Important this will only reduce the endpoint cache of the toD that has a chance of being reused in case a message is routed with the same userName header. Therefore reducing the cache size will not solve the endless dynamic endpoints problem. Instead you should use static endpoints with to and provide the dynamic parts in Camel message headers (if possible).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.The org.springframework.batch.core.JobExecution instance produced by the Spring Batch is sent as a body of the message. To distinguish between before- and after-callbacks SPRING_BATCH_JOB_EVENT_TYPE header is set to the BEFORE or AFTER value. Spring allows fine-grained control for declaring timeouts for particular requests, but you can define them globally by setting a property spring.mvc.async.request-timeout.

In our example, we'll use a CaffeineCacheManager and a simple ConcurrentMapCacheManager. CaffeineCacheManager is provided by the spring-boot-starter-cache starter. It'll be auto-configured by Spring if Caffeine is present, which is a caching library written in Java 8.You need not explicitly set the Content-Type header of the request. In most cases, you can find a compatible message converter based on the source Object type, and the chosen message converter sets the content type accordingly. If necessary, you can use the exchange methods to explicitly provide the Content-Type request header, and that, in turn, influences what message converter is selected.Spring provides a few implementations of that abstraction: JDK java.util.concurrent.ConcurrentMap based caches, Ehcache 2.x, Gemfire cache, Caffeine, and JSR-107 compliant caches (such as Ehcache 3.x).

AspectJ를 이용하면 ...I believe Spring Cache by default is non-blocking by using cache.getIfPresent(key) and cache.put(key). If you use sync = true in its cache annotation then it will use a blocking cache.get(key, mappingFunction). You can do the same in your code. It is generally preferable to compute through the cache to avoid stampedes. That isn't always possible, e.g. recursive computations are not supported and have to be side loaded. This reduces memory usage as otherwise producers/endpoints are stored in memory in the caches. However if there are a high degree of dynamic endpoints that have been used before, then it can benefit to use the cache to reuse both producers and endpoints and therefore the cache size can be set accordingly or rely on the default size (1000).
