What I'm missing?

Answer 1

如果您已经使用具有 hikari 和数据源配置的 application.properties 文件，那么当您使用new HikariDataSource(this)时，它将覆盖您的 application.properties 值。

您可以手动创建 HikariDataSource 并从 application.properties 中删除：

@Bean(name = "dataSource")
public DataSource dataSource() {
    HikariDataSource hikariDataSource = new HikariDataSource();
    hikariDataSource.setMaximumPoolSize(5);
    hikariDataSource.setMaxLifetime(60000);
    hikariDataSource.setMinimumIdle(1);

    //.. some other configs
    return hikariDataSource;
}

或仅使用 application.properties 值。
