Tomcat 在solr中声明多个实体时出错

tomcat solr

Tomcat 在solr中声明多个实体时出错,tomcat,solr,Tomcat,Solr,我刚刚开始学习solr。我已经安装了ApacheTomcat服务器和Solr3.5。我已成功配置solr，以便从oracle数据库中搜索一个实体的数据。当我在data-config.xml中添加两个实体并在solr schema.xml中添加字段时，我遇到了问题 <dataConfig> <dataSource name="JdbcDataSource" driver="oracle.jdbc.driver.OracleDriver"

solr无法读取第二个实体的任何字段。 有人能帮我解决这个问题吗。。？
请告诉我，在配置data-config.xml或schema.xml或这两个文件时，我犯了什么错误。

尽管从堆栈跟踪来看，您的一个计划文档在required plans\u applied字段中缺少值，但我认为您需要注意的第一件事是，数据不应该在Solr中进行规范化。它应该在进入索引之前被压平

因此，您不应该将这两个表作为单独的实体进行索引，而应该直接在data-config.xml中创建联接，而不是在这两个表之间创建查询，以便每个结果联接的表行都成为Solr文档

这样，当您想要获取关于单个项目的所有数据时，所有数据都将在单个文档中—这样的用例不需要连接

在Solr中，您应该接受冗余，而不是关系和约束

有意义吗？

如何连接这两个表以及如何配置schema.xml。。？我读过维基，但不懂。所以，如果你能用一个小例子来解释我，那将是很有帮助的。。谢谢。你想搜索什么？仅项目和计划或多个表？关键是你需要将数据展平。考虑一下从项目和计划的联接查询中选择*的结果。结果是一个新的临时表，其中包含两个表中的所有列。这就是您需要对其内容要搜索的所有表执行的操作。然后，大表中的一行变成了一个Solr文档。关键是你要回答你想搜索哪些表？我明白你的意思了…实际上还有一个表，但首先我想用上面提到的表来配置它。。将只有一个输入用于搜索，关于该输入，我必须显示表中的所有值。。比如，如果我输入一个id值，然后从PLANS表中找到匹配项..我的搜索应该只从该表中获取所有细节。。。有可能这样做吗。。？如果你能给我一个加入solr的例子，我会很有帮助…我知道如何在sql中加入表，但不能理解solr中的语法…我不确定从你的评论中你是否真正理解了这一点。下面是从rdb展平数据的示例：
