我有一个图像备份,我恢复到MS SQL服务器2016.我有一个实体声明其ID如下:

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@XmlID
@XmlElement
@XmlJavaTypeAdapter(IntToStringXmlAdapter.class)
private Integer id;

当我保存我收到的实体时:

Hibernate: select next_val as id_val from hibernate_sequence with (updlock, rowlock) 2018-02-28 22:05:41.935 
ERROR 18152 --- [nio-8080-exec-6] o.hibernate.id.enhanced.TableStructure   : could not read a hi value com.microsoft.sqlserver.jdbc.SQLServerException: Invalid object name 'hibernate_sequence'.

我已经手动创建了SQL服务器的序列,并确保它通过SSMS存在.

CREATE SEQUENCE hibernate_sequence
 AS INTEGER
 START WITH 1
 INCREMENT BY 1 …

我正在尝试使用 Angular 5 在选择选项中设置默认值。我已阅读有关 [compareWith] 的内容，但它似乎没有帮助。这是代码：

我的列举：

export enum EncryptionProtocol {
    NONE,
    SSL,
    TLS }

我的配置模型

export class Config implements BaseEntity {
    constructor(
        public id?: number,
        ...
        public encryptionProtocol?: EncryptionProtocol,
        ...
    ) {
    }
}

我的HTML：

    <div class="form-group">
        <label class="form-control-label" for="field_encryptionProtocol">Encryption Protocol</label>
        <select  [compareWith]="compareFn" class="form-control" name="encryptionProtocol" [(ngModel)]="config.encryptionProtocol"
                id="field_encryptionProtocol">
            <option *ngFor="let encryptionProtocol of encryptionProtocolKeys()" [ngValue]="encryptionProtocol">
                {{encryptionProtocol}}
            </option>
        </select>
    </div>

编辑：我的TS：

...
    encryptionProtocols = EncryptionProtocol;

    encryptionProtocolKeys() : Array<string> {
        var keys = Object.keys(this.encryptionProtocols);
        return keys.slice(keys.length / 2);
    }

...

compareFn(c1: EncryptionProtocol, c2: …

我在 Config 和 ConfigHeaders 之间有一对多的关系。这是配置映射器：

@Mapper(componentModel = "spring", uses = {UserMapper.class, ConfigHeadersMapper.class})
public interface ConfigMapper extends EntityMapper<ConfigDTO, Config> {

    @Mapping(source = "user.id", target = "userId")
    ConfigDTO toDto(Config config);

    @Mapping(source = "userId", target = "user")
    @Mapping(target = "messages", ignore = true)
    Config toEntity(ConfigDTO configDTO);

    default Config fromId(Long id) {
        if (id == null) {
            return null;
        }
        Config config = new Config();
        config.setId(id);
        return config;
    }
}

这是 ConfigHeadersMapper：

@Mapper(componentModel = "spring", uses = {ConfigMapper.class})
public interface ConfigHeadersMapper extends EntityMapper<ConfigHeadersDTO, ConfigHeaders> …
