    While i different options , i found a way to do this and is as below.

     

    ${=org.apache.commons.lang.RandomStringUtils.randomNumeric(5)}

     

    Number 5 represents the length for the number.

For example, to use a number between 1, and 1000 thousand, use the following as value for rest request itself. See if the below helps.
"${= new Random.nextInt(1, 1000)}"

      Sorry, there was typo.
      Change from:
      ${= new Random.nextInt(1, 1000)}

      to

      ${= new Random().nextInt(1, 1000)}

        Hi,

         

        "id": ${= new Random().nextInt(1,1000)},

         

        The above format when used throws the below error .

         

        "id": No signature of method: java.util.Random.nextInt() is applicable for argument types: (java.lang.Integer, java.lang.Integer) values: [1, 1000]
        Possible solutions: nextInt(), nextInt(int), nextLong(), nextFloat(), notify()
