HikariPool-1-springBoot 2多个数据源上需要dataSource或dataSourceClassName或jdbcUrl

Question

我正在尝试在springBoot 2中创建多个mysql数据源，但出现错误。

我已经在application.properties中配置了2个数据源，并通过引用分别创建了两个配置类 “ https://medium.com/@joeclever/using-multiple-datasources-with-spring-boot-and-spring-data-6430b00c02e7”

我的application.properties

#----- database 1 - customer -----#
spring.datasource.url=jdbc:mysql://localhost:3306/customers?useSSL=false
spring.datasource.username=root
spring.datasource.password=ram123
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5InnoDBDialect

#----- database 2 = forum ------#
spring.forum.datasource.url=jdbc:mysql://localhost:3306/forum?useSSL=false
spring.forum.datasource.username=root
spring.forum.datasource.password=ram123
spring.forum.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.forum.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5InnoDBDialect

My configuration Class


@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
        entityManagerFactoryRef = "customerEntityManagerFactory" ,
        transactionManagerRef = "customerTransactionManager",
        basePackages = { "io.habitate.repository.customer" }
)
public class CustomerDbConfig extends HikariConfig {

    @Primary
    @Bean(name = "customerDataSource")
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource dataSource() {
        return new HikariDataSource(this);
    }

    @Primary
    @Bean(name = "customerEntityManagerFactory")
    public LocalContainerEntityManagerFactoryBean
    customerEntityManagerFactory(
            EntityManagerFactoryBuilder builder,
            @Qualifier("customerDataSource") DataSource dataSource
    ) {
        return
                builder
                        .dataSource(dataSource)
                        .packages("io.habitate.model.customer")
                        .persistenceUnit("customers")
                        .build();
    }

    @Primary
    @Bean(name = "customerTransactionManager")
    public PlatformTransactionManager customerTransactionManager(
            @Qualifier("customerEntityManagerFactory") EntityManagerFactory
                    customerEntityManagerFactory
    ) {
        return new JpaTransactionManager(customerEntityManagerFactory);
    }

}
