本文以及接下来有关spring security 的文章, 基于Spring Boot 2.1.0 RELEASE , Spring Security 5.1.2RELEASEjava
Spring Security是当今很是流行的,基于Spring提供了一套Web安全性的完整框架。用于对用户进行认证(Authentication)和受权(Authorization)。在用户认证方面,Spring Security 支持主流的验证方式,包括,HttpBasic认证,Http表单认证,Http摘要认证,OpenId以及LDAP(轻量目录访问协议:Lightweight Directory Access Protocol)等。在用户受权方面,Spring Security 提供了基于角色的访问控制和访问控制列表(Access Control List,ACL),能够对应用中的领域对象进行细粒度的控制。 本文将经过介绍如何在Spring Boot项目中使用Spring Security保护应用,咱们先讨论如何自定义用户的认证逻辑,经过Spring Security 提供的UserDetailService,User对象,密码加密PasswordEncoder来初步认识Spring Security。git
Spring Security 5.X 和Spring Security 4.X 在Http Basic认证有些不一样,在Spring Security4.X中,咱们想要使用Http Basic认证只须要以下代码:github
/** * @author developlee * @since 2018/11/17 22:43 */ @Configuration @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http.authorizeRequests() .antMatchers("/index").permitAll() .anyRequest().authenticated() .and().httpBasic(); super.configure(http); } }
Spring Security 是默认开启了 Http Basic认证的,若是想要关闭能够设置 security.basic.enabled: false (Spring Security5.X中已弃用) 而Spring Security 5.X的实现则有些不一样,若是按照以上代码,则访问连接时,会跳转至Spring Security 提供的默认登录页。接下来看看Spring Security5.X的实现,文档是这样描述的: 也就是说,要将BasicAuthenticationFilter添加到Spring Security的filterChain中。let's do it! 咱们先继承BasicAuthenticationEntryPoint,重写commence方法。spring
/** * @author developlee * @since 2018/11/25 11:36 */ @Component public class MyBasicAuthenticationEntryPoint extends BasicAuthenticationEntryPoint { @Override public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authException) throws IOException, ServletException { response.addHeader("WWW-Authenticate", "Basic realm=" + getRealmName()); response.setStatus(HttpServletResponse.SC_UNAUTHORIZED); PrintWriter printWriter = new PrintWriter(response.getOutputStream()); printWriter.write("Http Status 401: " + authException.getLocalizedMessage()); } @Override public void afterPropertiesSet() throws Exception { setRealmName("developlee"); super.afterPropertiesSet(); } }
接下来看看如何配置安全
/** * @author developlee * @since 2018/11/17 22:43 */ @Configuration @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { @Autowired private MyBasicAuthenticationEntryPoint authenticationEntryPoint; @Override protected void configure(HttpSecurity http) throws Exception { http.authorizeRequests() .antMatchers("/login").permitAll() .anyRequest().authenticated() .and().httpBasic() .authenticationEntryPoint(authenticationEntryPoint); } @Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { auth.inMemoryAuthentication().withUser("lensen").password(passwordEncoder().encode("123456")).authorities("ROLE_USER"); } @Bean protected PasswordEncoder passwordEncoder() { return new BCryptPasswordEncoder(); } }
LoginController.java的代码app
/** * @author developlee * @since 2018/11/17 22:02 */ @RestController public class LoginController { @GetMapping("/hello") public String hello() { return "hello"; } }
启动项目,访问咱们写好的连接地址。http://loalhost:8080/hello 框架
至此,Spring Security 5.X使用Http Basic 登录的实例便已经完成了。 本文的全部代码我已经放在个人github.com上,感谢您的观看,若是有什么错误的地方,还请指出,共同探讨!ide
