【问题描述】：
我正在尝试使用 JAXB 进行编组。
我的输出是这样的：
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<root>
<name><![CDATA[<h1>kshitij</h1>]]></name>
<surname><h1>solanki</h1></surname>
<id><h1>1</h1></id>
</root>
...但我需要这样的输出：
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<root>
<name><![CDATA[<h1>kshitij</h1>]]></name>
<surname><![CDATA[<h1>solanki</h1>]]></surname>
<id><![CDATA[0]]></id>
</root>
我正在使用以下代码来执行此操作。
如果我取消注释代码，我会得到 PropertyBindingException。没有它我可以编译，但我没有得到所需的确切输出。
package com.ksh.templates;
import java.io.IOException;
import java.io.StringWriter;
import java.io.Writer;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;
import com.sun.xml.bind.marshaller.CharacterEscapeHandler;
public class MainCDATA {
public static void main(String args[])
{
try
{
String name = "<h1>kshitij</h1>";
String surname = "<h1>solanki</h1>";
String id = "<h1>1</h1>";
TestingCDATA cdata = new TestingCDATA();
cdata.setId(id);
cdata.setName(name);
cdata.setSurname(surname);
JAXBContext jaxbContext = JAXBContext.newInstance(TestingCDATA.class);
Marshaller marshaller = jaxbContext.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
marshaller.setProperty(CharacterEscapeHandler.class.getName(), new CharacterEscapeHandler() {
public void escape(char[] ac, int i, int j, boolean flag,
Writer writer) throws IOException {
writer.write( ac, i, j ); }
});
StringWriter stringWriter = new StringWriter();
marshaller.marshal(cdata, stringWriter);
System.out.println(stringWriter.toString());
} catch (Exception e) {
System.out.println(e);
}
}
}
我的 bean 看起来像这样：
package com.ksh.templates;
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.adapters.XmlJavaTypeAdapter;
import com.sun.xml.txw2.annotation.XmlCDATA;
@XmlRootElement(name = "root")
@XmlAccessorType(XmlAccessType.FIELD)
public class TestingCDATA {
@XmlElement
@XmlJavaTypeAdapter(value = AdaptorCDATA.class)
private String name;
@XmlElement
@XmlJavaTypeAdapter(value = AdaptorCDATA.class)
private String surname;
@XmlCDATA
public String getName() {
return name;
}
@XmlCDATA
public void setName(String name) {
this.name = name;
}
@XmlCDATA
public String getSurname() {
return surname;
}
@XmlCDATA
public void setSurname(String surname) {
this.surname = surname;
}
}
适配器类
public class AdaptorCDATA extends XmlAdapter<String, String> {
@Override
public String marshal(String arg0) throws Exception {
return "<![CDATA[" + arg0 + "]]>";
}
@Override
public String unmarshal(String arg0) throws Exception {
return arg0;
}
}
