Spring MyBatis expected at least 1 bean which qualifies as autowire candidate for this dependency - spring

Question

i have a trouble with my Spring MyBatis Project.
Here the classes of the 4 packages tiers:
controller
mapper
model
service
com.mb.alf.controller
ServizioController.java
package com.mb.alf.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.SessionAttributes;
import org.springframework.web.servlet.ModelAndView;
import com.mb.alf.model.Servizio;
import com.mb.alf.service.ServizioService;
#Controller
#SessionAttributes("servizio")
public class ServizioController {
#Autowired
private ServizioService servizioService;
#RequestMapping("/returnServizio")
public ModelAndView returnServizio() {
Servizio servizio = servizioService.getServizio();
return new ModelAndView("returnServizio", "servizio", servizio); }}
com.mb.alf.mapper
ServizioMapper.java
package com.mb.alf.mapper;
import org.apache.ibatis.annotations.Select;
import com.mb.alf.model.Servizio;
public interface ServizioMapper {
#Select("select s.ser_puntopresa, s.ser_oldcodser from serviz s where s.ser_ute = '01' and S.SER_PUNTOPRESA = 101")
public Servizio getServizio();
}
com.mb.alf.model
Servizio.java
package com.mb.alf.model;
public class Servizio {
Integer serv_puntopresa;
Integer ser_oldcodser;
public Integer getSer_oldcodser() {
return ser_oldcodser; }
public void setSer_oldcodser(Integer ser_oldcodser) {
this.ser_oldcodser = ser_oldcodser; }
public Integer getServ_puntopresa() {
return serv_puntopresa; }
public void setServ_puntopresa(Integer num) {
this.serv_puntopresa = num; }
}
com.mb.alf.service
ServizioService.java
package com.mb.alf.service;
import com.mb.alf.model.Servizio;
public interface ServizioService {
Servizio getServizio();
}
ServizioServiceImpl.java
package com.mb.alf.service;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.mb.alf.mapper.ServizioMapper;
import com.mb.alf.model.Servizio;
#Component #Service("servizioService")
public class ServizioServiceImpl implements ServizioService {
#Autowired
private ServizioMapper servizioMapper;
#Transactional
public Servizio getServizio() {
return servizioMapper.getServizio(); } }
Here my XML files:

</bean>
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

</bean>
</beans>
It gets this Exception:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'servizioController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.mb.alf.service.ServizioService com.mb.alf.controller.ServizioController.servizioService; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'servizioService': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.mb.alf.mapper.ServizioMapper com.mb.alf.service.ServizioServiceImpl.servizioMapper; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.mb.alf.mapper.ServizioMapper] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)}
Please, how and where can I implement the correct bean?
Thanks in advance

Answer 1

Perhaps you should seperate the mybatis setup in another xml instead of putting it in current springConfig.xml
For example:
web.xml add the following:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:conf/spring.xml;
classpath:conf/spring-mybatis.xml
</param-value>
</context-param>
...
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
In spring-mybatis.xml*, add your dataSource, transactionManager, sqlSessionFactory, sqlSession and org.mybatis.spring.mapper.MapperScannerConfigurer.
