How to Connect to Oracle Database in Grails 3 Project with Intellij IDEA?

Question

I'm trying to run a Grails 3 app with Intellij IDEA,but I don't know how to connect to oracle database, and where should I put the oracle jdbc driver? Here is my code in application.yml --- hibernate: cache: queries: false use_second_level_cache: true use_query_cache: false region.factory_class: 'org.hibernate.cache.ehcache.EhCacheRegionFactory'

dataSource:
    pooled: true
    jmxExport: true
    driverClassName: oracle.jdbc.driver.OracleDriver
    username: "wy"
    password: "19901110"

    development:
        dataSource:
            dbCreate: update
            url: jdbc:oracle:thin:@//localhost:1521/DBW

and I put the jdbc driver into here: jdbc driver

Hope someone can solve my problem

Thank You Very Much!!!

Answer 1

To allow your application to use Oracle as a database, you have to add the jar file of Oracle jdbc driver into the Lib folder, inside your project directory. This can be done by simply copying the driver file into the Lib folder. After that, simply modify your Application.yml file.

假设您使用的是JDK，请将您的Oracle jar放在[JAVA_HOME] / jre / lib / ext中
