Java - Caused by: org.springframework.data.mapping.PropertyReferenceException: No property
项目中的代码需要增加一个更新时间的SQL，直接使用spring自带的jpa来做吧，balaba写了个update的操作，更新一下操作的时间戳，打包上传服务器，信心满满的./start.sh，打开nohup.out，忽然启动失败，报错了。。。

当然找问题，还是要从最后看起嘛。。。

看了看报的问题，似乎在说我的实体类里面没有这个属性？？？信你个鬼！！！果不其然，使用人家jpa是要遵循人家定的规范的；
| 关键字 | 方法命名 | sql where字句 |
| And | findByNameAndPwd | where name= ? and pwd =? |
| Or | findByNameOrSex | where name= ? or sex=? |
| Is,Equals | findById,findByIdEquals | where id= ? |
| Between | findByIdBetween | where id between ? and ? |
| LessThan | findByIdLessThan | where id < ? |
| LessThanEquals | findByIdLessThanEquals | where id <= ? |
| GreaterThan | findByIdGreaterThan | where id > ? |
| GreaterThanEquals | findByIdGreaterThanEquals | where id > = ? |
| After | findByIdAfter | where id > ? |
| Before | findByIdBefore | where id < ? |
| IsNull | findByNameIsNull | where name is null |
| isNotNull,NotNull | findByNameNotNull | where name is not null |
| Like | findByNameLike | where name like ? |
| NotLike | findByNameNotLike | where name not like ? |
| StartingWith | findByNameStartingWith | where name like '?%' |
| EndingWith | findByNameEndingWith | where name like '%?' |
| Containing | findByNameContaining | where name like '%?%' |
| OrderBy | findByIdOrderByXDesc | where id=? order by x desc |
| Not | findByNameNot | where name <> ? |
| In | findByIdIn(Collection<?> c) | where id in (?) |
| NotIn | findByIdNotIn(Collection<?> c) | where id not in (?) |
| True | findByAaaTue | where aaa = true |
| False | findByAaaFalse | where aaa = false |
| IgnoreCase | findByNameIgnoreCase | where UPPER(name)=UPPER(?) |
把接口里的方法名改为（原updateSendtimeByOpeationId）findSendtimeByOpeationId，就OK了，嘿嘿嘿。。。
