MyBatis exception: Org.apache.ibatis.binding.BindingException:Parameter ' param ' not found. Available param

Org.apache.ibatis.binding.BindingException:Parameter ' param ' not found. Available parameters is [param1, form]

Cause: There are many reasons to report this error, usually the configuration file is wrong, one solution is to replace the lower version of the jar package, such as mybatis-3.0.5, which can not fundamentally solve the problem. I encountered a map with the parameters used in the mapper, but it was not taken out of the map in the configuration file, but was used directly. For example, the map has the ID, name, and the configuration file directly using #{id} ${name} will be reported as a similar exception, to #{map.id} OK
