How to configure 2 databases in MyBatis using MyBatis-Spring - spring

Question

I am trying to configure 2 different datasources in my application as it is required.
My configuration in the AppContext.xml is as follows:
<bean id="dataSourceA" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.ibm.db2.jcc.DB2Driver"/>
<property name="url" value="datasourceAURL"/>
<property name="username" value="aaaa"/>
<property name="password" value="pppp"/>
</bean>
<bean id="dataSourceB" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.ibm.db2.jcc.DB2Driver"/>
<property name="url" value="datasourceBURL"/>
<property name="username" value="bbbb"/>
<property name="password" value="cccc"/>
</bean>
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com/ex/myBatis/mappings" />
</bean>
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSourceA" />
<property name="typeAliasesPackage" value="com.ex.myBatis.entities"/>
</bean>
<bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
<constructor-arg index="0" ref="sqlSessionFactory" />
</bean>
<bean id="sqlSessionFactory1" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="configDataSource" />
<property name="typeAliasesPackage" value="com.ex.myBatis.entities"/>
</bean>
<bean id="sqlSession1" class="org.mybatis.spring.SqlSessionTemplate">
<constructor-arg index="0" ref="sqlSessionFactory1" />
</bean>
<bean id="callService" class="com.ex.myBatis.Service.callService">
<property name="sqlSession" ref="sqlSession1" />
</bean>
But while accessing the bean I am getting the below Exception
org.springframework.beans.factory.BeanCreationException: Error
creating bean with name 'callService': Injection of autowired
dependencies failed; nested exception is
org.springframework.beans.factory.BeanCreationException: Could not
autowire method: public final void
org.mybatis.spring.support.SqlSessionDaoSupport.setSqlSessionTemplate(org.mybatis.spring.SqlSessionTemplate);
nested exception is
org.springframework.beans.factory.NoUniqueBeanDefinitionException: No
qualifying bean of type [org.mybatis.spring.SqlSessionTemplate] is
defined: expected single matching bean but found 2:
sqlSession,sqlSession1
Please somebody help me in figuring out the issue.
Also please suggest me if there is someother way to configure 2 Datasources.

Answer 1

Your configuration is mostly correct. The problem you face is that you use autowiring to inject one of callService dependencies.
Seems that you use SqlSessionDaoSupport and its sqlSessionTemplate field is autowired. There are two templates defined so spring cannot automatically wire dependencies. You need specify correct template manually.
