Slf4j print abnormal stack information

SLF4J 1.6.0 The previous version

Only in this way can the error stack be printed

logger.error(String msg, Throwable t);------>logger.error(e.getMessage(),e); 
 perhaps 
logger.info(String msg, Throwable t);------>logger.info(e.getMessage(),e); 

    @GetMapping("/test")
    public String test(){
    
        try {
    
           int i = 1/0;
        } catch (Exception e) {
    
            log.error("  Abnormal information ", e);
        }
    }

therefore SLF4J 1.6.0 The previous version It's usually used String.format Method formatting msg.

SLF4J 1.6.0 After the version ,

error(String format, Object... arguments)　
info(String format, Object... arguments)　

Normal writing will also print exception stack information , It's just a rule Throwable Object must be the last parameter ． If you don't follow this rule , Exception stack information will not be printed .
Be careful e Unwanted {}, If it is added in front, the stack information will not be printed

Write like this ：

 log.error("  Abnormal information t:{},id:{}.", e.getMessage(),"1234567", e);

You can't write it like that ：

 log.error("  Abnormal information t:{},id:{}, e:{}", e.getMessage(),"1234567", e);

 @GetMapping("/test")
    public String test(){
    
   
        try {
    
           int i = 1/0;
        } catch (Exception e) {
    
            log.error("  Abnormal information t:{},id:{}.", e.getMessage(),"1234567", e);
        }

        return "=========get test success!========";
    }

The following methods will not print stack information

log.error(" Abnormal information getStackTrace:{}“, e.getStackTrace());
log.error(” Abnormal information toString:{}", e.toString());
