in javascript I can write the follow code: 

response = {
    status: 1,
    data: {
        key : 2
    }
}
var result = `status is ${response.status}, data key is ${response.data.key}`
console.log(result);

the output is 

status is 1, data key is 2

Is there any libs provide the way to do it in java, providing the following function? 

String xxxFunction(Map map, String template)

please note the usage of ${response.data.key}, map in map

You can make use of String.format

String template = "status is %s, data key is %s"
String result = String.format(template, status, key);

    While this may answer the question, you should expand your answer by providing some explaining text and documentation for further reading. – hellow Aug 16 '18 at 11:10

    Not the same thing... – theMayer Jan 09 '20 at 16:45
  • @theMayer - what do you mean ? – MasterJoe Aug 04 '20 at 21:38

    @MasterJoe, string.format is not the same thing - not even close to the same thing - as a template literal. In fact, it’s what you’re trying to avoid with a template literal. So the correct answer is “Java doesn’t offer this.” Game, set, and match to C# – theMayer Aug 06 '20 at 11:58

You can try StrSubstitutor from Apache common text

 Map valuesMap = HashMap();
 valuesMap.put("animal", "quick brown fox");
 valuesMap.put("target", "lazy dog");
 String templateString = "The ${animal} jumps over the ${target}. ${undefined.number:-1234567890}.";
 StrSubstitutor sub = new StrSubstitutor(valuesMap);
 String resolvedString = sub.replace(templateString);
