xml – 如何使用JAXB抑制XSI

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<TEST2 xmlns="http://projects/open/2012/UniformProxySystem">
    <XXX1 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:nil="true"/>
    <XXX2>17:02:26</XXX2>
    <XXX3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:nil="true"/>
</TEST2>

但是我想要它如下：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<TEST2 xmlns="http://projects/open/2012/UniformProxySystem" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <XXX1 xsi:nil="true"/>
    <XXX2>17:01:08</XXX2>
    <XXX3 xsi:nil="true"/>
</TEST2>

寻找帮助,我正在使用JDK6和JAXB 2.1

package-info.java

@XmlSchema(
    elementFormDefault=XmlNsForm.QUALIFIED,
    namespace="http://projects/open/2012/UniformProxySystem",
    xmlns={@XmlNs(prefix="xsi",
                  namespaceURI="http://www.w3.org/2001/XMLSchema-instance")}
)
package com.example;

import javax.xml.bind.annotation.XmlNs;
import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;
