jquery.edatagrid（可编辑datagrid）的使用

用spring+springmvc+mybatis+mysql实现简单的可编辑单元格，首先是页面效果图：

其中，“编号”列是不可编辑的，“暂缓措施”是可以自由编辑的，主要html组成：

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

 $(function(){
     $("#dg").edatagrid({
        url:‘${pageContext.request.contextPath}/customerReprieve/list.do?lossId=${param.lossId}‘,
        saveUrl:‘${pageContext.request.contextPath}/customerReprieve/save.do?customerLoss.id=${param.lossId}‘,
        updateUrl:‘${pageContext.request.contextPath}/customerReprieve/save.do‘,
        destroyUrl:‘${pageContext.request.contextPath}/customerReprieve/delete.do‘
     });
 });

 function confirmLoss(){
     $.messager.prompt(‘系统提示‘, ‘请输入流失原因：‘, function(r){
            if (r){
                $.post("${pageContext.request.contextPath}/customerLoss/confirmLoss.do",{id:‘${param.lossId}‘,lossReason:r},function(result){
                    if(result.success){
                         $.messager.alert("系统提示","执行成功！");
                    }else{
                        $.messager.alert("系统提示","执行失败！");
                    }
                },"json");
            }
        });
 }

<title>Insert title here</title>

<body style="margin: 15px">

     <a href="javascript:void(0)" class="easyui-linkbutton" iconCls="icon-confirm" plain="true" onclick="javascript:confirmLoss()">确认流失</a>
 </div>
</body>
</html>

edatagrid中定义了四个url属性，代表四种操作的请求路径，分别为url（列表查询url）、saveUrl（更新保存url）、updateUrl（新增保存url）、deleteUrl（删除url）

主要的controller实现：

/**
 * 客户流失暂缓措施Controller层
 * @author Administrator
 *
 */
@Controller
@RequestMapping("/customerReprieve")
public class CustomerReprieveController {

    @Resource
    private CustomerReprieveService customerReprieveService;

    /**
     * 分页条件查询客户流失暂缓措施
     * @param page
     * @param rows
     * @param s_customerReprieve
     * @param response
     * @return
     * @throws Exception
     */
    @RequestMapping("/list")
    public String list(@RequestParam(value="lossId",required=false)String lossId,HttpServletResponse response)throws Exception{
        Map<String,Object> map=new HashMap<String,Object>();
        map.put("lossId", lossId);
        List<CustomerReprieve> customerReprieveList=customerReprieveService.find(map);
        JSONObject result=new JSONObject();
        JsonConfig jsonConfig=new JsonConfig();
        jsonConfig.setExcludes(new String[]{"customerLoss"});
        JSONArray jsonArray=JSONArray.fromObject(customerReprieveList,jsonConfig);
        result.put("rows", jsonArray);
        ResponseUtil.write(response, result);
        return null;
    }

    /**
     * 添加或者修改客户流失暂缓措施
     * @param customerReprieve
     * @param response
     * @return
     * @throws Exception
     */
    @RequestMapping("/save")
    public String save(CustomerReprieve customerReprieve,HttpServletResponse response)throws Exception{
        int resultTotal=0; // 操作的记录条数
        if(customerReprieve.getId()==null){
            resultTotal=customerReprieveService.add(customerReprieve);
        }else{
            resultTotal=customerReprieveService.update(customerReprieve);
        }
        JSONObject result=new JSONObject();
        if(resultTotal>0){
            result.put("success", true);
        }else{
            result.put("success", false);
        }
        ResponseUtil.write(response, result);
        return null;
    }

    /**
     * 删除客户流失暂缓措施
     * @param ids
     * @param response
     * @return
     * @throws Exception
     */
    @RequestMapping("/delete")
    public String delete(@RequestParam(value="id")String id,HttpServletResponse response)throws Exception{
        customerReprieveService.delete(Integer.parseInt(id));
        JSONObject result=new JSONObject();
        result.put("success", true);
        ResponseUtil.write(response, result);
        return null;
    }
}

