Posted 2023-02-27

【中文标题】在 Spring Boot 应用程序中找不到类型现金流的属性日期

【英文标题】：No property date found for type cashflow in Springboot app

【发布时间】：2020-03-22 22:31:22

【问题描述】：

我正在用实体、存储库、服务、控制器设计模式编写关于现金流实体的休息服务。

实体：-

import java.io.Serializable;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.validation.constraints.NotBlank;

import org.hibernate.annotations.NaturalId;

@Entity
@Table(name = "cashflow")
public class Cashflow implements Serializable 

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @NaturalId
    @NotBlank
    private String entityId;

    @Column(nullable = false)
    private String companyId;

    @Column
    private boolean isDeleted = true;

    public Long getId() 
        return id;
    

    public void setId(Long id) 
        this.id = id;
    

    public String getEntityId() 
        return entityId;
    

    public void setEntityId(String entityId) 
        this.entityId = entityId;
    

    public String getCompanyId() 
        return companyId;
    

    public void setCompanyId(String companyId) 
        this.companyId = companyId;
    

    public boolean isDeleted() 
        return isDeleted;
    

    public void setDeleted(boolean isDeleted) 
        this.isDeleted = isDeleted;
    

存储库：-

import java.util.List;

import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.data.repository.PagingAndSortingRepository;
import org.springframework.stereotype.Repository;

@Repository
public interface CashflowRepository extends PagingAndSortingRepository<Cashflow, Long> 
    Page<Cashflow> findAllByCompanyIdAndIsDeleted(String companyId, boolean flag, Pageable pageable);

    public Cashflow findByEntityId(String entityId);

    public List<Cashflow> findAllByEntityIdIn(List<String> entityIds);

服务：-

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.PageRequest;
import org.springframework.data.domain.Pageable;
import org.springframework.data.domain.Sort;
import org.springframework.stereotype.Service;

@Service
public class CashflowService 

    @Autowired
    private CashflowRepository cashflowRepository;

    public Page<Cashflow> findByCompanyId(String companyId, Integer pageNo, Integer pageSize, String sortBy) 
        Pageable paging = PageRequest.of(pageNo, pageSize, Sort.by(sortBy));
        Page<Cashflow> pagedResult = cashflowRepository.findAllByCompanyIdAndIsDeleted(companyId, false, paging);
        return pagedResult;
    

控制器：-

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Page;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@CrossOrigin
@RestController
public class CashflowController 

    @Autowired
    private CashflowService cashflowService;

    @GetMapping(value = "/companyId/settlement/cashflows")
    public Page<Cashflow> findParcels(@PathVariable("companyId") String companyId, @RequestParam(defaultValue = "0") Integer pageNo, @RequestParam(defaultValue = "10") Integer pageSize, @RequestParam(defaultValue = "date") String sortBy) 
        return cashflowService.findByCompanyId(companyId, pageNo, pageSize, sortBy);
    

当我调用服务时，它给出了以下错误：-

我已经基于相同的设计模式构建了 REST api，它对我来说效果很好。我不明白，为什么它说“没有找到类型现金流的属性日期！”？无论如何，实体中没有日期属性。我尝试删除数据库并重新开始，但没有奏效。我错过了什么？

【问题讨论】：

您正在发送一个带有名为 date 的 orderBy 的请求。您的传入请求包含无效的属性名称

是的，我从另一个班级复制了该代码，完全错过了更改它的机会。请在答案中给出答案而不是 cmets 部分，以便我可以接受它作为正确答案。它会帮助别人。

这清楚地表明，在生成排序子句时，它会在未知属性上中断。排序是根据您在控制器中构造的传入的Pageable 完成的。构造依赖于传入的请求参数sortBy，其默认值为date。

现在，当参数不存在时，将使用此值，因为您的实体没有date 属性，它将中断。

删除排序或提供有效的默认值。
