Question

我试图找出如何将代码注入xsd simpleType，这是一个枚举。

我的XSD就像下面的commons.xsd

Text

我的绑定就像下面的

<xsd:simpleType name="tPessoa">
    <xsd:annotation>
        <xsd:documentation>Enumeracao que descreve se e uma pessoa fisica ou
            juridica
            Valores possiveis:
            - pf: para PESSOA FiSICA;
            - pj: para PESSOA
            JURiDICA.
        </xsd:documentation>
    </xsd:annotation>
    <xsd:restriction base="xsd:string">
        <xsd:enumeration value="pf" />
        <xsd:enumeration value="pj" />
    </xsd:restriction>
</xsd:simpleType>

我在maven插件中传递了参数-Xinject-code-extension

但观察到的结果并没有改变。我在StackOverflow中阅读了一些文章，但是我不清楚这是否是JAXB的限制或者我错过了什么。

我的想法是生成一个类，如下所示

<jxb:bindings schemaLocation="../src/main/resources/commons.xsd"
    node="//xsd:schema">
    <jxb:schemaBindings>
        <jxb:package name="my.canonical.commons" />
    </jxb:schemaBindings>

    <jxb:bindings node="/xsd:schema/xsd:simpleType[@name='tPessoa']">
        <ci:code>
            public static TPessoa fromValue(String v) {
            if(("F".equalsIgnoreCase(v)) || ("PF".equalsIgnoreCase(v))) return PF;
            if(("J".equalsIgnoreCase(v)) || ("PJ".equalsIgnoreCase(v))) return PJ;
            throw new IllegalArgumentException(v);
            }
        </ci:code>
    </jxb:bindings>
</jxb:bindings>

因为F和PF是同义词而某些底层系统为同一个实体返回不同的值，所以其中一些返回F其他PF以及J和PJ的相同行为。

怎么做？可能吗？

我从未设法将代码注入到JAXB中的枚举中。我只能将代码注入complexTypes。

下面你可以找到一个替代的例子，它将你问题中的fromValue方法注入一个复杂的类型，也可能很有用。

如果您使用：

运行maven

mvn clean package

您将生成TPessoa课程和PessoaType。后者将包含您指定的静态方法。

PessoaType

package com.fernandes.jaxb;

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlSchemaType;
import javax.xml.bind.annotation.XmlType;


/**
 * <p>Java class for pessoaType complex type.
 * 
 * <p>The following schema fragment specifies the expected content contained within this class.
 *

 * &lt;complexType name="pessoaType"&gt;

 *       &lt;/sequence&gt;
 *     &lt;/restriction&gt;
 *   &lt;/complexContent&gt;
 * &lt;/complexType&gt;

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "pessoaType", propOrder = {
    "type"
})
public class PessoaType {

    @XmlElement(required = true)
    @XmlSchemaType(name = "string")
    protected TPessoa type;

    /**
     * Gets the value of the type property.
     * 
     * @return
     *     possible object is

     */
    public TPessoa getType() {
        return type;
    }

    /**
     * Sets the value of the type property.
     * 
     * @param value
     *     allowed object is
     *     {@link TPessoa }
     *     
     */
    public void setType(TPessoa value) {
        this.type = value;
    }


    public static TPessoa fromValue(String v) {
        if(("F".equalsIgnoreCase(v)) || ("PF".equalsIgnoreCase(v))) return TPessoa.PF;
        if(("J".equalsIgnoreCase(v)) || ("PJ".equalsIgnoreCase(v))) return TPessoa.PJ;

这不是你想要的100％，但它非常接近。
