Flex AMF3 与 Java 数据类型对应表

ActionScript type (AMF 3)

Deserialization to Java

Supported Java type binding

Array (dense)

java.util.List

java.util.Collection, Object[ ] (native array)

If the type is an interface, it is mapped to the following interface implementations:

  • List becomes ArrayList
  • SortedSet becomes TreeSet
  • Set becomes HashSet
  • Collection becomes ArrayList

A new instance of a custom Collection implementation is bound to that type.

Array (sparse)

java.util.Map

java.util.Map

Boolean

String of "true" or "false"

java.lang.Boolean

Boolean, boolean, String

flash.utils.ByteArray

byte []

 

flash.utils.IExternalizable

java.io.Externalizable

 

Date

java.util.Date

(formatted for Coordinated Universal Time (UTC))

java.util.Date, java.util.Calendar, java.sql.Timestamp, java.sql.Time, java.sql.Date

int/uint

java.lang.Integer

java.lang.Double, java.lang.Long, java.lang.Float, java.lang.Integer, java.lang.Short, java.lang.Byte, java.math.BigDecimal, java.math.BigInteger, String, primitive types of double, long, float, int, short, byte

null

null

primitives

Number

java.lang.Double

java.lang.Double, java.lang.Long, java.lang.Float, java.lang.Integer, java.lang.Short, java.lang.Byte, java.math.BigDecimal, java.math.BigInteger, String, 0 (zero)

if null is sent, primitive types of double, long, float, int, short, byte

Object (generic)

java.util.Map

If a Map interface is specified, creates a new java.util.HashMap for java.util.Map and a new java.util.TreeMap for java.util.SortedMap.

String

java.lang.String

java.lang.String, java.lang.Boolean, java.lang.Number, java.math.BigInteger, java.math.BigDecimal, char[], any primitive number type

typed Object

typed Object

When you use [RemoteClass] metadata tag that specifies remote class name. Bean type must have a public no args constructor.

typed Object

undefined

null

null for object, default values for primitives

XML

org.w3c.dom.Document

org.w3c.dom.Document

XMLDocument

(legacy XML type)

org.w3c.dom.Document

org.w3c.dom.Document

You can enable legacy XML support for the XMLDocument type on any channel defined in the services-config.xml file. This setting is important only for sending data from the server back to the client; it controls how org.w3c.dom.Document instances are sent to ActionScript. For more information, see Configuring AMF serialization on a channel.
