Spring Cloud Gateway熔断限流配置
在Spring Cloud Gateway中,可以使用Hystrix进行熔断限流。以下是一个简单的配置示例:
- 首先,确保你的项目中包含了Spring Cloud Gateway和Spring Cloud Netflix Hystrix依赖。
<dependencies>
<!-- Spring Cloud Gateway -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-gateway</artifactId>
</dependency>
<!-- Spring Cloud Netflix Hystrix -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
</dependency>
</dependencies>
- 在
application.yml
或application.properties
中配置Hystrix熔断器:
spring:
cloud:
gateway:
routes:
- id: my_route
uri: http://my-service
predicates:
- Path=/my-service/**
filters:
- name: Hystrix
args:
name: fallbackcmd
- name: RewritePath
args:
regexp: /my-service/(.*)
replacement: /$1
hystrix:
command:
default:
execution:
isolation:
thread:
timeoutInMilliseconds: 1000
在这个配置中,我们定义了一个名为my_route
的路由,并为其配置了Hystrix熔断器。我们设置了熔断器的名称为fallbackcmd
,并指定了熔断时的回退逻辑。
- 实现回退逻辑:
@Component
public class FallbackHandlerRoute implements FallbackProvider {
@Override
public String getRoute() {
return "*"; // 表示该回退逻辑适用于所有路由
}
@Override
public ClientHttpResponse fallbackResponse(Throwable cause) {
// 这里可以实现自定义的回退响应逻辑
return new ClientHttpResponse() {
@Override
public HttpStatus getStatusCode() throws IOException {
return HttpStatus.SERVICE_UNAVAILABLE;
}
@Override
public int getRawStatusCode() throws IOException {
return 503;
}
@Override
public String getStatusText() throws IOException {
