Alexey Plotnik commented on IGNITE-13029:
-----------------------------------------
Default way to enable repositories is to assing @EnableIgniteRepositories to
Spring Configuration, basically adding a single line of code.
When using Spring Boot we are forced to use {{spring-boot-autoconfigure-ext}}
artifact, its purpose to initialize Ignite instance. Important: this module
knows nothing about spring-data at all, it's just an ignite core specific
auto-configurer. I guess it's not correct to add @EnableIgniteRepositories to
org.apache.ignite.springframework.boot.autoconfigure.IgniteAutoConfiguration
Another way is to create standalone artifact, i.e.
{{spring-boot-starter-data-ignite}}, an autoconfig class will look like this:
{code}
@EnableIgniteRepositories
public class IgniteDataAutoConfiguration {
}
{code}
The issue here is that by default spring data will be looking for Repository
classes in packages described in {{basePackages}} parameter of annotation, so
it expect something like:
{code}
@EnableIgniteRepositories(basePackages = "com.gridgain.investigate")
public class IgniteDataAutoConfiguration {
}
{code}
If base package is not defined, the one where internal auto-configuration class
of {{spring-boot-autoconfigure-ext}} located will be used
(org.apache.ignite.springframework.boot.data.autoconfigure) which is wrong. To
avoid that behaviour we must somehown parametrize basePackages value and
provide correct packages from user application.
It looks like there are too many steps to just move @EnableIgniteRepositories
from regular spring configuration to auto-configuration.
Could anyone talk to me about motivation of this improvement?
