图片文件上传 异常处理

点击图片上传时出现以下报错:

redis.clients.jedis.exceptions.JedisException: Could not get a resource from the pool

严重: Servlet.service() for servlet [springmvc] in context with path [] threw exception [Request processing failed; nested exception is redis.clients.jedis.exceptions.JedisException:

Could not get a resource from the pool] with root cause
java.util.NoSuchElementException: Unable to validate object

注释了所有的bind 127.0.0.1 和改了protected-mode为no  导致redis启动不了

 

Caused by: redis.clients.jedis.exceptions.JedisConnectionException: java.net.ConnectException: Connection refused: connect

redis服务无法启动   https://blog.youkuaiyun.com/maxsky/article/details/79775118

解决方法 把这个注释打开了

 

上传成功运行log:
