校园商铺-2项目设计和框架搭建-10验证controller

1.新建package：com.csj2018.o2o.web.superadmin

2.建立AreaController.java

package com.csj2018.o2o.web.superadmin;

import java.util.ArrayList;

import java.util.HashMap;

import java.util.List;

import java.util.Map;

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 com.csj2018.o2o.entity.Area;

import com.csj2018.o2o.service.AreaService;

@Controller

@RequestMapping("/superadmin") //我们想调用Controller下面的方法必须在/superadmin这个路径下去调用

public class AreaController {

	@Autowired

	private AreaService areaService;

	@RequestMapping(value="/listarea", method=RequestMethod.GET)//加一个路由指定方法名和请求类型。约定：凡是前端访问的方法都是小写，便于URL编写

	@ResponseBody //指定返回值将modelMap对象自动转换成json对象返回给前端

	private Map<String, Object> listArea(){

		Map<String, Object> modelMap = new HashMap<String, Object>();

		List<Area> list = new ArrayList<Area>();

		try {

			list = areaService.getAreaList();

			modelMap.put("rows", list);

			modelMap.put("total",list.size());

		}catch(Exception e) {

			e.printStackTrace();

			modelMap.put("success",false);

			modelMap.put("errMsg",e.toString());

		}

		return modelMap;

	}

}
