如圖，Spring boot 配置註解資訊，

svconfiguration表：

@Entity(name = "SV_CONFIGURATION") @IdClass(SvConfigId.class)
public class SvConfiguration {

    @Id private String key;
    @Id private Integer version;

    private Float value;

    public String getKey() {

    }

        this.key = key;
    }

        return value;
    }

    public void setValue(Float value) {
        this.value = value;
    }
