i have found from the document, and seems that spring-boot only support tomcat-jdbc,HikariCP and DBCP connection pool, if i want to use druid(https://github.com/alibaba/druid/wiki/FAQ) in my project with spring-boot, may i know how to do?

This kind of question is best asked on *.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;

}
