Jooq/CRUD, Paging/Sorting

This chapter will focus on Jooq advanced search operation, it could be used in different pagination list table, you can refer current tutorial to check more details about how to write advanced searching operation.

Demo projects:

  • Standalone - 6093 : up-thea

Here are the all the apis that Ux.Jooq class provided for paging, sorting

  • Future<JsonObject> searchAndAsync(Inquiry inquiry)
  • Future<JsonObject> searchAndAsync(Inquiry inquiry, String pojo)
  • <T> Future<List<T>> searchAndListAsync(Inquiry inquiry)
  • Future<JsonObject> searchOrAsync(Inquiry inquiry)
  • Future<JsonObject> searchOrAsync(Inquiry inquiry, String pojo)
  • <T> Future<List<T>> searchOrOrListAsync(Inquiry inquiry)

In current version, zero system provided above three apis only, if you want to use dto, you must provide the mapping up.god.file that has been introduced in previous tutorial:

src/main/resources/pojo/tabular.yml

type: "up.god.domain.tables.pojos.SysTabular"
mapping:
  pkId: key
  isActive: active
  zsigma: sigma
  zlanguage: language
  zcreateTime: createTime
  scode: code
  stype: type
  iorder: order
  sname: name
columns:
  name: S_NAME
  code: S_CODE
  type: S_TYPE
  order: I_ORDER
  language: Z_LANGUAGE
  createTime: Z_CREATE_TIME
  updateTime: Z_UPDATE_TIME
  active: IS_ACTIVE
  sigma: Z_SIGMA

1. Source Code

1.1. Api

package up.god.micro.advanced;

import io.vertx.up.annotations.Address;
import io.vertx.up.annotations.EndPoint;

import jakarta.ws.rs.BodyParam;
import javax.ws.rs.POST;
import javax.ws.rs.Path;

@EndPoint
@Path("/api")
public interface SearchApi {
    @Path("tabular/search")
    @POST
    @Address("ZERO://QUEUE/SEARCH")
    String search(@BodyParam String name);
}

Because we'll serialize the body data into Inquiry directly, here we recommend to use POST instead of GET method do searching.

1.2. Consumer

package up.god.micro.advanced;

import io.vertx.core.Future;
import io.vertx.core.json.JsonObject;
import io.vertx.up.unity.Ux;
import io.vertx.up.annotations.Address;
import io.vertx.up.annotations.Queue;
import io.vertx.up.commune.Envelop;

import jakarta.inject.Inject;

@Queue
public class SearchWorker {

    @Inject
    private transient SearchStub searchStub;

    @Address("ZERO://QUEUE/SEARCH")
    public Future<JsonObject> search(final Envelop envelop) {
        final JsonObject data = Ux.getJson(envelop);
        // The second parameter is the yml up.god.file name "tabular.yml"
        return this.searchStub.search(Ux.getInquiry(data, "tabular"));
    }
}

1.3. Stub ( Interface )

package up.god.micro.advanced;

import io.vertx.core.Future;
import io.vertx.core.json.JsonObject;
import io.vertx.up.atom.query.Inquiry;

public interface SearchStub {

    Future<JsonObject> search(final Inquiry inquiry);
}

1.4. Service ( Implementation )

package up.god.micro.advanced;

import io.vertx.core.Future;
import io.vertx.core.json.JsonObject;
import io.vertx.up.unity.Ux;
import io.vertx.up.atom.query.Inquiry;
import up.god.domain.tables.daos.SysTabularDao;

public class SearchService implements SearchStub {
    @Override
    public Future<JsonObject> search(final Inquiry inquiry) {
        return Ux.Jooq.on(SysTabularDao.class)
                .searchAndAsync(inquiry, "tabular");
    }
}

2. Points for searching

  • Here we used Ux.getInquiry api to build valid Inquiry object, the type of this object is io.vertx.up.atom.query.Inquiry.
  • If you do not provide pojo mapping up.god.file ( The 2nd argument ), you should put SQL COLUMN instead instead of field name in sorter and criteria request json node.

3. Testing

Here we prepared different cases to test this searching api.

URL : http://localhost:6093/api/tabular/search

Method : POST

3.1. Empty Request

4. Summary

From this chapter you should know how to do common searching with zero system Jooq.

  • sorter, pager, projection, criteria are specific parameters if you use body directly;
  • sorter and criteria support SQL column usage directly if you do not use pojo argument;
  • projection could remove some returned fields, if you use pojo up.god.file, projection field names should be configured in mapping node.
  • criteria support zero filter syntax in previous tutorial introduced and all the connector is AND in SQL;
  • The returned data format is fixed as you see in examples.
