@Retention(value=RUNTIME) @Target(value=TYPE) public @interface XmlType
Maps a class or an enum type to a XML Schema type.
Usage
The @XmlType annnotation can be used with the following program elements:
See "Package Specification" in javax.xml.bind.package javadoc for additional common information.
A class maps to a XML Schema type. A class is a data container for values represented by properties and fields. A schema type is a data container for values represented by schema components within a schema type's content model (e.g. model groups, attributes etc).
To be mapped, a class must either have a public zero arg
constructor or a static zero arg factory method. In
the absence of either, XmlJavaTypeAdapter
annotation can
be used to adapt the class. The static factory method can be
specified in factoryMethod() and factoryClass()
annotation elements.
A class maps to either a XML Schema complex type or a XML Schema simple type. The XML Schema type is derived based on the mapping of JavaBean properties and fields contained within the class. The schema type to which the class is mapped can either be named or anonymous. A class can be mapped to an anonymous schema type by annotating the class with @XmlType(name="").
Either a global element, local element or a local attribute can be associated with an anoymous type as follows:
XmlRootElement
. See Example 3 below. Mapping class to XML Schema simple type
A class can be mapped to a XML Schema simple type using the @XmlValue annotation. For additional details and examples, see @XmlValue annotation type.
The following table shows the mapping of the class to a XML Schema complex type or simple type. The notational symbols used in the table are:
Target propOrder ClassBody ComplexType SimpleType Class {} [property]+ -> elements complexcontent
xs:allClass non empty [property]+ -> elements complexcontent
xs:sequenceClass X no property -> element complexcontent
empty sequenceClass X 1 [ @XmlValue property] &&
[property]+ ->attributessimplecontent Class X 1 [ @XmlValue property ]&&
no properties -> attributesimpletype
This annotation can be used with the following annotations:
XmlRootElement
, XmlAccessorOrder
, XmlAccessorType
,
XmlJavaTypeAdapter
, XmlEnum
. However, XmlAccessorOrder
and XmlAccessorType
are ignored when this
annotation is used on an enum type.
Example 1: Map a class to a complex type with xs:sequence with a customized ordering of JavaBean properties.
@XmlType(propOrder={"street", "city" , "state", "zip", "name" }) public class USAddress { String getName() {..}; void setName(String) {..}; String getStreet() {..}; void setStreet(String) {..}; String getCity() {..}; void setCity(String) {..}; String getState() {..}; void setState(String) {..}; java.math.BigDecimal getZip() {..}; void setZip(java.math.BigDecimal) {..}; } <!-- XML Schema mapping for USAddress --> <xs:complexType name="USAddress"> <xs:sequence> <xs:element name="street" type="xs:string"/> <xs:element name="city" type="xs:string"/> <xs:element name="state" type="xs:string"/> <xs:element name="zip" type="xs:decimal"/> <xs:element name="name" type="xs:string"/> </xs:all> </xs:complexType>
Example 2: Map a class to a complex type with xs:all
@XmlType(propOrder={}) public class USAddress { ...} <!-- XML Schema mapping for USAddress --> <xs:complexType name="USAddress"> <xs:all> <xs:element name="name" type="xs:string"/> <xs:element name="street" type="xs:string"/> <xs:element name="city" type="xs:string"/> <xs:element name="state" type="xs:string"/> <xs:element name="zip" type="xs:decimal"/> </xs:sequence> </xs:complexType>
Example 3: Map a class to a global element with an anonymous type.
@XmlRootElement @XmlType(name="") public class USAddress { ...} <!-- XML Schema mapping for USAddress --> <xs:element name="USAddress"> <xs:complexType> <xs:sequence> <xs:element name="name" type="xs:string"/> <xs:element name="street" type="xs:string"/> <xs:element name="city" type="xs:string"/> <xs:element name="state" type="xs:string"/> <xs:element name="zip" type="xs:decimal"/> </xs:sequence> </xs:complexType> </xs:element>
Example 4: Map a property to a local element with anonmyous type.
//Example: Code fragment public class Invoice { USAddress addr; ... } @XmlType(name="") public class USAddress { ... } } <!-- XML Schema mapping for USAddress --> <xs:complexType name="Invoice"> <xs:sequence> <xs:element name="addr"> <xs:complexType> <xs:element name="name", type="xs:string"/> <xs:element name="city", type="xs:string"/> <xs:element name="city" type="xs:string"/> <xs:element name="state" type="xs:string"/> <xs:element name="zip" type="xs:decimal"/> </xs:complexType> ... </xs:sequence> </xs:complexType>
Example 5: Map a property to an attribute with anonmyous type.
//Example: Code fragment public class Item { public String name; @XmlAttribute public USPrice price; } // map class to anonymous simple type. @XmlType(name="") public class USPrice { @XmlValue public java.math.BigDecimal price; } <!-- Example: XML Schema fragment --> <xs:complexType name="Item"> <xs:sequence> <xs:element name="name" type="xs:string"/> <xs:attribute name="price"> <xs:simpleType> <xs:restriction base="xs:decimal"/> </xs:simpleType> </xs:attribute> </xs:sequence> </xs:complexType>

java.lang.Class |
factoryClass
Class containing a zero arg factory method for creating an instance of the annotated class. |
java.lang.String |
factoryMethod
Name of a zero arg factory method in factoryClass() for creating an instance of the annotated class. |
java.lang.String |
name
Name of the XML Schema type which the class is mapped. |

namespace
Name of the target namespace of the XML Schema type. |
java.lang.String[] |
propOrder
Specifies the order for XML Schema elements when class is mapped to a XML Schema complex type. |
public abstract java.lang.String name
public abstract java.lang.String[] propOrder
Refer to the table for how the propOrder affects the mapping of class
The propOrder is a list of names of JavaBean properties in the class. Each name in the list is the name of a Java identifier of the JavaBean property. The order in which JavaBean properties are listed is the order of XML Schema elements to which the JavaBean properties are mapped.
All of the JavaBean properties being mapped to XML Schema elements must be listed. If a JavaBean property is marked with @XmlTransient, then it is ignored.
The default ordering of JavaBean properties is determined
by @XmlAccessorOrder
.
