Will spring Boot datasource properties work if we configure datasource programmatically in Spring Boot - spring

Question

Will Spring Boot datasource properties work if we configure datasource programmatically?
The following properties worked only when I fetch DB configuration from application.properties. If I configure datasource programmatically the following properties are not working.
spring.datasource.tomcat.initial-size=10
spring.datasource.tomcat.max-active=10
spring.datasource.tomcat.max-idle=5
spring.datasource.tomcat.min-idle=5
I used the following code to configure datasource programmatically
#ConfigurationProperties(prefix = "spring.datasource")
#Bean
#Primary
public DataSource dataSource() {
return DataSourceBuilder.create().username(userName).password(password).url(url).driverClassName(driverName)
.build();
}
To make it work programmatically I used the following code snippet.But I'm not convinced. I feel it is not a cleaner solution. I have to read at least 20 properties from application.properties and add it to PoolProperties.
#ConfigurationProperties(prefix = "spring.datasource")
#Bean
#Primary
public DataSource dataSource() {
PoolProperties poolProperties = new PoolProperties();
poolProperties.setUrl(url);
poolProperties.setDriverClassName(driverName);
poolProperties.setUsername(userName);
poolProperties.setPassword(password);
poolProperties.setTestWhileIdle(false);
poolProperties.setTestOnBorrow(true);
poolProperties.setValidationQuery("SELECT 1 FROM DUAL");
poolProperties.setTestOnReturn(false);
poolProperties.setValidationInterval(30000);
poolProperties.setTimeBetweenEvictionRunsMillis(30000);
poolProperties.setInitialSize(10);
poolProperties.setMaxActive(10);
poolProperties.setMaxIdle(5);
poolProperties.setMinIdle(5);
poolProperties.setMaxWait(10000);
poolProperties.setRemoveAbandonedTimeout(60);
poolProperties.setMinEvictableIdleTimeMillis(30000);
poolProperties.setLogAbandoned(true);
poolProperties.setRemoveAbandoned(true);
DataSource datasource = new DataSource(); // import org.apache.tomcat.jdbc.pool.DataSource;
datasource.setPoolProperties(poolProperties);
return datasource;
}
It there way we can make the following default Spring Boot properties work?
spring.datasource.tomcat.initial-size=10
spring.datasource.tomcat.max-active=10
spring.datasource.tomcat.max-idle=5
spring.datasource.tomcat.min-idle=5

Answer 1

remember to give tomcat from properties for db in property files like this.
# Oracle DB - "foo"
spring.datasource.tomcat.url=jdbc:oracle:thin:#//db-server-foo:1521/FOO
spring.datasource.tomcat.username=fooadmin
spring.datasource.tomcat.password=foo123
spring.datasource.tomcat.initial-size=10
spring.datasource.tomcat.max-active=10
spring.datasource.tomcat.max-idle=5
spring.datasource.tomcat.min-idle=5
then configure datasource like this.
/**
* Auto-configured DataSource
*/
#ConfigurationProperties(prefix = "spring.datasource.tomcat")
#Bean
#Primary
public DataSource dataSource() {
return DataSourceBuilder.create().build();
}
