我在Windows Server 2012上安装了Solr 5.0.0。我想将表中的所有数据加载到solr引擎中。
我的data-config.xml如下所示:
<?xml version="1.0" encoding="UTF-8" ?>
<!--# define data source -->
<dataConfig>
<dataSource type="JdbcDataSource"
driver="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/database"
user="root"
password="root"/>
<document>
<entity name="my_table"
pk="id"
query="SELECT ID, LASTNAME FROM my_table limit 2">
<field column="ID" name="id" type="string" indexed="true" stored="true" required="true" />
<field column="LASTNAME" name="lastname" type="string" indexed="true" stored="true"/>
</entity>
</document>
</dataConfig>
当我选择数据导入时,我得到了一个答案:
Indexing completed. Added/Updated: 2 documents. Deleted 0 documents
Requests: 1, Fetched: 2, Skipped: 0, Processed: 2
原始调试响应:
{
"responseHeader": {
"status": 0,
"QTime": 280
},
"initArgs": [
"defaults",
[
"config",
"data-config.xml"
]
],
"command": "full-import",
"mode": "debug",
"documents": [
{
"id": [
1983
],
"_version_": [
1497798459776827400
]
},
{
"id": [
1984
],
"_version_": [
1497798459776827400
]
}
],
"verbose-output": [
"entity:my_table",
[
"document#1",
[
"query",
"SELECT ID,LASTNAME FROM my_table limit 2",
"time-taken",
"0:0:0.8",
null,
"----------- row #1-------------",
"LASTNAME",

],
"document#2",
[

"LASTNAME",

],
"document#3",

]
],

"Optimized": "2015-04-07 15:05:22",
"Total Documents Processed": "2",
"Time taken": "0:0:0.270"
}
}
最后,当我查询Solr 时
http://localhost:8983/solr/test/query?q=*:*
我有一个答案:
{
"responseHeader":{
"status":0,
"QTime":0,
"params":{
"q":"*:*"}},
"response":{"numFound":2,"start":0,"docs":[
{
"id":"1983",
"_version_":1497798459776827392},
{
"id":"1984",
"_version_":1497798459776827393}]
}}
我也想看看姓氏栏。为什么我不能?
日志中的警告实际上才是真正的问题。
如果您查看solrconfig.xml文件,您将看到一个部分:
<schemaFactory class="ManagedIndexSchemaFactory">
<bool name="mutable">true</bool>
<str name="managedSchemaResourceName">managed-schema</str>
</schemaFactory>
这意味着您的schema.xml文件将被忽略。相反,将使用同一文件夹中的文件管理架构。
有几种方法可以解决这个问题。您可以注释掉托管模式部分,并将其替换为
<schemaFactory class="ClassicIndexSchemaFactory"/>
或者另一种方法是删除托管模式文件。SOLR将在重新启动时读取schema.xml文件,并生成一个新的托管模式。如果这样做有效,那么您应该在文件底部看到您的字段。
