防止 Eclipselink Moxy 转义元素内容

Question

我有以下类：

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "item", propOrder = {
    "content"
})
public class Item {
    @XmlElementRefs({
        @XmlElementRef(name = "ruleref", type = JAXBElement.class, required = false),
        @XmlElementRef(name = "tag", type = JAXBElement.class, required = false),
        @XmlElementRef(name = "one-of", type = JAXBElement.class, required = false),
        @XmlElementRef(name = "item", type = JAXBElement.class, required = false)
    })    
    @XmlMixed
    protected List<Serializable> content;

元素可以包含包含引号的字符串，例如：

<tag>"some kind of text"</tag>

此外，item 元素本身可以包含带引号的字符串：

<item>Some text, "this has string"</item>

使用 Moxy 时生成的 XML 会转义标签和项元素中的文本值：

<tag>&quote;some kind of text&quote;</tag>

我怎样才能防止它这样做，但仅限于这些元素？属性和其他元素应该保持不变（我的意思是转义）。

谢谢。

您可以通过

提供自己的CharacterEscapeHandler来覆盖默认字符转义。

import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement
public class Foo {
    private String bar;
    public String getBar() {
        return bar;
    }
    public void setBar(String bar) {
        this.bar = bar;
    }
}

演示

import java.io.*;
import javax.xml.bind.*;
import org.eclipse.persistence.jaxb.MarshallerProperties;
import org.eclipse.persistence.oxm.CharacterEscapeHandler;
public class Demo {
    public static void main(String[] args) throws Exception {
        JAXBContext jc = JAXBContext.newInstance(Foo.class);
        Foo foo = new Foo();
        foo.setBar(""Hello World"");
        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(foo, System.out);
        marshaller.setProperty(MarshallerProperties.CHARACTER_ESCAPE_HANDLER, new CharacterEscapeHandler() {
            @Override
            public void escape(char[] buffer, int start, int length,
                    boolean isAttributeValue, Writer out) throws IOException {
                out.write(buffer, start, length);
            }
        });
        marshaller.marshal(foo, System.out);
    }
}

输出

<?xml version="1.0" encoding="UTF-8"?>
<foo>
   <bar>&quot;Hello World&quot;</bar>
</foo>
<?xml version="1.0" encoding="UTF-8"?>
<foo>
   <bar>"Hello World"</bar>
</foo>
