[英]How to iterate over a map in mvel
I have a collection (map) which I want to use with the foreach orb tag. 我有一个要与foreach orb标记一起使用的集合(地图)。
How do i do this in mvel and is it also possible to get the current key? 我如何在Mvel中做到这一点,也有可能获得当前的钥匙?
Map<Integer, Integer> map = new HashMap<Integer, Integer>();
//java
for (Map.Entry<Integer, Integer> entry : map.entrySet())
{
System.out.println("Key = " + entry.getKey() + ", Value = " + entry.getValue());
}
//mvel
foreach (c : map.entrySet)
{
System.out.println("Key = " +c.key + ", Value = " +c.value);
}
