@Embeded Entity 只读 Spring 数据 Jdbc
@Embeded Entity for read only Spring Data Jdbc
我正在尝试 repo.findAll() 使用 @Embeded 注释来获取对象的状态 name 通过它的 status id 作为外键但是得到异常。
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();
}
查看
@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）更改为中介对象时，如下所示：
public class ContractStatusesRef {
Integer status;
@MappedCollection(idColumn = "id")
ContractStatuses contractStatuses;
public ContractStatusesRef() {
}
}
例外情况不同：

@Embedded 意味着虽然引用的对象在事物的 java 方面是一个单独的实体，但它是映射到父实体的 table 的一部分。
因此您需要在 suppliers_contracts table 中包含 ContractStatuses 实体的列。
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.[=22= 的列名一起使用]
注意：由于这是 的后续问题，建议使用数据库视图，所以 suppliers_contracts table 你会将 SupplierContractReadOnly 映射到数据库视图，然后包含上面讨论的所有列。
另注：@MappedCollection 仅适用于集合类字段（List、Set 和 Map）。所以它在这种情况下没有任何作用，应该被删除。
我正在尝试 repo.findAll() 使用 @Embeded 注释来获取对象的状态 name 通过它的 status id 作为外键但是得到异常。
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,

@Embedded 意味着虽然引用的对象在事物的 java 方面是一个单独的实体，但它是映射到父实体的 table 的一部分。
因此您需要在 suppliers_contracts table 中包含 ContractStatuses 实体的列。
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.[=22= 的列名一起使用]
注意：由于这是 suppliers_contracts table 你会将 SupplierContractReadOnly 映射到数据库视图，然后包含上面讨论的所有列。
另注：@MappedCollection 仅适用于集合类字段（List、Set 和 Map）。所以它在这种情况下没有任何作用，应该被删除。
