Question

当我从Gradle任务运行它时，我的集成测试失败了。

org.springframework.data.solr.UncategorizedSolrException: **SolrCore 'collection1' is not available due to init failure: Error opening new searcher; nested exception is org.apache.solr.common.SolrException: SolrCore 'collection1' is not available due to init failure: Error opening new searcher**
at org.springframework.data.solr.core.SolrTemplate.execute(SolrTemplate.java:122)
at org.springframework.data.solr.core.SolrTemplate.saveDocuments(SolrTemplate.java:206)
at org.springframework.data.solr.core.SolrTemplate.saveDocuments(SolrTemplate.java:201)

org.apache.lucene.store.LockObtainFailedException：Lock获取超时：NativeFSLock@/opt/solr/example/solr/collection1/data/index/write.lock

当我在Intellij中直接运行集成测试时，测试成功运行。这是我对嵌入式服务器的bean定义。我添加了destroyMethod，它没有任何效果。

 @Bean(destroyMethod = "shutdown")
public SolrServer solrServer(org.apache.commons.configuration.Configuration configuration)  {

    EmbeddedSolrServerFactory factory;
    try {
        factory = new EmbeddedSolrServerFactory(configuration.getString("solr.home"));
    } catch (ParserConfigurationException | IOException | SAXException e) {
        String errorMsg = "Encountered an exception while initializing the SolrServer bean.";
        log.error(errorMsg, e);
        throw new OrdersClientRuntimeException(errorMsg, e);
    }
    return factory.getSolrServer();
}

以下是日志。一切似乎都在正常关闭。

这是我的环境信息：

Linux Mint 17
Solr 4.9.0
Solr Test Framework 4.9.0
Oracle Java 1.7
Spring Data Solr 1.2.2.RELEASE
IntelliJ 13.1.4
Gradle 1.12
测试是在Spock中开发的。

非常感谢任何帮助。谢谢！

我的测试遇到了同样的问题但是unlockOnStartup标志对我没用。我最终改变了锁定类型（并将unlockOnStartup注释掉了）：

<lockType>${solr.lock.type:single}</lockType>
<!--<unlockOnStartup>true</unlockOnStartup>-->

关于默认锁定类型（本机）的说明让我觉得我不会在测试运行之间关闭服务器，但我还没有找到它：（

         native = NativeFSLockFactory - uses OS native file locking.
                  Do not use when multiple solr webapps in the same
                  JVM are attempting to share a single index.

刚刚遇到类似问题并修复了它。

我在单元测试中使用EmbeddedSolrServer并在运行时动态创建新内核。

创建CoreContainer时，请务必在测试后调用shutdown（）。

还要确保在测试后关闭所有SolrCore个实例。

调用coreContainer.create(CoreDescriptor, name, ...)会打开一个必须手动关闭的SolrCore。

通过传递coreName创建EmbeddedSolrServer时，SolrCore未打开！每个请求/操作都由EmbeddedSolrServer处理打开和关闭。

好的，我可以通过更改

解决问题

<unlockOnStartup>true</unlockOnStartup>

在solrconfig.xml文件中。
