java - 从 xml 生成 xsd 时混合 ="true"

Question

我正在尝试使用 intelliJ 从现有 XML 文件生成 XSD。但是生成的 xsd 有这个 - 'mixed = "true"' 属性，我不希望它出现，因为最终生成的类(使用 xjc)现在包含其成员作为我不想要的可序列化属性。有谁知道我该如何防止这种情况发生？

XML 文件 -

<?xml version="1.0" encoding="UTF-8"?>
<STEPS>
    <STEP>
        <taskId>1</taskId>
        <dependency>

        </dependency>
        <task>Sample Step</task>
        <techDetail>SVN Script path</techDetail>
        <description>Sample step</description>
        <comments>No commnets</comments>
    </STEP>
    <STEP>
        <taskId>2</taskId>
        <dependency>
            <dependanttaskId>1</dependanttaskId>
        </dependency>
        <task>Second Sample Step</task>
        <techDetail>SVN Script Path Again</techDetail>
        <description>Sample step 2</description>
        <comments>No comments again</comments>
    </STEP>
    <STEP>
        <taskId>3</taskId>
        <dependency>
            <dependanttaskId>1</dependanttaskId>
            <dependanttaskId>2</dependanttaskId>
        </dependency>
        <task>Third Sample Step</task>
        <techDetail>SVN Script Path Again</techDetail>
        <description>Sample step 3</description>
        <comments>No comments again 3</comments>
    </STEP>
</STEPS>

Answer 1

删除 <dependency>``</dependency> 中的空格并将其提及为 <dependency/>

• mixed=true 当需要在父级的子元素之间允许一些字符时出现，在这种情况下父级是 dependency 。所以我假设 dependency 中存在像空格这样的字符元素。
