Chapter 170. JCache Component Available as of Camel version 2.17 The jcache component enables you to perform caching operations using JSR107/JCache as cache implementation. 170.1. URI Format jcache:cacheName[?options] 170.2. URI Options The JCache endpoint is configured using URI syntax: with the following path and query parameters: 170.2.1. Path Parameters (1 parameters): Name Description Default Type cacheName Required The name of the cache String 170.2.2. Query Parameters (22 parameters): Name Description Default Type cacheConfiguration (common) A Configuration for the Cache Configuration cacheConfigurationProperties (common) The Properties for the javax.cache.spi.CachingProvider to create the CacheManager Properties cachingProvider (common) The fully qualified class name of the javax.cache.spi.CachingProvider String configurationUri (common) An implementation specific URI for the CacheManager String managementEnabled (common) Whether management gathering is enabled false boolean readThrough (common) If read-through caching should be used false boolean statisticsEnabled (common) Whether statistics gathering is enabled false boolean storeByValue (common) If cache should use store-by-value or store-by-reference semantics true boolean writeThrough (common) If write-through caching should be used false boolean bridgeErrorHandler (consumer) Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored. false boolean filteredEvents (consumer) Events a consumer should filter. If using filteredEvents option, then eventFilters one will be ignored List oldValueRequired (consumer) if the old value is required for events false boolean synchronous (consumer) if the event listener should block the thread causing the event false boolean eventFilters (consumer) The CacheEntryEventFilter. If using eventFilters option, then filteredEvents one will be ignored List exceptionHandler (consumer) To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored. ExceptionHandler exchangePattern (consumer) Sets the exchange pattern when the consumer creates an exchange. ExchangePattern action (producer) To configure using a cache operation by default. If an operation in the message header, then the operation from the header takes precedence. String cacheLoaderFactory (advanced) The CacheLoader factory Factory cacheWriterFactory (advanced) The CacheWriter factory Factory createCacheIfNotExists (advanced) Configure if a cache need to be created if it does exist or can't be pre-configured. true boolean expiryPolicyFactory (advanced) The ExpiryPolicy factory Factory lookupProviders (advanced) Configure if a camel-cache should try to find implementations of jcache api in runtimes like OSGi. false boolean 170.3. Spring Boot Auto-Configuration The component supports 6 options, which are listed below. Name Description Default Type camel.component.jcache.cache-configuration A Configuration for the Cache. The option is a javax.cache.configuration.Configuration type. String camel.component.jcache.cache-configuration-properties The Properties for the javax.cache.spi.CachingProvider to create the CacheManager. The option is a java.util.Properties type. String camel.component.jcache.caching-provider The fully qualified class name of the javax.cache.spi.CachingProvider String camel.component.jcache.configuration-uri An implementation specific URI for the CacheManager String camel.component.jcache.enabled Enable jcache component true Boolean camel.component.jcache.resolve-property-placeholders Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders. true Boolean The JCache component supports 5 options, which are listed below. Name Description Default Type cachingProvider (common) The fully qualified class name of the javax.cache.spi.CachingProvider String cacheConfiguration (common) A Configuration for the Cache Configuration cacheConfiguration Properties (common) The Properties for the javax.cache.spi.CachingProvider to create the CacheManager Properties configurationUri (common) An implementation specific URI for the CacheManager String resolveProperty Placeholders (advanced) Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders. true boolean
