spring boot mongodb 实现多条件查询并分页

public Page<ResolveRule> findAllResolveRules(int size, int page, HttpServletRequest request){
        String assetType = request.getParameter(\"asset_type\");
        String assetCompany = request.getParameter(\"asset_company\");
        String assetModel = request.getParameter(\"asset_model\");
        String enable = request.getParameter(\"enable\");

        Query query = new Query();
        Criteria criteria = new Criteria();

        if (StringUtils.isNotBlank(assetType)){
            criteria.and(\"asset_type\").is(assetType);
        }

        if (StringUtils.isNotBlank(assetCompany)){
            criteria.and(\"asset_company\").is(assetCompany);
        }

        if (StringUtils.isNotBlank(assetModel)){
            criteria.and(\"asset_model\").is(assetModel);
        }

        if (StringUtils.isNotBlank(enable)){
            boolean b = BooleanUtils.toBoolean(enable);
            criteria.and(\"is_enable\").is(b);
        }

        query.addCriteria(criteria);

        Pageable pageable = new PageRequest(size,page);
        List<ResolveRule> resolveRules = mongoTemplate.find(query.with(pageable), ResolveRule.class);
        long total = mongoTemplate.count(query, ResolveRule.class);

        return new PageImpl(resolveRules, pageable, total);
    }
