事务注解

@Service
public class RoleListServiceImpl implements RoleListService {
	
	@Autowired
	private RoleService roleService;
	
	@Override
	@Transactional(propagation=Propagation.REQUIRED, isolation=Isolation.READ_COMMITTED, timeout=3)
	public void insertRole(List<Role> roles) {
		for (Role role : roles) {
			roleService.insertRole(role);
		}
	}
	
}


@Service
public class RoleServiceImpl implements RoleService {
	
	@Autowired
	private RoleMapper dao;
	
	@Override
	@Transactional(propagation=Propagation.REQUIRES_NEW, isolation=Isolation.READ_COMMITTED, timeout=3)
	public void insertRole(Role role) {
		dao.insertRole(role);
	}
	
}

其他重要接口

@Repository在配置文件xml中，指明了dao层注解为Repository

@Repository
public interface RoleMapper {
	
	void insertRole(Role role);

	Role selectRole(int id);
}

测试类

public class TestRun {
	
	private static final Logger logger = LoggerFactory.getLogger(TestRun.class);
	
	public static void main(String[] args) {
		ApplicationContext context = new ClassPathXmlApplicationContext("spring-tx-config.xml");
		RoleListService bean = context.getBean(RoleListService.class);
		
		List<Role> roles = new ArrayList<>();
		Role role = new Role();
		role.setId(10087);
		role.setName("10087");
		role.setDesc("10087");
		roles.add(role);
		role = new Role();
		role.setId(10088);
		role.setName("10088");
		role.setDesc("10088");
		roles.add(role);
		
		bean.insertRole(roles);
		logger.debug(bean.toString());
	}

}
