Iterating through hashmap in freemarker

I have a hashmap as shown below

HashMap<String, String> testStatus = new HashMap<String, String>();
Map root = new HashMap();

public void fmTest() {

testStatus.put("one","1");
testStatus.put("two","2");
testStatus.put("three","3");
root.put("status", testStatus);
testStatus.clear();
}

My FTL:

<#list status?keys as key> 
${key} = ${status[key]}
</#list>

The above code is just an example. My question is, if I loop the hashmap of testStatus to have different values ​​in each loop and clean up at the end of the loop ... how can I create a freemarker to display the testhatus key value pair from each loop.

If I haven't cleared the hashmap of testStatus, I get the cumulative result. But if I cleared the hashmap of testStatus the freemarker doesn't display anything.

HashMap<String, String> testStatus = new HashMap<String, String>();


put this declaration in the fmTest method, then when every time you call the method a new Map will be placed in the root so they won't accumulate ...
