測試用的Controller

import com.example.service.RedisService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.RestController;@RestControllerpublic class DemoController {    @Autowired    private RedisService redisService ;    @RequestMapping(value = "/test",method = RequestMethod.POST)    public void demoTest(){        redisService.set("1","value22222");    }}
