你可以在Spring TaskExecutors中使用Future / Futuretask对象吗？(Can you use Future/Futuretask objects with Spring TaskExecutors?)

 是否有可能使用Java FutureTask和Spring TaskExecutor来获取Future对象？  
 我正在寻找一个实现Java ExecutorService接口的TaskExecutor，特别是submit（）方法。 透过Spring看看Javadocs并没有透露任何这样的类。 是否有一些备选方法可以通过Spring TaskExecutors处理未来的未知情况？  
 如果可能的话，你还可以加入一个例子吗？ 

Is it possible to use Java FutureTask with a Spring TaskExecutor to get a Future object?  
I'm looking for a TaskExecutor that implements the Java ExecutorService interface, in particular the submit() method. Looking through the Spring Javadocs doesn't reveal any classes like this. Is there some alternate method to handle futures through Spring TaskExecutors that I am unaware of? 
If it is possible, could you also include an example?

 KEY是一个保留字，所以你必须逃避它：  
@profiles = UserProfile.where("`key` = ? and id in (?)", 'Noc_Address', session[:profile_ids])
 
 或者让Rails为您处理：  
@profiles = UserProfile.where(key: 'Noc_Address', id: session[:profile_ids])

KEY is a reserved word so you have to escape it: 
@profiles = UserProfile.where("`key` = ? and id in (?)", 'Noc_Address', session[:profile_ids])
 
Or let Rails handle this for you: 
@profiles = UserProfile.where(key: 'Noc_Address', id: session[:profile_ids])

ActiveRecord的MySQL连接默认只能执行一个语句。要执行多个语句，需要在创建连接时将CLIENT_MULTI_STATEMENTS （65536）作为选项传递。代码可能如下所示： ConnectionAdapters::MysqlAdapter.new(mysql, logger, [host, username, password, database, port, socket, 65536], config) 您可以在mysql gem中找到ConnectionAdapters::My ...
