Solr search engine - Configure the data source by mysql

First, prepare the database
data table structure

CREATE TABLE `app` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`app_name` varchar(255) NOT NULL DEFAULT '',
`score` decimal(10,5) NOT NULL DEFAULT '0.00000',
`downLoadNum` int(10) NOT NULL DEFAULT '0',
`top` int(10) NOT NULL DEFAULT '0',
`type` int(10) NOT NULL DEFAULT '1',
`update_date` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8mb4;

<!-- Request Handlers

Incoming queries will be dispatched to a specific handler by name
based on the path specified in the request.

If a Request Handler is declared with startup="lazy", then it will
not be initialized until the first request that uses it.
