QUESTION

Can one setup Spring Boot 2.6 and Spring Cloud 2021.x to use Ribbon and Hystrix with Spring WebClient and Feign?

Asked 2022-Apr-12 at 10:13

I know that Spring Cloud at some version (3.0?) dropped direct support for some Netflix libraries like Ribbon or Hystrix. Now I'm trying to make a smooth migration of around 20 microservices running on production having some custom code extending Ribbon (and Hystrix to a lesser degree). The main goal is to upgrade from Spring Boot 2.3 to 2.6. As a consequence I need to upgrade Spring Cloud to 3.1.x, right?

My guess was to proceed with 2-step upgrade to avoid a one big-step migration:

Upgrade to Spring Boot 2.6 and Spring Cloud 3.1 while still using Ribbon and Hystrix
Make a way through a jungle of an old code and getting rid of Ribbon and Hystrix in smaller increments.

However to achieve this I'm trying to use simultanously Spring Boot 2.6, Spring Cloud with release train 2021.01 and 2 selected starters from older Spring Cloud (latest versions of these artifacts):

spring-cloud-starter-netflix-hystrix 2.2.10.RELEASE
spring-cloud-starter-netflix-ribbon 2.2.10.RELEASE

Is this possible at all? We are heavilly using Feign and Spring WebClient - client-side load-balancing must work for these. So far I found out Feign clients are not automatically integrated with Ribbon.

@spencergibb @OlgaMaciaszek - especially counting on you.

Answered 2022-Apr-12 at 10:13

Answering my own question after receiving confirmation from Spring Cloud team by other means: this is a bad idea to try use Ribbon with Spring Cloud 2021.01 and it would require a really hard work to make it working.

I think you question has been already answered; please, consider review this SO question.

You need to include the following dependency:

implementation 'org.springframework.cloud:spring-cloud-starter-netflix-hystrix:2.2.10.RELEASE'

Because you are using Spring BOM maybe this will be enough:

implementation 'org.springframework.cloud:spring-cloud-starter-netflix-hystrix'

ANSWER

Answered 2022-Mar-06 at 15:36

There’s a relatively new Gradle feature called “version catalogs”. With those you can centrally declare dependencies that you’d like to share between multiple projects of your build (or even between different builds).

In your concrete example, you’d add something like the following to your settings.gradle file:

dependencyResolutionManagement {
    versionCatalogs {
        libs {
            library('spring-cloud-bom', 'org.springframework.cloud:spring-cloud-dependencies:2021.0.1')
            library('spring-cloud-starter', 'org.springframework.cloud', 'spring-cloud-starter-netflix-eureka-client').withoutVersion()
            library('spring-boot-starter-validation', 'org.springframework.boot', 'spring-boot-starter-validation').withoutVersion()
            library('spring-boot-starter-test', 'org.springframework.boot', 'spring-boot-starter-test').withoutVersion()
            library('threetenbp', 'org.threeten:threetenbp:1.5.1')
            library('spring-boot-starter-actuator', 'org.springframework.boot', 'spring-boot-starter-actuator').withoutVersion()
            library('lombok', 'org.projectlombok:lombok:1.18.22')
            library('springfox-boot-starter', 'io.springfox:springfox-boot-starter:3.0.0')
            library('spring-boot-starter-hateoas', 'org.springframework.boot:spring-boot-starter-hateoas:2.6.3')
            library('hysterix-core', 'com.netflix.hystrix:hystrix-core:1.5.18')
            library('spring-security-core', 'org.springframework.security:spring-security-core:5.6.1')
            library('junit-jupiter-api', 'org.junit.jupiter:junit-jupiter-api:5.8.2')
            library('junit-jupiter-engine', 'org.junit.jupiter:junit-jupiter-engine:5.8.2')
        }
    }
}

