如何修复 LockObtainFailedException：锁获取超时？

Question

当我从 Gradle 任务运行它们时，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：锁获取超时：NativeFSLock@/opt/solr/example/solr/collection1/data/index/write.lock

当我直接在 Intellij 中运行集成测试时，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 并且它没有效果。

 @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();
}

这是日志。一切似乎都在正确关闭。

这是我的环境信息：

• Linux 薄荷 17
• 索尔 4.9.0
• Solr 测试框架 4.9.0
• 甲骨文 Java 1.7
• Spring Data Solr 1.2.2.RELEASE
• IntelliJ 13.1.4
• 摇篮 1.12
• 测试是在 Spock 中开发的

任何帮助将不胜感激。谢谢！

好的，所以我能够通过更改来解决问题

<unlockOnStartup>true</unlockOnStartup>

在 solrconfig.xml 文件中。
