spring - 具有相同标识符值的不同对象已与带有 SpringBoot 的会话相关联

问题描述

我的代码有问题，我看过各种类似问题的帖子，但我无法解决我的问题。

我正在用一个小工厂开发一个 Erp，接下来是我的对象模型：

文章
ArticuloCompras 扩展了 Articulo
ArticuloProduccion 扩展了 Articulo

我的模型代码是下一个：对于 Articulo：

@Entity(name="articulos")
@Inheritance(strategy=InheritanceType.JOINED)
public class Articulo {
    
    /*@Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private int id;*/
    @Id
    @Column(unique = true, nullable = false)
    private String codigo;
    private String descripcion;
    @Enumerated(EnumType.STRING)
    private TipoArticulo tipo;
    private boolean ignorarMrp;
    private String plano;
    private String dTecnicos;

对于 ArticuloCOMpra：

@Entity(name="articulos_compra")
@PrimaryKeyJoinColumn(name="codigo")
public class ArticuloCompras extends Articulo {
    
    private boolean granel;
    private String dCompra;
    @ManyToOne//(optional = false, cascade = CascadeType.ALL, fetch = FetchType.EAGER)
    @JoinColumn(name="proveedor_actual_id")
    private Proveedor proveedorActual;

对于 ArticuloProduccion：

@Entity(name="articulos_produccion")
@PrimaryKeyJoinColumn(name="codigo")
public class ArticuloProduccion extends Articulo {
    
    private boolean premontaje;
    //@OneToOne
    @Transient
    private Ruta ruta;
    /*@ManyToMany(cascade = CascadeType.ALL)
    @JoinTable(
            name="articulo_estructura", 
            //joinColumns=@JoinColumn(name="articulo_codigo", referencedColumnName="codigo"), 
            inverseJoinColumns= {
                    @JoinColumn(name="articulo_utilizado", referencedColumnName="articuloUtilizado"), 
                    @JoinColumn(name="fecha_inicio", referencedColumnName="fechaInicio"), 
                    @JoinColumn(name="fecha_fin", referencedColumnName="fechaFin"), 
                    @JoinColumn(name="cantidad", referencedColumnName="cantidad"),
                    @JoinColumn(name="tipo_unidad", referencedColumnName="unidad")}
            )*/
    @Transient
    private List<Utilizado> estructura;

我的视图代码是下一个：

form th:action="@{/articulos/guardar}" th:object="${articulo}" class="form" method="post">
                    <div class="col alert alert-danger" th:if="${#fields.hasErrors('*')}" role="alert">

我的控制器代码是下一个：

@PostMapping("/guardar")
public String guardarArticulo(@RequestParam(value="granel", required = false) boolean granel, @RequestParam(value="premontaje", required = false) boolean premontaje, 
        @RequestParam(value="ignorarMrp", required = false) boolean ignorarMrp, @RequestParam(value="proveedor", required = false) String proveedor, 
        @RequestParam(value="dCompra", required = false) String dCompra, @RequestParam(value="dComercializacion", required = false) String dComercializacion, 
        Articulo articulo, BindingResult result, Model model) {
    if(result.hasErrors()) {
        for(ObjectError error : result.getAllErrors()) {
            System.out.println("Ocurrio un error: " + error.getDefaultMessage());
        }
        return "ArticleViews/createForm";
    }
    
    //Articulo art;
    System.out.println(articulo);
    switch(articulo.getTipo()) {
    case COMPRAS:
        ArticuloCompras art;
        Optional<Proveedor> opProv; //hay que buscar el proveedor segun el id que les pase por aqui y sino añadirlo a la BBDD
        Proveedor objProveedor;
        opProv = this.provRepo.findByCodigo(proveedor);
        if(opProv.isPresent()) {
            objProveedor = opProv.get();
        } else {
            System.out.println("crear proveedor..");
            objProveedor = new Proveedor(); //ojo aqui le paso uno vacio solo para pruevas pero habra que crearlo con su formulario si el usuario quiere.
        }
        art = new ArticuloCompras(articulo, granel, dCompra, objProveedor);
        //this.artRepo.save(art);
        this.artRepo.saveAndFlush(art);
        model.addAttribute("articulo", art);
        System.out.println("El siguiente articulo ha sigo persisitido:\n-------------------------------------------\n" + art);
    case PRODUCCION:
        ArticuloProduccion artP;
        artP = new ArticuloProduccion(articulo, premontaje);
        this.artRepo.saveAndFlush(artP);
        model.addAttribute("articulo", artP);
        System.out.println("El siguiente articulo ha sigo persisitido:\n-------------------------------------------\n" + artP);
    }
    return "ArticleViews/guardar";
}

我想根据用户输入表单来坚持 ArticuloCompras 和 ArticuloProduccion。当我坚持第一个对象时，应用程序可以工作，但是当我尝试坚持其他对象时，我得到下一个错误：
