Mybatis，String类型条件的字符串需要带单引号

cityName是String类型

List cityNameList = areaService.queryByTableType(new AreaQO("忻州"));

  
        select
        city_name
        from


        
            area_table
        
        
            weather_table
        
        
        where 1=1
        
         
            and city_name=#{cityName}
