How to have spring cache store the ResponseBody and not the intermediary object

由 白昼怎懂夜的黑 提交于 2019-12-10 01:42:45
问题 I use spring cache with this method which returns the queried value as JSON: @RequestMapping("/getById") @ResponseBody @Cacheable public HugeValue getHugeValueFromSlowFoo( @RequestParam(value = "id", defaultValue = "") String id ) { return Foo.getById( id ); } This works fine and the HugeValue-object is stored in the cache (Hazelcast in this case). I want to further improve this because the time taken to create JSON from the HugeValue is quite high. Can I tell spring cache to cache the JSON

after upgrade to Spring Boot 2, how to expose cache metrics to prometheus?

由 独自空忆成欢 提交于 2019-12-07 06:40:13
问题 I recently upgraded a spring boot application from 1.5 to 2.0.1. I also migrated the prometheus integration to the new actuator approach using micrometer. Most things work now - including some custom counters and gauges. I noted the new prometheus endpoint /actuator/prometheus does no longer publish the spring cache metrics (size and hit ratio). The only thing I could find was this issue and its related commit. Still I can't get cache metrics on the prometheus export. I tried settings some

由 北战南征 提交于 2019-12-06 07:58:00
问题 I generally use the @Cacheable with a cache config in my spring-boot app and set specific TTL (time to live) for each cache. I recently inherited a spring boot app that uses @Cacheable without explicitly stating a cache manager and ttl. I will be changing it to be explicit. But I am not able to find out what are the defaults when there is nothing explicit. I did look at the docs but found nothing there 回答1: With spring boot, I was able to achieve success with this: First, you need to add
