SpringBoot Cloud Foundry override Database Pool Size - Communications link failure - mysql

Question

After researching I have found that a default pool size of 4 is created by Spring Boot when deploying to the cloud. I am deploying to Cloud Foundry, using Spring Boot 1.3.7, and connecting to a MySQL service. I would like to increase the default pool size. I am following the steps outlined in the this blog, but I am getting the error below. I do not have an issue connecting to the DB when using autoconfiguration with the service, so the DB is accessible. Any ideas or suggestions would be greatly appreciated!!!!!

Answer 1

I am all set. For some reason spring boot was picking up the database connection URL from my local application.yml file instead of using the Cloud Foundry Service in the manifest.yml of my deployment. When I removed the connection information from the local application.yml it now works.

Answer 2

I can't say exactly what happened, but a couple things you can do here.
If you want to use Spring Cloud Connectors, like in your example above, you need to set a PoolConfig. See the last two examples here or the following snippet.
#Bean
public DataSource dataSource() {
PoolConfig poolConfig = new PoolConfig(5, 30, 3000);
DataSourceConfig dbConfig = new DataSourceConfig(poolConfig, null);
return connectionFactory().dataSource("my-own-personal-sql", dbConfig);
}
You can use Spring profiles. By default, the Java buildpack is going to enable the "cloud" profile for your application, so you can put anything you only want active when running on Cloud Foundry in that profile. You can then create a "local" profile, or something like that, where you can put your apps configuration for when it's running locally on your PC (you do need to enable this profile, it won't happen automatically).
In this way the contents of the two profiles won't overlap, but at the same time you don't have to manually swap settings based on the environment where your app is running.
For what it's worth, Spring Boot's --debug option and/or raising log levels for org.springframework.cloud to DEBUG would help to debug issues like this. You should see more details.
