一、实现功能及软件版本说明

1. 使用Spring Boot集成Spring Security实现Servlet项目的安全个性化配置
2. Spring Boot版本：2.7.18
3. Spring Security版本：5.7.11

二、创建Spring Boot项目

1. 创建Spring Boot项目，目录结构如下
   
2. 引入Spring Security包，完成pom.xml如下

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.7.18</version><relativePath/></parent><groupId>com.yu</groupId><artifactId>spring-boot-security2-demo</artifactId><version>0.0.1-SNAPSHOT</version><name>spring-boot-security2-demo</name><description>Spring Boot集成Spring Security样例</description><properties><java.version>8</java.version></properties><dependencies><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></dependencies></project>

三、查看自动装配配置类

1. 查看Security Servlet相关自动装配配置类
   

四、自动装配配置类之SecurityAutoConfiguration

1、SecurityAutoConfiguration部分源码

@AutoConfiguration
@ConditionalOnClass(DefaultAuthenticationEventPublisher.class)
@EnableConfigurationProperties(SecurityProperties.class)
@Import({ SpringBootWebSecurityConfiguration.class, SecurityDataConfiguration.class })
public class SecurityAutoConfiguration {@Bean@ConditionalOnMissingBean(AuthenticationEventPublisher.class)public DefaultAuthenticationEventPublisher authenticationEventPublisher(ApplicationEventPublisher publisher) {return new DefaultAuthenticationEventPublisher(publisher);}}

2、主要作用

1. 导入SpringBootWebSecurityConfiguration

3、SpringBootWebSecurityConfiguration

3.1、SpringBootWebSecurityConfiguration部分源码

@Configuration(proxyBeanMethods = false)
@ConditionalOnWebApplication(type = Type.SERVLET)
class SpringBootWebSecurityConfiguration {@Configuration(proxyBeanMethods = false)@ConditionalOnDefaultWebSecuritystatic class SecurityFilterChainConfiguration {@Bean@Order(SecurityProperties.BASIC_AUTH_ORDER)SecurityFilterChain defaultSecurityFilterChain(HttpSecurity http) throws Exception {http.authorizeRequests().anyRequest().authenticated();http.formLogin();http.httpBasic();return http.build();}}@Configuration(proxyBeanMethods = false)@ConditionalOnMissingBean(name = BeanIds.SPRING_SECURITY_FILTER_CHAIN)@ConditionalOnClass(EnableWebSecurity.class)@EnableWebSecuritystatic class WebSecurityEnablerConfiguration {}}

3.2、主要作用

1. 默认Security配置（Spring容器中没有SecurityFilterChain和WebSecurityConfigurerAdapter）时，向Spring容器中注入默认过滤器链，即用户没有自定义过滤器链时，生成默认过滤器链
   
2. Spring容器中不存在名称为springSecurityFilterChain对象时，启用WebSecurity，即用户未显示的启用WebSecurity时，隐式的启用WebSecurity
   

4、@EnableWebSecurity

4.1、部分源码

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
@Documented
@Import({ WebSecurityConfiguration.class, SpringWebMvcImportSelector.class, OAuth2ImportSelector.class,HttpSecurityConfiguration.class })
@EnableGlobalAuthentication
@Configuration
public @interface EnableWebSecurity {/*** Controls debugging support for Spring Security. Default is false.* @return if true, enables debug support with Spring Security*/boolean debug() default false;}

4.2、主要作用

1. 导入WebSecurityConfiguration
2. 导入HttpSecurityConfiguration

5、WebSecurityConfiguration

5.1、部分源码

@Configuration(proxyBeanMethods = false)
public class WebSecurityConfiguration implements ImportAware, BeanClassLoaderAware {
@Bean(name = AbstractSecurityWebApplicationInitializer.DEFAULT_FILTER_NAME)public Filter springSecurityFilterChain() throws Exception {boolean hasConfigurers = this.webSecurityConfigurers != null && !this.webSecurityConfigurers.isEmpty();boolean hasFilterChain = !this.securityFilterChains.isEmpty();Assert.state(!(hasConfigurers && hasFilterChain),"Found WebSecurityConfigurerAdapter as well as SecurityFilterChain. Please select just one.");if (!hasConfigurers && !hasFilterChain) {WebSecurityConfigurerAdapter adapter = this.objectObjectPostProcessor.postProcess(new WebSecurityConfigurerAdapter() {});this.webSecurity.apply(adapter);}for (SecurityFilterChain securityFilterChain : this.securityFilterChains) {this.webSecurity.addSecurityFilterChainBuilder(() -> securityFilterChain);for (Filter filter : securityFilterChain.getFilters()) {if (filter instanceof FilterSecurityInterceptor) {this.webSecurity.securityInterceptor((FilterSecurityInterceptor) filter);break;}}}for (WebSecurityCustomizer customizer : this.webSecurityCustomizers) {customizer.customize(this.webSecurity);}return this.webSecurity.build();}
}

5.2、主要作用

1. 两种方式注册过滤器链：
   • 继承WebSecurityConfigurerAdapter（本质是实现SecurityConfigurer接口） （已弃用）
   • 直接向Spring容器种注册SecurityFilterChain对象
2. 没有默认的过滤器链时，使用WebSecurityConfigurerAdapter中默认配置生成过滤器链
3. 根据配置的SecurityFilterChain集合构建FilterChainProxy类型的对象并注入到Spring容器中名称为springSecurityFilterChain

