jaxb - 如何在 xjc 中禁用 Java 命名约定？

Question

例如，xsd 中的 sOmE_PROPerty 必须是 java 类中的 sOmE_PROPerty 而不是 someProperty。

我尝试使用 globalBindings enableJavaNamingConventions="false" 但它不起作用。

Answer 1

您将需要使用underscoreBinding="asCharInWord"而不是enableJavaNamingConventions="false"：

客户.xsd

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema 
    targetNamespace="http://www.example.org/customer" 
    xmlns="http://www.example.org/customer"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    elementFormDefault="qualified"> 

    <xsd:complexType name="customer">
                <xsd:sequence>
                    <xsd:element name="sOmE_PROPerty" type="xsd:string"/>
                </xsd:sequence>
    </xsd:complexType>

</xsd:schema>

绑定.xml

JAXB 绑定文件用于自定义模式到 Java 的转换：

<jaxb:bindings 
    xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
    version="2.1">
    <jaxb:globalBindings underscoreBinding="asCharInWord"/>
</jaxb:bindings>

XJC 呼叫

xjc -d out -b binding.xml customer.xsd

顾客

生成的属性名称现在包含下划线字符：

package org.example.customer;

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

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "customer", propOrder = {
    "sOmEPROPerty"
})
public class Customer {

    @XmlElement(name = "sOmE_PROPerty", required = true)
    protected String sOmEPROPerty;

    public String getSOmE_PROPerty() {
        return sOmEPROPerty;
    }

    public void setSOmE_PROPerty(String value) {
        this.sOmEPROPerty = value;
    }

}

不使用 binding.xml

如果您改为进行以下 XJC 调用：

xjc -d out -customer.xsd

您将看到生成的属性不包含下划线：

package org.example.customer;

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

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "customer", propOrder = {
    "sOmEPROPerty"
})
public class Customer {

    @XmlElement(name = "sOmE_PROPerty", required = true)
    protected String sOmEPROPerty;

    public String getSOmEPROPerty() {
        return sOmEPROPerty;
    }

    public void setSOmEPROPerty(String value) {
        this.sOmEPROPerty = value;
    }

}

Answer 2

通过更改类 com.sun.xml.bind.api.impl.NameConverter 中的 jaxb 的源代码来解决，如下所示：

public static final NameConverter standard = new Standard();

static class Standard extends NameUtil implements NameConverter {
    public String toClassName(String s) {
        return s;//toMixedCaseName(toWordList(s), true);
    }
    public String toVariableName(String s) {
        return s;//toMixedCaseName(toWordList(s), false);
    }
    public String toInterfaceName( String token ) {
        return token;//toClassName(token);
    }
    public String toPropertyName(String s) {
        String prop = s;//toClassName(s);
        // property name "Class" with collide with Object.getClass,
        // so escape this.
        if(prop.equals("Class"))
            prop = "Clazz";
        return prop;
    }
