map在Sql中的传参 模糊查询limit分页

mapper.xml页面
sql传入map，需要用${},不能用#{}


    <select id="findAllByCountName" parameterType="java.util.Map" resultType="bean.ChuHuoDan" >

  　　　　<!-- SELECT * FROM chuhuodan WHERE siji LIKE  '%张%' ORDER BY createtime DESC limit 0,5; -->

    SELECT * FROM chuhuodan WHERE siji LIKE  ${moHuName} ORDER BY createtime DESC limit ${pageNum},${pageSize}

   </select>

serviceImpl层

  @Override
    public List<ChuHuoDan> findAllByCountName(String moHuName, Integer pageNum, Integer pageSize) {
        moHuName="'%"+moHuName+"%'";
        System.out.println (moHuName);
        map.put ( "moHuName",moHuName );
        map.put ( "pageNum" ,pageNum);
        map.put ( "pageSize",pageSize );
        return chuHuoDanMapper.findAllByCountName(map);
    }

 

 

Controller层

    @RequestMapping("findChuHuoDanByCountName")
    public String findChuHuoDanByCountName(Model model, String moHuName,
