Elasticsearch version 7.0.1
PostgreSQL 10.9
openJDK 11
I want to get data using full text search of Elasticsearch from PostgreSQL database,how can I do it , anyone know about Elasticsearch? have any ideas for that?
You can't do this directly;
You can try using logStash to inject your PostgreSQL data to Elastisearch and then ask Elasticsaearch directly.
Here you can find full solution; https://medium.com/#erangadulshan.14/pushing-relational-data-to-elasticsearch-using-logstash-jdbc-input-plugin-48af81ed1000

I have set up a JPA Database connection for my Eclipse Java project to a PostGreSQL database. I was wondering if there was a way to create a class for one of the tables without doing everything by hand.
Yes,you can use hibernate reverse engineering. Pretty much with some simple set up, it will generate java pojo class for you.
