一次org.springframework.jdbc.BadSqlGrammarException ### Error querying database Cause: ...

先说结论：

因为在表设计中有一个商品描述字段被设置为desc，但desc是mysql中的关键字，如select id,name,desc,price from product;这条sql语句在查询时的sql语句解析会和期望的不一样，导致出现问题。因为平时在写java代码的时候很自然的会将描述变量设置为desc，在设计表字段时也没有多想，忘记和忽略了desc为mysql中的关键字，酿成此问题。

排查思路：

一开始怀疑是因为sql过长，删了一部分，成功了，加上又失败了，而且一直提示在price那里只打印了一半pric所以怀疑是不是price那里有问题。去掉price还是报错，最后一个字段一个字段的删减，最后发现是因为使用了sql关键字，desc,作为表字段造成的。

解决方式：

将商品描述列字段名称由desc修改为description。

总结问题：

在设计表字段时千万不可以使用Mysql中已定义的关键字。
