问题 I'm using dependency injection to access my services when needed but i'm now wanting to create a concurrent task but this is causing issues due to dependency injected objects and their lifetimes. I've read this article (Heading: Prevents multi-threading): Link And from that, I've gathered that this isn't possible. My objective is to let the client send a request to begin a job that could take longer than the connection timeout of the client, thus I want to have an endpoint that initiates a

问题 I am using sprin version 4.3.8.RELEASE. also i am using @Value to inject values from property file, if the properties are string that no problem, but if the property is Integer that is a problem (i know there is many questions about this i tried all the answers but the issue still exist) The property is CONNECTION.TIME.OUT=100000 First solution @Value("${CONNECTION.TIME.OUT}") protected Integer connectionTimeOut; Ecxeption Failed to convert value of type 'java.lang.String' to required type
