Spring整合

整合MyBatis

• SqlSessionFactoryBean

public class MyBatisConfig {

    @Bean
    public SqlSessionFactoryBean sqlSessionFactory(DataSource dataSource){
        SqlSessionFactoryBean ssfb = new SqlSessionFactoryBean();
        ssfb.setTypeAliasesPackage("com.itheima.domain");
        ssfb.setDataSource(dataSource);
        return ssfb;
    }
}

• MapperScannerConfigurer

public class MyBatisConfig {
    @Bean
    public MapperScannerConfigurer mapperScannerConfigurer(){
        MapperScannerConfigurer msc = new MapperScannerConfigurer();
        msc.setBasePackage("com.itheima.dao");
        return msc;
    }
}

整合Junit

• 使用Spring整合Junit专用的类加载器

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = SpringConfig.class)
public class AccountServiceTest {

    @Autowired
    private AccountService accountService;

    @Test
    public void testFindById(){
        System.out.println(accountService.findById(1));
    }

    @Test
    public void testFindAll(){
        System.out.println(accountService.findAll());
    }

}
