如何访问属性？

Question

从 1.4.0 版本开始， "PropertyChange is now decoupled from Property, reference from propertyChange to concrete property is replaced with propertyName String field."

1.4.0 更改后访问属性的替代方法是什么？因为我想在属性

中访问 "looksLikeId"

Answer 1

您可以使用以下代码片段完成此操作：

ManagedType managedType = (ManagedType)javers.getTypeMapping(Person.class);
Property property = managedType.getProperty(propertyChange.getPropertyName());

完整示例（groovy）：

def "should extract Property from PropertyChange"(){
  given:
  def javers = JaversTestBuilder.newInstance()

  when:
  def diff = javers.compare(new Person('1','bob'), new Person('1','bobby'))
  PropertyChange propertyChange = diff.changes[0]

  ManagedType managedType = (ManagedType)javers.getTypeMapping(Person)
  Property property = managedType.getProperty(propertyChange.propertyName)

  then:
  property.name == 'name'
  !property.looksLikeId()
}

在 1.4.1 版本中，我将为 javers 添加方便的 getProperty() 方法：

Property property = javers.getProperty( propertyChange )
