org.springframework.dao.InvalidDataAccessApiUsageException: Parameter value [41] did not match expected type [java.lang.Integer (n/a)];

题记：以前记录过一些自己遇到的BUG，这个行为，让我一看报错的提示信息就能定位到问题的所在，后来记得比较多了，好多是重复性的再加上比较忙就没有详细的记录了，今天的工作量比较小，就顺便记录一下，以便以后更快的解决此类问题。

BUG的报错信息如下所示：

org.springframework.dao.InvalidDataAccessApiUsageException: Parameter value [41] did not match expected type [java.lang.Integer (n/a)]; nested exception is java.lang.IllegalArgumentException: Parameter value [41] did not match expected type [java.lang.Integer (n/a)]

分析：

根据以往的经验基本的分析思路如下：

1：先看错误的提示信息，判断是否是自己已经熟悉的问题，如果是快速定位解决一下

2：如果光看错误的提示信息不能准确定位到问题的所在，就找到错误提示信息中自己编写的代码部分看一下能否发现问题的所在，比如，针对此问题，我自己编写的代码如下所示

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：从这些代码中将公共的部分再去掉一次，留下自己单独编写的部分（一般情况下，公共的部分出错的概率比较小，当然也是有可能的需要一步步排查，先从最有可能出问题的地方着手）

4：经过分析没有发现公共的代码和自己编写的代码有什么问题，这其实是证明没有准确的定位到问题的所在

5：采用调试模式跟踪程序的运行看看程序实在什么地方抛的错误，如果是自己编写代码，那么问题应该能定位到了

6：如果是框架本身报错的错误，又需要回头来看一下错误信息了（一般情况下，框架是比较健壮的），比如：此次问题中有这么一句话

Caused by: java.lang.IllegalArgumentException: Parameter value [41] did not match expected type [java.lang.Integer (n/a)]

7：现在基本能判断出，问题是由于数据类型转换导致的，但是程序中没看到那里有数据类型的转换的过程，当情况是这样的时候就只能再次的调试一下程序了，并且再次的检查一下和报错相关的一些代码了，比如：那一段程序报错，和她相关的地方也再次的检查一下，如果这一招还不能够将问题解决掉，只能求助于搜索引擎和其他的同事了

8：当我回头再次检查程序及其关联的一些代码时，我终于发现了问题的所在，如下面的系类图所示：

9：现在又引出一个问题了，究竟该怎么定义这个字段（equCategoryId）的数据类型那，我们来看一下数据库中的定义

以及MySQL中bigint的定义

10：好了，到此，这个问题已经解决了，修改一下试图中定义的数据类型再调试一下，OK
