Manual and Annotation based myBatis-Spring Configuration

Here are two essentially same examples of configuring myBatis-Spring with annotations or using manual configuration, using a custom maven modules.  You can look at the details on github (https://github.com/cherryshoe/cherryshoe-examples/tree/master/mybatis-spring), but the highlights are called out below.

Directory Structure

/*-custom-database     <-- Maven pom.xml

  /src

    /main/

      /java                   <-- Java code

        /com/

          /cherryshoe

            /database

                          /dao            <-- Dao logic

              /domain         <-- Business domain objects

              /persistence    <-- Mapper interfaces

      /resources              <-- Non java files

        /com

          /cherryshoe

            /database

              /persistence    <-- Mapper XML files

                /spring               <-- Spring files

    /test/

      /java                   <-- Java code

        /com/

          /cherryshoe

            /database

                          /dao            <-- Dao logic tests

      /resources              <-- Non java files

        /database             <-- Sql in memory files (H2)

        /spring               <-- Spring test files

Differences with the manual configuration method:
LogsDao.java

• No @Service for LogsDao class
• No @Autowired for LogsMapper
• Add in setter method for LogsMapper

  public void setVwDocManCtsMapper(VwDocManCtsMapper vwDocManCtsMapper) {
      this.vwDocManCtsMapper = vwDocManCtsMapper;
  }
  

spring-custom-database.xml and spring-custom-database-test.xml

• No <context:component-scan> to enable component scanning
• No <context:annotation-config> to enable use of autowiring
• No org.mybatis.spring.mapper.MapperScannerConfigurer to scan for mappers and let them be autowired
• Add in spring beans for the LogsMapper and LogsDao classes.  These can then also be used when importing this module into another maven module.

  <bean id="logsMapper" class="org.mybatis.spring.mapper.MapperFactoryBean">
    <property name="mapperInterface" value="com.cherryshoe.database.persistence.LogsMapper" />
    <property name="sqlSessionFactory" ref="sqlSessionFactory" />
  </bean>
  
  <bean id="logsDao" class="com.cherryshoe.database.dao.LogsDao" >
      <property name="logsMapper" ref="logsMapper" />
  </bean>
