注意java的对象引用

浏览数：19 / 时间：2015年06月08日

要注意，当前拿到的“对象引用”，是不是指向最新的实例，没有的话，要重新生成实例去指向。

代码例子：

AnsweringRuleInfo bhRule = accountGenerator.getAnswerRule(mailboxId, false, AnsweringRuleType.BusinessHours);
            for(int j=0; j<bhRule.getPhones().size();j++){
                bhRule.getPhones().get(j).setEnabled(false);
                bhRule.setPhones(Arrays.asList(bhRule.getPhones().get(j)));
            }
            accountGenerator.setAnswerRule(mailboxId, bhRule);

解析：

bhRule.getPhones().get(j).setEnabled(false); 操作后，若不对bRule重新设置：bhRule.setPhones(Arrays.asList(bhRule.getPhones().get(j))); （bhRule.getPhones(). 返回List<ForwardPhoneInfo>）

accountGenerator.setAnswerRule(mailboxId, bhRule) 后，该account 下ForwardPhoneInfos 各个ForwardPhoneInfo 保持原来的status，映射不到。

        RingGroup ringGroup4;
        ss.getUserCallHandlingComponent().save();
        openCallForwarding(hours);
        ringGroup4 = ss.getUserCallHandlingComponent().getRingGroupByLabel(hours, firstDeskPhoneLabel);
        ArrayList<String> phoneLabels = ringGroup4.getPhoneLabelsInGroup();
        assertEquals(phoneLabels.get(0), firstDeskPhoneLabel, "The ring group include " + firstDeskPhoneLabel);
        assertEquals(phoneLabels.get(1), forwardPhoneNames[1], "The ring group include " + forwardPhoneNames[1]);
        assertEquals(phoneLabels.size(), 2, "The ring group size is 2");
        assertFalse(ringGroup4.isMoveUpButtonEnabled(), "The ringGroup move up button is disable.");
        assertTrue(ringGroup4.isMoveDownButtonEnabled(), "The ringGroup move down button is enable.");
        logBusiness("1.2 Move the group at the middle of list using ‘\\/‘ arrow > Save > Check arrows for this group at the \"Call Handling & Forwarding\"");
        ringGroup4.moveGroupDown();
        ringGroup4 = ss.getUserCallHandlingComponent().getRingGroupByLabel(hours, firstDeskPhoneLabel);
        ss.getUserCallHandlingComponent().save();
        openCallForwarding(hours);
        assertTrue(ringGroup4.isMoveUpButtonEnabled(),"The ringGroup move up button is enable.");
        assertTrue(ringGroup4.isMoveDownButtonEnabled(), "The ringGroup move down button is enable.");
