萌新已被报错代码弄蒙，多次尝试无法修正。。求大神。。。

感觉大神百忙之中能有兴趣替我解答问题。。。现在报错无法解决
第一次参与和同学做项目，没经验很不熟练，自己百度+研究一上午也没有解决。。。


一个录入分数的页面。SSM的框架
controller的代码

package com.sjzc.match.mark.controller;

import java.util.ArrayList;

import java.util.List;

import com.sjzc.match.common.model.Score;

import com.sjzc.match.mark.service.MarkService;

@Controller

@RequestMapping("/mark/*")

public class MarkController {	

      @Autowired

	private MarkService markService;	

     /**

      * 	成绩

      * @param score 成绩

      * @param response 

      * @param request

      * @throws Exception

      */

		public void dosome(MarkList markList,HttpServletRequest request) {

			List<Score> sl=new ArrayList<Score>();

			sl.add(markList.getScore1());

                        //其实是Score1到Score12

                        //......

			sl.add(markList.getScore12());					

			}	               

	@RequestMapping("markSave.action")

	public String saveScore(

			Score score,

			HttpServletResponse response,HttpServletRequest request, List<Score> sl)throws Exception{

		Score newScore = markService.addOrUpdateScore(score,sl);

		request.setAttribute("score", newScore);

		return "second/03grxx/04cjxx_show";	

	}

}

marklist的代码

package com.sjzc.match.mark.controller;



import com.sjzc.match.common.model.Score;



public class MarkList {



private Score score1;

//......

private Score score12;



public Score getScore1() {

return score1;

}

public void setScore1(Score score1) {

this.score1 = score1;

}

//.......

public Score getScore12() {

return score12;

}

public void setScore12(Score score12) {

this.score12 = score12;

}



public MarkList(Score score1.......Score score12) {

super();

this.score1 = score1;

//.......

this.score12 = score12;

}

}

这是mapper.java

package com.sjzc.match.mark.mapper;

import java.util.List;

import org.springframework.stereotype.Repository;

import com.sjzc.match.common.model.Score;

@Repository

public interface MarkMapper {

 	    void addMark(Score score, List<Score> sl);		

	    Score selectByPrimaryKey(Integer id);

	    int updateByPrimaryKeySelective(Score score, List<Score> sl);						

	}

mapper.xml的代码


后面还有一点update的剩余部分，其他没了。不影响就不贴出来占地方了
这是service的代码

package com.sjzc.match.mark.service;

import java.util.List;

import javax.servlet.http.HttpServletRequest;

import com.sjzc.match.common.model.Score;



/**

 * 

 * 用户需求用到接口

 *

 */

public interface MarkService {

	public Score addMark(Score score, List<Score> sl);	

	Score updateScore(Score score, List<Score> sl);

	Score addOrUpdateScore(Score score, List<Score> sl)；

}

之后的serviceimpl就是一个判断score是否存在而选择insert还是update的。应该不是出错的原因就不贴了。。。
