未将方法织入事务中

spring配置：

<tx:advice id="txAdvice" transaction-manager="txManager">
		<tx:attributes>
			<tx:method name="add*"/>
			<tx:method name="update"/>
			<tx:method name="delete"/>
			<tx:method name="login" read-only="true"/>
			<tx:method name="find*" read-only="true"/>
		</tx:attributes>
</tx:advice>

service层方法：

public void updateStaff(CrmStaff staff){
		CrmStaff findStaff = staffDao.findById(staff.getStaffId());
		if (!findStaff.getLoginPwd().equals(staff.getLoginPwd())) {
			findStaff.setLoginPwd(staff.getLoginPwd());
		}
		findStaff.setLoginName(staff.getLoginName());
		findStaff.setStaffName(staff.getStaffName());
		findStaff.setGender(staff.getGender());
		findStaff.setOnDutyDate(staff.getOnDutyDate());
		findStaff.setPost(staff.getPost());
		System.out.println(findStaff);
	}
