如果我有一个简单的对象,如

class Person {
  String name
  Integer age
}

我可以使用JSONBuilder轻松地将其用户定义的属性呈现为JSON

def person = new Person(name: 'bob', age: 22)

def builder = new JSONBuilder.build {
  person.properties.each {propName, propValue ->

  if (!['class', 'metaClass'].contains(propName)) {

    // It seems "propName = propValue" doesn't work when propName is dynamic so we need to
    // set the property on the builder using this syntax instead
    setProperty(propName, propValue)
  }
}

def json = builder.toString()

当属性很简单时,这可以正常工作,即数字或字符串.但是对于更复杂的对象,例如

class ComplexPerson {
  Name name
  Integer age
  Address address
}

class Name …
