   正确的方式是通过collectionFormat声明格式  
   spring的处理是有歧义的，需要是一个数组，那么传递来了`q=a,b,c`，实际应该是一个数组有三个元素，还是一个数组有一个元素呢？  
   只有声明collectionFormat 为csv，才是明确表示一个数组有三个元素
   如果collectionFormat 为multi，这是表示一个数组有一个元素，此时想要表示一个数组有三个元素，应该传递`q=a&q=b&q=c`
   
   扩展机制参考：org.apache.servicecomb.common.rest.codec.query.QueryCodecCsv
