jeefast和Mybatis实现三级联动的示例代码

<!--			学校-->
			<div class="form-group">
				<div class="col-sm-2 control-label">学校</div>
				<select v-model="student.id" class="col-sm-2" @change="getDayGrade()" id="selectid" >
					<option value="0">--请选择学校--</option>
					<option v-for="(v,index) in school" :value="v.id" >{{v.name}}</option>
				</select>
			</div>

getDaySchool:function () {
			$.ajax({
				type: "POST",
				url: baseURL + "platform/notice1/All123",
				contentType: "application/json",
				success: function (r) {
					if (r.code === 0) {
						vm.school = r.school;
						vm.student.gid=0;
						vm.student.cid=0;
					}else {
					}
				}
			});
		}

@RequestMapping("/All123")
	public R list(){
		Map<String,Object> map = new HashMap<>();
		List<School> list = schoolService.selectByMap(map);
		return R.ok().put("school", list);
	}
