  • 数据库字段为int类型
  • 实体字段为了可读性强，使用枚举类型
  • 一般来说，数据库为varchar时，你的枚举元素直接会进行转换

字段为整型

  • 这些如果你是mybatis-plus，可以使用如下default-enum-type-handler参数开启@EnumValue特性，将每句的@EnumValue注释的字段添加到数据表字段中。
public enum ModuleType implements NameValueEnum {
  LOGIN(0, "登录"),
  LOGOUT(1, "登出");

  @EnumValue
  private Integer code;
  @JsonValue
  private String name;

  ModuleType(Integer code, String name) {
    this.code = code;
    this.name = name;
  }

  @Override
  public String getName() {
    return name;
  }

  @Override
  public Integer getValue() {
    return code;
  }
}


@Data
@Builder
public class OperatorLog {
  private String id;
  private String dataId;
  private String dataTitle;
  /**
   * 模块类型
   */
  private ModuleType moduleType;
  private String content;
  /**
   * 操作类型
   */
  private OperateType operateType;
}


mybatis-plus:
  default-enum-type-handler: org.apache.ibatis.type.EnumOrdinalTypeHandler
