Question

当我导航/ app / wb / create时，我将进入下面的控制器方法，该方法需要调用流“/ app / main”，但是春天将其恢复为“/main.xhtml”。我的问题是如何从弹簧控制器重定向到流量？

@Controller
@RequestMapping("/wb")
public class HomeController {

    private static final Logger logger = LoggerFactory.getLogger(HomeController.class);

    /**
     * Simply selects the home view to render by returning its name.
     */

        @RequestMapping("/create/")
        public String home(Device device, Model model) {
            if (device == null) {
                logger.info("no device detected");
            } else if (device.isNormal()) {
                logger.info("Device is normal");
            } else if (device.isMobile()) {
                logger.info("Device is mobile");
            } else if (device.isTablet()) {
                logger.info("Device is tablet");
            }
            return "app/main"; // Where main is the flow id
        }
}

流量

        <transition on="newUser" to="signUp" />
    </view-state>

    <view-state id="signUp" view="signUp.xhtml" model="user">
        <transition on="backToSignIn" to="welcome" />
    </view-state>
</flow>

Answer 1

return "/main";

您必须删除应用程序路径

Answer 2

return "redirect:/main.xhtml"

你必须告诉控制器重定向。
