今天寫項目,寫到多個參數從數據庫取數據時,一直報這個錯,經過查找資料等,終於成功解決,解決前代碼為

DAO層

修改前:

public  List<SortCourse> getSC(String couId,String classname);  

mapper.xml

修改前:

 <select id="getSC" parameterType="String" resultType="SortCourse">
    select * from sortcourse where couId=#{couId} and classname=#{classname}
</select>

因為mapper配置文件中parameterType為String,只能接收一個參數,故將parameterType屬性去掉

則修改第一步:將mapper.xml中將parameterType屬性去掉

修改后:

 <select id="getSC"  resultType="SortCourse">
    select * from sortcourse where couId=#{couId} and classname=#{classname}
</select>

修改第二步:將DAO成代碼修改為

修改后:

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

再導入Param包

問題成功解決!!
