• 启动类

@SpringBootApplication
public class WebApplication {
 
    public static void main(String[] args) {
        SpringApplication.run(WebApplication.class, args);
    }
 
}

• 测试接口

@Controller
public class TestController {
 
    // 需要认证才能访问的路径
    @RequestMapping({"/index", "/", ""})
    @ResponseBody
    public String index() {
        return "index";
    }
 
    // 不需要认证就能访问的路径
    @RequestMapping("/test")
    @ResponseBody
    public String test() {
        return "test";
    }
 
    // 认证成功后跳转的路径
    @GetMapping("/success")
    @ResponseBody
    public String success(){
        return "success";
    }
 
}

• 未认证时，直接访问test接口，访问成功
  

• 未认证时，直接访问index接口，跳转到认证页面
  

• 输入用户名和密码，跳转到index
