I am trying to use elasticache with my application built with Spring 3.0
Can anyone help about the configuration?
Found the solution - the configuration is same as memcached config.
Add the following in pom.xml
<dependency>
<groupId>com.google.code.simple-spring-memcached</groupId>
<artifactId>spring-cache</artifactId>
<version>3.3.0</version>
</dependency>
<dependency>
<groupId>com.google.code.simple-spring-memcached</groupId>
<artifactId>xmemcached-provider</artifactId>
<version>3.3.0</version>
</dependency>
Add the follow in dispatcher-servlet.xml
<bean name="memcacheManager" class="com.google.code.ssm.spring.SSMCacheManager">
<property name="caches">
<set>
<bean class="com.google.code.ssm.spring.SSMCache">
<constructor-arg name="cache" index="0" ref="defaultCache"/>
<!-- 3 days -->
<constructor-arg name="expiration" index="1" value="259200"/>
<!-- #CacheEvict(..., "allEntries" = true) doesn't work -->
<constructor-arg name="allowClear" index="2" value="true"/>
</bean>
</set>
</property>
</bean>
<bean name="defaultCache" class="com.google.code.ssm.CacheFactory">
<property name="cacheName" value="defaultCache"/>
<property name="cacheClientFactory">
<bean name="cacheClientFactory" class="com.google.code.ssm.providers.xmemcached.MemcacheClientFactoryImpl"/>
</property>
<property name="addressProvider">
<bean class="com.google.code.ssm.config.DefaultAddressProvider">
<property name="address" value="xxx.yyy.cache.amazonaws.com:11211"/>
</bean>
</property>
<property name="configuration">

Currently, My system is using Spring-jms 4.1.6 and ActiveMQ 5.2.0
We facing the issue is that when we have stress requests (50000 continuity requests like DDOS), the server is dying.

Important
My 50000 request is sent frequently, I'm using nodejs to send and send the requests without waiting for the response to test the server.
Use Case: I am running a spring application which has orders. I can create plans for these orders. My dev environment/db does not have any orders and they come from a different application (we share the same db). So, Is there a way I can read orders from production database but when I create a plan, it gets saved to dev database?

In my Jetty server config, I am defining the srvPropertyFile which references to the environment.properties file which has the database connection to dev db.
How should I manage my persistence context so that the entity manager used while reading orders and the entity manager used while creating plans connects to different databases?
you have to configure two persistence unit, data source and transaction manager(one for read and other for write) each.
While using entity manager specify the persistence unit like below.
PersistenceUnit(unitName = "x")
EntityManagerFactory entityManagerFactory;

I tried removing the <diskStore path="java.io.tmpdir"/> line in the ehcache, but to no avail.
EDIT
Spring version: 3.2.4.RELEASE
Ehcache version: 4.1.9.Final
According to EhCache documentation, you can turn off usage of disk for a cache by setting the overflowToDisk attribute to false. So you could try :
<defaultCache
maxElementsInMemory="10000"
overflowToDisk="false"
eternal="false"
timeToIdleSeconds="120"
timeToLiveSeconds="120"
diskExpiryThreadIntervalSeconds="120"
statistics="true"
memoryStoreEvictionPolicy="LRU"/>
I am getting the following exception on server startup. I have just one persistence.xml in my project. Any ideas?

using 3.1.2.RELEASE Maven 3.0.4
I just add below configuration to My context file:
<bean
class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" />
<bean id="pum"
class="org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManager">

</list>
</property>
<property name="defaultDataSource" ref="dataSource"></property>
</bean>
On window I put META-INF/persistence.xml under src/java/resources.
Then I import same project to Ubuntu, this problem appeared. And it is fixed after I moved META-INF/persistence.xml to src/main/webapp.
I'm setting up a maven-spring-hibernate-mysql-tomcat environment.
I would like to inject my Entity manager using the #PersistenceContext annotation.
As I understand to do this, I should have PersistenceAnnotationBeanPostProcessor defined in my application context, pointing to my persistence.xml file.
In this case my application context could be looking like this more or less:

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
<property name="dataSource" ref="dataSourceGlobal" />
</bean>
</beans>
My persistence.xml could look like this:
<persistence-unit name="myPU" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<properties>
<property name="hibernate.transaction.flush_before_completion"
value="true" />
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLInnoDBDialect" />
<property name="hibernate.show_sql" value="true" />
</properties>
</persistence-unit>
So now I guess I should be able to inject my entity manager using the #PersistenceContext annotation, at list this is what I get from the documentation. Before I'mm getting to JpaVendorAdapter, my first question would refer the entity manager factory definition:
The following properties:
<property name="persistenceXmlLocation" value="classpath:META-INF/persistence.xml"/>
<property name="persistenceUnitName" value="myPU" />
Are these required to be referred from the entity manager factory? Is it a must?
My second question would be regarding the JpaVendorAdapter, and in my case HibernateJpaVendorAdapter.
If I use HibernateJpaVendorAdapter, do I still need to have a persistence.xml file? Since some of the properties are overlapping. Moreover, do I still need to have PersistenceAnnotationBeanPostProcessor defined, pointing to my persistence.xml file? Can these 2 go together (PersistenceAnnotationBeanPostProcessor and HibernateJpaVendorAdapter)? Should they go together? What is the best practice, assuming I'm avoiding any JDNI style definitions?
Thanks in advance
The combination of data source bean and HibernateJpaVendorAdapter allows you to get rid of persistence.xml with Spring 3.1. Check out this article:
http://www.baeldung.com/2011/12/13/the-persistence-layer-with-spring-3-1-and-jpa/
So the answers:
They are not a must.
No, you don't need to have a persistence.xml.
I am not exactly sure of what use PersistenceAnnotationBeanPostProcessor is.
<context:component-scan base-package="com.demo.dao" />
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean">
<property name="persistenceUnitName" value="hibernate-resourceLocal"/>
</bean>
<tx:annotation-driven/>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
My Spring application context xml looks as simple as this. And it is working.
I don't what the best practice is, but I will keep persistence.xml so that in case I need to expose my service as session bean, it can be easily done.
