今天写项目，写到多个参数从数据库取数据时，一直报这个错，经过查找资料等，终于成功解决，解决前代码为

DAO层

修改前：

public  List getSC(String couId,String classname);  

mapper.xml

修改前：

 
    select * from sortcourse where couId=#{couId} and classname=#{classname}

因为mapper配置文件中parameterType为String，只能接收一个参数，故将parameterType属性去掉

则修改第一步：将mapper.xml中将parameterType属性去掉

修改后：

 
    select * from sortcourse where couId=#{couId} and classname=#{classname}

修改第二步：将DAO成代码修改为

修改后：

public  List getSC(@Param("couId")String couId,@Param("classname")String classname);

再导入Param包

问题成功解决！！
