我使用maven插件maven-jaxb2-plugin从XSD Schema文件生成POJO。
这工作正常唯一真正困扰我的是,xml架构枚举没有映射到Java Enum Type中。

我的maven插件是从我称为schemachooser.xsd的文件生成java pojos
schemachooser.xsd:
<?xml version="1.0" encoding="UTF-8"?> <schema xmlns="http://www.w3.org/2001/XMLSchema" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:sch="http://www.ascc.net/xml/schematron" targetNamespace="http://schema.something" elementFormDefault="qualified" version="1.0" xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc" jaxb:extensionBindingPrefixes="xjc" jaxb:version="1.0"> <xs:annotation> <xs:appinfo> <jaxb:globalBindings generateIsSetMethod="true" fixedAttributeAsConstantProperty="true"> <xjc:serializable /> </jaxb:globalBindings> <jaxb:schemaBindings> <jaxb:bindings node="//xsd:element[@name='ElementName']/xsd:simpleType"> <jaxb:typesafeEnumClass name="MyEnumType" /> </jaxb:bindings> </jaxb:schemaBindings> </xs:appinfo> </xs:annotation> <xs:include schemaLocation="myNormalSchema.xsd" /> </schema>
如果要将JAXB注释与XML模式分开,则需要使用JAXB绑定文件:

<jaxb:bindings xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc" jaxb:extensionBindingPrefixes="xjc" version="2.1"> <jaxb:globalBindings generateIsSetMethod="true" fixedAttributeAsConstantProperty="true"> <xjc:serializable /> </jaxb:globalBindings> <jaxb:bindings schemaLocation="myNormalSchema.xsd"> <jaxb:bindings node="//xs:element[@name='ElementName']/xs:simpleType"> <jaxb:typesafeEnumClass name="MyEnumType" /> </jaxb:bindings> </jaxb:bindings> </jaxb:bindings>
myNormalSchema.xsd
下面是一个从您的问题反向设计的示例XML模式:
<?xml version="1.0" encoding="UTF-8"?> <xs:schema targetNamespace="http://www.example.com" xmlns="http://www.example.com" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="ElementName"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:enumeration value="MY_ENUM_1"/> <xs:enumeration value="MY_ENUM_2"/> </xs:restriction> </xs:simpleType> </xs:element> <xs:element name="Root"> <xs:complexType> <xs:sequence> <xs:element ref="ElementName"/> </xs:sequence> </xs:complexType> </xs:element> </xs:schema>
XJC电话
xjc -extension -d out -b bindings.xml myNormalSchema.xsd
MyEnumType
其中一个生成的类是一个名为MyEnumType的枚举。
package com.example; import javax.xml.bind.annotation.XmlEnum; import javax.xml.bind.annotation.XmlType; @XmlType(name = "") @XmlEnum public enum MyEnumType { MY_ENUM_1,MY_ENUM_2; public String value() { return name(); } public static MyEnumType fromValue(String v) { return valueOf(v); } }
根
package com.example; import java.io.Serializable; import javax.xml.bind.annotation.XmlAccessType; import javax.xml.bind.annotation.XmlAccessorType; import javax.xml.bind.annotation.XmlElement; import javax.xml.bind.annotation.XmlRootElement; import javax.xml.bind.annotation.XmlType; @XmlAccessorType(XmlAccessType.FIELD) @XmlType(name = "",propOrder = { "elementName" }) @XmlRootElement(name = "Root") public class Root implements Serializable { @XmlElement(name = "ElementName",required = true) protected MyEnumType elementName; public MyEnumType getElementName() { return elementName; } public void setElementName(MyEnumType value) { this.elementName = value; } public boolean isSetElementName() { return (this.elementName!= null); } }
