聲明:我仍然非常新到MyBatis &春天所以請原諒我,如果一些細節下面缺少。如何使用MapperFactoryBean獲取當前會話?
我有一些代碼在MyBatis中使用MapperFactoryBean
來自動管理數據庫事務,而不必在我的Java代碼中創建DAO類。這也意味着當使用這種方法時,用戶不需要編寫任何會話特定的代碼,因爲MyBatis直接處理與數據庫本身進行通信的會話。
問題:所以當上述情況發生時,如果希望獲得當前會話,那麼您如何做到這一點?在Hibernate中,您可以執行getSessionFactory().getCurrentSession()
以獲取當前會話。當MyBatis的MapperFactoryBean
方法用於與數據庫通信時,MyBatis的等效命令是什麼?
這裏是我當前的代碼片段:
的beans.xml:
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.countries.dataaccess" />
</bean>
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
</bean>
<bean id="countriesMapper" class="org.mybatis.spring.mapper.MapperFactoryBean">
<property name="mapperInterface" value="com.countries.dataaccess.CountryMapper" />
<property name="sqlSessionFactory" ref="sqlSessionFactory" />
</bean>
<bean id="countriesFacade" class="com.countries.facade.CountriesFacade" />
com.countries.dataaccess.CountryMapper:
public interface CountryMapper {
public List<CountryOutlineDTO> getAllCountries(List<String> merchantType);
public CountryDetailsDTO getCountryInfo(String countryCode);
//etc ....
}
com.countries .delegate.CountriesServiceDelegate:
public interface CountriesServiceDelegate {
public CountryDetails getCountryDetails(String countryCode, String locale) throws Exception;
public List<CountryDetails> getAllCountryDetails(List<String> merchantTypeList, boolean verbose) throws Exception;
public Health getDBHealth();
}
com.countries.delegate.impl.CountriesServiceDelegateImpl:
public class CountriesServiceDelegateImpl implements CountriesServiceDelegate {
@Autowired
private CountriesFacade countriesFacade;
@Override
public CountryDetails getCountryDetails(String countryCode, String locale) {
//Implementation logic here ...
}
@Override
public List<CountryDetails> getAllCountryDetails(List<String> merchantTypeList, boolean verbose) {
//Implementation logic here ...
}
}
com.countries.facade:
public class CountriesFacade {
@Autowired
@Qualifier("countriesMapper")
private CountryMapper countriesMapper;
public CountryDetails getCountryInfo(String countryCode, String locale) {
//Implementation logic here such as xyz = countriesMapper.getCountryInfo(countryCode);
}
public List<CountryDetails> getAllCountries(List<String> merchantType, boolean verbose) {
//Implementation logic here such as xyz = countriesMapper.getCountryInfo(countryCode);
}
}
