service介面
xml配置了insert*
攔截器,這些方法會把事務代理
@Service
public class RoleXmlServiceImpl implements RoleXmlService {
@Autowired
private RoleMapper dao;
// 方法名上沒有註解
@Override
public void insertRole(Role role) {
dao.insertRole(role);
}
}
測試類
// xml事務 private static final Logger logger = LoggerFactory.getLogger(TestMapperScanner.class); public static void main(String[] args) { ApplicationContext context = new ClassPathXmlApplicationContext("spring-tx-xml.xml"); RoleXmlService bean = context.getBean(RoleXmlService.class); Role role = new Role(); role.setId(10089); role.setName("10089"); role.setDesc("10089"); bean.insertRole(role); logger.debug(bean.toString()); } }
