@Configuration

public class SqlSessionFactoryBackMaster {

@Bean(name = "backMaster")

public HikariDataSource backMaster() {
return DataSourceBuilder.create().type(HikariDataSource.class).build();
}

@Bean(name = "backMasterSqlSessionFactory")
public SqlSessionFactory backMasterSqlSessionFactory(
@Qualifier("backMaster") DataSource backMaster) throws Exception {
SqlSessionFactoryBean factoryBean = new SqlSessionFactoryBean();
factoryBean.setDataSource(backMaster);
factoryBean.setMapperLocations(new PathMatchingResourcePatternResolver()
.getResources("classpath:org/com/dao/backMaster/*.xml"));
factoryBean.setConfigLocation(
new DefaultResourceLoader().getResource("classpath:mybatis-config.xml"));
return factoryBean.getObject();
}

@Bean(name = "backMasterTransactionManager")
public DataSourceTransactionManager backMasterTransactionManager() {
return new DataSourceTransactionManager(backMaster());
}

@Bean(name = "backMasterSqlSessionTemplate")
public SqlSessionTemplate backMasterSqlSessionTemplate() throws Exception {
SqlSessionTemplate template = new SqlSessionTemplate(
backMasterSqlSessionFactory(backMaster()));
return template;
}
}