CustomerReprieveService（接口及实现类）主要实现：

/**
 * 客户流失暂缓措施Service接口
 * @author Administrator
 *
 */
public interface CustomerReprieveService {

    /**
     * 查询客户流失暂缓措施集合
     * @param map
     * @return
     */
    public List<CustomerReprieve> find(Map<String,Object> map);

    /**
     * 获取总记录数
     * @param map
     * @return
     */
    public Long getTotal(Map<String,Object> map);

    /**
     * 修改客户流失暂缓措施
     * @param customerReprieve
     * @return
     */
    public int update(CustomerReprieve customerReprieve);

    /**
     * 添加客户流失暂缓措施
     * @param customerReprieve
     * @return
     */
    public int add(CustomerReprieve customerReprieve);

    /**
     * 删除客户流失暂缓措施
     * @param id
     * @return
     */
    public int delete(Integer id);

}

/**
 * 客户流失暂缓措施Service实现类
 * @author Administrator
 *
 */
@Service("customerReprieveService")
public class CustomerReprieveServiceImpl implements CustomerReprieveService{

    @Resource
    private CustomerReprieveDao CustomerReprieveDao;

    @Override
    public List<CustomerReprieve> find(Map<String, Object> map) {
        return CustomerReprieveDao.find(map);
    }

    @Override
    public Long getTotal(Map<String, Object> map) {
        return CustomerReprieveDao.getTotal(map);
    }

    @Override
    public int update(CustomerReprieve customerReprieve) {
        return CustomerReprieveDao.update(customerReprieve);
    }

    @Override
    public int add(CustomerReprieve customerReprieve) {
        return CustomerReprieveDao.add(customerReprieve);
    }

    @Override
    public int delete(Integer id) {
        return CustomerReprieveDao.delete(id);
    }

}

接下来是dao层实现：

/**
 * 客户流失暂缓措施Dao接口
 * @author Administrator
 *
 */
public interface CustomerReprieveDao {

    /**
     * 查询客户流失暂缓措施集合
     * @param map
     * @return
     */
    public List<CustomerReprieve> find(Map<String,Object> map);

    /**
     * 获取总记录数
     * @param map
     * @return
     */
    public Long getTotal(Map<String,Object> map);

    /**
     * 修改客户流失暂缓措施
     * @param customerReprieve
     * @return
     */
    public int update(CustomerReprieve customerReprieve);

    /**
     * 添加客户流失暂缓措施
     * @param customerReprieve
     * @return
     */
    public int add(CustomerReprieve customerReprieve);

    /**
     * 删除客户流失暂缓措施
     * @param id
     * @return
     */
    public int delete(Integer id);

}

因为采用的是mybatis进行ORM映射，所以不必手动写sql，主要映射文件如下：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.dao.CustomerReprieveDao">

        <result property="id" column="id"/>
        <result property="measure" column="measure"/>
        <association property="customerLoss" column="lossId" select="com.dao.CustomerLossDao.findById"></association>
    </resultMap>

    <select id="find" parameterType="Map" resultMap="CustomerReprieveResult">
        select * from t_customer_reprieve
        <where>
            <if test="lossId!=null and lossId!=‘‘ ">
                and lossId = #{lossId}
            </if>
        </where>
        <if test="start!=null and size!=null">
            limit #{start},#{size}

    </select>

    <select id="getTotal" parameterType="Map" resultType="Long">

                and lossId = #{lossId}
            </if>
        </where>
    </select>

    <insert id="add" parameterType="CustomerReprieve">
        insert into t_customer_reprieve values(null,#{customerLoss.id},#{measure})
    </insert>

    <update id="update" parameterType="CustomerReprieve">
        update t_customer_reprieve
        <set>
            <if test="measure!=null and measure!=‘‘ ">
                measure=#{measure},
            </if>
        </set>
        where id=#{id}
    </update>

    <delete id="delete" parameterType="Integer">
        delete from t_customer_reprieve where id=#{id}
    </delete>

</mapper>
