spring boot 注解

@RestController  等同于@Controller + @ResponseBody
@RequestMapping();
例如：

@RestController
@RequestMapping("/test/atest")
public class AtestController {
    @Autowired
    private RedisUtil redisUtil;
    
    @RequestMapping("test1")
    public Object list() {
        Map<String, String> user = new HashMap<>();
        map.put("name","xys");
        map.put("age","18");
            return map;
    }
}
