SpringSecurity

Spring Security是一个能够为基于Spring的企业应用系统提供声明式的安全访问控制解决方案的安全框架

• 组成模块

配置

• 添加spring security 拦截链

@Overridepublic void onStartup(ServletContext servletContext) throws ServletException {    var a= servletContext.addFilter("springSecurityFilterChain", DelegatingFilterProxy.class);    a.addMappingForUrlPatterns(null,false,"/*");}

• 创建相关安全性配置

@Configuration@EnableWebSecuritypublic class SecurityConfig extends WebSecurityConfigurerAdapter {    @Override    protected void configure(HttpSecurity http) throws Exception {        http.authorizeRequests()            .anyRequest().authenticated()            .and()            .formLogin().and().httpBasic();    }}

添加用户

• 基于内存

@Override@Beanpublic UserDetailsService userDetailsService() {    User.UserBuilder users = User.builder();    InMemoryUserDetailsManager manager = new InMemoryUserDetailsManager();    manager.createUser(users.username("user")            .password(new BCryptPasswordEncoder().encode("123")).roles("USER")            .authorities("play")            .build()    );    manager.createUser(users.username("admin").password(new BCryptPasswordEncoder().encode("123")).roles("USER", "ADMIN").build());    return manager;}

• 基于数据库
• 基于LDAP

限制访问

@Overrideprotected void configure(HttpSecurity http) throws Exception {    http            .authorizeRequests()            .antMatchers("/").hasAnyAuthority("play")            .and()            .httpBasic();}

自定义错误页面

@Configurationpublic class WebServerAutoConfiguration {    @Bean    public ConfigurableServletWebServerFactory configurableServletWebServerFactory(){        TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory();        factory.addErrorPages(new ErrorPage(HttpStatus.FORBIDDEN,"/error/403"));        return factory;    }}

自定义登录页面

.formLogin().loginPage("/login").and().csrf().disable();

自定义认证成功失败处理

AuthenticationFailureHandler 认证失败接口AuthenticationSuccessHandler 认证成功接口

添加自定义用户服务

实现该接口

public interface UserDetailsService {	UserDetails loadUserByUsername(String username) throws UsernameNotFoundException;}

UserDetails需要实现的内容

public interface UserDetails extends Serializable {		Collection<? extends GrantedAuthority> getAuthorities();	String getPassword();	String getUsername();	boolean isAccountNonExpired();	boolean isAccountNonLocked();	boolean isCredentialsNonExpired();	boolean isEnabled();}                                            

自定义拦截请求

    @Override    protected void configure(HttpSecurity http) throws Exception {        System.out.println("auth pro run");        http                .authorizeRequests()                .antMatchers("/home").hasRole("ADMIN").and().formLogin().and()                .authorizeRequests()                .anyRequest().permitAll();    }

使用Spring表达式

    @Override    protected void configure(HttpSecurity http) throws Exception {        System.out.println("auth pro run");        http                .authorizeRequests()                .antMatchers("/home").access("hasRole('ADMIN') and hasIpAddress('::1')").and().formLogin().and()                .authorizeRequests()                .anyRequest().permitAll();    }

强制使用Https

@Overrideprotected void configure(HttpSecurity http) throws Exception {    System.out.println("auth pro run");    http            .authorizeRequests()            .antMatchers("/home").access("hasRole('ADMIN') and hasIpAddress('::1')").and().formLogin().and()            .authorizeRequests()            .anyRequest().permitAll().and().requiresChannel().anyRequest().requiresSecure();}

CSRF防御

使用HTTP Basic认证

 http                .authorizeRequests()                .antMatchers("/home").access("hasRole('ADMIN') and hasIpAddress('::1')").and().httpBasic().and()                .authorizeRequests()                .anyRequest().permitAll();

启用记住我功能

.and().httpBasic().and().rememberMe()

保护视图

• Spring Security的jsp标签库
• 使用thymeleaf的spring security 方言

保护方法调用

使用注解保护方法

• 配置

@Configuration@EnableGlobalMethodSecurity(securedEnabled = true)class Config1 extends GlobalMethodSecurityConfiguration{}

@Secured

@Secured("ROLE_ADMIN")@RequestMapping("/home")@ResponseBodypublic String home(){    return "home";}

使用表达式保护方法

• 启用相关配置支持

  @EnableGlobalMethodSecurity(prePostEnabled = true)

• 相关注解

  • @PreAuthorize :在方法调用前进行验证
  • @PostAuthorize：在方法调用后进行验证
  • @PreFilter :调用前对参数进行过滤
  • @PostFilter ：调用后对返回结果进行过滤

@PreAuthorize("#id == 10")public void invoke(Integer id){}

定义许可计算器

• 实现该接口

public interface PermissionEvaluator extends AopInfrastructureBean {    boolean hasPermission(Authentication authentication, Object targetDomainObject,            Object permission);    boolean hasPermission(Authentication authentication, Serializable targetId,            String targetType, Object permission);}

• 注册到Spring Security 中
