我似乎找不到如何启用hystrix。SpringBoot2.0中的流。当我试图访问文件时,转到http://localhost:8080/hystrix.stream我得到一个404文件未找到错误。
在控制器中调用的方法:
@GetMapping("/")
public Mono<String> index(Model model) {
model.addAttribute("images",
imageService
.findAllImages()
.map(image -> new HashMap<String, Object>() {{
put("id", image.getId());
put("name", image.getName());
put("imageComments", commentHelper.getComments(image));
}})
);
return Mono.just("index");
}
CommentHelper代码,请注意正在使用@HystrixCommand:
@Component
public class CommentHelper {
private final RestTemplate restTemplate;
CommentHelper(RestTemplate restTemplate) {
this.restTemplate = restTemplate;
}
@HystrixCommand(fallbackMethod = "defaultComments")
public List<Comment> getComments(Image image) {
return restTemplate.exchange(
"http://COMMENTS/comments/{imageId}",
HttpMethod.GET,
null,
new ParameterizedTypeReference<List<Comment>>() {},
image.getId()).getBody();
}
public List<Comment> defaultComments(Image image) {
return Collections.emptyList();
}
}
这些是来自构建的依赖项。格拉德尔:
dependencies {
compile 'org.springframework.boot:spring-boot-starter-webflux'
compile 'org.synchronoss.cloud:nio-multipart-parser'
compile 'org.springframework.boot:spring-boot-starter-data-mongodb-reactive'
compile 'org.springframework.boot:spring-boot-starter-thymeleaf'
compile 'org.springframework.boot:spring-boot-starter-actuator'
compile 'org.springframework.boot:spring-boot-devtools'
compile 'org.springframework.cloud:spring-cloud-starter-stream-rabbit'
compile 'org.springframework.cloud:spring-cloud-stream-reactive'
compile 'org.springframework.cloud:spring-cloud-starter-netflix-eureka-client'
compile 'org.springframework.cloud:spring-cloud-starter-netflix-hystrix'
testCompile 'org.springframework.boot:spring-boot-starter-test'
testCompile 'io.projectreactor:reactor-test'
compile 'junit:junit:4.12'
}
当我进入http://localhost:8080/application/features时,您可以看到Hystrix已启用,如下所示:
{
"enabled": [
{
"type": "com.netflix.hystrix.contrib.javanica.aop.aspectj.HystrixCommandAspect",
"name": "Hystrix",
"version": "1.5.12",
"vendor": null
},
{
"type": "com.netflix.discovery.EurekaClient",
"name": "Eureka Client",
"version": "1.8.4",
"vendor": null
},
{
"type": "org.springframework.cloud.client.discovery.composite.CompositeDiscoveryClient",
"name": "DiscoveryClient",
"version": "2.0.0.M3",
"vendor": "Pivotal Software, Inc."
},
{
"type": "org.springframework.cloud.netflix.ribbon.RibbonLoadBalancerClient",
"name": "LoadBalancerClient",
"version": "2.0.0.M3",
"vendor": "Pivotal Software, Inc."
},
{
"type": "com.netflix.ribbon.Ribbon",
"name": "Ribbon",
"version": "2.2.2",
"vendor": null
}
],
"disabled": []
}
这里到底出了什么问题?如果有帮助的话,我将尝试按照这里找到的代码进行操作
