springboot集成SpringSecurity
springboot实现SpringSecurity
1、先导入依赖
<dependency>
<groupId>org.thymeleaf.extras</groupId>
<artifactId>thymeleaf-extras-springsecurity5</artifactId>
<version>3.0.4.RELEASE</version>
</dependency>
<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.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
2、导入静态资源
3、关闭thymeleaf缓存
spring.thymeleaf.cache=false
4、编写controller层，控制页面跳转
@Controller
public class RouterController {
@RequestMapping({"/","/index"})
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;
}
}
5、编写SecurityConfig
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
//首页所有人都可以访问，特定功能只能由特定的人访问
// 请求授权的规则
http.authorizeHttpRequests()
.antMatchers("/").permitAll()
.antMatchers("/level1/**").hasRole("Vip1")
.antMatchers("/level2/**").hasRole("Vip2")
.antMatchers("/level3/**").hasRole("Vip3");
// 登录
// 没有权限默认去登录页
http.formLogin().loginPage("/toLogin").loginProcessingUrl("/login").defaultSuccessUrl("/index")
.usernameParameter("username").passwordParameter("password");
// 注销404
// 现版本可以不用写，默认关闭
// 关闭csrf功能 跨站请求伪造
http.csrf().disable();
// 注销
// 成功后跳首页
http.logout().logoutSuccessUrl("/");
// 开启记住我功能 cookie
http.rememberMe().rememberMeParameter("remember");
}
// 认证
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
// 一般从数据库中读
auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder())
.withUser("fan").password(new BCryptPasswordEncoder().encode("123")).roles("Vip2","Vip3")
.and()
.withUser("root").password(new BCryptPasswordEncoder().encode("123456")).roles("Vip1","Vip2","Vip3")
.and()
.withUser("abc").password(new BCryptPasswordEncoder().encode("123")).roles("Vip1");
}
}
6、定制化index.html
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org"
xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity5">
<head>
<meta charset="UTF-8">

7、测试
8、总结一下，在我跟着狂神学这个springSecurity时，WebSecurityConfigurerAdapter已经被弃用了，官方推荐用户转向基于组件的安全配置
