how to scan multiple packages with MapperScannerConfigurer with spring3, mybatis, and mybatis-spring

[Randy P]

I am re factoring an existing application to spring3 and mybatis-spring.

One of my restrictions is to keep the current package layout.

it seems that when using org.mybatis.spring.mapper.MapperScannerConfigurer or  <mybatis:scan> that is does not recursively look other packages, and i am looking how best to do this. I have it working now by adding individually each DAO interface to the MapperScannerConfigurer

in my applicationContext i have ::

    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

        <property name="dataSource" ref="formularyDb" />

        <property name="configLocation"  value="file:/web/sites/drugformulary-spring/config/mybatis-config.xml" />

        <property name="mapperLocations" value="file:/web/sites/drugformulary-spring/mappers/*.xml" />

    </bean>

    <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">

        <constructor-arg index="0" ref="sqlSessionFactory" />

    </bean>

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

        <property name="basePackage" value="org.mydm.formulary.drugmaster.dao

                                                                 ,org.mydm.formulary.pdfgroup.dao

                                                                 ,org.mydm.formulary.drugconfig.dao

                                                                "

        />

    </bean>

As mentioned i have to add each of these interfaces eg:org.mydm.formulary.pdfgroup.dao manually.

I have tried <property name="basePackage" value="org.mydm.formulary "/>  but none of the dao's where found and I also tried

<mybatis:scan base-package="org.myd.formulary.drugmaster" /> which also did not work, to work the package where the doa is must be specified.

my package structure is like below and i am required to keep it like this

org.mydm.formulary.drugmaster.controller

                                              .service

                                              .dao

org.mydm.formulary.pdfgroup.controller

                                              .service

                                              .dao

org.mydm.formulary.drugconfig.controller

                                              .service

                                              .dao

Randy, the scanner does search recursively you can even point to your root classpath and mark the interfaces with a marker interface or a custom annotation.

Eduardo, thanks for responding. That is what I thought and maybe i am misunderstanding how to do it

for example 

this works::

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

        <property name="basePackage" value="org.mydm.formulary.drugmaster.dao

                                                                 ,org.mydm.formulary.pdfgroup.dao

                                                                 ,org.mydm.formulary.drugconfig.dao

                                                                   "

        />

    </bean>

this does not work should it?

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

        <property name="basePackage" value="org.mydm.formulary"/>

    </bean>

 

I get the exception when i try to access one of them

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): org.mydm.formulary.drugmaster.service.DrugMasterService.getDrugsWithAlert

[Eduardo Macarron]

It should indeed. 

And also an expression like **.dao

This worked!!!!

Thankyou SO MUCH!

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

        <property name="basePackage" value="org.mydm.formulary.**.dao"/>

    </bean>
