      {
         "id": "1",
         "unitname": "unit1",
         "eventId": "2",
         "transactiontype": "1"
      },
      {
         "id": "2",
         "unitname": "unit2",
         "eventId": "2",
         "transactiontype": "1"
      },
      {
         "id": "3",

Maybe you can use the json.org library. I'm not sure if this library does exactly what you want.

也许你可以使用json.org库。我不确定这个库是否完全符合您的要求。

You can use it like that:

你可以这样使用:

JSONObject json = new JSONObject(str);
String xml = XML.toString(json);

toString can take a second argument to provide the name of the XML root node.

toString可以使用第二个参数来提供XML根节点的名称。

XML to JSON using XML.toJSONObject(java.lang.String)

使用XML. tojsonobject (java.lang.String)从XML到JSON

POM

砰的一声

<dependency>
    <groupId>org.json</groupId>
    <artifactId>json</artifactId>
    <version>20170516</version>

Here is an XSLT 3.0 solution.

这里是一个XSLT 3.0解决方案。

<xsl:transform version="3.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template name="main">
  <xsl:variable name="in" select="json-doc('input.json')" as="map(*)"/>
  <Units userId="{$in?userId}">
    <xsl:for-each select="$in?Unit?*"
      <Unit id="{?id}" unitname="{?unitname}" 
            eventId="{?eventId}"  transactiontype="{?transactiontype}"/>
    </xsl:for-each>
  </Units>
</xsl:template>

</xsl:transform>

You can run this from Java by installing Saxon-PE 9.7.

您可以通过安装Saxon-PE 9.7从Java运行它。
