Bonjour tous le monde,

J'ai un petit souci a implementer deux datasource dans mon code. J'ai 4 interfaces qui heritent chacune de CrudRepository.
Je souhaiterai que deux des interfaces utilisent la database A et les deux autres la database B.
Malgre une longue recherche sur internet je n'ai pas trouve d'exemple qui conviennent a mon code.

j'ai essaye de creer deux fichier DBConfig comme ceci :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

import org.springframework.boot.autoconfigure.jdbc.DataSourceBuilder;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.scheduling.annotation.EnableScheduling;
 
@Configuration
@EnableScheduling
@EnableJpaRepositories(basePackages = "{com.so.ic.services.currencies.dal, com.so.ic.services.ccpairs.dal}")
public class MasterDBConfig {
 
	@Bean(name = "datasource")
	@Primary
	@ConfigurationProperties(prefix = "spring.datasource.master")
	public DataSource dataSource() {
		return DataSourceBuilder.create().build();
	}
}

	@Bean(name = "master")
	@ConfigurationProperties(prefix = "spring.datasource")
	public DataSource masterDataSource() {
		return DataSourceBuilder.create().build();
	}
}

Voici un exemple d'une des interfaces qui herite de CrudRepository (les trois autres sont identiques) :

Code :

package com.so.ic.services.platform.dal;
 
import org.springframework.data.repository.CrudRepository;
 
import com.so.ic.services.platform.dal.entities.PlatformEntity;
 
public interface PlatformDbInterface extends CrudRepository<PlatformEntity, Long> {
 
}

Code :

Application.properties :

spring.datasource.password=mypasswordic
spring.datasource.schema=ic
spring.datasource.max-active=20
spring.datasource.max-idle=10
spring.datasource.max-wait=10000
spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.testOnBorrow=true
spring.datasource.validationQuery=SELECT 1
 
spring.datasource.master.url=jdbc:mysql://myUrl
spring.datasource.master.username=myusername
spring.datasource.master.password=mypassword
spring.datasource.master.schema=ic
spring.datasource.master.max-active=20
spring.datasource.master.max-idle=10
spring.datasource.master.max-wait=10000
spring.datasource.master.driverClassName=com.mysql.jdbc.Driver
spring.datasource.master.testOnBorrow=true
spring.datasource.master.validationQuery=SELECT 1

Mais lorsque je lance mon appli, les autowired de ses interfaces ne fonctionnent plus :

J'ai compris que l'utilisation de @EnableJpaRepositories etait une des solutions mais j'ai vu qu'en plus de l'attribute basePackages il y avait des attributs en rapport avec EntityManager dont je n'ai aucune idee de ce que c'est.

Est ce quelqu'un pourrait me donner une direction ?

merci
