How to iterate map in a template using play framework 1.4.2

I have got a map where the key is a object but the value is a list object. I am using play framework 1.4.2 (using groovy template).

This is the map: 

Map<Object, List<Object>> map = new HashMap<>();

How can iterating through the map values in a template?

Solution

  • You can use entrySet() to iterate over the map just like you would do in java (see this SO answer), then create a variable in a groovy script to get the value and key : 

    #{list items:map.entrySet(), as:'set' }
  ∗{print the key}*
  ${set.key}
  *{iterate over value list }∗
  #{list items: set.value, as:'itemValue'}
    ${itemValue}
  #{/list}

#{/list}
