Question

尝试配置2个Hikari数据源，但只有一个被正确拾取，并且Hikari日志记录显示了配置。除了将其中一个设置为“主要”外，这些属性是相同的。

ActivityConfig：

@Configuration
public class ActivityConfig {

    @Bean
    @Primary
    @ConfigurationProperties(prefix = "activity.datasource")
    public DataSourceProperties activityDataSourceProperties() {
        return new DataSourceProperties();
    }

    @Bean(name = "activity-datasource")
    @Primary
    @ConfigurationProperties(prefix = "activity.datasource.hikari")
    public HikariDataSource activityDataSource() {
         System.out.println("properties url = " + activityDataSourceProperties().getUrl());
        HikariDataSource hikariDataSource = activityDataSourceProperties().initializeDataSourceBuilder().type(HikariDataSource.class)
                   .build();
        return hikariDataSource;
    }

SubscriptionConfig：

@Configuration
public class SubscriptionConfig {

    @Bean
    @ConfigurationProperties(prefix = "subscription.datasource")
    public DataSourceProperties subscriptionDataSourceProperties() {
        return new DataSourceProperties();
    }

    @Bean(name = "subscription-datasource")
    @ConfigurationProperties(prefix = "subscription.datasource.hikari")
    public HikariDataSource subscriptionDataSource() {
        System.out.println("properties url = " + subscriptionDataSourceProperties().getUrl());
        HikariDataSource hikariDataSource = subscriptionDataSourceProperties().initializeDataSourceBuilder().type(HikariDataSource.class)
                   .build();
        return hikariDataSource;

    }

application.properties：

#HikariCP  config
activity.datasource.url=jdbc:mysql://.../activity
activity.datasource.username=XXXX
activity.datasource.password=YYYY

#HikariCP  config
subscription.datasource.url=jdbc:mysql://.../subscription
subscription.datasource.username=XXXX
subscription.datasource.password=YYYY
subscription.datasource.driverClassName=com.mysql.cj.jdbc.Driver
subscription.datasource.hikari.connection-timeout=60000
subscription.datasource.hikari.maximum-pool-size=10
subscription.datasource.hikari.idle-timeout=300000
subscription.datasource.hikari.max-lifetime=1800000
subscription.datasource.hikari.minimum-idle=10
subscription.datasource.hikari.auto-commit=true
subscription.datasource.hikari.validation-timeout=15000
subscription.datasource.cachePrepStmts=true
subscription.datasource.prepStmtCacheSize=250
subscription.datasource.prepStmtCacheSqlLimit=2048
subscription.datasource.useServerPrepStmts=true
subscription.datasource.useLocalSessionState=true

subscription.datasource.cacheResultSetMetadata=true
subscription.datasource.cacheServerConfiguration=true
subscription.datasource.elideSetAutoCommits=true
subscription.datasource.maintainTimeStats=false
subscription.datasource.hikari.pool-name=SubscriptionPool

一切正常，但是Hikari仅记录“活动”数据源设置。而且在关闭时，没有提及“ SubscriptionPool ”。

仅来自Hikari的日志记录：

可能与之相关的是，我已指定 subscription 模式的Entity对象被报告为 activity 模式的一部分，并说该表不存在（ true！），当调用 find 方法时。

我是否配置错误，还是Hikari / Boot问题？

谢谢。

因此我发现我需要在每个配置类上添加 @EnableJpaRepositories 。这样，两个数据源都按预期配置。还必须在每个配置类的 entityManagerFactoryBean 方法中使用的每个 DataSource 参数中添加 @Qualifier ：

@Bean(name = "subscriptionEntityManager")
public LocalContainerEntityManagerFactoryBean entityManagerFactoryBean(EntityManagerFactoryBuilder builder,
                                                                       @Qualifier("subscription-datasource") DataSource dataSource) {
    return builder.dataSource(dataSource)
                   .packages("com.acornmedia.activeusers.subscription.repo")
                   .persistenceUnit("subscription")
                   .build();

Spring Boot 2 Hikari数据源配置错误？
