一、Spring Boot集成Spring Security之自动装配
二、实现功能及软件版本说明
- 使用Spring Boot集成Spring Security实现Servlet项目的安全个性化配置
- Spring Boot版本:2.7.18
- Spring Security版本:5.7.11
三、创建Spring Boot项目
-
创建Spring Boot项目,目录结构如下
-
引入Spring Security包,完整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>
四、查看自动装配配置类
-
查看Security Servlet相关自动装配配置类
五、自动装配配置类之SecurityAutoConfiguration
1、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
- 导入SpringBootWebSecurityConfiguration
3、SpringBootWebSecurityConfiguration
1)、部分源码
@Configuration(proxyBeanMethods = false)
@ConditionalOnWebApplication(type = Type.SERVLET)
class SpringBootWebSecurityConfiguration {
@Configuration(proxyBeanMethods = false)
@ConditionalOnDefaultWebSecurity
static 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)
@EnableWebSecurity
static class WebSecurityEnablerConfiguration {
}
}
2)、主要作用
- 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
- 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
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;
}
2)、主要作用
- 导入WebSecurityConfiguration
- 导入HttpSecurityConfiguration
5、WebSecurityConfiguration
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();
}
}
2)、主要作用
- 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容器中注册SecurityFilterChain对象
- 没有默认的过滤器链时,使用WebSecurityConfigurerAdapter中默认配置生成过滤器链
- 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
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:off
http
.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:on
applyDefaultConfigurers(http);
return http;
}
}
2)、主要作用
- Spring容器中注册HttpSecurity对象
- httpSecurity用于配置构建自定义过滤器链
六、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
@Lazy
public 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
- 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)
- 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<>();
}
- 通过配置文件可以修改默认用户名、密码、角色(示例如下)
七、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
- 注册DelegatingFilterProxyRegistrationBean(委托过滤器代理注册Bean)
- 设置代理目标Bean对象名称为springSecurityFilterChain
