java - @Embeded Entity 用于只读 Spring Data Jdbc

问题描述

我正在尝试repo.findAll()使用@Embeded注释name通过其statusid 作为外键获取对象的状态，但得到异常。

表：

CREATE TABLE `contract_statuses` (
    `id` int(11) NOT NULL AUTO_INCREMENT,
    `name` varchar(45) NOT NULL,
    PRIMARY KEY (`id`)
);

CREATE TABLE `suppliers_contracts` (
    `id` bigint(20) NOT NULL AUTO_INCREMENT,
    `supplier` bigint(20) NOT NULL,
    `cabs_id` int(11) DEFAULT NULL,
    `start_date` date DEFAULT NULL,
    `end_date` date DEFAULT NULL,
    `attorny_end_date` date DEFAULT NULL,
    `number_of_payments` int(11) DEFAULT NULL,
    `payment_amount` int(11) DEFAULT NULL,
    `comments` varchar(2000) DEFAULT NULL,
    `close_date` timestamp NULL DEFAULT NULL,
    `status` int(11) NOT NULL,
    `created_on` timestamp NOT NULL DEFAULT current_timestamp(),
     PRIMARY KEY (`id`)
);

状态对象

@Table("contract_statuses")
public class ContractStatuses {
      //@Id
      Integer id;
      String name;
     public ContractStatuses() {}       
}

Contract Object:  

@Table("suppliers_contracts")
public class SupplierContractReadOnly {
      @Id
      Long id;
      Long supplier;
      Long cabsId;
      Date startDate;
      Date endDate;
      int paymentAmount;
      Integer status;
      Date attornyEndDate;
      int numberOfPayments;
      String comments;
      Date closeDate;
  
      @MappedCollection(idColumn = "id")
      @Embedded(onEmpty = USE_NULL)
      ContractStatuses statuses;
    
      public SupplierContractReadOnly() { }
        //Getters and setters
}

回购

public interface SupplierContractRepoReadOnly extends Repository<SupplierContractReadOnly,Long> {
    List<SupplierContractReadOnly> findAll();
}

看法

@GetMapping("/getContracts")
public List<SupplierContractReadOnly> getContracts(){
    //List<SupplierContractReadOnly>  newContract = supplierContractRepoReadOnly.findAll();
    return supplierContractRepoReadOnly.findAll();
}

当我将嵌入式实体的引用（在 SupplierContractReadOnly 中）更改为调解器对象时，如下所示：

public class ContractStatusesRef {
    Integer status;
    @MappedCollection(idColumn = "id")
    ContractStatuses contractStatuses;
    public ContractStatusesRef() {
    }
}

例外是不同的：

解决方案

@Embedded意味着虽然被引用的对象在事物的 java 端是一个单独的实体，但它是映射到父实体的表的一部分。

因此，您需要在表中包含ContractStatuses实体的suppliers_contracts列。

这当然会导致名称冲突，因此您需要在@Embedded注释中指定一个前缀，并将该前缀与来自ContractStatuses.

注意：由于这是来自https://stackoverflow.com/a/64025347/66686的后续问题，建议使用数据库视图，因此suppliers_contracts您将映射SupplierContractReadOnly到数据库视图而不是表，然后包含所有上面讨论的列。

另一个注意事项：@MappedCollection仅适用于集合类字段（List和Set）Map。所以在这种情况下它没有任何作用，应该被删除。
