First, the project mainly consists of the following three steps:
    1. Configure Database Information
    2. Writing a crawler script
    3. Configuring the Jenkins Timer task
    4. View Collection Results
Ii. detailed procedures 1. Configure Database Information

Build a table statement with some of these fields as an example:

CREATE TABLE ' stockmarket ' (' Date ' varchar () Not NULL DEFAULT"'COMMENT'Time', ' stockcode ' varchar () Not NULL DEFAULT"'COMMENT'Stock Code', ' stockname ' varchar ((+) DEFAULT NULL COMMENT'Stock name', ' Close ' Decimal (19,2) DEFAULT NULL COMMENT'Price', ' High ' decimal (19,2) DEFAULT NULL COMMENT'Highest', ' Low ' decimal (19,2) DEFAULT NULL COMMENT'Minimum', ' Amplituderatio ' Decimal (19,2) DEFAULT NULL COMMENT'amplitude', ' Turnoverratio ' Decimal (19,2) DEFAULT NULL COMMENT'rate of change of hand', ' Preclose ' Decimal (19,2) DEFAULT NULL COMMENT'prev. closed', ' Open ' decimal (19,2) DEFAULT NULL COMMENT'Open Price', PRIMARY KEY (' Date ', ' Stockcode ')) ENGINE=innodb DEFAULT Charset=utf8;

Configure JSON data to a. json file for reading configuration information for database connections

"Stockmarket":{      "Host":"localhost",      "Port": 3326,      "User":"Root",      "Password":"Password",      "Database":"Stockmarket",      "CharSet":"UTF8"    }

2. Scripting

The Python library involved

Import re,pymysql,json,time,requests

3. Configure Jenkins

Remote SSH configuration, configuring timed tasks (Tip: Recommended night to collect (or close time), as trading time, stock data in the dynamic change)

jenkins> System Configuration >ssh remote hosts ( I am installed virtual machine, CENTOS7 version, has been configured to Jdk,python3,mysql,tomcat and other common software services )
