For config tow datasource, I config tow MapperScannerConfigurer in my .xml:
<bean id="hybirdMapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.XXX.A.hymapper" />
<property name="sqlSessionFactoryBeanName" value="hybirdSqlSessionFactory"/>
</bean>
<bean id="mysqlMapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.XXX.B.mysmapper" />
<property name="sqlSessionFactoryBeanName" value="mysqlSessionFactory"/>
</bean>
<bean id="mysqlSessionFactory" name="mysqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="mysqlDataSource" />
<property name="configLocation" value="classpath:mybatis-config.xml" />
</bean>
<bean id="hybirdSqlSessionFactory" name="hybirdSqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="hybirdDataSource" />
<property name="configLocation" value="classpath:mybatis-config.xml" />
</bean>
But when I run my app, error comes out:
So I find the source code about sqlSessionTemplateBeanName in MapperScannerConfigurer, and it shows:
It seems that my usage is not wrong, so what can I do to sovle this problem when config multi datasource with xml file and where is my mistake?
thx~

We have the following spring configuration to bootstrap our myBatis. Is there any good way to get the connection in our code within a spring transaction?

I'm configuring JMS Transactions in Camel 2.10.4 routes. When I run my app, a javax.persistence.TransactionRequiredException: no transaction in progress is thrown. From my research, I found out that this exception is thrown when no method is marked #Transactional. The relevant sections in my application context XML config file is shown:
<bean id="txMgr" class="org.springframework.jms.connection.JmsTransactionManager">
<property name="connectionFactory" ref="pooledConnectionFactory" />
</bean>
<bean id="REQUIRED" class="org.apache.camel.spring.spi.SpringTransactionPolicy">
<property name="transactionManager" ref="txMgr" />
<property name="propagationBehaviorName" value="PROPAGATION_REQUIRED" />
</bean>
<bean id="pooledConnectionFactory"
class="org.apache.activemq.pool.PooledConnectionFactory" init-method="start" destroy-method="stop">
<property name="maxConnections" value="8" />
<property name="connectionFactory" ref="jmsConnectionFactory" />
</bean>
<bean id="jmsConnectionFactory"
class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL" value="tcp://localhost:61616" />
</bean>
<bean id="activemq" class="org.apache.activemq.camel.component.ActiveMQComponent">
<property name="configuration" ref="jmsConfig" />
</bean>
<bean id="jmsConfig"
class="org.apache.camel.component.jms.JmsConfiguration">
<property name="connectionFactory" ref="pooledConnectionFactory"/>
<property name="transacted" value="true" />
<property name="transactionManager" ref="txMgr" />
<property name="concurrentConsumers" value="3"/>
</bean>
Besides the JMS-specific configuration, I also have JPA configuration, which is shown below:
<bean id="transactionTemplate" class="org.springframework.transaction.support.TransactionTemplate">
<property name="transactionManager">
<bean class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
</property>
</bean>
<bean id="jpaTemplate" class="org.springframework.orm.jpa.JpaTemplate">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean">
<property name="persistenceUnitName" value="fileRecord" />
</bean>
If I disable transactions, the configuration works. When I enable it, however, all the other steps succeeds except the bit where the data is to be inserted into the database (at the JPA endpoint).
Any suggestions on what I need to change or add will be appreciated very much.
And one entityManagerFactory in spring-server.xml.
But i must generate one more entityManager, and i do it with
Persistence.createEntityManagerFactory("myotherpersistenceunitname");
but i get exception
Caused by: net.sf.ehcache.CacheException: Another unnamed CacheManager already exists in the same VM. Please provide unique names for each CacheManager in the config or do one of following:
1. Use one of the CacheManager.create() static factory methods to reuse same CacheManager with same name or create one if necessary
2. Shutdown the earlier cacheManager before creating new one with same name.
The source of the existing CacheManager is: DefaultConfigurationSource [ ehcache.xml or ehcache-failsafe.xml ]

The problem, described here, and fixed in the source is not using the EhCache singleton correctly. The answer depends on which version of spring-context-support AND which version of EhCache you are using. For both, you need to be using EhCache 2.6 or greater:
<dependency>
<groupId>net.sf.ehcache</groupId>
<artifactId>ehcache</artifactId>
<version>2.6.0</version>
</dependency>
Next, determine what to do based on your spring-context-support version:
If using Spring 3.1/3.2
<bean id="ehcache" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"
p:shared="true"
p:config-location="classpath:ehcache.xml"/>
If using Spring 4.x
<bean id="ehcache" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"
p:shared="false"
P:acceptExisting="true"
p:config-location="classpath:ehcache.xml"/>
Try naming both cacheManagers differently in ehcache.xml
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
name="ehCacheManager1">
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
name="ehCacheManager2">
I understand that the ApplicationContext can be annotation based in Spring 3.
Can anybody please share an example , so that I could refer the same.
Thanks in advance,

I have been through the Spring 3 Documentation and understood the #Configuration annotation.
So issue resolved :)
