玩！framework bootstrap(Fixtures.loadModels("initial-data.yaml))，在模型的setter中注入"random"字符串值

Question

我有一个具有持久DateTime字段的模型类，该字段仅通过瞬态属性，String date;和String time;的getter/setter进行交互。执行一些非常特殊的格式化来创建DateTime对象，该对象将在需要时持久化或检索。

问题是，当我的模型从yaml文件加载时，time字段的setter接收到一个字符串值，该值根本不对应于我的项目/代码中的任何内容。

这是只有相关成员的类:

package models;
import javax.persistence.*;
import org.hibernate.annotations.*;
import org.joda.time.*;
import org.joda.time.format.*;
import play.db.jpa.*;
@javax.persistence.Entity
public class Booking extends Model {
  @Column
  @Type(type = "org.joda.time.contrib.hibernate.PersistentDateTime")
  public DateTime datetime;
  public Integer duration;
  @Transient
  public String date;
  @Transient
  public String time;    
  //default constructor called by play's model loader that sets default values that are required for the getters and setters to work.
  public Booking() {
    DateTimeFormatter fmt = DateTimeFormat.forPattern("'ISO8601':yyyy-MM-dd'T'HH:mm:ssZ");
    this.datetime = fmt.parseDateTime("ISO8601:1970-01-01T00:00:00+0200");
    //this.datetime = fmt.parseDateTime(this.date+"T"+this.time);
  }
  public void setDate(String dateStr) {    
    this.date = dateStr;
    if (dateStr.contains("ISO")) {
      DateTimeFormatter dt = DateTimeFormat.forPattern("'ISO8601':yyyy-MM-dd'T'HH:mm:ssZ");
      DateTime tmp = dt.parseDateTime(dateStr);
      this.datetime = toDateTime(tmp.toString("yyyy-MM-dd"), getTime());
    } else {
      this.datetime = toDateTime(dateStr, getTime());
    }
  }
  public void setTime(String timeStr) {
    this.time = timeStr; //timeStr = "780" for some reason?!
    if (timeStr.contains("ISO")) {
      DateTimeFormatter dt = DateTimeFormat.forPattern("'ISO8601':yyyy-MM-dd'T'HH:mm:ssZ");
      DateTime tmp = dt.parseDateTime(timeStr);
      this.datetime = toDateTime(getDate(), tmp.toString("HH:mm"));
    }
    this.datetime = toDateTime(getDate(), timeStr);
  }
  public String getDate() {
    DateTimeFormatter format = DateTimeFormat.forPattern("yyyy-MM-dd");
    return this.datetime.toString(format);
  }
  public String getTime() {
    DateTimeFormatter format = DateTimeFormat.forPattern("HH:mm");
    return this.datetime.toString(format);
  }
  private DateTime toDateTime(String dateStr, String timeStr) {
    DateTimeFormatter fmt = ISODateTimeFormat.dateHourMinute();
    DateTime dt = fmt.parseDateTime(dateStr + "T" + timeStr);
    return dt;
  }

当我运行调试器时，setTime第一次调用时收到的timeStr参数是"780"。在我的yaml文件中没有这样的值，因为模型是这样注入的:

Booking(bobBooking):
  date: 2011-09-16
  time: 13:00
  duration: 30
  headcount: 10
  room: b
  user: bob
  description: Bob's Booking.

省略附加字段

Answer 1

尝试在yaml文件中使用引号表示时间值。使用SnakeYAML解析器(这是Play中的默认值)解析冒号字段时可能会出现一些问题

Answer 2

YAML 1.1将13:00定义为十六进制值(这不是您所期望的)

http://yaml.org/type/int.html

使用单引号或双引号指定字符串值。("13","13")
