If you need configure different expire time for cache when using @cacheable , you can configure different CacheManager with different ttl,and specify cacheManager when using cache in your service.
I have a library jar which I want to provide to a number of applications. The behavior I want is to create a common spring component class in the library. If in the applications, the same component is not extended then use the common component; if it's extended in the app, then use the extended component (child class). Is this possible? - Create CommonComponent only if a child for that class doesn't exist.

Indeed, in the latest version of Spring Data, findOne returns an optional. If you want to retrieve the object from the Optional, you can simply use get() on the Optional. First of all though, a repository should return the optional to a service, which then handles the case in which the optional is empty. afterwards, the service should return the object to the controller.

I'm trying to upgrade spring boot from 1.5 to 2.0 and facing issue with jetty version. I'm new to neo4j ogm and spring boot.
When I try to run a test case it fails with below error....
ANSWERAnswered 2018-Jul-04 at 11:44
I tried reaching Neo4j team and here is the response I received.
The root problem is the dependency mismatch between SpringBoot and Neo4j on jetty. The problem occurs because you are using the
MultiDriverTestClass from the neo4j-ogm-test module.
It will spawn a Neo4j instance that will take request over the given transport mode defined via the protocol you defined in your
If you would alter your test base to an embedded instance, you could work around the problem:
MultiDriverTestClass inheritance and create a
Configuration on your own like
Configuration configuration = new Configuration.Builder(new ClasspathConfigurationSource("ogm.properties")).build();. The content of the
ogm.properties should be empty to force OGM to create a new temporary embedded instance.
I am using
EHcache, but I am not sure if
sync=true is supported?
How to check it?...
ANSWERAnswered 2018-Jun-14 at 06:39
@Cacheable allows you to specify the
sync attribute to ensure only a single thread is building the cache value.
How to check:
Access the cached data by sending the two parallel request and modify the data. The second thread should get only updated value.

You can use SpringBoot2.0 like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the SpringBoot2.0 component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
