Spring Session
简介
Spring Session 提供了用于管理用户会话信息相关的 API 和实现。
使用方式
引入如下依赖：

| dependencies {
implementation 'org.springframework.boot:spring-boot-starter-data-redis'
implementation 'org.springframework.boot:spring-boot-starter-security'
implementation 'org.springframework.boot:spring-boot-starter-web'
implementation 'org.springframework.session:spring-session-data-redis'
compileOnly 'org.projectlombok:lombok'
developmentOnly 'org.springframework.boot:spring-boot-devtools'
annotationProcessor 'org.projectlombok:lombok'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
testImplementation 'org.springframework.security:spring-security-test'
}

然后在主类上添加 @EnableRedisHttpSession 注解即可：

import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;
@EnableRedisHttpSession
@SpringBootApplication
public class SessionRedisApplication {
public static void main(String[] args) {
SpringApplication.run(SessionRedisApplication.class, args);
}
}

@EnableWebSecurity

@Bean
public InMemoryUserDetailsManager userDetailsService(PasswordEncoder passwordEncoder) {

.password(passwordEncoder.encode("admin"))
.roles("ADMIN")
.build();
return new InMemoryUserDetailsManager(user);
}
@Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
http
.authorizeHttpRequests((authorize) -> authorize
.dispatcherTypeMatchers(FORWARD, ERROR).permitAll()
.requestMatchers("/login").permitAll()
.anyRequest().authenticated()
)
.formLogin(Customizer.withDefaults());
return http.build();
}
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
}

编写项目配置文件：

| spring:
data:
redis:
host: xxx.xxx.xxx.xxx
port: 6379

启动程序并进行登录即可在 Redis 中看到 Session 信息。
