Class R2dbcMapperScannerConfigurer

java.lang.Object

pro.chenggang.project.reactive.mybatis.support.r2dbc.spring.mapper.R2dbcMapperScannerConfigurer

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 R2dbcMapperScannerConfigurer
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 ReactiveSqlSessionFactory or SqlSessionTemplate. If there is more than one ReactiveSqlSessionFactory in the application, however, autowiring cannot be used. In this case you must explicitly specify either an ReactiveSqlSessionFactory 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.

Method Detail

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

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

setSqlSessionFactoryBeanName

public void setSqlSessionFactoryBeanName(String sqlSessionFactoryName)

Specifies which ReactiveSqlSessionFactory 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 ReactiveSqlSessionFactory

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

setMapperFactoryBeanClass

public void setMapperFactoryBeanClass(Class<? extends R2dbcMapperFactoryBean> mapperFactoryBeanClass)

The class of the MapperFactoryBean to return a mybatis proxy as spring bean.

Parameters:

mapperFactoryBeanClass - The class of the MapperFactoryBean

Since:

2.0.1

setApplicationContext

public void setApplicationContext(org.springframework.context.ApplicationContext applicationContext)

Specified by:

setApplicationContext in interface org.springframework.context.ApplicationContextAware

setBeanName

public void setBeanName(String name)

Specified by:

setBeanName in interface org.springframework.beans.factory.BeanNameAware

getNameGenerator

public org.springframework.beans.factory.support.BeanNameGenerator getNameGenerator()

Gets beanNameGenerator to be used while running the scanner.

Returns:

the beanNameGenerator that has been configured

Since:

1.2.0

setNameGenerator

public void setNameGenerator(org.springframework.beans.factory.support.BeanNameGenerator nameGenerator)

Sets beanNameGenerator to be used while running the scanner.

Parameters:

nameGenerator - the beanNameGenerator to set

Since:

1.2.0

setDefaultScope

public void setDefaultScope(String defaultScope)

Sets the default scope of scanned mappers.

Default is null (equiv to singleton).

Parameters:

defaultScope - the default scope

Since:

2.0.6

afterPropertiesSet

                        throws Exception

postProcessBeanDefinitionRegistry

public void postProcessBeanDefinitionRegistry(org.springframework.beans.factory.support.BeanDefinitionRegistry registry)

Specified by:

postProcessBeanDefinitionRegistry in interface org.springframework.beans.factory.support.BeanDefinitionRegistryPostProcessor
