SOLR Import XML file

< c13>1 Overview

Most applications store data in relational databases, XML files. Searching for such data is a very common application. The so-called Dataimporthandler provides a configurable way to import data to SOLR, which can be imported all at once or incrementally.

Ability to read data in a relational database.

The ability to generate multi-column, multi-table data from a database in the SOLR document in a configurable way

Ability to update SOLR through SOLR documentation

Provides the ability to import all data through a configuration file

Ability to configure time for full import and incremental import

Let's read the XML file and make the index configurable.

The ability to integrate other data sources (for example: ftp,scp,etc) or other forms of documentation (JSON,CSV) into the project as plug-ins.

2.3 Importing an XML file

2.3.3 Import

Enter the SOLR directory, such as: G:\solr\example\exampledocs directory;

Java-dtype=text/xml-durl=http://localhost:8983/solr/solr_xml/update  -jar Post.jar   book.xml

After the import is complete, you can query the data in the interface queries, such as:
