在templates文件夹里创建index页面
后端接口代码

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class controller {
@ResponseBody
@PostMapping ("/user/index")
public String index(String username,String password ) {
System.out.println(username+"******客户连接数****"+password);
return "cg";
}
@GetMapping("/login")
public String login() {
System.out.println("******客户连接数****");
return "login";
}
@GetMapping("/index")
public String index() {
System.out.println("******客户连接数****");
return "index";
}
}
