新的spring boot3.x和spring-security6.x的流程

news 2026/5/12 17:20:21

以下是Spring Boot 3.x与Spring Security 6.x的核心流程及关键配置要点：

依赖配置

在pom.xml或build.gradle中添加依赖：

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency>

基础安全配置

创建配置类继承WebSecurityConfigurerAdapter（已废弃）或直接使用SecurityFilterChainBean：

@Configuration @EnableWebSecurity public class SecurityConfig { @Bean public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception { http .authorizeHttpRequests(auth -> auth .requestMatchers("/public/**").permitAll() .anyRequest().authenticated() ) .formLogin(form -> form .loginPage("/login") .permitAll() ); return http.build(); } }

认证流程

基于内存的认证示例：

@Bean public UserDetailsService userDetailsService() { UserDetails user = User.withDefaultPasswordEncoder() .username("user") .password("password") .roles("USER") .build(); return new InMemoryUserDetailsManager(user); }

数据库认证：

@Bean public UserDetailsService userDetailsService(DataSource dataSource) { return new JdbcUserDetailsManager(dataSource); }

密码编码

强制使用加密算法（Spring Security 6默认要求）：

@Bean public PasswordEncoder passwordEncoder() { return PasswordEncoderFactories.createDelegatingPasswordEncoder(); }

CSRF保护

默认启用，可通过以下方式禁用（不推荐）：

http.csrf(csrf -> csrf.disable());

方法级安全

启用注解支持：

@Configuration @EnableMethodSecurity public class MethodSecurityConfig { }

使用示例：

@PreAuthorize("hasRole('ADMIN')") public void adminOnlyMethod() {}

OAuth2资源服务器

配置JWT验证：

@Bean SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception { http .authorizeHttpRequests(auth -> auth .anyRequest().authenticated() ) .oauth2ResourceServer(oauth2 -> oauth2 .jwt(jwt -> jwt .decoder(jwtDecoder()) ) ); return http.build(); } @Bean JwtDecoder jwtDecoder() { return NimbusJwtDecoder.withJwkSetUri("https://idp.example.com/jwks").build(); }

响应式安全配置

对于WebFlux应用：

@Bean SecurityWebFilterChain securityWebFilterChain(ServerHttpSecurity http) { return http .authorizeExchange(exchanges -> exchanges .pathMatchers("/public/**").permitAll() .anyExchange().authenticated() ) .formLogin(form -> form .loginPage("/login") ) .build(); }

关键变更注意点

移除WebSecurityConfigurerAdapter，改用SecurityFilterChainBean
默认拒绝所有未明确放行的请求
必须明确配置密码编码器
授权规则使用新的authorizeHttpRequests代替authorizeRequests
默认CSRF保护启用且更严格

以上流程覆盖了从基础配置到高级集成的核心环节，实际应用时需根据具体需求调整安全策略。
