SpringBoot 方法拦截器记录日志 RequestContextHolder 为NULL

今天遇到一个奇怪的问题，以前SSM框架迁移过来的日记记录类中出现一个错误

Error creating bean with name 'requestMappingHandlerMapping' defined in class path resource

完整源码如下：

sysLog.setParams(bfParams.toString());

sysLog.setIp(request.getRemoteAddr());

}

}

}catch(Exceptione) {

logger.error(e.getMessage(),e);

}

}

returnpoint.proceed();

}

String[]pattern= {"index","manager","dataGrid","add","addpage","edit","editpage","delete","grant"};

for(String s:pattern) {

if(method.indexOf(s) > -1) {

return true;

}

}

return false;

}

}
 

报错说：RequestContextHolder为空

原因出现在这里，

@Pointcut(value="execution(* cn.fy3d.boot.*.*..*(..))")

本类LogAdvice是通过@Aspect实现的方法拦截器，上面的切面规则，会拦截所有方法，而RequestContextHolder是springmvc中的上下文的Request容器,只会在controller中存在，其他方法中肯定是null、

解决办法：修改切面规则，定位到controller

    @Pointcut(value = "execution(* cn.fy3d.boot.*.*.*Controller.*(..))")
