springboot_springSecurity整合

SpringSecurity

简介
SpringSecurity是针对Spring项目的安全框架,也是Spring Boot底层安全模块默认的技术选型,他可以实现强大的Web
安全控制,对于安全控制,我们仅仅需要引入spring-boot-starter-security模块,进行少量的配置,即可实现强大的安全管理!

重要的类:

  • WebSecurityConfigurerAdapter:自定义Security策略
  • AuthenticationManagerBuilder:自定义认证策略模式
  • EnableWebSecurity:开启WebSecurity模式

SpringSecurity的主要两个目标是“认证”和“授权”(控制访问)
“认证”:Authentication
“授权”:Authorization

案例实现

  • 1.导入依赖
<!--springboot-SpringSecurity-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>
  • 2.导入静态资源目录(不关键,可以自定义)
    image

  • 创建controller,页面跳转的路由

@Controller
public class RouterController {
    @RequestMapping({"/","/index","/index.html"})
    public String index(){
        return "index";
    }
    @RequestMapping("/toLogin")
    public String toLogin(){
        return "views/login";
    }
    @RequestMapping("/level1/{id}")
    public String level1(@PathVariable("id")int id){
        return "views/level1/"+id;
    }
    @RequestMapping("/level2/{id}")
    public String level2(@PathVariable("id")int id){
        return "views/level2/"+id;
    }
    @RequestMapping("/level3/{id}")
    public String level3(@PathVariable("id")int id){
        return "views/level3/"+id;
    }
}
  • 3.创建config(自定义SecurityConfig继承WebSecurityConfigurerAdapter)
//开启WebSecurity功能
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        //首页所有人可以访问,功能也只有对应权限的人可以访问
        //请求授权的规则
        http.authorizeRequests()
                .antMatchers("/").permitAll()   //首页所有用户都可以访问
                .antMatchers("/level1/**").hasRole("vip1")      //对应用户对用的授权页面
                .antMatchers("/level2/**").hasRole("vip2")
                .antMatchers("/level3/**").hasRole("vip3");
    }
}

  • 4.添加认证
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {

        //首页所有人可以访问,功能也只有对应权限的人可以访问
        //请求授权的规则
        http.authorizeRequests()
                .antMatchers("/").permitAll()
                .antMatchers("/level1/**").hasRole("vip1")
                .antMatchers("/level2/**").hasRole("vip2")
                .antMatchers("/level3/**").hasRole("vip3");
        //没有权限会到登录页面,需要开启登录的页面
        //Login
        http.formLogin();

        //防止网站攻击:get ,post
        http.csrf().disable();//关闭csrf(跨站请求伪造)功能,登出失败的可能原因

        //注销,开启注销功能
        http.logout().logoutSuccessUrl("/");
    }

    //认证
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder())
                .withUser("dingjie").password(new BCryptPasswordEncoder().encode("123456")).roles("vip2","vip3")
                .and()
                .withUser("root").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1","vip2","vip3")
                .and()
                .withUser("guest").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1");
    }
}

SpringSecurity自带的登录

  • html前端,security和thymeleaf整合

依赖:

<!--security整合thymeleaf-->
<dependency>
    <groupId>org.thymeleaf.extras</groupId>
    <artifactId>thymeleaf-extras-springsecurity5</artifactId>
    <version>3.0.4.RELEASE</version>

<!--xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4"获取提示-->
<html lang="en" xmlns:th="http://www.thymeleaf.org"
      xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4">
<!--登录注销-->
<div class="right menu">

......
//认证
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder())
            .withUser("dingjie").password(new BCryptPasswordEncoder().encode("123456")).roles("vip2","vip3")
            .and()
            .withUser("root").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1","vip2","vip3")
            .and()

}

不同用户显示不同的页面

guest游客界面:

登录页面的记住我功能

  • 首页页面添加
<div class="field">
    <input type="checkbox" name="remember"/>记住我
</div>
  • 在SecurityConfig定制登录的页面
//没有权限会到登录页面,需要开启登录的页面
//Login
//定制登录页
http.formLogin().loginPage("/toLogin")
        .usernameParameter("username")
        .passwordParameter("password")
        .loginProcessingUrl("/login");
  • 在SecurityConfig中添加remember-me功能
//开启记住我功能   cookie, 默认,自定义接收前端的参数
http.rememberMe().rememberMeParameter("remember");
