JavaFX属性和绑定02
对于简单的包装类型，JavaFX针对性地提供了对应的Property，如StringProperty、IntegerProperty等。但在实际的业务场景中，我们还需要处理一些自定义数据类型、一对一、一对多关系等。在JavaFx中，可以使用ObjectProperty和ListProperty来实现。
ObjectProperty可以用于实现复杂对象的一对一关系，ListProperty可以用于实现复杂对象的一对多关系。
这是最常见的数据结构（Java Bean/POJO），对应数据库表。
指一个业务实体中，除了一些简单类型的属性外，还拥有以1:1、1:n方式关联的其它业务实体。即MyBatis中的association和collection。
聚合可以是一主一子、一主多子、多主一子、多主多子、多主等形式。
指两个业务实体之间存在的交叉引用关系。例如，用户实体和角色实体。一个用户可以拥有多个角色，一个角色也可以分配给多个用户。多对多关系一般使用一张独立的表来保存为种关系。
数据库物理模型中，必须有上级节点、是否末级，这两个字段是用于构造树形结构。可选“当前层级”、“当前层级顺序”字段，用于数据排序。 元数据信息中，需要指定唯一排序字段，用于在没有指定“当前层级”、“当前层级顺序”时进行排序。
既要展现方便，如枚举、参照等信息，在UI中要显示为业务人员能够看懂的信息，而不是主键、编码等没有业务意义的信息。 又要数据库设计结构合理，满足或基本满足数据库第三范式的要求。如不能在集团基本信息表中，保存“国家地区”的编码、名称等信息。 还要满足效率尽量优化、性能尽量高、资源占用尽量少等性能要求。要尽量减少访问数据库的次数，减少构造复杂结构的对象。
其中包含JavaFX的包装类型、新的日期时间类型、自定义枚举类型、参照类型、List类型等。
private String testCode;
private String testName;
private Byte testByte;
private Short testShort;
private Long testLong;
private Boolean testBoolean;
private LocalTime testTime;
private LocalDateTime testDateTime;
// 自定义枚举类型
private ValueObjectStatusEnum valueObjectStatus;
private Integer testInteger;
private BigDecimal testDecimal;
private LocalDate testDate;
// 自定义参照类型
private UserReferenceVO pkUser;
// List
private List<SubVO> listChild = new ArrayList<>();
public Integer getTestInteger() {
return testInteger;
}
public void setTestInteger(Integer testInteger) {
Integer oldValue = getTestInteger();
this.testInteger = testInteger;
firePropertyChange("testInteger", oldValue, testInteger);
}
/**
* 属性值变化监听器，用于在javaFX体系下监听属性值的变化，实现双向监听，以保证FXVO和VO中的属性值的一致性
* 该监听器的作用非常重要。所有需要使用FX体系进行包装的VO，在setter中，都必须使用本监听器通知FX来感知属性值的变化。
* <p>
* {@link com.lirong.eap.platform.metadata.pub.vo.PropertyVO}
*/
@DiffIgnore
protected final PropertyChangeSupport propertyChangeSupport = new PropertyChangeSupport(this);
/**
* 属性变化事件
*
* @param propertyName 属性名称
* @param oldValue 原值
* @param newValue 新值
*/
public void firePropertyChange(String propertyName, Object oldValue, Object newValue) {
propertyChangeSupport.firePropertyChange(propertyName, oldValue, newValue);
}
用于前台界面进行数据处理。由于JavaFX Property不支持序列化机制，所以只能从后台接受Bean，然后封装为JavaFX Bean供前台使用。
private TestVO testVO;
private StringProperty testCode;
private StringProperty testName;
private ObjectProperty<Byte> testByte;
private ObjectProperty<Short> testShort;
private ObjectProperty<Long> testLong;
private ObjectProperty<Boolean> testBoolean;
private ObjectProperty<LocalTime> testTime;
private ObjectProperty<LocalDateTime> testDateTime;
// 自定义枚举类型
private ObjectProperty<ValueObjectStatusEnum> valueObjectStatus;
private ObjectProperty<Integer> testInteger;
private ObjectProperty<BigDecimal> testDecimal;
private ObjectProperty<LocalDate> testDate;
// 自定义参照类型
private ObjectProperty<UserReferenceVO> pkUser;
// List
private ListProperty<SubFXVO> listChild;
FXVO的构造器，应以VO为参数，以便于获取VO传递给后台。
public TestFXVO(TestVO testVO) {
super();
setTestVO(testVO);
initProperty();
}
protected void initProperty() {
try {
// 简单对象
testCode = JavaBeanStringPropertyBuilder.create().bean(this.testVO).name("testCode").build();
testName = JavaBeanStringPropertyBuilder.create().bean(this.testVO).name("testName").build();
testInteger = JavaBeanObjectPropertyBuilder.create().bean(this.testVO).name("testInteger").build();
testDecimal = JavaBeanObjectPropertyBuilder.create().bean(this.testVO).name("testDecimal").build();
testDate = JavaBeanObjectPropertyBuilder.create().bean(this.testVO).name("testDate").build();
testByte = JavaBeanObjectPropertyBuilder.create().bean(this.testVO).name("testByte").build();

testTime = JavaBeanObjectPropertyBuilder.create().bean(this.testVO).name("testTime").build();
testDateTime = JavaBeanObjectPropertyBuilder.create().bean(this.testVO).name("testDateTime").build();
valueObjectStatus = JavaBeanObjectPropertyBuilder.create().bean(this.testVO).name("valueObjectStatus").build();
// 参照
pkUser = JavaBeanObjectPropertyBuilder.create().bean(this.testVO).name("pkUser").build();
listChild = new SimpleListProperty<>(FXCollections.observableArrayList());
// vo -> fxvo
getValueObject().getListChild().forEach(vo -> getListChild().add(new SubFXVO(vo)));
// fxvo -> vo
listChild.addListener((ListChangeListener<SubFXVO>) change -> {
while (change.next()) {
if (change.wasAdded()) {
for (SubFXVO subFXVO : change.getAddedSubList()) {
getValueObject().getListChild().add(subFXVO.getValueObject());
}
} else if (change.wasRemoved()) {
for (SubFXVO subFXVO : change.getRemoved()) {
getValueObject().getListChild().remove(subFXVO.getValueObject());
}
}
}
});
} catch (NoSuchMethodException e) {
throw new RuntimeException(e);
}
}
注意对List类型属性的处理方式。

-
从bean的list属性中，移除一个元素，看fx bean是否同步更新
可以发现有问题。bean中的list变化时，fx bean无法感知。
-
从fx bean的list属性中，移除一个元素，看bean是否同步更新
fx bean中的list变化时，会处理bean中的数据。
-
在bean中修改、增加元素
同第一种情况，bean中的元素变化时，fx bean无法感知。
-
在fx bean中，移除、增加、修改参数
fx bean中的list变化时，会处理bean中的数据。
- 对于简单类型的属性(String、Integer、BigDecimal等)来说，能够实现bean、fx bean之间的双向绑定
- 对于复杂类型的属性(List、Set等)来说，fx bean会把元素变化传递给bean，而反之则不行
