使用 HikariCP 的属性配置 Spring 云连接器的 PoolConfig 和 ConnectionConfig

Question

我正在尝试使用 HikariCP 的 配置 Spring Cloud Connector 的 PoolConfig 和 ConnectionConfig属性。

这是我的 Sring Cloud Connector 数据源配置：

@Configuration
@Profile({Profiles.CLOUD, Profiles.DEV})
public class DataSourceConfiguration extends AbstractCloudConfig {

    @Bean
    @Qualifier("application_database")
    @Primary
    public DataSource applicationDatasource() {
        PoolConfig poolConfig = new PoolConfig(5, 11, 3000);//Notice 11 for maxPoolSize
        ConnectionConfig connConfig = new ConnectionConfig("poolName=dummy;characterEncoding=UTF-8");
        DataSourceConfig dbConfig = new DataSourceConfig(poolConfig, connConfig);
        return connectionFactory().dataSource("application_database", dbConfig);
    }
}

这是 HikariCP 报告：

可以注意到 HikariCP 没有考虑 PoolConfig 中指定的 11 的 maxPoolSize：Hikari 的 maximumPoolSize 保持在：10。 .. 有人可以帮忙吗？

我看到你已经 filed a GitHub issue 了。您似乎发现了连接器上的错误。我会在问题中进一步评论。
