假设您正在使用gem // intercept all incoming routes and log it
interceptFrom().process(new Processor() {
@Override
public void process(Exchange exchange) throws Exception {
System.out.println("Triggered");
}
});
,您最好按照其官方文档中的建议尝试将数据库适配器更改为activerecord-postgis-adapter

您遇到的问题是ActiveRecord中不存在 point 方法。
实例化表的新列。 type参数通常是迁移本机类型之一,它是以下之一:: primary_key,:string,:text,:integer,:float,:decimal,:datetime,:time,:date,:binary,:布尔值。
希望这有帮助
