Springboot mongodb

 package com.ruoyi.common.mongodb;

import org.springframework.data.mongodb.core.mapping.Document;

@Document(collection = "emailcount")
public class EmailCount {
    private String mykey;
    private String uid;

    public String getMykey() {
        return mykey;
    }

    public void setMykey(String mykey) {
        this.mykey = mykey;
    }

    public String getUid() {
        return uid;
    }

    public void setUid(String uid) {
        this.uid = uid;
    }
}

 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);
