本文介绍了一个关于MyBatis中OGNL语法的错误案例，当字符串'S'作为条件判断时，由于类型识别问题导致了NumberFormatException异常。文章提供了修改前后的XML条件语句对比，并解释了'S'被视为字符而非字符串的原因。

运行环境：mybatis，java，extjs

报错：

org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.exceptions.PersistenceException:
### Error querying database. Cause: java.lang.NumberFormatException: For input string: "S"
