java - 从 jaxb 生成正确的 xml

Question

我通过在 swing 表单 中获取用户的输入来生成 xml，现在我希望 xml 参数值应设置为用户输入的内容，例如用户输入以下值:参数...

route cna="trk"
 typ="e_pwap"
 ver="96"
 sk_cna="ltp6"
 sk_typ="55"
 sk_ver="26"
 prefilterfilename="sjj"
 prefiltertype="true"
 postfilterfilename=""
 postfiltertype=""
 xfm=""
 gelcatnumbersource="16"
 gelcatnumbersink="40" 

所以最终生成的 xml 应该是......

  <route cna="trk" typ="e_pwap" ver="96" sk_cna="ltp6" sk_typ="55" sk_ver="26" prefilterfilename="sjj" prefiltertype="true" postfilterfilename="" postfiltertype="" xfm="" gelcatnumbersource="16" gelcatnumbersink="40" /> 

现在即使用户输入值也不会发生，现在它正在打印为...

  <route cna="cnavalue" typ="typ" ver="ver" sk_cna="sk_cna" sk_typ="sk_typ" sk_ver="sk_ver" prefilterfilename="prefilterfilename" prefiltertype="prefiltertype" postfilterfilename="postfilterfilename" postfiltertype="postfiltertype" gelcatnumbersource="gelcatnumbersource" gelcatnumbersink="gelcatnumbersink"/>

请告知如何纠正此问题。下面是我的pojo..

Answer 1

嗯，将字段的值设置为“cnavalue”确实会导致 XML 包含属性 cnavalue="cnavalue"。

            Route route = new Route();
            route.setCna( "cnavalue" );

使用类似的东西

            route.setCna( textField_1.getText() );
