【问题描述】:
免责声明:我对 MyBatis 和 Spring 还是非常新手,所以如果下面缺少一些细节,请原谅我。
我有一些代码在 MyBatis 中使用 MapperFactoryBean 来自动管理数据库事务,而无需在我的 Java 代码中创建 DAO 类。这也意味着当使用这种方法时,用户不需要编写任何特定于会话的代码,因为 MyBatis 直接处理会话以与数据库本身进行通信。
问题: 那么在上述情况下,如果想获得当前的 Session,你会怎么做呢?在 Hibernate 中,您可以通过 getSessionFactory().getCurrentSession() 获取当前会话。当使用 MyBatis 的MapperFactoryBean 方法与数据库通信时,MyBatis 的等效命令是什么?
这是我当前代码的 sn-ps:
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);
}
}
