使用Jira中的Groovy从服务器拉系统日志

Question

I am new to Groovy in Jira, and I am trying to pull syslogs off a certain database. I am wondering if anyone can put me to the right direction. I am using the script console to implement this.

I am guessing it will be on the local host. I am given these to access the database server :

-Database server with Port Number
-Database name
-Password
-Application Database User
-Syslog Servers

Are there any tutorials I can use to be able to connect to the database server

Thank you very much,

Groovy provides the Sql class to simplify connecting to JDBC data sources. Here's an example.

import groovy.sql.Sql

def jdbc = 'jdbc:h2:mem:'
def db = Sql.newInstance(jdbc, 'org.h2.Driver')

def foos = db.rows('select foo from bar')
...
db.close() // Done with connection

The driver and JDBC connection string depends on the DBMS you're connecting to (MySQL, PostgreSQL, etc).

PostgreSQL example

Here's how to connect to PostgreSQL. The code below uses Groovy's Grape to download dependencies.

Note: @GrabConfig is required to load the org.postgresql.Driver class in a way that allows jdbc to find it.

@Grab('org.postgresql:postgresql:9.3-1101-jdbc41')
@GrabConfig(systemClassLoader=true)

import groovy.sql.Sql

def host = '192.168.1.1'
def port = 5432
def dbname = 'foo'
def user = 'xxx'
def password = 'yyy'
def jdbc = "jdbc:postgresql://${host}:${port}/${dbname}"
def db = Sql.newInstance(jdbc, user, password, 'org.postgresql.Driver')
