java:写入xml文件 [英] java: write to xml file

问题描述

在java中我需要创建如下所示的xml文件:

in java I need to create xml file which look like this:

<?xml version="1.0" encoding="UTF-8"?>
<NikuDataBus xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../xsd/nikuxog_customObjectInstance.xsd">
    <Header action="write" externalSource="NIKU" objectType="customObjectInstance" version="8.1.0.4247"/>
    <customObjectInstances objectCode="hen_allockey_p">
        <instance instanceCode="MIG5033028" objectCode="hen_allockey_p"
        parentInstanceCode="001260" parentObjectCode="project">
            <CustomInformation>
                <ColumnValue name="hen_from">200801</ColumnValue>
                <ColumnValue name="name">MIG5033028</ColumnValue>
                <ColumnValue name="code">MIG5033028</ColumnValue>
            <OBSAssocs/>
            <Security/>
        </instance>
    </customObjectInstances>
</NikuDataBus>

我在谷歌上找到了一些东西，但它不符合我的需求.由于我是 Java 新手，我不知道如何使其适应我的需求.

I found something on google, but it didn't match to my needs. And as I am new with java, I don't know how to adapt it to my needs.

感谢您的帮助.

推荐答案

我是这样解决的.看起来很糟糕的代码，但它对我有用，也许是复制和粘贴导致的一些错误

I resolved it like this. It is bad looking code, but it works for me, maybe there are some errors caused by copy and paste

public class POIExcelReader {

private void setHenAllocKeyHeader(StringBuilder sb) {
    sb.append ("<?xml version=\"1.0\" encoding=\"UTF-8\"?>\r\n"
            + "<NikuDataBus xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xsi:noNamespaceSchemaLocation=\"../xsd/nikuxog_customObjectInstance.xsd\">\r\n"
            + "<Header action=\"write\" externalSource=\"NIKU\"objectType=\"customObjectInstance\" version=\"8.1.0.4247\"/>\r\n"
            + "<customObjectInstances objectCode=\"hen_allockey_p\">\r\n"
            + "<instance instanceCode=\"MIG5033028\" objectCode=\"hen_allockey_p\" parentInstanceCode=\"001260\" parentObjectCode=\"project\">\r\n");
}

private void setHenAllocKeyBottom (StringBuilder sb) {
    sb.append ("<OBSAssocs/>\r\n"
            +"<Security/>\r\n"
            +"</customObjectInstances>\r\n" 
            + "</NikuDataBus>\r\n");
}

protected void jobRun() throws Exception {

    StringBuilder sb = new StringBuilder();
    setHenAllocKeyHeader(sb);
    String prolog = sb.toString();

    sb = new StringBuilder();
    setHenAllocKeyBottom(sb);
    String epilog = sb.toString();


    FileOutputStream fos = new FileOutputStream("c:\\test\\osem.xml");
    OutputStreamWriter osw = new OutputStreamWriter(fos, Charset.forName("UTF-8"));
    osw.write(prolog);
    osw.write(epilog);
    osw.flush();
    osw.close();

}
public static void main(String[] args){
try{
            job.jobRun();
    } catch (Exception e)
    {
        System.out.println("");
    }
}
