非存储字段搜索,适应灵活的搜索场景

1、非存储字段搜索

1.1 描述

通常根据本模型之外的信息作为搜索条件时,通常会把 这些字段放在代理模型上。这类场景我们称之为 非存储字段搜索

1.2 场景一

非存储字段为基本的String。
1.代码定义:非存储字段为基本的包装数据类型

    @Field(displayName = "确认密码", store = NullableBoolEnum.FALSE)
    private String confirmPassword;

2.设计器拖拽:列表中需要有退拽这个字段,字段是否隐藏的逻辑自身业务是否需要决定。

3.页面通过非存储字段为基本的包装数据类型进行搜索时。会拼在 queryWrapper 的属性queryData中,queryData为Map,key为字段名,value为搜索值。

4.后台逻辑处理代码示例:

        Map<String, Object> queryData = queryWrapper.getQueryData();
        if (null != queryData) {
            Object productIdObj = queryData.get(PRODUCT_ID);
            if (Objects.nonNull(productIdObj)) {
                String productId = productIdObj.toString();
                queryWrapper.lambda().eq(MesProduceOrderProxy::getProductId, productId);
            }
        }

1.3 场景二

非存储字段为非存储对象。

  1. 定义 为非存储的
    @Field(displayName = "款", store = NullableBoolEnum.FALSE)
    @Field.many2one
    @Field.Relation(store = false)
    private MesProduct product;

2.页面在搜索栏拖拽非存储字段作为搜索条件

3.后台逻辑处理代码示例:

      try {
            if (null != queryData && !queryData.isEmpty()) {
                List<Long> detailId = null;
                BasicSupplier supplier = JsonUtils.parseMap2Object((Map<String, Object>) queryData.get(supplierField), BasicSupplier.class);
                MesProduct product = JsonUtils.parseMap2Object((Map<String, Object>) queryData.get(productField), MesProduct.class);
                MesMaterial material = JsonUtils.parseMap2Object((Map<String, Object>) queryData.get(materialField), MesMaterial.class);
                if (supplier != null) {
                    detailId = bomService.queryBomDetailIdBySupplierId(supplier.getId());
                    if (CollectionUtils.isEmpty(detailId)) {
                        detailId.add(-1L);
                    }
                }

                if (product != null) {
                    List<Long> produceOrderId = produceOrderService.queryProductOrderIdByProductIds(product.getId());
                    if (CollectionUtils.isNotEmpty(produceOrderId)) {
                        queryWrapper.lambda().in(MesProduceBomSizes::getProduceOrderId, produceOrderId);
                    }
                }

                if (material != null) {
                    //找出两个bom列表的并集
                    List<Long> materBomDetailId = bomService.queryBomDetailIdByMaterialId(material.getId());
                    if (CollectionUtils.isNotEmpty(detailId)) {
                        detailId = detailId.stream().filter(materBomDetailId::contains).collect(Collectors.toList());
                    } else {
                        detailId = new ArrayList<>();
                        if (CollectionUtils.isEmpty(materBomDetailId)) {
                            detailId.add(-1L);
                        } else {
                            detailId.addAll(materBomDetailId);
                        }
                    }
                }
                if (CollectionUtils.isNotEmpty(detailId)) {
                    queryWrapper.lambda().in(MesProduceBomSizes::getProductBomId, detailId);
                }
            }
        } catch (Exception e) {
            log.error("queryData处理异常", e);
        }

注意: 如果这样定义

    @Field(displayName = "款",store = NullableBoolEnum.FALSE)
    @Field.Relation(relationFields = "produceId", referenceFields = "id",store = false)
    @Field.many2one
    private MesProduct product;

    @Field(displayName = "款Id",store = NullableBoolEnum.FALSE)
    private Long produceId;

搜索时 produceId 选择product 搜索是 produceId 会被拼接在QueryWrapper 的Rsql中

Rsql解析类

pro.shushi.pamirs.framework.gateways.rsql.RSQLHelper

Rsql参考代码

/**
     * Rsql解析 将属性字段值从QueryWrapper中originRsql属性值的Rsql解出来
     * 将原有条件替换成 ’1‘==’1‘
     *
     * @param queryWrapper 查询Wrapper
     * @param fields       需要解析出来的属性字段列表
     * @param valeMap      属性对应值的Map
     * @return 返回生产单Id列表
     */

