jquery.edatagrid（可编辑datagrid）的使用

2015-11-11 21:44 776 查看
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">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<script type="text/javascript">

$(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");
}
});
}

</script>

<body style="margin: 15px">

</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}
</if>
</select>

<select id="getTotal" parameterType="Map" resultType="Long">
select count(*) from t_customer_reprieve
<where>
<if test="lossId!=null and lossId!='' ">
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>
