我有一類定義如下BackendIdConverter.fromRequestId失敗,embeddedId

@Entity 
@Data 
@RestResource 
public class Protocol { 

    private @Version Long version; 
    private @LastModifiedDate @JsonIgnore LocalDateTime lastModifiedDate; 

    //protocol summary level 
    @EmbeddedId ProtocolId protocolId; 
    private Boolean isDefault; 
    private String name; 
    private String patientOrientation; 
    private String patientPosition; 

    //protocol detail level 

} 

@Embeddable 
public class ProtocolId implements Serializable { 
    private String id; 
    private String anatomy; 


    public String getId() { 
     return id; 
    } 

    public String getAnatomy() { 
     return anatomy; 
    } 

    public ProtocolId(String anatomy, String id) { 
     this.anatomy = anatomy; 
     this.id = id; 
    } 

    public ProtocolId() { 

    } 

} 

embeddedId類實現URI爲protocols/anatomy_id,我定義了一個轉換器類如下

@Component 
public class ProtocolIdConverter implements BackendIdConverter { 

    @Override 
    public Serializable fromRequestId(String id, Class<?> entityType) { 
     String[] parts = id.split("_"); 
     return new ProtocolId(parts[0], parts[1]); 
    } 

    @Override 
    public String toRequestId(Serializable source, Class<?> entityType) { 
     ProtocolId id = (ProtocolId)source; 
     return String.format("%s_%s", id.getAnatomy(), id.getId()); 
    } 

    @Override 
    public boolean supports(Class<?> type) { 
     return Protocol.class.equals(type); 
    } 
} 

toRequestId作品罰款,因爲我想,但當fromRequestId被稱爲,例外發生如下

這是怎麼發生的?

想通了。我使用錯誤的ID類型來擴展

你能否詳細說明一下? –
