解決方法：傳入的鍵值對，要對應數據庫的字段類型。
比如oracle的varchar，varchar2要對應 java 的string ，
number要對應java的long。
今天在上班啓動系統的時候，一直提示“SQL state [null]; error code [17004]; 無效的列類型; nested exception is java.sql.SQLException: 無效的列類型”，我就奇怪了，爲啥無端端會提示這個呢，下面貼上堆棧信息：
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.jdbc.UncategorizedSQLException: PreparedStatementCallback; uncategorized SQLException for SQL [select count(*) from ( select * from tb_product ) ap join tb_domain d on ap.domain_id=d.domain_id where d.product_line=? and d.agent_id=?]; SQL state [null]; error code [17004]; 無效的列類型; nested exception is java.sql.SQLException: 無效的列類型

1.我就奇怪了，爲啥會出現這個呢，我仔細查了創建sql的代碼，是用NamedParameterJdbcTemplate的方式查詢數據庫的，參數化鍵值對的方式。
之前也有遇到過類似的問題，之前是因爲放進去的鍵值對，有null的情況，所以提示這個。然後我就debug了很多次，確認鍵值對都是有值的，並沒有null的情況。
2.沒辦法啦，只能百度一下，上面都是說數據庫中時間的參數有null的情況，所以如果date類型的數據有null的時候，在轉換的時候會有問題。
參考博客：
https://blog.csdn.net/weixin_39214481/article/details/80360698
3. 但是我仔細檢查了一下，確實沒有數據爲空的情況啊。
於是我就繼續debug，通過剪枝的方式把sql縮短排查，感謝上帝，千辛萬苦排查後，終於發現，代碼出現的問題是在這裏。
對，就是這個罪灰禍首，浪費我一天的時間。（ProductLine 是一個枚舉類型）
我看了很久，也沒毛病啊，幹啥不行呢？
最後查看了官網相關的資料介紹，才知道sql 的鍵值對，只能存放那8種基本類型進去，對，也就是int ，long, String ,boolean 等，而枚舉類型是不支持的，必須要轉化成對應數據庫的字段類型才能查詢的，啊啊啊啊啊啊，我的天啊，這麼坑人啊。
於是，我看了下源碼，雖然源碼的query（）方法，是可以放一個任意類型進去的。但是查詢的參數類型，要跟數據庫中字段的類型對應，比如oracle的varchar2，varchar 要對應java.util.String；number 要對應java的long纔可以哦。
最後，用這種解決方式，轉成string 之後才放進去啦，最後，成功啦！！！！
