Konfigurowanie Grails 3.1.0 z MySQL

Oto moja

build.gradle:

dependencies {
    runtime 'mysql:mysql-connector-java:5.1.20'

}

Teraz application.yml:

dataSources:
    dataSource:
        pooled: true
        jmxExport: true
        driverClassName: com.mysql.jdbc.Driver
        dialect: org.hibernate.dialect.MySQL5InnoDBDialect
        username: username
        password: opendoor_policy
    nextdbsource:
        pooled: true
        jmxExport: true
        driverClassName: com.mysql.jdbc.Driver
        dialect: org.hibernate.dialect.MySQL5InnoDBDialect
        username: username
        password: opendoor_policy
        url: jdbc:mysql://localhost:3306/nextdbsource?autoReconnect=true&useUnicode=yes&characterEncoding=UTF-8
        dbCreate: update

environments:
    development:
        dataSources:
            dataSource:

    test:

                properties:
                    jmxEnabled: true
                    initialSize: 5
                    maxActive: 50

                    timeBetweenEvictionRunsMillis: 5000
                    minEvictableIdleTimeMillis: 60000
                    validationQuery: SELECT 1
                    validationQueryTimeout: 3
                    validationInterval: 15000
                    testOnBorrow: true
                    testWhileIdle: true
                    testOnReturn: false
                    jdbcInterceptors: ConnectionState
                    defaultTransactionIsolation: 2 # TRANSACTION_READ_COMMITTED
