Override the JAXB property name using a xjb preserving the underscores

问题

The custom xjb works great for overriding the names as desired however we lose the underscores in the names.

<?xml version="1.0" encoding="UTF-8"?>
<jxb:bindings 
  xmlns:xs="http://www.w3.org/2001/XMLSchema"
  xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
  version="2.1">
  <jxb:globalBindings underscoreBinding="asCharInWord"/>
   <jxb:bindings schemaLocation="foo.xsd">
        <jxb:bindings node="//xs:complexType[@name='fooType']">
            <jxb:property name="value" />
        </jxb:bindings>
  </jxb:bindings>
</jxb:bindings>

As you can see for the above xjb the java code generated is

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "textType", propOrder = {
"value"
})
public class FooType {

@XmlMixed
@XmlAnyElement(lax = true)
protected List<Object> value;
......
 public List<Object> getValue() {
    if (value == null) {
        value = new ArrayList<Object>();
    }
    return this.value;
}

Now, once I change one line in the xjb above to:

 <jxb:property name="_value" />

All that changes in the java code is :

public List<Object> get_Value() {
    if (value == null) {
        value = new ArrayList<Object>();
    }
    return this.value;
}

Observed: "value"

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "textType", propOrder = {
"value"
})

Desired: "_value"

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "textType", propOrder = {
"_value"
})

回答1:

The following propOrder is fine since @XmlAccessorType(XmlAccessType.FIELD) is specified and the name of the field is value even though the property is called _Value (see: http://blog.bdoughan.com/2012/02/jaxbs-xmltype-and-proporder.html).

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "textType", propOrder = {
"value"
})

The goal is to have the "value" appear as "_value" in my json

Your particular _Value property appears to be to be able to hold anything. How do you want the contents to be rendered to JSON?

@XmlMixed
@XmlAnyElement(lax = true)
protected List<Object> value;
