报错位置代码:Long selelct=(Long) selectRepeatNum.get("dictionaryVaule");//字典表中的唯一序列号 //???如果字典中没有dictonaryValue,会报空指针异常
解决方法:暂时为数据库s_dictonary中加入数据acctOnlyFlag,202001131510890

解决方法:
String customizeTimeFormat=sdf2.parse(transTime).toString();(这一步实际是先解析成日期,再转换成字符串)

错误原因:截取空串造成的
if(cardNumber!=null) {
//如果卡号不为空
cardOrAccount=cardNumber;
System.out.println("cardOrAccount卡号:"+cardOrAccount);
String cutAccount=cardOrAccount.substring(cardOrAccount.length()- 4);//截取账号或卡号后四位
allParas.put("cutAccount",cutAccount);//账号或卡号后四位
allParas.put("cardOrAccount", cardOrAccount);
解决方案:增加判断条件
if(cardNumber!=null&&cardNumber.length()!=0)
原理解释:
判断一个字符串是否为空,首先就要确保他不是null,然后再判断他的长度。
String str = xxx;
if(str != null && str.length() != 0) { }

错误原因:
Map selectSignMsg(@Param("cardNum")String cardOrAccount);
原理解释:
采用#{}的方式把@Param注解括号内的参数进行引用(括号内参数对应的是形参)
解决方案:
Map selectSignMsg(@Param("cardOrAccount")String cardOrAccount);
注意:dao层用map类型接收,需要在mapper.xml文件中声明resultType="map"
例如:
/**
* 查询字典表中dictionaryVaule值
*/
Map selectDictionaryVaule();
<!-- 查询字典表中dictionaryVaule值 -->
<select id="selectDictionaryVaule" resultType="map" >
select dictionaryVaule from s_dictionary where dictionaryKey="acctOnlyFlag"
</select>

原因分析:
Map signMsgInsertSendMsgB(Map signMsgSaveSendMsgB);
数据封装在了map中,mapper,xml文件中没有遍历取出手机号,导致报手机号不能为空的错误
