如何计算速度模板中列表的大小？

Question

How to calculate list size in velocity template? I am using velocity 1.4.

List<String> list = new ArrayList<String>();

Answer 1

I assume that you mean "how do you call java methods in in the velocity template" because the method you are looking for is on the "List" javadoc, already mentioned.

I believe this article would be helpful:

How to access/get the size of an array/collection in velocity templates?

To save you a read, you should just be able to input this:

${myArrayList.size()}

Answer 2

list.size（）“以列表大小值数据类型'Integer'返回”
