本文用示例的方式讲解,springsecurity,使用session方式,
用户名密码和手机验证码两种方式
非常简陋的登入页面

CustomAuthenticationFailureHandler 失败处理器
/**
认证失败处理器
**/
@Component
public class CustomAuthenticationFailureHandler extends SimpleUrlAuthenticationFailureHandler {
@Override
public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException{
response.setContentType("application/json;charset=UTF-8");
response.getWriter().write("认证失败");
}
}
CustomAuthenticationSuccessHandler 成功处理器
/**
认证成功处理器
**/
@Component
public class CustomAuthenticationSuccessHandler extends SavedRequestAwareAuthenticationSuccessHandler {
@Override
public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException{
response.setContentType("application/json;charset=UTF-8");
response.getWriter().write("认证成功");
}
}
CustomUserDetailsService 获取用户信息
/**
*
* 模拟从数据库获取用户信息,这里要注意的是,如果在配置的时候使用内存的方式,是不回使用该services
* SpringSecurityConfiguration方法中规定了使用那种方式管理用户信息,本例使用的是内存的方式
* 所以在用户名密码模式的时候,不回执行loadUserByUsername,手机登入的时候还是会走loadUserByUsername方法
*/
@Configuration
public class CustomUserDetailsService implements UserDetailsService {
@Autowired
PasswordEncoder passwordEncoder;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException{
//封装用户信息,用户名和密码和权限,注意这里要注意密码应该是加密的
//省略从数据库获取详细信息
return new User(username, "1234",
AuthorityUtils.commaSeparatedStringToAuthorityList("ADMIN"));
}
}
SpringSecurityConfiguration security整体配置
@Configuration
@EnableWebSecurity
public class SpringSecurityConfiguration extends WebSecurityConfigurerAdapter {
@Autowired
SecurityConfigurerAdapter mobileAuthenticationConfig;
@Override
protected void configure(HttpSecurity http) throws Exception{
http.csrf().disable()
.authorizeRequests()
.antMatchers("/login.html","/code/mobile").permitAll()
.anyRequest().authenticated()
.and()
.formLogin()
.successHandler(new CustomAuthenticationSuccessHandler())
.failureHandler(new CustomAuthenticationFailureHandler())
.loginPage("/login")
; //浏览器以form表单形式
//将手机验证码配置放到http中,这样mobileAuthenticationConfig配置就会生效
http.apply(mobileAuthenticationConfig);
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception{
// 用户信息存储在内存中
auth.inMemoryAuthentication().withUser("user")
.password(new BCryptPasswordEncoder().encode("1234")).authorities("ADMIN");
}
@Override
public void configure(WebSecurity web) {
web.ignoring().antMatchers("/code/mobile");
}
@Bean
public PasswordEncoder passwordEncoder(){
// 官网建议的加密方式,相同的密码,每次加密都不一样,安全性更好一点
return new BCryptPasswordEncoder();
}
}
CacheValidateCode 手机验证码的内存存储
/**
* 将手机验证码保存起来,后续验证中,实际项目中要放到redis等存储
**/
public class CacheValidateCode {
public static ConcurrentHashMap<String, String> cacheValidateCodeHashMap = new ConcurrentHashMap();
}
MobileAuthenticationConfig 手机验证码配置类,在SpringSecurityConfiguration中通过http.apply方式放到springsecurity中
/**
* 用于组合其他关于手机登录的组件
*/
@Component
public class MobileAuthenticationConfig
extends SecurityConfigurerAdapter<DefaultSecurityFilterChain, HttpSecurity> {
@Autowired
CustomAuthenticationSuccessHandler customAuthenticationSuccessHandler;
@Autowired

// 获取容器中已经存在的AuthenticationManager对象，并传入 mobileAuthenticationFilter 里面
mobileAuthenticationFilter.setAuthenticationManager(
http.getSharedObject(AuthenticationManager.class));
// 传入 失败与成功处理器
mobileAuthenticationFilter.setAuthenticationSuccessHandler(customAuthenticationSuccessHandler);
mobileAuthenticationFilter.setAuthenticationFailureHandler(customAuthenticationFailureHandler);
// 构建一个MobileAuthenticationProvider实例，接收 mobileUserDetailsService 通过手机号查询用户信息
MobileAuthenticationProvider provider = new MobileAuthenticationProvider();
provider.setUserDetailsService(mobileUserDetailsService);
// 将provider绑定到 HttpSecurity上，并将 手机号认证过滤器绑定到用户名密码认证过滤器之后
http.authenticationProvider(provider)
.addFilterAfter(mobileAuthenticationFilter, UsernamePasswordAuthenticationFilter.class);
}

MobileAuthenticationFilter 手机验证filter,完全模仿UsernamePasswordAuthenticationFilter

MobileAuthenticationProvider 手机验证处理器
/**

思路非常简单,就是定义了关于手机的验证filter,并放到security中,在通过验证码登入的时候,首先创建MobileAuthenticationToken,遍历所有的provider的时候,通过support方法获取到使用哪个provider,MobileAuthenticationProvider手机验证provider,验证手机号的验证码是否正确,如果正确就将MobileAuthenticationToken放到SecurityContextHolder中,保存在ThreadLocal变量中,该线程就能使用了,并且将MobileAuthenticationToken的authenticated设置为true,在security的最后一个拦截器FilterSecurityInterceptor判断是都已经验证过了,并且判断角色是否可以访问当前接口,
这样就是验证的整个流程,session的方式验证,在登入成功的时候token放到tomcat的内存中了,key就是sessionid,前端将session传到server时,从tomcat中获取已经验证过的token,这样就实现了登入后,其他接口可以正常访问的流程.
