java+freemarker genera bucle de documento de Word objeto java Vue front-end descarga documento de Word

plantilla:

1.1 Preparar archivo de plantilla ftl o xml

1.2 Guarde como un archivo xml y luego edite el archivo xml y agregue el código de ciclo al archivo xml donde se requiere la posición del ciclo 

<#list fieldListMap as list> </#list> (filedListMap = javaEntity ; as=nombre de variable definido por usted mismo)

 

 He doblado sublimitext node++ aquí y puedo agregar etiquetas de ciclo 

 1.3 Puede almacenarse en formato ftl o xml, solo léalo aquí

 extremo posterior

2. El backend usa freemarker-2.3.30 para generar la importación de pom
