在Java配置文件中配置网关限流,可以使用Spring Cloud Gateway提供的限流过滤器来实现。具体步骤如下:
1. 在pom.xml文件中添加以下依赖:
```xml
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-gateway</artifactId>
</dependency>
```
2. 在application.yml中添加限流过滤器的配置:
```yaml
spring:
cloud:
gateway:
discovery:
locator:
enabled: true # 开启服务发现
routes:
- id: service-A # 路由id
uri: lb://service-A # 路由地址
predicates:
- Path=/service-A/** # 匹配路径
filters:
- name: RequestRateLimiter # 限流过滤器
args:
redis-rate-limiter.replenishRate: 10
redis-rate-limiter.burstCapacity: 20
```
3. 在代码中使用限流过滤器的配置:
```java
@Configuration
public class GatewayConfig {
@Autowired
private RedisConnectionFactory redisConnectionFactory;
@Bean
public RedisRateLimiter redisRateLimiter() {
return new RedisRateLimiter(10,20);
}
@Bean
public KeyResolver pathKeyResolver() {
return new PathKeyResolver();
}
@Bean
public RouteLocator customRouteLocator(RouteLocatorBuilder builder,
RedisRateLimiter redisRateLimiter,
KeyResolver pathKeyResolver) {
return builder.routes()
.route(r -> r.path("/service-A/**")
.filters(f -> f.requestRateLimiter(c -> c.setRateLimiter(redisRateLimiter))
.stripPrefix(1)
.filter(new RequestTimeFilter())
)
.uri("lb://service-A"))
.build();
}
}
```
以上是一些基本的配置,可以根据实际需求进行调整和优化。
