After hours of research, I found that spring-db.xml is where the problem occurs. In there there are definitions to connecting for example to com.mchange.v2.c3p0.ComboPooledDataSource, or enviromentProperties. I tried step by step, line by line commenting/uncommeting something from there, and in there is part defined like this:

   <!-- <tx:annotation-driven /> -->
    <tx:annotation-driven transaction-manager="transactionManager" /> 

    <!-- define the SqlSessionFactory -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="typeAliasesPackage" value="hr.test.model" />
    </bean>


    <!-- scan for mappers and let them be autowired -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="hr.test.dao.api.mappers" />
    </bean>

When I comment last bean which is calling configurer, everything passes well (without exception).

What to do to stop getting that exception? Maybe I must write that bean in some other way? (sorry for not giving whole code, I'm restricted for giving it..)

I'm using: Eclipse Mars Java 1.8 Spring 3.1 MyBatis 32 bit Windows

Sheetal Mohan Sharma - can you give an example what could be wrong? How annotations could be wrong.. ? And which annotations could cause the problem? — DarioBB, Dec 23 '15 at 23:19

Above exception didn't show if you comment following line

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="hr.test.dao.api.mappers" />
    </bean>

then i believe you must be missing the mybatis-spring.jar in your project. Pls try including following in your project :-

<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis-spring</artifactId>
    <version>1.2.3</version>
</dependency>
