使用最新版本的 Solr 5.0 获取异常。降级到较早的版本（4.10.4），但该版本有其自身的问题（请参阅 Exception No.2）。

SolrConfig 类

public class SolrEmbeddedConfig {
    @Autowired
    private Environment environment;

     @Bean
        public EmbeddedSolrServerFactoryBean solrServerFactoryBean() {

            EmbeddedSolrServerFactoryBean factory = new EmbeddedSolrServerFactoryBean();
            factory.setSolrHome(environment.getRequiredProperty("embeded.solr.home"));

            return factory;
        }

    @Bean
    public SolrTemplate solrTemplate() throws Exception {
        return new SolrTemplate(solrServerFactoryBean().getObject());
    }

}

例外 1：使用最新版本的 Solr 5.0 引发

Solr/SolrJ 5 版本比简单的SolrClient. 因此 Spring-Data-Solr 目前还不兼容较新的客户端库。但是，github上已经有一个DATASOLR-232的问题分支。

出于某种原因，4.10.x 版本EmbeddedSolrServer有时会在关闭时保留写锁。这会导致无法启动服务器的问题。也许有<unlockOnStartup>true</unlockOnStartup>帮助。

除了 solrj 5.x 中的 solrClient 更改之外，它们还更改了类继承层次结构，这使得 spring-data-solr 当前版本 1.4.1 与 solrj 5.x 不兼容

HttpSolrServerFactory (spring-data-solr) 期望 SolrServer (solrj) 实现类 (HttpSolrServer) 在 4.10.x 版本中可用，但从 5.x 版本的 solrj HttpSolrServer 不扩展 SolrServer 但属于 HttpSolrClient 的不同继承层次结构导致问题.

需要等待支持 5.x 版本 solrj 的 spring-data-solr 的最新开发。检查spring-data-solr github
