Question

在将实体保存到RDS上的数据库时遇到了问题。这个问题超出了我的理解范围，因为当我在计算机上执行应用程序时， save可以正常工作。即来自Intellij（不知道提到Intellij是否值得）。

这是实体类

@Entity
@Table(name = "spr_material")

public class SprMaterial {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "id")
private Integer id;

@CreationTimestamp
@Column(name = "created_at", nullable = false, updatable = false)
public Timestamp createdAt;

@Column(name = "service_name")
public String serviceName;

@UpdateTimestamp
@Column(name = "updated_at")
public Timestamp updatedAt;

@Column(name = "isDeleted")
private Boolean isDeleted;

@Transient
private int serialNo;


@ManyToOne()
@JoinColumn(name = "dep_id", nullable = true)
private Department department;

@ManyToOne()
@JoinColumn(name = "item_code", nullable = true)
private StockRawMaterial rawMaterial;

// removing get/set methods

@Override
public String toString() {
    return "ID: "+this.id+ " Created At: "+this.createdAt+ " Service Name: "+this.serviceName+ " Deleted: "+this.isDeleted
            + " Department Id: "+this.department.getDepId()+ " Raw Material Id: "+this.rawMaterial.getRawMaterialId();
    }
}

这是将数据保存到数据库的代码块

在Controller类中

@PostMapping("/spr/save")
public String sprMaterial_save(@ModelAttribute("sprForm") SprForm sprForm, RedirectAttributes redirectAttributes) {

    SprMaterial sprMaterial = new SprMaterial();
    sprMaterial.setId(sprMaterialService.getMaxId());
    sprMaterial.setServiceName(sprForm.getServiceName());
    sprMaterial.setRawMaterial(rawMaterialService.findById(sprForm.getItemCode()));
    sprMaterial.setDepartment(departmentService.findByDeptId(sprForm.getDepartmentId()));
    //sprMaterial.setDeleted(false);
    logger.info("TESTING");
    SprMaterial saved = sprMaterialService.save(sprMaterial);
    if(saved == null){
        System.out.println("Could not saved object");
    }else {
        System.out.println("Saved Successful");
    }
    redirectAttributes.addFlashAttribute("addedSuccess", "success");
    return "redirect:/spr/accounts";
}

在服务舱中

@Override
    public SprMaterial save(SprMaterial sprMaterial) {
        logger.info("SAVING SPR MATERIAL: "+sprMaterial.toString());
        SprMaterial rm = sprRepository.save(sprMaterial);
        logger.info("after saving: "+rm.toString());
        return rm;
    }

更新：我正在使用jpa默认的save方法。这是存储库类。

public interface SprRepository extends JpaRepository<SprMaterial, Integer> {
    @Query(value = "SELECT spr.* FROM spr_material spr JOIN department d ON d.dep_id = spr.dep_id WHERE d.name LIKE ?1 AND spr.isDeleted = FALSE ORDER BY ?#{#pageable}",
            countQuery = "SELECT spr.* FROM spr_material spr JOIN department d ON d.dep_id = spr.dep_id WHERE d.name LIKE ?1 AND spr.isDeleted = FALSE ORDER BY ?#{#pageable}", nativeQuery = true)
    Page<SprMaterial> findSprMaterialById(String name, Pageable pageable);

    @Modifying
    @Transactional
    @Query(value = "UPDATE spr_material spr SET spr.`isDeleted` = 1 WHERE spr.`id` = ?1", nativeQuery = true)
    void deleteSprMaterial(Integer sprMaterialId);

    SprMaterial findById(Integer sprMaterialId);

    @Query(value = "SELECT MAX(spr.`id`) + 1 FROM spr_material spr",nativeQuery = true)
    Integer getMaxId();

    @Query(value = "select * from spr_material spr where spr.`dep_id`=?1",nativeQuery = true)
    SprMaterial findByDepId(Integer deptId);

}

在tomcat catalina.out上，我得到以下日志，并得到一个页面，该页面的错误为504
