How do you set cache headers in Spring MVC?

Question

In an annotation-based Spring MVC controller, what is the preferred way to set cache headers for a specific path?

Answer 1

The answer is quite simple:

@Controller
public class EmployeeController {

    @RequestMapping(value = "/find/employer/{employerId}", method = RequestMethod.GET)
    public List getEmployees(@PathVariable("employerId") Long employerId, final HttpServletResponse response) {
        response.setHeader("Cache-Control", "no-cache");
        return employeeService.findEmployeesForEmployer(employerId);
    }

}

Code above shows exactly what you want to achive. You have to do two things. Add "final HttpServletResponse response" as your parameter. And then set header Cache-Control to no-cache.
