当前使用版本(必须填写清楚，否则不予处理)
3.3.0
该问题是怎么引起的？(最新版上已修复的会直接close掉)
重现步骤
- 代码生成的时候，设置生成kotlin类
gc.isKotlin = true - 生成字段常量：
strategy.isEntityColumnConstant=true - 使用Freemarkder模板引擎
mpg.templateEngine = FreemarkerTemplateEngine()

使用快照版本的xml，在生成mapper的时候也报错了：
一月 08, 2020 10:21:50 上午 freemarker.log._JULLoggerFactory$JULLogger error
严重: Error executing FreeMarker template
FreeMarker template error:
Can't convert boolean to string automatically, because the "boolean_format" setting was "true,false", which is the legacy deprecated default, and we treat it as if no format was set. This is the default configuration; you should provide the format explicitly for each place where you print a boolean.
----
Tip: Write something like myBool?string('yes', 'no') to specify boolean formatting in place.
----
Tip: If you want "true"/"false" result as you are generating computer-language output (not for direct human consumption), then use "?c", like ${myBool?c}. (If you always generate computer-language output, then it's might be reasonable to set the "boolean_format" setting to "c" instead.)
----
Tip: If you need the same two values on most places, the programmers can set the "boolean_format" setting to something like "yes,no". However, then it will be easy to unwillingly format booleans like that.
