I have a jsp page called reports.jsp and I have displayed the links in the view for a user to click. How can I invoke Spring controller method by clicking on the link that will pass an argument.
You have to use @PathVariable
in order to do this. Example:
Jsp:
<a href="<c:url value="/test/${object.argument}" />" >hello</a>
Controller:
@RequestMapping(value = "/test/{argument}", method = RequestMethod.GET)
public String Controller(@PathVariable("argument") String argument) {
...
}
I have resolved the answer by creating a link:
<a href=".../test?argName=arg1" >hello</a>
Controller:
@RequestMapping(value = "/test", method = RequestMethod.GET, params = {"argName"})
public String Controller(@RequestParam(value="argName", required = true, defaultValue = null) String argName) {
...
//Now do exciting things with variable argName
}
On the JSP page
<a class="opcion" href="<%= request.getContextPath()%>/inicio">Inicio</a>
And in the controller part backend
@Controller
public class HomeController {
@RequestMapping(value = "/inicio", method = RequestMethod.GET)
public String index(ModelMap model){
model.addAttribute("message", "cargaGeneracion");
return "index";
}
}
