz-ra.rar的quartz.jar，这也应该起作用.但是，如果您不需要quart-ra.rar工具，建议您将其删除并将quartz.jar放入default/lib.
详细答案:
当您配置Quartz调度程序来管理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中有很多逻辑取决于Thread.currentThread().getContextClassLoader()，因此将池中的线程与正确的类加载器相关联至关重要.
您应该避免的是重用默认情况下在JBoss中安装的quartz-ra.rar模块通常创建的线程池.
您在这里有两个选择.要么删除quartz-ra.rar模块(如果不需要)，然后将quartz.jar放置在服务器/lib中，要么为应用程序配置自定义的石英配置，在应用程序类路径的根目录中创建seam.quartz.properties文件.
在自定义seam.quartz.properties中，您定义了一个实例名称，该实例名称与默认名称不同，以便您的应用程序继续使用其私有线程池:
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，创建一个seam.quartz.properties都是一个好主意，因为您可以调整其他一些石英参数，例如threadCount.
I have run into a very strange error that I can´t wrap my head around. I´m running Seam 2.2.1.CR2 and JBoss 4.3.0.GA. My application consist of 3 modules:

The fulltextentitymanager comes from hibernatesearch-3.0.1.GA.
If I remove the line calling .index saving the entity works( em.persist(new CompanyInNeedOfIndexing(company, getNodeName())); ), but only if I have the scope set to APPLICATION.
Do you have any ideas why this doesn't work? Do you any tips or do you need more information?
解决方案
Short answer:
Check if hibernatesearch.jar and quartz.jar are in the same library directory, that is both in default/lib (or <yourserver>/lib).
You may have quartz.jar coming from quartz-ra.rar, that should also works. However, if you don't need the quart-ra.rar facilities I suggest you to remove it and put quartz.jar in default/lib.
Long answer:
When you configure the Quartz dispatcher to manage asynchronous jobs in Seam, that jobs run in the quartz threads pool that is created at startup time. There is much logic in Java EE that depends on Thread.currentThread().getContextClassLoader() so it's critical for the threads in the pool to be associated to the correct classloader.
What you should avoid is reusing the thread pool that is commonly created by the quartz-ra.rar module installed by default in JBoss.
You have two options here. Either you remove quartz-ra.rar module (if not needed) and put quartz.jar in server/lib, or you configure a custom quartz configuration for your application creating a seam.quartz.properties file in the root of the application classpath.
In the custom seam.quartz.properties you define an instance name different by the default one, so that your application keeps using her private threads pool:
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
Creating a seam.quartz.properties is a good idea anyway, because you can tune some other quartz parameters like threadCount.
这篇关于从类加载器中看不到FullTextHibernateSessionProxy的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
