Question

我想从struts2中的多个动作类生成下面提到的xml文件。

我从我的Struts 2操作类执行多个下面提到的操作，并将它们添加到单个现有的xml文件中。

1）在xml文件中添加新闻
2）在xml文件中添加页脚信息
3）在xml文件中添加代理商信息。

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<agencylink>
    <agency>
        <title>Ministry of Games</title>
        <url>http://www.abc.gov.</url>
    </agency>

    <agencyNews>
        <date>22/Apr/2014</date>
        <news>How do I clear my web browsers cache, cookies, and history?</news>
    </agencyNews>
  <headerLogo>
    <img>images/header.jpg</img>
  </headerLogo>
  <footerText>
    <ftxt>All rights reserved.</ftxt>
  </footerText>
  <aLoginLogo>
    <img>images/logo1.jpg</img>
  </aLoginLogo>
  <aHeaderLogo>
    <img>images/logo2.jpg</img>
  </aHeaderLogo>

  </agencylink>

我正在使用JaxB。当我执行这个不同的不同操作时，我的xml文件附加了该信息，但是当它存储在xml文件中时，标签名称是相同的。

标记名称必须与上面提到的xml文件类似。

当我更新新闻信息时，所有标签名称都更改为<agencyNews>。

所以请任何人帮我通过JaxB获取这个xml格式。

下面是我的Java代码

    package com.ocr.nsw.xml;

    import java.util.List;

    import javax.xml.bind.annotation.XmlAccessType;
    import javax.xml.bind.annotation.XmlAccessorType;
    import javax.xml.bind.annotation.XmlElement;
    import javax.xml.bind.annotation.XmlElementWrapper;
    import javax.xml.bind.annotation.XmlRootElement;
    import javax.xml.bind.annotation.XmlSeeAlso;

    @XmlRootElement(name = "agencylink")
    @XmlAccessorType(XmlAccessType.FIELD)
    @XmlSeeAlso({ Agency.class, AgencyNews.class, HeaderLogo.class,
            FooterText.class, ALoginLogo.class, AHeaderLogo.class })
    public class AgencyLink {

        @XmlElement(name = "agencyNews")
        private List<AgencyNews> adate;

        @XmlElement(name = "agencyNews")
        private List<AgencyNews> anews;

        @XmlElement(name = "agency")
        private List<Agency> atitle;

        @XmlElement(name = "agency")
        private List<Agency> aurl;

        @XmlElement(name = "footerText")
        private List<FooterText> aftxt;

        @XmlElement(name = "headerLogo")
        private List<HeaderLogo> headerLogoImg;

        @XmlElement(name = "aLoginLogo")
        private List<ALoginLogo> loginLogoImg;

        @XmlElement(name = "aHeaderLogo")
        private List<AHeaderLogo> aHeaderLogoImg;
    }

_____

public static void xmlWrite(List list, String filePath) {

    AgencyLink agencyLink = new AgencyLink();
    agencyLink.setAurl(null);
    agencyLink.setAnews(list);
    agencyLink.setAtitle(null);
    agencyLink.setAftxt(null);
    agencyLink.setHeaderLogoImg(null);
    agencyLink.setLoginLogoImg(null);
    agencyLink.setaHeaderLogoImg(null);

    if (marshalling(filePath, agencyLink)) {
        System.out.println("Success");
    }
}

------

@SuppressWarnings("rawtypes")
public static Object unMarshalling(String filePath, Class clazz) {
    try {
        File file = new File(filePath);
        JAXBContext jaxbContext = JAXBContext.newInstance(clazz);
        Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
        Object obj = clazz.cast(jaxbUnmarshaller.unmarshal(file));
        return obj;
    } catch (JAXBException e) {
        e.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    }

    return null;
}

从这段代码中我得到了下面提到的XML文件

<?xml version="1.0" encoding="ISO-8859-1" standalone="yes"?>
<agencylink>
    <agencyNews xsi:type="agency" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
        <title>Ministry of Health</title>
        <url>http://www.abc.gov.bn</url>
    </agencyNews>
    <agencyNews>
        <date>22/Apr/2014</date>
        <news>How do I clear my web browsers cache, cookies, and history?</news>
    </agencyNews>
    <agencyNews>
        <date>20/10/2013</date>
        <news>10</news>
    </agencyNews>
    <agencyNews xsi:type="headerLogo" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
        <img>images/header.jpg</img>
    </agencyNews>
    <agencyNews xsi:type="footerText" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
        <ftxt>All rights reserved</ftxt>
    </agencyNews>
    <agencyNews xsi:type="aLoginLogo" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
        <img>images/logo1.jpg</img>
    </agencyNews>
    <agencyNews xsi:type="aHeaderLogo" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
        <img>images/logo2.jpg</img>
    </agencyNews>
</agencylink>
