Java Spring boot:保存具有oneToMany关系的实体时出错

我有两个实体：

category

拥有

oneToMany

产品

这些课程有：

Product.java

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

    @Column(name = "NAME")
    private Long NAME;

    @ManyToOne
    @JoinColumn(name="CATEGORY_ID", nullable = false)
    private Category category;

    //...getters, setters and toString

Category.java：

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

        @Column(name = "NAME")
        private Long NAME;

        @OneToMany(cascade = CascadeType.ALL, mappedBy = "category", orphanRemoval = true)
        private List<Product> products;

        //...getters, setters and toString

但是我得到了一个

500状态

，这就是错误：

00:04:08.940 [http-nio-8080-exec-2] WARN  org.hibernate.engine.jdbc.spi.SqlExceptionHelper - SQL Error: 1747, SQLState: 42000

请注意，我使用的是

oracle

和

flyway

。这是产品

SQL

脚本：

CREATE TABLE "PRODUCT"
   (  "ID" NUMBER(10,0),
  "NAME" VARCHAR2(255 CHAR),
  "CATEGORY_ID" NUMBER(10,0)
   );

CREATE UNIQUE INDEX "PRODUCT_ID_IDX" ON "PRODUCT" ("ID");

ALTER TABLE "PRODUCT" MODIFY ("ID" NOT NULL ENABLE);

ALTER TABLE "PRODUCT" ADD PRIMARY KEY ("ID");

ALTER TABLE "PRODUCT" MODIFY ("CATEGORY_ID" NOT NULL ENABLE);

   CREATE TABLE "CATEGORY"
      ( "ID" NUMBER(19,0),
    "NAME" VARCHAR2(255 CHAR)
      );

  CREATE UNIQUE INDEX "CAT_ID_IDX" ON "CATEGORY" ("ID");

  ALTER TABLE "CATEGORY" MODIFY ("ID" NOT NULL ENABLE);

  ALTER TABLE "CATEGORY" ADD PRIMARY KEY ("ID");

这是我的分类

SQL

脚本：

CREATE TABLE "PRODUCT"
   (  "ID" NUMBER(10,0),
  "NAME" VARCHAR2(255 CHAR),
  "CATEGORY_ID" NUMBER(10,0)
   );

CREATE UNIQUE INDEX "PRODUCT_ID_IDX" ON "PRODUCT" ("ID");

ALTER TABLE "PRODUCT" MODIFY ("ID" NOT NULL ENABLE);

ALTER TABLE "PRODUCT" ADD PRIMARY KEY ("ID");

ALTER TABLE "PRODUCT" MODIFY ("CATEGORY_ID" NOT NULL ENABLE);

   CREATE TABLE "CATEGORY"
      ( "ID" NUMBER(19,0),
    "NAME" VARCHAR2(255 CHAR)
      );

  CREATE UNIQUE INDEX "CAT_ID_IDX" ON "CATEGORY" ("ID");

  ALTER TABLE "CATEGORY" MODIFY ("ID" NOT NULL ENABLE);

  ALTER TABLE "CATEGORY" ADD PRIMARY KEY ("ID");

在SQL文件中，您没有在

CATEGORY\u ID

列上添加外键约束，该约束的长度必须与

CATEGORY

表中的

ID

列相同

您可以这样做：

Alter TABLE PRODUCT
MODIFY "CATEGORY_ID" NUMBER(19,0);

ALTER TABLE PRODUCT
ADD CONSTRAINT FK_CategoryProduct
FOREIGN KEY (CATEGORY_ID) REFERENCES CATEGORY(ID);

假设错误与

oneTomany

关系无关。堆栈跟踪抱怨

无效的user.table.column

。我想问题就在那里。请共享涉及该操作的用户表和代码。因此，问题出在sql脚本上，而不是java代码？@Llg我没有发现与共享java代码中显示的异常相关的问题。很抱歉，迁移失败：

sql状态：22019错误代码：911消息：ORA-00911:无效字符

，即使我有创建了“Product”表，我提到“CATEGORY_ID”是数字（10,0）？我测试了它，但我遇到了同样的问题
