service接口

xml配置了insert*拦截器，这些方法会把事务代理

@Service
public class RoleXmlServiceImpl implements RoleXmlService {
	
	@Autowired
	private RoleMapper dao;
	
	// 方法名上没有注解
	@Override
	public void insertRole(Role role) {
		dao.insertRole(role);
	}
	
}

测试类

// xml事务
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());
	}
}
