2. Spring Cloud Commons: Common Abstractions

Patterns such as service discovery, load balancing, and circuit breakers lend themselves to a common abstraction layer that can be consumed by all Spring Cloud clients, independent of the implementation (for example, discovery with Eureka or Consul).

2.1 @EnableDiscoveryClient

Spring Cloud Commons provides the @EnableDiscoveryClient annotation. This looks for implementations of the DiscoveryClient interface with META-INF/spring.factories. Implementations of the Discovery Client add a configuration class to spring.factories under the org.springframework.cloud.client.discovery.EnableDiscoveryClient key. -Examples of DiscoveryClient implementations include Spring Cloud Netflix Eureka, Spring Cloud Consul Discovery, and Spring Cloud Zookeeper Discovery.

By default, implementations of DiscoveryClient auto-register the local Spring Boot server with the remote discovery server. +Examples of DiscoveryClient implementations include Spring Cloud Netflix Eureka, Spring Cloud Consul Discovery, and Spring Cloud Zookeeper Discovery.

By default, implementations of DiscoveryClient auto-register the local Spring Boot server with the remote discovery server. This behavior can be disabled by setting autoRegister=false in @EnableDiscoveryClient.

[Note]Note

@EnableDiscoveryClient is no longer required. You can put a DiscoveryClient implementation on the classpath to cause the Spring Boot application to register with the service discovery server.

2.1.1 Health Indicator

Commons creates a Spring Boot HealthIndicator that DiscoveryClient implementations can participate in by implementing DiscoveryHealthIndicator. To disable the composite HealthIndicator, set spring.cloud.discovery.client.composite-indicator.enabled=false. @@ -165,7 +165,7 @@ To access the load-balanced RestTemplate, use the < } public String doStuff() { - return restTemplate.getForObject("http://example.com", String.class); + return restTemplate.getForObject("https://example.com", String.class); } }

If you see errors such as java.lang.IllegalArgumentException: Can not set org.springframework.web.client.RestTemplate field com.my.app.Foo.restTemplate to com.sun.proxy.$Proxy89, try injecting RestOperations or setting spring.aop.proxyTargetClass=true.

 Thus, you can use encrypted values in the form of {cipher}* and, as long as there is a valid key, they are decrypted before the main application context gets the Environment settings.
 To use the encryption features in an application, you need to include Spring Security RSA in your classpath (Maven co-ordinates: "org.springframework.security:spring-security-rsa"), and you also need the full strength JCE extensions in your JVM.

Many of those features are covered by Spring Boot, on which Spring Cloud builds. Some more features are delivered by Spring Cloud as two libraries: Spring Cloud Context and Spring Cloud Commons. Spring Cloud Context provides utilities and special services for the ApplicationContext of a Spring Cloud application (bootstrap context, encryption, refresh scope, and environment endpoints). Spring Cloud Commons is a set of abstractions and common classes used in different Spring Cloud implementations (such as Spring Cloud Netflix and Spring Cloud Consul).

1. Spring Cloud Context: Application Context Services

Spring Boot has an opinionated view of how to build an application with Spring. For instance, it has conventional locations for common configuration files and has endpoints for common management and monitoring tasks. Spring Cloud builds on top of that and adds a few features that probably all components in a system would use or occasionally need.

1.1 The Bootstrap Application Context

A Spring Cloud application operates by creating a “bootstrap” context, which is a parent context for the main application. @@ -96,11 +96,11 @@ In that case, it is rebuilt on a refresh and its dependencies are re-injected. A It follows the same rules as the Config Server and has the same external configuration through encrypt.*. Thus, you can use encrypted values in the form of {cipher}* and, as long as there is a valid key, they are decrypted before the main application context gets the Environment settings. To use the encryption features in an application, you need to include Spring Security RSA in your classpath (Maven co-ordinates: "org.springframework.security:spring-security-rsa"), and you also need the full strength JCE extensions in your JVM.

1.11 Endpoints

For a Spring Boot Actuator application, some additional management endpoints are available. You can use:

  • POST to /actuator/env to update the Environment and rebind @ConfigurationProperties and log levels.
  • /actuator/refresh to re-load the boot strap context and refresh the @RefreshScope beans.
  • /actuator/restart to close the ApplicationContext and restart it (disabled by default).
  • /actuator/pause and /actuator/resume for calling the Lifecycle methods (stop() and start() on the ApplicationContext).

[Note]Note

If you disable the /actuator/restart endpoint then the /actuator/pause and /actuator/resume endpoints will also be disabled since they are just a special case of /actuator/restart.

2. Spring Cloud Commons: Common Abstractions

Patterns such as service discovery, load balancing, and circuit breakers lend themselves to a common abstraction layer that can be consumed by all Spring Cloud clients, independent of the implementation (for example, discovery with Eureka or Consul).

2.1 @EnableDiscoveryClient

Spring Cloud Commons provides the @EnableDiscoveryClient annotation. This looks for implementations of the DiscoveryClient interface with META-INF/spring.factories. Implementations of the Discovery Client add a configuration class to spring.factories under the org.springframework.cloud.client.discovery.EnableDiscoveryClient key. -Examples of DiscoveryClient implementations include Spring Cloud Netflix Eureka, Spring Cloud Consul Discovery, and Spring Cloud Zookeeper Discovery.

By default, implementations of DiscoveryClient auto-register the local Spring Boot server with the remote discovery server. +Examples of DiscoveryClient implementations include Spring Cloud Netflix Eureka, Spring Cloud Consul Discovery, and Spring Cloud Zookeeper Discovery.

By default, implementations of DiscoveryClient auto-register the local Spring Boot server with the remote discovery server. This behavior can be disabled by setting autoRegister=false in @EnableDiscoveryClient.

[Note]Note

@EnableDiscoveryClient is no longer required. You can put a DiscoveryClient implementation on the classpath to cause the Spring Boot application to register with the service discovery server.

2.1.1 Health Indicator

Commons creates a Spring Boot HealthIndicator that DiscoveryClient implementations can participate in by implementing DiscoveryHealthIndicator. To disable the composite HealthIndicator, set spring.cloud.discovery.client.composite-indicator.enabled=false. @@ -262,7 +262,7 @@ To access the load-balanced RestTemplate, use the < } public String doStuff() { - return restTemplate.getForObject("http://example.com", String.class); + return restTemplate.getForObject("https://example.com", String.class); } }

If you see errors such as java.lang.IllegalArgumentException: Can not set org.springframework.web.client.RestTemplate field com.my.app.Foo.restTemplate to com.sun.proxy.$Proxy89, try injecting RestOperations or setting spring.aop.proxyTargetClass=true.

2.6 Spring WebFlux WebClient as a Load Balancer Client

WebClient can be configured to use the LoadBalancerClient. LoadBalancerExchangeFilterFunction is auto-configured if spring-webflux is on the classpath. The following example shows how to configure a WebClient to use load balancer:
