How to retrieve hashmap values in velocity template

问题

How to retrieve values from the following hashmap in velocity template? Please help..

LinkedHashMap<String, LinkedHashMap<Integer, Object>> hashmap = new LinkedHashMap<String, LinkedHashMap<Integer,Object>>();

回答1:

First, add the hashmap to your backing Java class (reference here).

context.put("myhashmap", hashmap);

Then you can reference anywhere in your Velocity template, e.g:

<span>$myhashmap.get("foo").get(1).toString()</span>

This worked for me:

$!myhashmap.get($!foo).toString();

Note: foo is a variable in my case.
