spring 事物管理的bug

public class DayAtmRunHistory implements IBOTask {
	
	@Autowired
	private DayAtmRunHistoryService dayAtmRunHistoryService;
	private static final Logger logger=LoggerFactory
	.getLogger(DayAtmRunHistory.class);
	/* (non-Javadoc)
	 * @see boframework.IBOTask#process(boframework.IBOTaskRecorder, java.lang.String[], boframework.data.TaskTrace)
	 */
	@Override
	public void process(IBOTaskRecorder recoder, String[] parms, TaskTrace taskTrace)
			throws Exception {
		//dayAtmRunHistoryService.service(recoder, parms, taskTrace);
		logger.info("DayAtmRunHistory entry!");
		System.out.println(taskTrace==null);
		if(!dayAtmRunHistoryService.initData(recoder, parms, taskTrace)){
			String info="数据初始化校验失败！";
			dayAtmRunHistoryService.recoderTraceInfo(TaskInfo.FAILURE, info, taskTrace, recoder);
			return;
		}
		System.out.println(dayAtmRunHistoryService.taskTrace==null);

initData方法为dayAtmRunHistoryService父类ATaskService中执行

public boolean initData(IBOTaskRecorder recoder, String[] parms,
			TaskTrace taskTrace) {
		this.recoder = recoder;
		this.taskTrace = taskTrace;
｝

执行后竟然发现 打印为true，而实际上taskTrace 已经赋值过了。经反复测试，发现对dayAtmRunHistoryService去除spring事物管理的时候打印为false.由此判断是spring事物管理的原因造成的。
