java - if条件下的json查询

Question

{
 "class": "premnath",
 "forInitiatorOnly": true,
 "text": "#if($payload.isUploaded)  ${payload.getModuleRef().moduleName()} 
          completed successfully.
          Number of records processed were ${payload.getNoOfRecords()} and 
          if(${payload.getThin()} !=0)} 
          number of thins are ${payload.getThin()}  
          #end"
}

在 if 条件没有检查的情况下，我得到这样的输出

module is uploaded successfully. Number of records:9 and (2!=0) number of thins:9

您能告诉我如何检查状况吗？

Answer 1

if(${payload.getThin()} !=0)}

最后一个 } 不应该在那里，不是吗？
