2. Establish routing
package com.csj2018.o2o.web.frontend;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
@RequestMapping(value="/frontend")
public class FrontendController {
@RequestMapping(value="/index",method=RequestMethod.GET)
private String index() {
return "frontend/index";
}
@RequestMapping(value="/shoplist",method=RequestMethod.GET)
private String shopShopList() {
return "frontend/shoplist";
}
}
3. Verify the front end
