title: Jackson - Serialize boolean to 1/0 instead of true/false
body: <p>I have REST resource that receives JSON object which is a map from user ID to some boolean that indicate if this user had errors.  </p>
  
  <p>Since I'm expecting a large number of users, I would like to shrink the size of this JSON by using 1/0 instead of true/false.  </p>
  
  <p>I tried and found that during desalinization Jackson will convert 1/0 to true/false successfully, but is there a way to tell Jackson (maybe using annotation?) to serialize this boolean field to 1/0 instead of true/false?</p>
