Question

freemarker.core.NonSequenceOrCollectionException: The value you try to list is an extended_hash+string (com.nari.guangzhou.fsauto.entity.InspectionItem wrapped into f.e.b.StringModel), thus you must specify two loop variables after the "as"; one for the key, and another for the value, like <#... as k, v>).

Java to Word. use freemarker,failed 100 times,i am crazy...