Then, in both build.gradle files, you’d replace your dependencies blocks with the following:

dependencies {
    implementation libs.spring.cloud.starter
    implementation libs.spring.boot.starter.validation
    testImplementation libs.spring.boot.starter.test
    implementation libs.threetenbp
    implementation libs.spring.boot.starter.actuator
    // Lombok
    compileOnly libs.lombok
    annotationProcessor libs.lombok
    testCompileOnly libs.lombok
    testAnnotationProcessor libs.lombok
    // Swagger
    implementation libs.springfox.boot.starter
    implementation libs.spring.boot.starter.hateoas
    implementation libs.hysterix.core
    implementation libs.spring.security.core
    testImplementation libs.junit.jupiter.api
    testRuntimeOnly libs.junit.jupiter.engine
}

As you’re using a Maven BOM for Spring, you’ll also have to use the following updated dependencyManagement block in all projects:

dependencyManagement {
    imports {
        mavenBom libs.spring.cloud.bom.get().toString()
    }
    resolutionStrategy {
        cacheDynamicVersionsFor 0, "seconds"
        cacheChangingModulesFor 0, "seconds"
    }
}

That should be it. I could successfully test your sample build configurations with my updates at least on Gradle 7.4.

After Some research I found that Ribbon, Zuul are in maintenance mode and we won't get any new version and spring also came up with alternative for Ribbon, Zuul etc. Please refer this link for spring alternative for load balancing, proxy server etc

And for this issue I used spring cloud gateway instead of Zuul which is the alternative provided by spring

Override Hysterix Logging

Asked 2021-Dec-10 at 15:21

I am trying to understand the logs generated by SpringBoot before and after implementing Hysterix Circuit Breaker

Before Hystrix the logs looked like,

17:31:35.977 [http-nio-8080-exec-2] [TransID:bcc8a9e9-41b7-47c8-9eb1-0f8becb42f68] INFO  c.f.e.common.logging.MethodLogging - Entered Class: class com.org.myapp.service.MyService, Method: getData, Arguments: 123456

After implementing Hystrix the logs looks like,

17:21:23.197 [hystrix-MyController-1] [TransID:] INFO  c.f.e.common.logging.MethodLogging - Entered Class: class com.org.myapp.service.MyService, Method: getData, Arguments: 123456

So, how did http-nio-8080-exec-2 get replaced with hystrix-OrchestratorController-1, and why it's not showing my TransactionId when Hystrix got implemented. How did Hystrix take over the logging? What's the difference between both? Is there any way to revert back to my old logging format? I tried hystrix.command.default.requestLog.enabled=false in my application.properties, but no luck.

Main class

@SpringBootApplication
@EnableCircuitBreaker
class MyApp{
}

RestController

@GetMapping("...")
@HystrixCommand(commandKey="data")
public Object getData(){
}

application.properties

hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=5000

ANSWER

Answered 2021-Dec-10 at 15:21

Hystrix is using its own thread instead of the local thread. That's the reason your log looks different.

Add this property in your application.properties

hystrix.command.default.execution.isolation.strategy=SEMAPHORE

Now hystrix will use your local thread.

we were not setting HBASE_CLIENT_IPC_POOL_SIZE, by default it was 1.

After setting it to 3, we did not see the issue anymore.

Spring Cloud Version compatible for Spring Boot 2.5.5

Asked 2021-Nov-01 at 14:02

I'm trying to build a microservice application which will be using Hystrix and some distributed tracing from Spring Cloud. When i tried using Spring Cloud version '2021.0.0-M3' for the Spring boot version '2.5.5' I get below error while startup:

***Your project setup is incompatible with our requirements due to following reasons:

Spring Boot [2.5.5] is not compatible with this Spring Cloud release train***

Is there a compatibility matrix between spring boot and Spring Cloud.

QUESTION

How do you override the Hystrix configuration for OpenFeign?

Asked 2021-Sep-15 at 20:40

How do you override the Hystrix default configuration for OpenFeign? Most of the documentation out there is for SpringBoot + OpenFeign, which has its own Spring-specific configuration override system.

Ideally it would be possible to configure the Hystrix core size for the client and configure and timeouts on a per endpoint basis.

