所以我知道如何创建枚举类型,但是当我为它设置元素类型时,元素字段将只是字符串类型而不是类型枚举。如何在我的模式中创建枚举并让JAXB将其生成为java枚举类型?
这就是我在进行枚举类型和元素创建的方式:
<xsd:simpleType name="myEnum">
<xsd:restriction base="xsd:string">
<xsd:enumeration value="MY_ENUM_1"/>
<xsd:enumeration value="MY_ENUM_2"/>
</xsd:restriction>
</xsd:simpleType>
<xsd:element name="myEnumElement" type="ns1:myEnum"/>

您可以按如下方式构建XML架构:
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema targetNamespace="http://www.example.com" xmlns="http://www.example.com" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:simpleType name="myEnum">
<xsd:restriction base="xsd:string">
<xsd:enumeration value="MY_ENUM_1"/>
<xsd:enumeration value="MY_ENUM_2"/>
</xsd:restriction>
</xsd:simpleType>
<xsd:element name="root">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="local" type="myEnum"/>
<xsd:element name="ref" type="myEnum"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
将导致生成以下枚举:
package com.example;
import javax.xml.bind.annotation.*;
@XmlType(name = "myEnum")
@XmlEnum
public enum MyEnum {
MY_ENUM_1,
MY_ENUM_2;
public String value() {
return name();
}
public static MyEnum fromValue(String v) {
return valueOf(v);
}
}
以下类利用了Enum:
package com.example;
import javax.xml.bind.annotation.*;
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
"local",
"ref"
})
@XmlRootElement(name = "root")
public class Root {
@XmlElement(required = true)
protected MyEnum local;
@XmlElement(required = true)
protected MyEnum ref;
public MyEnum getLocal() {
return local;
}
public void setLocal(MyEnum value) {
this.local = value;
}
public MyEnum getRef() {
return ref;
}
public void setRef(MyEnum value) {
this.ref = value;
}
}
