1、搭建Security的環境，新增pom,xml相關依賴

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</
 
groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
 

        </dependency>

2、新增靜態資原始檔和頁面

3、配置application.yml

spring:
  thymeleaf:
    cache: false

4、測試頁面跳轉的IndexController類

@Controller
public class IndexController {

    @RequestMapping({"/","/index"})
    public String index(){
        return "index";
    }

    @RequestMapping(value = "/toLogin")
    public String toLogin() {
        return "views/login";
    }

    @RequestMapping(value = "/level1/{id}")
    public String level1(@PathVariable("id") Integer id) {
        return "views/level1/" + id;
    }

    @RequestMapping(value = "/level2/{id}")
    public String level2(@PathVariable("id") Integer id) {
        return "views/level2/" + id;
    }

    @RequestMapping(value = "/level3/{id}")
    public String level3(@PathVariable("id") Integer id) {
        return "views/level3/" + id;
    }
}
