如何在运行时创建多个指向不同Mysql数据库的Jdbctemplate bean？

@Configuration
public class DataSourceConfig {
    
    @Bean
    @ConfigurationProperties(prefix = "datasource.db1")
    public DataSource dataSource1() {
        return DataSourceBuilder.create().build();
    }
    
    @Bean
    @ConfigurationProperties(prefix = "datasource.db2")
    public DataSource dataSource2() {
        return DataSourceBuilder.create().build();
    }
    
    @Bean
    public JdbcTemplate jdbcTemplate1(@Qualifier("dataSource1") DataSource dataSource) {
        return new JdbcTemplate(dataSource);
    }
    
    @Bean
    public JdbcTemplate jdbcTemplate2(@Qualifier("dataSource2") DataSource dataSource) {
        return new JdbcTemplate(dataSource);
    }
}

# 数据源1配置
datasource.db1.url=jdbc:mysql://localhost:3306/db1
datasource.db1.username=username1
datasource.db1.password=password1

# 数据源2配置
datasource.db2.url=jdbc:mysql://localhost:3306/db2
datasource.db2.username=username2
datasource.db2.password=password2
