Camel Spring Boot Starter for caffeine

Spring Boot Auto-Configuration

When using caffeine with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-caffeine-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

The component supports 38 options, which are listed below.

Name Description Default Type

camel.component.caffeine-cache.action

To configure the default cache action. If an action is set in the message header, then the operation from the header takes precedence.

String

camel.component.caffeine-cache.basic-property-binding

Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

Boolean

camel.component.caffeine-cache.cache

To configure an already instantiated cache to be used. The option is a com.github.benmanes.caffeine.cache.Cache type.

String

camel.component.caffeine-cache.cache-loader

To configure a CacheLoader in case of a LoadCache use. The option is a com.github.benmanes.caffeine.cache.CacheLoader type.

String

camel.component.caffeine-cache.configuration

Sets the global component configuration. The option is a org.apache.camel.component.caffeine.CaffeineConfiguration type.

String

camel.component.caffeine-cache.create-cache-if-not-exist

Configure if a cache need to be created if it does exist or can’t be pre-configured.

true

Boolean

camel.component.caffeine-cache.enabled

Whether to enable auto configuration of the caffeine-cache component. This is enabled by default.

Boolean

camel.component.caffeine-cache.eviction-type

Set the eviction Type for this cache

EvictionType

camel.component.caffeine-cache.expire-after-access-time

Set the expire After Access Time in case of time based Eviction (in seconds)

300

Integer

camel.component.caffeine-cache.expire-after-write-time

Set the expire After Access Write in case of time based Eviction (in seconds)

300

Integer

camel.component.caffeine-cache.initial-capacity

Set the initial Capacity for the cache

10000

Integer

camel.component.caffeine-cache.key

To configure the default action key. If a key is set in the message header, then the key from the header takes precedence. The option is a java.lang.Object type.

String

String

camel.component.caffeine-cache.lazy-start-producer

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

Boolean

camel.component.caffeine-cache.maximum-size

Set the maximum size for the cache

10000

Integer
