 查
 
 Query  query = new Query();
        query.addCriteria(Criteria.where("uid").is(uid));
        query.addCriteria(Criteria.where("mykey").is(DateUtils.getDate()));
        EmailCount mgt = mongoTemplate.findOne(query, EmailCount.class);
        
全文索引
TextCriteria criteria = TextCriteria.forDefaultLanguage()
  .matchingAny("coffee", "cake");

Query query = TextQuery.queryText(criteria)
  .sortByScore()
  .with(new PageRequest(0, 5));

List<CookingRecipe> recipes = template.find(query, CookingRecipe);

增改

 Query query = new Query();
        String mykey = DateUtils.getDate();
        query.addCriteria(Criteria.where("uid").is(uid));
        query.addCriteria(Criteria.where("mykey").is(mykey));
        Update update = new Update().set("mykey", mykey);
        mongoTemplate.upsert(query, update, EmailCount.class);
