題記：以前記錄過一些自己遇到的BUG，這個行為，讓我一看報錯的提示信息就能定位到問題的所在，后來記得比較多了，好多是重復性的再加上比較忙就沒有詳細的記錄了，今天的工作量比較小，就順便記錄一下，以便以后更快的解決此類問題。
BUG的報錯信息如下所示：

分析：
根據以往的經驗基本的分析思路如下：
1：先看錯誤的提示信息，判斷是否是自己已經熟悉的問題，如果是快速定位解決一下
2：如果光看錯誤的提示信息不能准確定位到問題的所在，就找到錯誤提示信息中自己編寫的代碼部分看一下能否發現問題的所在，比如，針對此問題，我自己編寫的代碼如下所示
at com.hjd.dao.base.IBaseDaoImpl.findAllByConditions(IBaseDaoImpl.java:61)
at main.startup.CrossFilter.doFilter(CrossFilter.java:39)
at com.hjd.base.BaseAction.queryList(BaseAction.java:63)
at com.hjd.action.BusEquipmentAction.queryEquAll(BusEquipmentAction.java:1845)
at com.hjd.service.CommonSvc.findAllByConditions(CommonSvc.java:108)
3：從這些代碼中將公共的部分再去掉一次，留下自己單獨編寫的部分（一般情況下，公共的部分出錯的概率比較小，當然也是有可能的需要一步步排查，先從最有可能出問題的地方着手）
4：經過分析沒有發現公共的代碼和自己編寫的代碼有什么問題，這其實是證明沒有准確的定位到問題的所在
5：采用調試模式跟蹤程序的運行看看程序實在什么地方拋的錯誤，如果是自己編寫代碼，那么問題應該能定位到了
6：如果是框架本身報錯的錯誤，又需要回頭來看一下錯誤信息了（一般情況下，框架是比較健壯的），比如：此次問題中有這么一句話
Caused by: java.lang.IllegalArgumentException: Parameter value [41] did not match expected type [java.lang.Integer (n/a)]
7：現在基本能判斷出，問題是由於數據類型轉換導致的，但是程序中沒看到那里有數據類型的轉換的過程，當情況是這樣的時候就只能再次的調試一下程序了，並且再次的檢查一下和報錯相關的一些代碼了，比如：那一段程序報錯，和她相關的地方也再次的檢查一下，如果這一招還不能夠將問題解決掉，只能求助於搜索引擎和其他的同事了
8：當我回頭再次檢查程序及其關聯的一些代碼時，我終於發現了問題的所在，如下面的系類圖所示：
9：現在又引出一個問題了，究竟該怎么定義這個字段（equCategoryId）的數據類型那，我們來看一下數據庫中的定義
以及MySQL中bigint的定義
10：好了，到此，這個問題已經解決了，修改一下試圖中定義的數據類型再調試一下，OK
