@Configuration

@EnableJpaRepositories(
        entityManagerFactoryRef = "defaultEntityManagerFactory",
        transactionManagerRef = "defaultTransactionManager",
        basePackages = {
                "com.domain.visualisation.shared.repository"
        }
)
public class DefaultDbConfig {

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

    @Primary
    @Bean(name = "defaultEntityManagerFactory")
    public LocalContainerEntityManagerFactoryBean
    entityManagerFactory(
            EntityManagerFactoryBuilder builder,
            @Qualifier("defaultDataSource") DataSource dataSource
    ) {
        return builder
                .dataSource(dataSource)
                .packages("com.domain.visualisation.shared.entities")
                .persistenceUnit("default")
                .build();
    }

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

为什么它们没有被应用？

Answer 1

如果有多个数据源，并且由于您使用的是DataSourceBuilder，以下工作如下。

spring.datasource.maximum-pool-size=20
trwbi.datasource.maximum-pool-size=20

另外，在您的情况下，我建议关闭自动配置：

@SpringBootApplication(scanBasePackages = {...},
        exclude = {DataSourceAutoConfiguration.class} )
@EnableSwagger2
public class Application {
....

如果不使用生成器，而是使用自动配置，则使用

spring.datasource.hikari.minimumIdle=1
spring.datasource.hikari.maximum-pool-size=3