6、HttpSecurityConfiguration

6.1、部分源码

@Configuration(proxyBeanMethods = false)
class HttpSecurityConfiguration {@Bean(HTTPSECURITY_BEAN_NAME)@Scope("prototype")HttpSecurity httpSecurity() throws Exception {WebSecurityConfigurerAdapter.LazyPasswordEncoder passwordEncoder = new WebSecurityConfigurerAdapter.LazyPasswordEncoder(this.context);AuthenticationManagerBuilder authenticationBuilder = new WebSecurityConfigurerAdapter.DefaultPasswordEncoderAuthenticationManagerBuilder(this.objectPostProcessor, passwordEncoder);authenticationBuilder.parentAuthenticationManager(authenticationManager());authenticationBuilder.authenticationEventPublisher(getAuthenticationEventPublisher());HttpSecurity http = new HttpSecurity(this.objectPostProcessor, authenticationBuilder, createSharedObjects());// @formatter:offhttp.csrf(withDefaults()).addFilter(new WebAsyncManagerIntegrationFilter()).exceptionHandling(withDefaults()).headers(withDefaults()).sessionManagement(withDefaults()).securityContext(withDefaults()).requestCache(withDefaults()).anonymous(withDefaults()).servletApi(withDefaults()).apply(new DefaultLoginPageConfigurer<>());http.logout(withDefaults());// @formatter:onapplyDefaultConfigurers(http);return http;}
}

6.2、主要作用

1. Spring容器中注册HttpSecurity对象
2. httpSecurity用于配置构建自定义过滤器链

五、自动装配配置类之UserDetailsServiceAutoConfiguration

1、部分源码

@AutoConfiguration
@ConditionalOnClass(AuthenticationManager.class)
@ConditionalOnBean(ObjectPostProcessor.class)
@ConditionalOnMissingBean(value = { AuthenticationManager.class, AuthenticationProvider.class, UserDetailsService.class,AuthenticationManagerResolver.class },type = { "org.springframework.security.oauth2.jwt.JwtDecoder","org.springframework.security.oauth2.server.resource.introspection.OpaqueTokenIntrospector","org.springframework.security.oauth2.client.registration.ClientRegistrationRepository","org.springframework.security.saml2.provider.service.registration.RelyingPartyRegistrationRepository" })
public class UserDetailsServiceAutoConfiguration {@Bean@Lazypublic InMemoryUserDetailsManager inMemoryUserDetailsManager(SecurityProperties properties,ObjectProvider<PasswordEncoder> passwordEncoder) {SecurityProperties.User user = properties.getUser();List<String> roles = user.getRoles();return new InMemoryUserDetailsManager(User.withUsername(user.getName()).password(getOrDeducePassword(user, passwordEncoder.getIfAvailable())).roles(StringUtils.toStringArray(roles)).build());}private String getOrDeducePassword(SecurityProperties.User user, PasswordEncoder encoder) {String password = user.getPassword();if (user.isPasswordGenerated()) {logger.warn(String.format("%n%nUsing generated security password: %s%n%nThis generated password is for development use only. "+ "Your security configuration must be updated before running your application in "+ "production.%n",user.getPassword()));}if (encoder != null || PASSWORD_ALGORITHM_PATTERN.matcher(password).matches()) {return password;}return NOOP_PASSWORD_PREFIX + password;}

2、主要作用

1. 用户未自定义认证接口时，生成默认认证接口inMemoryUserDetailsManager（基于内存用户认证）
2. 生成默认名称为user，密码为随机生成的uuid（项目启动时会打印在控制台中），角色为空的用户存入内存中

#UserDetailsServiceAutoConfiguration.inMemoryUserDetailsManager方法中获取user对象
SecurityProperties.User user = properties.getUser();
#SecurityProperties中的User类
public static class User {private String name = "user";private String password = UUID.randomUUID().toString();private List<String> roles = new ArrayList<>();}

3. 通过配置文件可以修改默认用户名、密码、角色（示例如下）
   

六、自动装配配置类之SecurityFilterAutoConfiguration

1、部分源码

@AutoConfiguration(after = SecurityAutoConfiguration.class)
@ConditionalOnWebApplication(type = Type.SERVLET)
@EnableConfigurationProperties(SecurityProperties.class)
@ConditionalOnClass({ AbstractSecurityWebApplicationInitializer.class, SessionCreationPolicy.class })
public class SecurityFilterAutoConfiguration {private static final String DEFAULT_FILTER_NAME = AbstractSecurityWebApplicationInitializer.DEFAULT_FILTER_NAME;@Bean@ConditionalOnBean(name = DEFAULT_FILTER_NAME)public DelegatingFilterProxyRegistrationBean securityFilterChainRegistration(SecurityProperties securityProperties) {DelegatingFilterProxyRegistrationBean registration = new DelegatingFilterProxyRegistrationBean(DEFAULT_FILTER_NAME);registration.setOrder(securityProperties.getFilter().getOrder());registration.setDispatcherTypes(getDispatcherTypes(securityProperties));return registration;}private EnumSet<DispatcherType> getDispatcherTypes(SecurityProperties securityProperties) {if (securityProperties.getFilter().getDispatcherTypes() == null) {return null;}return securityProperties.getFilter().getDispatcherTypes().stream().map((type) -> DispatcherType.valueOf(type.name())).collect(Collectors.toCollection(() -> EnumSet.noneOf(DispatcherType.class)));}}

2、主要作用

1. 注册DelegatingFilterProxyRegistrationBean（委托过滤器代理注册Bean）
2. 设置代理目标Bean对象名称为springSecurityFilterChain
