How to integrate mysql or mongodb to grails 3.2.10 - mysql

Question

I'm about start with a web application project and I am trying to integrate Mysql into Grails 3. All of the online tutorials show us to change the DataSource file which does not currently (there is Application.yml).
I tried changing the Application.yml as given in the official documentation, but it gives me a big error. Its a new project and has no other changes to it. I've used grails 2.4 previously, it was really easy with that and now I'm thinking of changing back.
Change:
dataSource :
pooled : true
dbCreate : "update"
url : "jdbc:mysql://localhost:3306/my_database"
driverClassName : "com.mysql.jdbc.Driver"
dialect : org.hibernate.dialect.MySQL5InnoDBDialect
username : "username"
password : "password"
properties :
jmxEnabled : true
initialSize : 5
maxActive : 50
minIdle : 5
maxIdle : 25
maxWait : 10000
maxAge : 10 * 60000
timeBetweenEvictionRunsMillis : 5000
minEvictableIdleTimeMillis : 60000
validationQuery : "SELECT 1"
validationQueryTimeout : 3
validationInterval : 15000
testOnBorrow : true
testWhileIdle : true
testOnReturn : false
jdbcInterceptors : "ConnectionState;StatementCache(max=200)"
defaultTransactionIsolation :
java.sql.Connection.TRANSACTION_READ_COMMITTED
the error I get:
/usr/lib/jvm/java-8-oracle/bin/java -XX:+TieredCompilation -

Answer 1

The problem is with the way you're trying to set the maxAge value on your data source:
Failed to convert property value of type 'java.lang.String' to
required type 'long' for property 'maxAge'; nested exception is
java.lang.NumberFormatException: For input string: "10*60000"
Try just setting a concrete value rather than a calculation.

Answer 2

If you are not very comfortable with YML standard then simply create a new file with name application.groovy, place it inside the conf directory and add the datasource block in that groovy file. Don't forget to remove the data source block from application.yml file.
