jeefast实现一对多

1.效果图：

2.postman查询出来的数据

3.mapper

		
		
		
			
			
		
	
	
		select * from pf_class pc left join pf_student ps on pc.`cid`=ps.`sclass`
	

js端需要循环读取

{ label: '班级编号', name: 'cid', index: "cid", width: 15, key: true },
            { label: '班级名称', name: 'cname', width: 75 },
            { label: '包含人员', name: 'pfStudents', width: 53 ,formatter:function (value,options,row) {
                    var len = value.length;
                    var list = "";
                    for(var i = 0;i<len;i++){
                        list +=value[i].sname;
                        list +=",";
                    }
                    return list;
                }},
        ],

5.其余的和之前一样，controller的都一样
