Spring MVC
CacheControl, is a builder for creating "Cache-Control" HTTP response headers. It provides various methods supporting Cache-Control directives e.g. maxAge(..), mustRevalidate(), noCache(), cachePublic(), cachePrivate(), etc.
 package com.logicbig.example;
import org.springframework.http.CacheControl;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import javax.servlet.http.HttpServletResponse;
import java.time.LocalDateTime;
import java.util.concurrent.TimeUnit;
@Controller
public class TheController {
@RequestMapping(value = "/test1")
public String handle1 (HttpServletResponse response) {
String headerValue = CacheControl.maxAge(10, TimeUnit.SECONDS)
.getHeaderValue();
response.addHeader("Cache-Control", headerValue);
return "myView";
}
@ResponseBody
@RequestMapping(value = "/test2")
public ResponseEntity<String> handle2 () {
CacheControl cacheControl = CacheControl.maxAge(10, TimeUnit.SECONDS);
String testBody = "<p>Response time: " + LocalDateTime.now() +
"</p><a href=''>test2</a>";
return ResponseEntity.ok()
.cacheControl(cacheControl)
.body(testBody);
}
}
