网关gateway和springsecurity的整合
Spring Security和Spring Cloud Gateway的整合主要涉及到路由安全配置,以下是一个基本的示例:
- 添加依赖(确保Spring Security和Spring Cloud Gateway的版本兼容):
<!-- Spring Cloud Gateway -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-gateway</artifactId>
</dependency>
<!-- Spring Security -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
- 配置Spring Security,设置基本的用户和权限:
@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication()
.withUser("user")
.password(passwordEncoder().encode("password"))
.authorities("ROLE_USER");
}
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable() // 禁用CSRF保护
.authorizeRequests()
.anyRequest().authenticated() // 所有请求都需要认证
.and()
.httpBasic(); // 使用HTTP Basic认证
}
}
- 配置Spring Cloud Gateway,为特定路由添加安全验证:
@Configuration
public class GatewayConfig {
@Bean
public RouteLocator customRouteLocator(RouteLocator routeLocator) {
return routeLocator.routes()
.route("secure-route", r -> r.path("/secure/**")
.filters(f -> f.requestRateLimiter(config -> config.setKeyResolver(new MyKeyResolver())))
.uri("http://localhost:8081")
.id("secure_route")
)
.build();
}
public static class MyKeyResolver implements KeyResolver {
@Override
public Mono<String> resolve(ServerWebExchange exchange) {
return Mono.just(exchange.getRequest().getHeaders().getFirst("X-Request-Id"));
}
}
}
在上述配置中,我们定义了一个名为"secure-route"的路由,它匹配所有进入"/secure/**"的请求,并且我们通过filters
添加了限流功能,其中MyKeyResolver
类用于从请求头中提取限流的关键字。
确保你的应用程序配置了Spring Security,并且在请求头中携带了正确的认证信息。Spring Security会处理所有安全相关的事务,包括用户认证和授权。Spring Cloud Gateway将请求代理到后端服务。
