模糊查询：blog.csdn.net/weixin_4222…
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 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);