ANSWER

Answered 2021-Sep-15 at 20:40

Hystrix OpenFeign has a setterFactory() method on the builder that allows you to pass in a SetterFactory lambda function that is executed when setting up each target endpoint:

final SetterFactory hystrixConfigurationFactory = (target, method) -> {
    final String groupKey = target.name();
    final String commandKey = method.getAnnotation(RequestLine.class).value();

    // Configure default thread pool properties
    final HystrixThreadPoolProperties.Setter hystrixThreadPoolProperties = HystrixThreadPoolProperties.Setter()
        .withCoreSize(50)
        .withMaximumSize(200)
        .withAllowMaximumSizeToDivergeFromCoreSize(true);

    return HystrixCommand.Setter
        .withGroupKey(HystrixCommandGroupKey.Factory.asKey(groupKey))
        .andCommandKey(HystrixCommandKey.Factory.asKey(commandKey))
        .andThreadPoolPropertiesDefaults(hystrixThreadPoolProperties);;
};

final MyTargetClient myTargetClient = HystrixFeign.builder()
    .setterFactory(hystrixConfigurationFactory)
    .client(new OkHttpClient())
    .encoder(new JacksonEncoder(objectMapper))
    .decoder(new JacksonDecoder(objectMapper))
    .target(new Target.HardCodedTarget<>(MyTargetClient.class, "customclientname", baseUrl))

The above example uses boilerplate from the OpenFeign documentation to properly name Hystrix keys based on the target endpoint function. It then goes further by also configuring the default thread pool property core size and maximum core size as a default for all of the target functions.

However, since this factory is called for each target endpoint, we can actually override the Hystrix configuration on a per endpoint basis. A use good case for this is Hystrix timeouts: sometimes there are endpoints that take longer than others and we need to account for that.

The easiest way would be to first create an annotation and place it on the target endpoints that need to be overridden:

/**
 * Override Hystrix configuration for Feign targets.
 */
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
@interface HystrixOverride {
    int DEFAULT_EXECUTION_TIMEOUT = 2_000;

    /**
     * Execution timeout in milliseconds.
     */
    int executionTimeout() default DEFAULT_EXECUTION_TIMEOUT;
}

interface MyTargetClient {
    @HystrixOverride(executionTimeout = 10_000)
    @RequestLine("GET /rest/{storeCode}/V1/products")
    Products searchProducts(@Param("storeCode") String storeCode, @QueryMap Map queryMap);

    @RequestLine("GET /rest/{storeCode}/V1/products/{sku}")
    Product getProduct(@Param("storeCode") String storeCode, @Param("sku") String sku);
}

In the above example, the search API might take a little longer to load so we have an override for that.

Just putting the override annotation on the target endpoint function is not enough though. We need to go back to our factory and update it to use the data in the annotations:

final SetterFactory hystrixConfigurationFactory = (target, method) -> {
    final String groupKey = target.name();
    final String commandKey = method.getAnnotation(RequestLine.class).value();

    // Configure per-function Hystrix configuration by referencing annotations
    final HystrixCommandProperties.Setter hystrixCommandProperties = HystrixCommandProperties.Setter();
    final HystrixOverride hystrixOverride = method.getAnnotation(HystrixOverride.class);

    final int executionTimeout = (hystrixOverride == null)
        ? HystrixOverride.DEFAULT_EXECUTION_TIMEOUT
        : hystrixOverride.executionTimeout();
    hystrixCommandProperties.withExecutionTimeoutInMilliseconds(executionTimeout);

    // Configure default thread pool properties
    final HystrixThreadPoolProperties.Setter hystrixThreadPoolProperties = HystrixThreadPoolProperties.Setter()
        .withCoreSize(50)
        .withMaximumSize(200)
        .withAllowMaximumSizeToDivergeFromCoreSize(true);

    return HystrixCommand.Setter
        .withGroupKey(HystrixCommandGroupKey.Factory.asKey(groupKey))
        .andCommandKey(HystrixCommandKey.Factory.asKey(commandKey))
        .andCommandPropertiesDefaults(hystrixCommandProperties)
        .andThreadPoolPropertiesDefaults(hystrixThreadPoolProperties);;
};

The above checks that an override annotation exists and then uses the data in that annotation to configure the execution timeout for that target endpoint. If the override is not present, the default for the HystrixOverride endpoint will be used instead. The resulting hystrixCommandProperties variable is then plugged in to the overall HystrixCommand.Setter at the end.
