This kind of question is best asked on stackoverflow.com (use the spring-boot tag).

We don't currently offer any auto-configuration support for druid, but you should be able to configure directly as you would any other Spring Bean. Probably something like this:

@Bean
public DruidDataSource dataSource() {
    DruidDataSource ds = new DruidDataSource();
    ds.setUrl(...);
    ds.setUserName(...);
    ds.setPassword(...);
    // any other configuration
    return ds;
}
