采购方式：FreeMarker template error (DEBUG mode; use RETHROW in production!):

The following has evaluated to null or missing:

==> htgg.buy_mode [in template "htgg.ftl" at line 250, column 20]

----

Tip: It's the step after the last dot that caused this error, not those before it.

----

Tip: If the failing expression is known to legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use when-presentwhen-missing. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??

----

----

FTL stack trace ("~" means nesting-related):

- Failed at: #if htgg.buy_mode == "zqyjgg" [in template "htgg.ftl" at line 250, column 15]
