freemarker报错，本身就是String类型的字符串

FreeMarker template error:
For "${...}" content: Expected a string or something automatically convertible to string (number, date or boolean), or "template output" , but this has evaluated to a method+sequence (wrapper: f.e.b.SimpleMethodModel):
==> t.getTime [in template "views/tempweather.ftl" at line 155, column 47]

Tip: Maybe using obj.something instead of obj.getSomething will yield the desired value.

FTL stack trace ("~" means nesting-related):
- Failed at: ${t.getTime} [in template "views/tempweather.ftl" at line 155, column 45]

Java stack trace (for programmers):
