• mongoTemplate CURD 和模糊查询(转)


    此文基于Spring的MongoTemplate,介绍MongoDB比较基础常用的增删改查操作。涵盖了从集合创建、索引创建和CRUD操作到更高级的功能(如Map-Reduce和聚合)等等。不多说,直接上代码。

    模糊查询:https://blog.csdn.net/weixin_42227975/article/details/80533678

    1、精确查询用“is”
    
                Criteria criteria=new Criteria("namespaceName");
                criteria.is(namespaceName);
                Query query = new Query(criteria);
                return mongoTemplate.find(query,StorageBO.class,StorageConstant.STORAGE_COLLECTION_NAME);
    2、模糊查询用“regex”
    
                Criteria criteria=new Criteria("storageName");
                criteria.regex(storageName);
                Query query = new Query(criteria);
                return mongoTemplate.find(query,StorageBO.class,StorageConstant.STORAGE_COLLECTION_NAME);
    3、模糊查询示例2
    
    //完全匹配
    Pattern pattern = Pattern.compile("^hzb$", Pattern.CASE_INSENSITIVE);
    //右匹配
    Pattern pattern = Pattern.compile("^.*hzb$", Pattern.CASE_INSENSITIVE);
    //左匹配
    Pattern pattern = Pattern.compile("^hzb.*$", Pattern.CASE_INSENSITIVE);
    //模糊匹配
    Pattern pattern = Pattern.compile("^.*hzb.*$", Pattern.CASE_INSENSITIVE);
    Query query = Query.query(Criteria.where(fieldName).regex(pattern));  
            List<StorageBO> storages = mongoTemplate.find(query, StorageBO.class, collectionName);
            return storages;
    
     4、按createTime降序排序
    
    以下红色部分是排序设置
    
    
                Criteria criteria=new Criteria("namespaceName");
                criteria.is(namespaceName);
                criteria.and("tenantName").is(tenantName);
                Query query = new Query(criteria);
                query.with(new Sort(Sort.Direction.DESC,   "createTime"));
                return mongoTemplate.find(query,StorageBO.class,StorageConstant.STORAGE_COLLECTION_NAME);

            en = Collation.of("en")
                    // 排序规则强度定义表示字符之间差异的比较级别。
                    // 根据所选的强度,可以配置各种选项(区分大小写、大小写排序等)。
                    .strength(Collation.ComparisonLevel.secondary().includeCase())

                    .alternate(Collation.Alternate.shifted().punct())
                    // 指定带有变音符号的字符串是否从字符串的后面排序,例如使用英语字典排序。
                    .forwardDiacriticSort()
                    // 指定是否检查文本是否需要规范化以及是否执行规范化。
                    .normalizationEnabled();
            // 排序可用于创建集合和索引。如果您创建了一个指定排序规则的集合,则排序规则将应用于索引创建和查询
