mybatis报 ：Error querying database. Cause: java.lang.NumberFormatException: For input string: “XX”

这是由于mybatis参数格式化异常导致，例如在动态sql拼接中String类型参数和数字比较,这里需要把 ’ 使用&quot进行转义

<when test="paramMap.sort=='c'"> //错误写法
 i.sell_counts desc
</when>
<when test="paramMap.sort==&quot;c&quot;">//正确写法
 i.sell_counts desc
  </when>
