processor-factory

简单的处理器工厂。

可以在编译期间对枚举类进行解析并且生成一个对应的常量类。

enum demo

@MappingConstant(withEnumName = true)
public enum  UserEnum implements IErrorCode {

    /**
     * 错误码
     */
    PASSWORD_ERROR(1002, "密码错误, 用户名: {0}"),

    USERNAME_ERROR(1001, "用户名错误, 用户名: {0}"),

    USER_NOT_EXIST(1000, "用户不存在, 用户名: {0}");

    private final int code;

    private final String msg;


    UserEnum(int code, String msg) {
        this.code = code;
        this.msg = msg;
    }

    @Override
    public String getMsg() {
        return this.msg;
    }

    @Override
    public int getCode() {
        return this.code;
    }
}

constant at java compile

public final class UserEnumConstant {
  private UserEnumConstant() {
  }

  public static final class PasswordError {
    public static final String NAME = "PASSWORD_ERROR";

    public static final int CODE = 1002;

    public static final String MSG = "密码错误, 用户名: {0}";

    private PasswordError() {
    }
  }

  public static final class UsernameError {
    public static final String NAME = "USERNAME_ERROR";

    public static final int CODE = 1001;

    public static final String MSG = "用户名错误, 用户名: {0}";

    private UsernameError() {
    }
  }

  public static final class UserNotExist {
    public static final String NAME = "USER_NOT_EXIST";

    public static final int CODE = 1000;

    public static final String MSG = "用户不存在, 用户名: {0}";

    private UserNotExist() {
    }
  }
}

可以拷贝实体类生成新的实体类，如DTO，VO等。

demo entity

@MappingModel(suffixName = "DTO", excludeFields = {"createdBy"}, addFieldClasses = {DeliveryOrderField.class})
@MappingModel(suffixName = "VO", packageName = "com.heimdall.processor.demo.model.vo", includeFields = {"id", "createdAt","deliveryOrderProducts", "deliveryOrderItems"})
public class DeliveryOrderData {

    private Long id;
    
    private Date createdAt;

    private Long createdBy;

    private List<DeliveryOrderProductData> deliveryOrderProducts;

    private DeliveryOrderStatusEnum status;

    private List<DeliveryOrderItemData> deliveryOrderItems;

}

entity at java compile

public class DeliveryOrderDataDTO {
  private Long id;

  private Date createdAt;

  private DeliveryOrderProductDataDTO deliveryOrderProducts;

  private DeliveryOrderStatusEnum status;

  private DeliveryOrderItemDataDTO deliveryOrderItems;

  private Integer version;

  public Long getId() {
    return this.id;
  }

  public DeliveryOrderDataDTO setId(Long id) {
    this.id = id;
    return this;
  }

  public Date getCreatedAt() {
    return this.createdAt;
  }

  public DeliveryOrderDataDTO setCreatedAt(Date createdAt) {
    this.createdAt = createdAt;
    return this;
  }

  public DeliveryOrderProductDataDTO getDeliveryOrderProducts() {
    return this.deliveryOrderProducts;
  }

  public DeliveryOrderDataDTO setDeliveryOrderProducts(
      DeliveryOrderProductDataDTO deliveryOrderProducts) {
    this.deliveryOrderProducts = deliveryOrderProducts;
    return this;
  }

  public DeliveryOrderStatusEnum getStatus() {
    return this.status;
  }

  public DeliveryOrderDataDTO setStatus(DeliveryOrderStatusEnum status) {
    this.status = status;
    return this;
  }

  public DeliveryOrderItemDataDTO getDeliveryOrderItems() {
    return this.deliveryOrderItems;
  }

  public DeliveryOrderDataDTO setDeliveryOrderItems(DeliveryOrderItemDataDTO deliveryOrderItems) {
    this.deliveryOrderItems = deliveryOrderItems;
    return this;
  }

  public Integer getVersion() {
    return this.version;
  }

  public DeliveryOrderDataDTO setVersion(Integer version) {
    this.version = version;
    return this;
  }

  @Override
  public String toString() {
    return "DeliveryOrderDataDTO{id=" + id +
        ", createdAt=" + createdAt +
        ", deliveryOrderProducts=" + deliveryOrderProducts +
        ", status=" + status +
        ", deliveryOrderItems=" + deliveryOrderItems +
        ", version=" + version +
        "}";
  }
}
