XJC生成JAXB类,其中有太多来自XSD的变量

我在下面有一些非常基本的数据。我使用的工作流是从Google工作表导出到 xml

如何生成 JAXB 使用以下工具合理的类 trang 或 xmllint ,或者,如下所示, xjc

thufir@dur:~/jaxb$ 
thufir@dur:~/jaxb$ cat dummy.xml 
<data>
  <b />
  <c />
  <d />
  <e />
  <f />
  <f />
  <h />
  <i />
</data>

thufir@dur:~/jaxb$ 
thufir@dur:~/jaxb$ trang dummy.xml dummy.xsd
thufir@dur:~/jaxb$ 
thufir@dur:~/jaxb$ cat dummy.xsd 
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
  <xs:element name="data">
    <xs:complexType>
      <xs:sequence>
        <xs:element ref="b"/>
        <xs:element ref="c"/>
        <xs:element ref="d"/>
        <xs:element ref="e"/>
        <xs:element maxOccurs="unbounded" ref="f"/>
        <xs:element ref="h"/>
        <xs:element ref="i"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
  <xs:element name="b">
    <xs:complexType/>
  </xs:element>
  <xs:element name="c">
    <xs:complexType/>
  </xs:element>
  <xs:element name="d">
    <xs:complexType/>
  </xs:element>
  <xs:element name="e">
    <xs:complexType/>
  </xs:element>
  <xs:element name="f">
    <xs:complexType/>
  </xs:element>
  <xs:element name="h">
    <xs:complexType/>
  </xs:element>
  <xs:element name="i">
    <xs:complexType/>
  </xs:element>
</xs:schema>
thufir@dur:~/jaxb$ 

我可以创造 jaxb 文件为:

thufir@dur:~/jaxb$ 
thufir@dur:~/jaxb$ xjc dummy.xsd 
parsing a schema...

首先,有点垃圾。

是吗 有 对每个元素有不同的方法?太简单了 CSV 文件,但当它到达 Java .

哪种方法更明智?因为如果原始文件是一千行,那么我会不寒而栗地想到生成的Java类会是什么样子。

那么,我该如何修复 xsd
