I have a problem setting up a jcache with spring cache abstraction.
#Configuration
#EnableCaching
public class CacheConfig {
#Bean(name = "caffeineCachingProvider")
public CachingProvider caffeineCachingProvider() {
return new CaffeineCachingProvider();
}
#Bean(name = "caffeineCacheManager")
public JCacheCacheManager getSpringCacheManager() {
CacheManager cacheManager = caffeineCachingProvider().getCacheManager();
CaffeineConfiguration<String, List<Product>> caffeineConfiguration = new CaffeineConfiguration<>();
caffeineConfiguration.setExpiryPolicyFactory(FactoryBuilder.factoryOf(new AccessedExpiryPolicy(new Duration(TimeUnit.MINUTES, 60))));
Cache<String, List<Product>> productCache = cacheManager.createCache("productCache", caffeineConfiguration);
JCacheCacheManager jCacheCacheManager = new JCacheCacheManager(cacheManager);
return jCacheCacheManager;
}
}
I'm using Caffein as Jcache. I just cannot understand what i'm doing wrong. Would you explain how to do it properly?
What i'm getting is NPE at line cacheManager.createCache(...)
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'caffeineCacheManager' defined in com.myapp.spring.config.CacheConfig: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.cache.jcache.JCacheCacheManager]: Factory method 'getSpringCacheManager' threw exception; nested exception is java.lang.NullPointerException

Read more about Caffeine configuration. Its JCache adapter uses default specification (JCache) settings which states that entries never expires and are stored by value (copied when put/retrieved from cache). (reference here).
When cache is set to copying instances, you should choose adequate Copier which will handle that. So you can just write:
caffeineConfiguration.setCopierFactory(JavaSerializationCopier::new);
or
caffeineConfiguration.setCopierFactory(Copier::identity);
It depends on if you want to be safe in case of cache key/value mutations.
Nevertheless, the recommended option is to use default settings where store-by-value option is disabled and copier is necessary:
Config config = ConfigFactory.load();
CaffeineConfiguration<String, List<Product>> caffeineConfiguration = TypesafeConfigurator.defaults(config);
caffeineConfiguration.setExpiryPolicyFactory(factoryOf(new AccessedExpiryPolicy(new Duration(
TimeUnit.MINUTES, 60))));
Alternatively, you can just disable store-by-value setting by:
caffeineConfiguration.setStoreByValue(false);

I am trying to run a spring boot project as standalone that was originally developed for WAR deployment in a tomcat and uses older spring boot versions.
I was able to write my main class that starts the application and I can see that its doing all startup activities that is done by original application but that I am stuck at below error that is thrown towards the very end.

A quick solution or workaround will be highly appreciated.
You can add static servlet entry in webmvc-config.xml of spring application.
Given link has reference on how to set default servlet to refer at path /.

The injection of my sessionFacotry bean into my transactionManager bean failed. It seems that the sessionFactory bean type (i.e. LocalSessionFactoryBean) is not recognized as SessionFactory type by the container, and therefore it is not injected into the transactionManager bean.
My configuration class :

#Autowired

#Bean(name="dataSource")

dataSource.setDriverClass(env.getProperty("db.driverClass"));
dataSource.setJdbcUrl(env.getProperty("db.jdbcUrl"));
dataSource.setUser(env.getProperty("db.user"));
dataSource.setPassword(env.getProperty("db.password"));
dataSource.setMaxPoolSize(50);
dataSource.setMinPoolSize(5);
dataSource.setMaxConnectionAge(1800);
dataSource.setMaxIdleTime(1800);
dataSource.setAutoCommitOnClose(false);
dataSource.setInitialPoolSize(5);
return dataSource;
}
#Bean(name="sessionFactory")
#Scope("singleton")
public LocalSessionFactoryBean getSessionFactory(javax.sql.DataSource dataSource){
LocalSessionFactoryBean localSessionFactoryBean = new LocalSessionFactoryBean();

Thanks in advance!
I see you have a reliance on snapshot versioning in your pom.xml .This means you will pull any recent releases which may not be fully bug free. If you look in your error message you will see
spring-boot-1.4.0.BUILD-20160727.140415-585.jar:1.4.0.BUILD-SNAPSHOT
This is a version built today which might not be fully stable. Instead change your pom to use the current general availability version for stability
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>

I have troubles deploying my grails3 application to a tomcat7 server. In the local development environment (bundled tomcat-server) everything works well. The code compiles and runs.
Then I use grails clean and grails war to create war which I deployed to a tomcat7-instance. While starting tomcat it crashes with the following error:
ERROR org.springframework.boot.SpringApplication - Application startup failed

The problem seems to be that the classloader could not find my spring-security role-domain EwsOhElemeter.Role which is definitely present. Also it works in my local environment.
Maybe its a classpath problem or some of the classes do not get compiled into the war file.
Steps I tried:
- Changed integrated tomcat-instance from "compile" to "provided"
- Cleaned build and grandle folders
- A lot of grails clean
I found a solution: It seemed to be a problem with the package name. It contained some capital characters. Spring security seems to have problems with case sensitive package names. I converted all of them to lower case and tada: It works!
Thanks for the solution
I want to inject a session scoped event bus into a Spring service in a Vaadin project with Spring Boot.
My Service looks as follows:
#Service
#EnableVaadinEventBus
public class MyService implements EventBusListener<Object> {
#Autowired
EventBus.SessionEventBus eventBus;
#PostConstruct
void init() {
eventBus.subscribe(this);
}
void myServiceMethod() {
....
}
#Override
public void onEvent(Event<Object> event) {}
}
The MyService class is autowired into a view annotated with #SpringComponent and #SpringView(name = MyView.VIEW_NAME).
When I start my application I get the exception

I guess that the reason for this error is, that the service is singleton and eventbus is session scoped.
Is a proxy the resolution for this problem? If so, how could I create on for my eventbus?
UPDATE
When using the #EventBusProxy annotation I get a different error, which shows, that the eventBus is proxied:

Do I need a proxy for myService? This bean should still be singleton, shouldn't it??
