今天这篇文章是我们这个SSM框架系列的最后一篇，主要是用来实现统计题目答案功能的实现。
一.UI设计及功能实现

功能实现:乍一看，我们就知道这是实现了连表查询，点击统计按钮，我们要查询的是qsn表，qsn_detail表以及psg_qsn_表，分别对应题目表，选项表以及答案表。而我们要提交到后端的，就是查询的对应模板的model_id即可。
二.代码实现
统计按钮:
$('#btn-count').click(function() {
layer.open({
type: 1,
skin: 'layui-layer-rim', //加上边框
area: ['900px', '500px'], //宽高
content: $('#set-count'),
title: "统计数据"
});
});
统计弹出层:
<!--统计弹出层-->
<div id="set-count" style="display:none; width:900px; padding:20px;">
<form class="layui-form">
<div class="layui-form-item">
<label class="layui-form-label"></label>
<div class="layui-input-block">
<label class="layui-form-label">模板信息</label>
<label class="layui-form-label" name="count_model_id"></label>
<label class="layui-form-label" name="count_model_name"></label>
<!-- <input type="hidden" name="model_id" id="model_id"> -->
<hr class="layui-bg-red">
</div>
<div class="layui-input-block">
<label class="layui-form-label">题目信息</label>
</div>
<br />
<div class="layui-input-block">
<label class="layui-form-label-col" name="qsn_count"></label>
</div>
</div>
</form>
<!-- <div class="layui-collapse" name="qsn_count" lay-accordion> </div> -->
</div>
以及统计按钮的ajax刷新：
else if (layEvent == 'count') {
layer.msg("加载中", {
icon: 16,
shade: 0.01,
time: '9999999'
});
$('#set-count label[name="count_model_id"]').text(data.model_id);
$('#set-count label[name="count_model_name"]').css("width", "200px");
$('#set-count label[name="count_model_id"]').css("width", "200px");
$('#set-count label[name="count_model_name"]').text(data.name); //弹出层的初始化
var model_id = data.model_id; //将当前选中行的code给code变量
var url = "survey/count";
var data = {
model_id: model_id
};
$.post(url, data, function(data) {
layer.close(layer.index); //关闭正在加载中弹出层
if (data.code == 1) {
layer.open({
type: 1,
skin: 'layui-layer-rim', //加上边框
area: ['1000px', '600px'], //宽高
content: $('#set-count')
});
$('#set-count label[name="qsn_count"]').html(""); //清空info内容
for (var i = 0; i < data.data.length; i++) {
var all;
var content = " ";
var title = '';
// alert(data.data[i].content);
if (data.data[i].qsn_type == 0 || data.data[i].qsn_type == 1) {
title = '<div class="layui-input-block">第' + (i + 1) + '题: ' + data.data[i].content + '</div>';
var count = data.data[i].option_list.length;
for (var j = 0; j < count; j++) {
content = content + '<div class="layui-input-block">' + letter[data.data[i].option_list[j].order_num - 1] + ':' + data.data[i].option_list[j].option_num + ' <br/> 被' + data.data[i].option_list[j].count + '次点击</div><br/>';
}
all = title + content;
$('#set-count label[name="qsn_count"]').append(all);
$('#set-count label[name="qsn_count"]').append(' <hr class="layui-bg-red">');
// else {
title = null;
content = null;
all = null;
} else if (data.data[i].qsn_type == 2) {
// alert(data.data[i].content);
title = '<div class="layui-input-block">第' + (i + 1) + '题: ' + data.data[i].content + '</div>';
var count = data.data[i].answer.length;
for (var j = 0; j < count; j++) {
content = content + '<div class="layui-input-block">乘客答案:' + data.data[i].answer[j].choose + '</div>';
}
all = title + content;
$('#set-count label[name="qsn_count"]').append(all);
$('#set-count label[name="qsn_count"]').append(' <hr class="layui-bg-red">');
title = null;
content = null;
all = null;
}
// }
};
} else {
layer.msg(data.msg, {
icon: 5
});
}
}, "json");
}
});
这里我们只上传了一个model_id作为连表查询的条件。
然后我们看看Controller层代码:
//统计模板信息survey/count
@RequestMapping(value="Index/survey/count")
@ResponseBody
public Map<String,Object> countModel(HttpServletRequest req) throws IOException{
String model_Id = req.getParameter("modelId");
if (model_Id==null){
return api.returnJson(3,"warning");
}
List<Qsn> chk_qsn=qsnService.findQsnList(model_Id);
if (chk_qsn.isEmpty()){
return api.returnJson(2,"暂无题目");
}
//有题目就查qsn和qsn_detail
List<Map> returnlist=new ArrayList();
List<Qsn> qsnList=qsnService.findQsnList(model_Id);
for (int i = 0; i <qsnList.size() ; i++) {
Map map=new HashMap();
if ("2".equals(qsnList.get(i).getQsnType())){
// return api.returnJson(1,"此路不通");
Detail ask_detail=detailService.findAskAnswer(qsnList.get(i).getQsnId());
List<Choose> countlist=chooseService.countDataBy2Id(qsnList.get(i).getQsnId(),ask_detail.getDetailId());
List<Map> answer=new ArrayList<>();
for (int j = 0; j <countlist.size() ; j++) {
Map map1=new HashMap();
map1.put("choose",countlist.get(j).getChoose());
answer.add(map1);
}
map.put("content",qsnList.get(i).getContent());
map.put("qsn_type",qsnList.get(i).getQsnType());
map.put("answer",answer);
returnlist.add(map);
continue;
}
List<Detail> optionList=detailService.findOptionList(qsnList.get(i).getQsnId());//qsnId
List<Map> list=new ArrayList<>();
for (int j = 0; j <optionList.size() ; j++) {//detailId,option_num,order_num
Map map1=new HashMap();
List<Choose> countlist=chooseService.countDataBy2Id(qsnList.get(i).getQsnId(),optionList.get(j).getDetailId());
int count=countlist.size();
map1.put("count",count);
map1.put("detailId",optionList.get(j).getDetailId());
map1.put("optionNum",optionList.get(j).getOptionNum());
map1.put("orderNum",optionList.get(j).getOrderNum());
list.add(map1);
}
map.put("content",qsnList.get(i).getContent());
map.put("qsn_type",qsnList.get(i).getQsnType());
map.put("option_list",list);
returnlist.add(map);
}
return api.returnJson(1,"success",returnlist);
}
用到的chooseService等service层代码可以翻看我前一篇文章。
返回的json数据:
