Package org.mybatis.spring.mapper

Class MapperScannerConfigurer

java.lang.Object
org.mybatis.spring.mapper.MapperScannerConfigurer
All Implemented Interfaces:
org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanNameAware, org.springframework.beans.factory.config.BeanFactoryPostProcessor, org.springframework.beans.factory.InitializingBean, org.springframework.beans.factory.support.BeanDefinitionRegistryPostProcessor, org.springframework.context.ApplicationContextAware
public class MapperScannerConfigurer extends Object implements org.springframework.beans.factory.support.BeanDefinitionRegistryPostProcessor, org.springframework.beans.factory.InitializingBean, org.springframework.context.ApplicationContextAware, org.springframework.beans.factory.BeanNameAware
BeanDefinitionRegistryPostProcessor that searches recursively starting from a base package for interfaces and registers them as MapperFactoryBean. Note that only interfaces with at least one method will be registered; concrete classes will be ignored.

This class was a {code BeanFactoryPostProcessor} until 1.0.1 version. It changed to BeanDefinitionRegistryPostProcessor in 1.0.2. See https://jira.springsource.org/browse/SPR-8269 for the details.

The basePackage property can contain more than one package name, separated by either commas or semicolons.

This class supports filtering the mappers created by either specifying a marker interface or an annotation. The annotationClass property specifies an annotation to search for. The markerInterface property specifies a parent interface to search for. If both properties are specified, mappers are added for interfaces that match either criteria. By default, these two properties are null, so all interfaces in the given basePackage are added as mappers.

This configurer enables autowire for all the beans that it creates so that they are automatically autowired with the proper SqlSessionFactory or SqlSessionTemplate. If there is more than one SqlSessionFactory in the application, however, autowiring cannot be used. In this case you must explicitly specify either an SqlSessionFactory or an SqlSessionTemplate to use via the bean name properties. Bean names are used rather than actual objects because Spring does not initialize property placeholders until after this class is processed.

Passing in an actual object which may require placeholders (i.e. DB user password) will fail. Using bean names defers actual object creation until later in the startup process, after all placeholder substitution is completed. However, note that this configurer does support property placeholders of its own properties. The basePackage and bean name properties all support ${property} style substitution.

Configuration sample: 

 
   <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
       <property name="basePackage" value="org.mybatis.spring.sample.mapper" />
       <!-- optional unless there are multiple session factories defined -->
       <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
   </bean>

    • setBasePackage

      public void setBasePackage(String basePackage)
      This property lets you set the base package for your mapper interface files.

      You can set more than one package by using a semicolon or comma as a separator.

      Mappers will be searched for recursively starting in the specified package(s).

      Parameters:
      basePackage - base package name

    • setAddToConfig

      public void setAddToConfig(boolean addToConfig)
      Same as MapperFactoryBean#setAddToConfig(boolean).
      Parameters:
      addToConfig - a flag that whether add mapper to MyBatis or not
      See Also:

    • setLazyInitialization

      public void setLazyInitialization(String lazyInitialization)
      Set whether enable lazy initialization for mapper bean.

      Default is false.

      Parameters:
      lazyInitialization - Set the @{code true} to enable
      Since:
      2.0.2

    • setAnnotationClass

      public void setAnnotationClass(Class<? extends Annotation> annotationClass)
      This property specifies the annotation that the scanner will search for.

      The scanner will register all interfaces in the base package that also have the specified annotation.

      Note this can be combined with markerInterface.

      Parameters:
      annotationClass - annotation class

    • setMarkerInterface

      public void setMarkerInterface(Class<?> superClass)
      This property specifies the parent that the scanner will search for.

      The scanner will register all interfaces in the base package that also have the specified interface class as a parent.

      Note this can be combined with annotationClass.

      Parameters:
      superClass - parent class

    • setSqlSessionTemplate

      @Deprecated public void setSqlSessionTemplate(SqlSessionTemplate sqlSessionTemplate)
      Deprecated.
      Use setSqlSessionTemplateBeanName(String) instead
      Specifies which SqlSessionTemplate to use in the case that there is more than one in the spring context. Usually this is only needed when you have more than one datasource.

      Parameters:
      sqlSessionTemplate - a template of SqlSession

    • setSqlSessionTemplateBeanName

      public void setSqlSessionTemplateBeanName(String sqlSessionTemplateName)
      Specifies which SqlSessionTemplate to use in the case that there is more than one in the spring context. Usually this is only needed when you have more than one datasource.

      Note bean names are used, not bean references. This is because the scanner loads early during the start process and it is too early to build mybatis object instances.

      Parameters:
      sqlSessionTemplateName - Bean name of the SqlSessionTemplate
      Since:
      1.1.0

    • setSqlSessionFactory

      @Deprecated public void setSqlSessionFactory(org.apache.ibatis.session.SqlSessionFactory sqlSessionFactory)
      Deprecated.
      Use setSqlSessionFactoryBeanName(String) instead.
      Specifies which SqlSessionFactory to use in the case that there is more than one in the spring context. Usually this is only needed when you have more than one datasource.

      Parameters:
      sqlSessionFactory - a factory of SqlSession

    • setSqlSessionFactoryBeanName

      public void setSqlSessionFactoryBeanName(String sqlSessionFactoryName)
      Specifies which SqlSessionFactory to use in the case that there is more than one in the spring context. Usually this is only needed when you have more than one datasource.

      Note bean names are used, not bean references. This is because the scanner loads early during the start process and it is too early to build mybatis object instances.

      Parameters:
      sqlSessionFactoryName - Bean name of the SqlSessionFactory
      Since:
      1.1.0

    • setProcessPropertyPlaceHolders

      public void setProcessPropertyPlaceHolders(boolean processPropertyPlaceHolders)
      Specifies a flag that whether execute a property placeholder processing or not.

      The default is false. This means that a property placeholder processing does not execute.

      Parameters:
      processPropertyPlaceHolders - a flag that whether execute a property placeholder processing or not
      Since:
      1.1.1
