**二 启动类**

package org.fkit.logintest;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    // @SpringBootApplication指定这是一个 spring boot的应用程序.
    @SpringBootApplication
    public class App {
        public static void main(String[] args) {
            // SpringApplication 用于从main方法启动Spring应用的类。
            SpringApplication.run(App.class, args);
        }
    }

**三 控制器**

1 IndexController

package org.fkit.logintest.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    // Controller注解用于指示该类是一个控制器
    @Controller
    public class IndexController {
        // 映射"/"请求
        @RequestMapping("/")
        public String index(Model model){
            System.out.println("IndexController index方法被调用......");
            // 根据Thymeleaf默认模板，将返回resources/templates/index.html
            return "index";
        }
    }

2 LoginController

package org.fkit.logintest.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.PostMapping;
    import org.springframework.web.bind.annotation.RequestParam;
    import org.springframework.web.servlet.ModelAndView;
    
    @Controller
    public class LoginController {
        
        @PostMapping("login")
        public ModelAndView login(
                @RequestParam("loginName") String loginName,
                @RequestParam("password") String password,
                ModelAndView mv){
            System.out.println("LoginController login方法被调用......");
            System.out.println("LoginController 登录名:"+loginName + " 密码:" + password);
            // 重定向到到main请求
            mv.setViewName("redirect:/main");
            return mv;
        }
    }

3 MainController

package org.fkit.logintest.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    @Controller
    public class MainController {
        @RequestMapping(value="/main")
        public String main(){
            System.out.println("MainController main方法被调用......");
            // 根据Thymeleaf默认模板，将返回resources/templates/main.html
            return "main";
        }
    }

**四 视图**

1 index.html
