如何在Java中创建JAXBXML数组类型？

我正在构建一个API，并且我已经尝试与Postman一起创建一个新的“

项目

”，并且只接受“

项目

”，如下所示：

我的输出没有我想要的

type=“array”

。我想知道如何在java ou jaxb中手动或不将

type=“array”

设置为我的输出（这是打印xml输出的代码部分

jaxbMarshaller.marshall（invoiceRec，System.out）；

）

所以这是我的输出现在是这样，我的目标是：

<items>
        <item>
            <id>1162842</id>
            <name>tatat2</name>
            <description>1</description>
            <unit_price>1.0</unit_price>
            <unit>hour</unit>
        </item>
        <item>
            <id>1163631</id>
            <name>testItem2333</name>
            <description>abc</description>
            <unit_price>1.0</unit_price>
            <unit>hour</unit>
        </item>
    </items>

它给我的是带有

的输出，不带

数组的字段，如下所示：

<items type="array">
        <item>
            <id>1162842</id>
            <name>tatat2</name>
            <description>1</description>
            <unit_price>1.0</unit_price>
            <unit>hour</unit>
        </item>
        <item>
            <id>1163631</id>
            <name>testItem2333</name>
            <description>abc</description>
            <unit_price>1.0</unit_price>
            <unit>hour</unit>
        </item>
</items>

<items type="array">
        <item>
            <id>1162842</id>
            <name>tatat2</name>
            <description>1</description>
            <unit_price>1.0</unit_price>
            <unit>hour</unit>
        </item>
        <item>
            <id>1163631</id>
            <name>testItem2333</name>
            <description>abc</description>
            <unit_price>1.0</unit_price>
            <unit>hour</unit>
        </item>
</items>
