Application for parsing of catalogs and products of the site http://old.relefopt.ru

This online store displays prices only to authorized users. The content of specific products is formed by a separate ajax request.

Requirements

• JDK 1.8

• Maven 3

• PostgreSQL 9.x

Install and setup

1. Setup JAVA_HOME (https://confluence.atlassian.com/doc/setting-the-java_home-variable-in-windows-8895.html)

2. Setup MAVEN_HOME (https://www.mkyong.com/maven/how-to-install-maven-in-windows/ or https://www.tutorialspoint.com/maven/maven_environment_setup.htm)

3. Create PostgreSQL database

All properties for connecting to the database are stored in the database.properties file:

db.url=jdbc:postgresql://localhost:5432/_oldrelefopt , where

localhost - address of the database

5432 - port of the database

_oldrelefopt - name of the database

db.username=postgres , where

postgres - login for connecting to the database

db.password=postgres , where

postgres - password for connecting to the database

4. Setup authorization credentials:

site.user.login=_yourlogin , where _yourlogin is your login for authorization on the site

site.user.password=_yourpassword , where _yourpassword is your password for authorization on the site

Run

1. To build jar file, execute next command:

mvn clean package

Result: relef-parser-{version}.jar file will be created in the /target directory.

2. To run jar file, execute next command:

java -jar relef-parser-{version}.jar

The application prints help if you run it without arguments.

Run examples

1. Start fast full parsing:

java -jar relef-parser-{version}.jar -pf 0

2. Export products:

java -jar relef-parser-{version}.jar -ep

Creates a file products_{datetime}.xlsx in the directory /exports

3. Download images of all products:

java -jar relef-parser-{version}.jar -dpi

Creates many images in directory /downloads

Post install (optional)

1. If you need to analyze percent of matching names with products from MySklad system then you need to create PostgreSQL indexes:

1.1. https://stackoverflow.com/a/16552593/8035065

CREATE EXTENSION pg_trgm;

1.2. https://www.postgresql.org/docs/9.3/static/pgtrgm.html

CREATE INDEX trgm_idx_t_product_name ON t_product USING gist (name gist_trgm_ops);
