I am learning Spring MVC using Maven project and I facing a problem. This is my controller:
@Controller
public class HelloWorldController {
@RequestMapping("/hello")
public String hello(Model model) {
model.addAttribute("greeting", "Hello Spring MVC");
return "helloworld";
}
}
I run my project by this way (I am using Eclip Neon): Right click on project > Run as > Run configurations > Right click on Maven Build > New > Enter name, base directory and goals > Apply > Run. Done.
When I access this url
the "helloworld"
page will be displayed, this is simple.
Now I want to change @RequestMapping("/hello")
to @RequestMapping("/hello1")
, like this
@Controller
public class HelloWorldController {
@RequestMapping("/hello1")
public String hello(Model model) {
model.addAttribute("greeting", "Hello Spring MVC");
return "helloworld";
}
}
I run my project again, access this url and I got error " The requested resource is not available."
I try to access this and "helloworld"
still be displayed
I open Task manager and I figure out that the "javaw.exe"
create a new instance every time I run my project, but the older version is always get affect. I try to kill all "javaw.exe"
processes by hand, run the project again and it works.
So the question is, how to kill old "javaw.exe"
process everytime I run my project??? Or maybe I build or run Maven project wrong way?
RESOLVED: I realize I can run a maven project follow the normal way (By tomcat), then the problem resolved. Thank you all.
Instead of running a second time, you probably want to redeploy your running code. See https://www.mkyong.com/eclipse/how-to-configure-hot-deploy-in-eclipse/
