具体代码如下
@At
@Ok("json")
@RequiresPermissions("hotword.manage.add")
@SLog(tag = "添加热门词汇", msg = "关键词:${args[1].getAttribute('hotwordName')}")
public Object add(@Param("hotwordName") String name,@Param("hotOrder") String hotOrder,HttpServletRequest req) {
try{
Api_hotWord fristWord = hotwordService.fetch(1);
if(fristWord==null){
fristWord=new Api_hotWord();
fristWord.setHid(1);
fristWord.setName(name);
fristWord.setHotOrder(Integer.parseInt(hotOrder));
fristWord.setCreteDate(new Date());
fristWord.setUpdateDate(new Date());
hotwordService.insert(fristWord);
}else {
fristWord.setName(name);
fristWord.setHotOrder(Integer.parseInt(hotOrder));
fristWord.setUpdateDate(new Date());
hotwordService.updateIgnoreNull(fristWord);
}
req.setAttribute("hotwordName", hotwordService.fetch(1).getName());
return Result.success("system.success");
} catch (Exception e) {
return Result.error("system.error");
}
}
}
```报的错如下

我感觉就是我的@SLog(tag = "添加热门词汇", msg = "关键词:${args[1].getAttribute('hotwordName')}")这个有问题,但是我并不会改

0、1、2,自己数下下标是几?。。

竟然是2,我之前一直在0和1哪里整,谢谢了

其实呢, 上下文里面多放个req和resp就没这样的烦恼了嘛
