我正在尝试使用Spring Data Solr从后端Solr服务器查询内容，该服务器具有以下schema.xml（为了简单起见，仅显示字段），这是从Nutch {{1}复制的}。这意味着我使用Nutch爬网，然后将段传递给Solr：
schema.xml现在，查看Spring Data Solr的文档，例如：
http://docs.spring.io/spring-data/solr/docs/1.4.x/reference/html/#reference
他们使用的方法和字段似乎与我的架构中的字段不匹配。例如，在他们的文档中：

或
public interface ProductRepository extends Repository<Product, String> {
List<Product> findByNameAndPopularity(String name, Integer popularity);
}
看着我的田地，我没有一个叫“名字”，“人气”或“可用”的字段。我错过了什么？我应该更改我的架构吗？我应该从文档中更改存储库吗？
这最后一个问题似乎很愚蠢，但是因为我看到的使用Spring Data Solr的例子只创建了一个public interface ProductRepository extends SolrRepository<Product, String> {
@Query("inStock:?0")
List<Product> findByAvailable(Boolean available);
}
模型（我知道它是一个例子，但是示例通常反映默认情况！）及其相应的Solr存储库和它们通常包含诸如“名称”，“流行度”，“作者”之类的字段，我不确定这些字段实际代表什么或映射到哪些字段。
答案 0 :(得分：0)
You need to define a Java object which mirrors your SOLR doc, using the @Field annotation.
