我试过加@ResponseBody注解转换json数据,但是前台layui数据显示 “请求异常,错误提示:error” ,如果不转json数据的话layui是不是就接收不到list循环出来的数据了?
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;
import susu.entity.Commodities;
import susu.service.CommoditisService;
import java.util.List;
@Controller
public class CommoditisController {
@Autowired
private CommoditisService service;
@ResponseBody
@RequestMapping(value = "/stock_supplier.do", method = RequestMethod.POST)
public ModelAndView select_commoditis(){
ModelAndView mv = new ModelAndView();
List<Commodities> list = service.select_commodities(1);
for (Commodities c : list) {
System.out.println(c.getCdsid()+"\t"+c.getCdsname()+"\t"+c.getCdsnum());
mv.addObject("cdsid",c.getCdsid());
mv.addObject("cdsname",c.getCdsname());
mv.addObject("cdsurl",c.getCdsurl());
mv.addObject("cdsnum",c.getCdsnum());
mv.addObject("catid",c.getCatid());
mv.addObject("catname",c.getCategories().getCatname());
System.out.println(mv);
mv.setViewName("stock_supplier");
}
System.out.println("数据查询成功");
return mv;
}
}
此时控制台打印的数据是这样的:
1 风扇 风不大
ModelAndView: materialized View is [null]; model is {cdsid=1, cdsname=风扇, cdsurl=z1.png, cdsnum=风不大, catid=1, catname=植物}
2 风扇plus 风很凉快
ModelAndView: reference to view with name 'stock_supplier'; model is {cdsid=2, cdsname=风扇plus, cdsurl=z2.png, cdsnum=风很凉快, catid=1, catname=植物}
前台的layui:
layui的部分代码:
<script>
//加载模块
layui.use(['layer','laypage','table','form','util'], function() {
var cxt = '${pageContext.request.contextPath}';
//得到各种内置组件
var layer = layui.layer //弹层
, laypage = layui.laypage //分页
, table = layui.table //表格
, form = layui.form
, util = layui.util
//执行一个 table 实例
table.render({
elem: '#demo'
,id: 'tableId'
,height: 420
,method: 'post'
// ,toolbar: '#toolbarDemo'
// ,dataType: "json"
// ,contentType: "application/json"
,url: 'stock_supplier.do' //数据接口
,parseData: function(res){ //res 即为原始返回的数据
return {
"code": res.status, //解析接口状态
"msg": res.message, //解析提示文本
"count": res.total, //解析数据长度
"data": res.data.item //解析数据列表
};
}
,title: '供应商'
,response: {
statusName: 'code' //规定数据状态的字段名称,默认:code
,statusCode: 200 //规定成功的状态码,默认:0
,msgName: 'msg' //规定状态信息的字段名称,默认:msg
,countName: 'count' //规定数据总数的字段名称,默认:count
,dataName: 'data' //规定数据列表的字段名称,默认:data
}
// ,page: true //开启分页
// ,toolbar: 'default' //开启工具栏,此处显示默认图标,可以自定义模板,详见文档
,cols: [[ //表头
{type: 'checkbox', fixed: 'left'}
,{field: 'cdsid', title: 'ID', width:100, sort: true}
,{field: 'cdsname', title: '名称', width:100}
,{field: 'catname', title: '种类', width: 100}
,{field: 'cdsurl', title: '展示', width: 300}
,{field: 'cdsnum', title: '描述'}
,{field: 'right', toolbar: '#btn_bar', title: '操作', width: 100}
]]
});
});
</script>
