Java实现秒杀系统
```java
@Controller
@RequestMapping(seckill)
public class SeckillController {
private final Logger logger = LoggerFactory.getLogger(this.getClass());
@Autowired
private SeckillService seckillService;
@RequestMapping(value=/list,method = RequestMethod.GET)
public String list(Model model){
//获取列表页
List list=seckillService.getSeckillList();
model.addAttribute(list,list);
return list;
}
@RequestMapping(value = /{seckillId}/detail,method = RequestMethod.GET)
public String detail(@PathVariable(seckillId) Long seckillId, Model model){
if (seckillId == null){

}
Seckill seckill = seckillService.getById(seckillId);
if (seckill == null){

}
model.addAttribute(seckill,seckill);
