SpringBoot: server.tomcat.connection-timeout NOT WORKING-CodePudding

I need to Timeout the request if no response is received in 5s. I tried server.tomcat.connection-timeout, but No Luck.

I am aware of spring.mvc.async.request-timeout property using Callable<?>, but server.tomcat.connection-timeout should work ,right?

application.properties

server.tomcat.connection-timeout=5s

Rest Controller

@PostMapping("/getdata")
public String call() throws Exception {

    Thread.sleep(10000);

    return "Hello";

}

CodePudding user response：

There is no setting in Spring MVC to control the timeout of request handled by Controller unless of-course you are using Async processing which basically means you need to return a Callable<> if you want spring.mvc.async.request-timeout to work. The property you are mentioning server.tomcat.connection-timeout is actually a tomcat property ( which is set up by Spring Boot) which basically refers to timeout if the client opens a connection but is not sending or it's very slow to send the request ( uri, headers etc. as per http protocol)

The number of milliseconds this Connector will wait, after accepting a connection, for the request URI line to be presented. Use a value of -1 to indicate no (i.e. infinite) timeout.

You can check this for an issue reported in Spring Boot and the comments by Spring team.