    public static QueryWrapper convertWrapper(QueryWrapper queryWrapper, List<String> fields, Map<String, Object> valeMap) {
        if (StringUtils.isNotBlank(queryWrapper.getOriginRsql())) {
            String rsql = RSQLHelper.toTargetString(RSQLHelper.parse(queryWrapper.getModel(), queryWrapper.getOriginRsql()), new RSQLNodeConnector() {
                @Override
                public String comparisonConnector(RSQLNodeInfo nodeInfo) {
                    //判断字段为unStore,则进行替换
                    String field = nodeInfo.getField();
                    if (fields.contains(field)) {
                        valeMap.put(field, nodeInfo.getArguments().get(0));
                        RSQLNodeInfo newNode = new RSQLNodeInfo(nodeInfo.getType());
                        //设置查询字段为name
                        newNode.setField("1");
                        newNode.setOperator(RsqlSearchOperation.EQUAL.getOperator());
                        newNode.setArguments(Collections.singletonList("1"));
                        return super.comparisonConnector(newNode);
                    }
                    return super.comparisonConnector(nodeInfo);
                }
            });
            queryWrapper = Pops.f(Pops.query().from(queryWrapper.getModel())).get();
            //把RSQL转换成SQL
            String sql = RsqlParseHelper.parseRsql2Sql(queryWrapper.getModel(), rsql);
            if (StringUtils.isNotBlank(sql)) {
                queryWrapper.apply(sql);
            }
            return queryWrapper;
        }
        return queryWrapper;

  • 后端:如何自定义表达式实现特殊需求?扩展内置函数表达式

    平台提供了很多的表达式,如果这些表达式不满足场景?那我们应该如何新增表达式去满足项目的需求?目前平台支持的表达式内置函数,参考 1. 扩展表达式的场景 注解@Validation的rule字段支持配置表达式校验如果需要判断入参List类型字段中的某一个参数进行NULL校验,发现平台的内置函数不支持该场景的配置,这里就可以通过平台的机制,对内置函数进行扩展。 常见的一些代码场景,如下: package pro.shushi.pamirs.demo.core.action; ……引用类 @Model.model(PetShopProxy.MODEL_MODEL) @Component public class PetShopProxyAction extends DataStatusBehavior<PetShopProxy> { @Override protected PetShopProxy fetchData(PetShopProxy data) { return data.queryById(); } @Validation(ruleWithTips = { @Validation.Rule(value = "!IS_BLANK(data.code)", error = "编码为必填项"), @Validation.Rule(value = "LEN(data.name) < 128", error = "名称过长,不能超过128位"), }) @Action(displayName = "启用") @Action.Advanced(invisible="!(activeRecord.code !== undefined && !IS_BLANK(activeRecord.code))") public PetShopProxy dataStatusEnable(PetShopProxy data){ data = super.dataStatusEnable(data); data.updateById(); return data; } ……其他代码 } 2. 新建一个自定义表达式的函数 校验入参如果是个集合对象的情况下,单个对象的某个字段如果为空,返回false的函数。 例子:新建一个CustomCollectionFunctions类 package xxx.xxx.xxx; import org.apache.commons.collections4.CollectionUtils; import org.springframework.stereotype.Component; import pro.shushi.pamirs.meta.annotation.Fun; import pro.shushi.pamirs.meta.annotation.Function; import pro.shushi.pamirs.meta.common.constants.NamespaceConstants; import pro.shushi.pamirs.meta.util.FieldUtils; import java.util.List; import static pro.shushi.pamirs.meta.enmu.FunctionCategoryEnum.COLLECTION; import static pro.shushi.pamirs.meta.enmu.FunctionLanguageEnum.JAVA; import static pro.shushi.pamirs.meta.enmu.FunctionOpenEnum.LOCAL; import static pro.shushi.pamirs.meta.enmu.FunctionSceneEnum.EXPRESSION; /** * 自定义内置函数 */ @Fun(NamespaceConstants.expression) @Component public class CustomCollectionFunctions { /** * LIST_FIELD_NULL 就是我们自定义的表达式,不能与已经存在的表达式重复!!! * * @param list * @param field * @return */ @Function.Advanced( displayName = "校验集成的参数是否为null", language = JAVA, builtin = true, category = COLLECTION ) @Function.fun("LIST_FIELD_NULL") @Function(name = "LIST_FIELD_NULL", scene = {EXPRESSION}, openLevel = LOCAL, summary = "函数示例: LIST_FIELD_NULL(list,field),函数说明: 传入一个对象集合,校验集合的字段是否为空" ) public Boolean listFieldNull(List list, String field) { if (null == list) { return false; } if (CollectionUtils.isEmpty(list)) { return false; } for (Object data : list) { Object value =…
