管理端Controller类

java">package com.sky.controller.admin;import com.sky.result.Result;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.web.bind.annotation.*;/*** 店铺相关接口*/
@RestController("adminShopController")//防止Controller类重名
@RequestMapping("/admin/shop")
@Slf4j
@Api(tags = "店铺相关接口")
public class ShopController {public static final String KEY = "SHOP_STATUS";//使用常量更好@Autowiredprivate RedisTemplate redisTemplate;/*** 设置店铺的营业状态* @param status* @return*/@PutMapping("/{status}")@ApiOperation("设置店铺的营业状态")public Result setStatus(@PathVariable Integer status){log.info("设置店铺的营业状态为: {}",status == 1 ? "营业中":"打烊中");//在Redis创建营业状态字段,并设值redisTemplate.opsForValue().set(KEY,status);return Result.success();}/*** 获取用户的营业状态* @return*/@GetMapping("/status")@ApiOperation("获取用户的营业状态")public Result<Integer> getStatus(){Integer status = (Integer) redisTemplate.opsForValue().get(KEY);log.info("获取用户的营业状态：{}",status == 1 ? "营业中":"打烊中");return Result.success(status);}
}

用户端Controller类

java">package com.sky.controller.user;import com.sky.result.Result;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.web.bind.annotation.*;/*** 用户相关接口*/
@RestController("userShopController")//防止Controller类重名
@RequestMapping("/user/shop")
@Slf4j
@Api(tags = "用户相关接口")
public class ShopController {public static final String KEY = "SHOP_STATUS";//使用常量更好@Autowiredprivate RedisTemplate redisTemplate;/*** 获取用户的营业状态* @return*/@GetMapping("/status")@ApiOperation("获取用户的营业状态")public Result<Integer> getStatus(){Integer status = (Integer) redisTemplate.opsForValue().get(KEY);log.info("获取用户的营业状态：{}",status == 1 ? "营业中":"打烊中");return Result.success(status);}
}
