SpringBoot简单使用Security

1.pom文件

<dependencies>
        <!--添加方言-->
        <dependency>
            <groupId>org.thymeleaf.extras</groupId>
            <artifactId>thymeleaf-extras-springsecurity5</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>

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

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

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
            <exclusions>
                <exclusion>
                    <groupId>org.junit.vintage</groupId>
                    <artifactId>junit-vintage-engine</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
    </dependencies>

2.SpringBoot启动类

/**
 * 1、引入SpringSecurity；
 * 2、编写SpringSecurity的配置类；
 *         @EnableWebSecurity   extends WebSecurityConfigurerAdapter
 * 3、控制请求的访问权限：
 *         configure(HttpSecurity http) {
 *              http.authorizeRequests().antMatchers("/").permitAll()
 *                  .antMatchers("/level1/**").hasRole("VIP1")
 *         }
 * 4、定义认证规则：
 *         configure(AuthenticationManagerBuilder auth){
 *              auth.inMemoryAuthentication()
 *                  .withUser("zhangsan").password("123456").roles("VIP1","VIP2")
 *         }
 * 5、开启自动配置的登陆功能：
 *         configure(HttpSecurity http){
 *              http.formLogin();
 *         }
 * 6、注销：http.logout();
 * 7、记住我：Remeberme()；

@SpringBootApplication
public class SpringbootSecurityApplication {

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

3.Security配置类

@EnableWebSecurity
public class MySecurityConfig extends WebSecurityConfigurerAdapter {

    @Bean
    public UserDetailsService userDetailsService() {
        InMemoryUserDetailsManager manager = new InMemoryUserDetailsManager();
        manager.createUser(User.withDefaultPasswordEncoder().username("zhangsan").password("password").roles("VIP1").build());
        manager.createUser(User.withDefaultPasswordEncoder().username("amao").password("password").roles("VIP2").build());
        manager.createUser(User.withDefaultPasswordEncoder().username("lisi").password("password").roles("VIP3").build());
        return manager;
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        //super.configure(http);
        //定制请求的授权规则
        http.authorizeRequests().antMatchers("/").permitAll()
             .antMatchers("/level1/**").hasRole("VIP1")
             .antMatchers("/level2/**").hasRole("VIP2")
             .antMatchers("/level3/**").hasRole("VIP3");
        //开启自动配置的登陆功能，效果，如果没有登陆，没有权限就会来到登陆页面
        //BCryptPasswordEncoder encoder = new BCryptPasswordEncoder();
        http.formLogin().usernameParameter("user").passwordParameter("pwd");
                /*.loginPage("/userlogin")*/
        //1、/login来到登陆页
        //2、重定向到/login?error表示登陆失败
        //3、更多详细规定
        //4、默认post形式的 /login代表处理登陆
        //5、一但定制loginPage；那么 loginPage的post请求就是登陆

        //开启自动配置的注销功能。
        http.logout().logoutSuccessUrl("/");//注销成功以后来到首页
        //1、访问 /logout 表示用户注销，清空session
        //2、注销成功会返回 /login?logout 页面；

        //开启记住我功能
        http.rememberMe().rememberMeParameter("remeber-me");
        //登陆成功以后，将cookie发给浏览器保存，以后访问页面带上这个cookie，只要通过检查就可以免登录
        //点击注销会删除cookie

    }

    //定义认证规则
//    @Override
//    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
//        auth.inMemoryAuthentication()
//                .withUser("zhangsan").password("123456").roles("VIP1","VIP2")
//                .and()
//                .withUser("lisi").password("123456").roles("VIP2","VIP3")
//                .and()
//                .withUser("wangwu").password("123456").roles("VIP1","VIP3");
//    }
}

4.控制器

@Controller
public class KungfuController {
    private final String PREFIX = "pages/";
    /**
     * 欢迎页
     * @return
     */
    @GetMapping("/")
    public String index() {
        return "welcome";
    }
    
    /**
     * 登陆页
     * @return
     */
    @GetMapping("/userlogin")
    public String loginPage() {
        return PREFIX+"login";
    }
    
    /**
     * level1页面映射
     * @param path
     * @return
     */
    @GetMapping("/level1/{path}")
    public String level1(@PathVariable("path")String path) {
        return PREFIX+"level1/"+path;
    }
    
    /**
     * level2页面映射
     * @param path
     * @return
     */
    @GetMapping("/level2/{path}")
    public String level2(@PathVariable("path")String path) {
        return PREFIX+"level2/"+path;
    }
   
    /**
     * level3页面映射
     * @param path
     * @return
     */
    @GetMapping("/level3/{path}")
    public String level3(@PathVariable("path")String path) {
        return PREFIX+"level3/"+path;
    }
}

6.关闭Thymeleaf的缓存

# 使用html模板
spring.thymeleaf.mode=HTML
# 编译缓存，开发环境写false，更新页面可马上看到效果；生产环境用true，速度快一些，但更新页面后需重启应用才能看到效果
spring.thymeleaf.cache=false
