  查询时自定义排序字段和排序规则

  指定字段排序 平台默认排序字段，参考IdModel，按创建时间和ID倒序(ordering = "createDate DESC, id DESC") 方法1：模型指定排序 模型定义增加排序字段。@Model.Advanced(ordering = "xxxxx DESC, yyyy DESC") @Model.model(PetShop.MODEL_MODEL) @Model(displayName = "宠物店铺",summary="宠物店铺",labelFields ={"shopName"}) @Model.Code(sequence = "DATE_ORDERLY_SEQ",prefix = "P",size=6,step=1,initial = 10000,format = "yyyyMMdd") @Model.Advanced(ordering = "createDate DESC") public class PetShop extends AbstractDemoIdModel { public static final String MODEL_MODEL="demo.PetShop"; // ………… } 方法2：Page查询中可以自定排序规则 API参考 pro.shushi.pamirs.meta.api.dto.condition.Pagination#orderBy public <G, R> Pagination<T> orderBy(SortDirectionEnum direction, Getter<G, R> getter) { if (null == getSort()) { setSort(new Sort()); } getSort().addOrder(direction, getter); return this; } 具体示例 @Function.Advanced(type= FunctionTypeEnum.QUERY) @Function.fun(FunctionConstants.queryPage) @Function(openLevel = {FunctionOpenEnum.API}) public Pagination<PetShop> queryPage(Pagination<PetShop> page, IWrapper<PetShop> queryWrapper){ page.orderBy(SortDirectionEnum.DESC, PetShop::getCreateDate); page = new PetShop().queryPage(page, queryWrapper); return page; } 方法3：查询的wapper中指定 API参考：pro.shushi.pamirs.framework.connectors.data.sql.AbstractWrapper#orderBy @Override public Children orderBy(boolean condition, boolean isAsc, R… columns) { if (ArrayUtils.isEmpty(columns)) { return typedThis; } SqlKeyword mode = isAsc ? ASC : DESC; for (R column : columns) { doIt(condition, ORDER_BY, columnToString(column), mode); } return typedThis; } 具体示例 public List<PetShop> queryList(String name) { List<PetShop> petShops = Models.origin().queryListByWrapper( Pops.<PetShop>lambdaQuery().from(PetShop.MODEL_MODEL) .orderBy(true, true, PetShop::getCreateDate) .orderBy(true, true, PetShop::getId) .like(PetShop::getShopName, name)); return petShops; } 设置查询不排序 方法1：关闭平台默认排序字段，设置模型的ordering，改成：ordering = "1=1" 模型定义增加排序字段。@Model.Advanced(ordering = "1=1") @Model.model(PetShop.MODEL_MODEL) @Model(displayName = "宠物店铺",summary="宠物店铺",labelFields ={"shopName"}) @Model.Code(sequence = "DATE_ORDERLY_SEQ",prefix = "P",size=6,step=1,initial = 10000,format = "yyyyMMdd") @Model.Advanced(ordering =…

  自定义createorupdate方法时，关联模型数据怎么保存？

  需要自己手动增加保存关联模型数据的逻辑。 多对一、一对一以及一对多 可直接用fieldSave进行保存即可 //如 data.fieldSave(PamirsEmployee::getPositions); 多对多 需要对数据进行处理，前端提交过来的数据，进行判断，是新增还是修改，或者删除

  如何加密gql请求内容

  介绍 在一些对安全等级要求比较高的场景，oinone提供了扩展前端加密请求内容，后端解密请求内容的能力，该方案要求前后端的加解密方案统一。 后端 1. 继承平台的RequestController新增一个请求类，在里面处理加密逻辑 package pro.shushi.pamirs.demo.core.controller; import org.apache.commons.lang3.StringUtils; import org.springframework.web.bind.annotation.*; import pro.shushi.pamirs.framework.gateways.graph.java.RequestController; import pro.shushi.pamirs.meta.annotation.fun.extern.Slf4j; import pro.shushi.pamirs.meta.api.dto.protocol.PamirsClientRequestParam; import pro.shushi.pamirs.user.api.utils.AES256Utils; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.util.HashMap; import java.util.List; import java.util.Map; @RestController @Slf4j public class DemoRequestController extends RequestController { @SuppressWarnings("unused") @RequestMapping( value = "/pamirs/{moduleName:^[a-zA-Z][a-zA-Z0-9_]+[a-zA-Z0-9]$}", method = RequestMethod.POST ) public String pamirsPost(@PathVariable("moduleName") String moduleName, @RequestBody PamirsClientRequestParam gql, HttpServletRequest request, HttpServletResponse response) { decrypt(gql); return super.pamirsPost(moduleName, gql, request, response); } @SuppressWarnings("unused") @RequestMapping( value = "/pamirs/{moduleName:^[a-zA-Z][a-zA-Z0-9_]+[a-zA-Z0-9]$}/batch", method = RequestMethod.POST ) public String pamirsBatch(@PathVariable("moduleName") String moduleName, @RequestBody List<PamirsClientRequestParam> gqls, HttpServletRequest request, HttpServletResponse response) { for (PamirsClientRequestParam gql : gqls) { decrypt(gql); } return super.pamirsBatch(moduleName, gqls, request, response); } private static final String GQL_VAR = "gql"; private void decrypt(PamirsClientRequestParam gql) { Map<String, Object> variables = null != gql.getVariables() ? gql.getVariables() : new HashMap<>(); String encodeStr = (String) variables.get(GQL_VAR); if (StringUtils.isNotBlank(encodeStr)) { variables.put(GQL_VAR, null); // TODO 此处的加密方法可以换为其他算法 String gqlQuery = AES256Utils.decrypt(encodeStr); gql.setQuery(gqlQuery); } } } 2.boot工程的启动类排除掉平台默认的RequestController类 @ComponentScan( excludeFilters = { // 该注解排除平台的RequestController类 @ComponentScan.Filter( type = FilterType.REGEX, pattern = "pro.shushi.pamirs.framework.gateways.graph.java.RequestController" ) }) public class DemoApplication { } 以下为实际项目中的启动类示例 package pro.shushi.pamirs.demo.boot; import org.apache.ibatis.annotations.Mapper; import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.WebApplicationType; import org.springframework.boot.autoconfigure.SpringBootApplication; import…
