一、登录方式调整
第1步：从zmall-common的pom.xml中移除spring-session-data-redis依赖
注意：
1）本项目中不采用spring-session方式，改用redis直接存储用户登录信息，主要是为了方便之后的jmeter压测；
2）这里只注释调用spring-session的依赖，保留redis的依赖；
第2步：在zmall-common公共模块中定义RedisConfig配置类
@Configuration
public class RedisConfig {
@Bean
public RedisTemplate<String,Object> restTemplate(RedisConnectionFactory redisConnectionFactory){
RedisTemplate<String,Object> redisTemplate=new RedisTemplate<>();
//String类型Key序列化
redisTemplate.setKeySerializer(new StringRedisSerializer());
//String类型Value序列化
redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());
//Hash类型Key序列化
redisTemplate.setHashKeySerializer(new StringRedisSerializer());
//Hash类型Value序列化
redisTemplate.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());
redisTemplate.setConnectionFactory(redisConnectionFactory);
return redisTemplate;
}
}
这里一定要注意，最后在将RedisConnectionFactory设置到RedisTemplate中，不要在最前做该步操作，不然会导致String和Hash类型的序列化无效，将采用默认的JdkSerializationRedisSerializer进行序列化，从而导致保存的key前缀出现乱码问题。细心！！！细心！！！细心！！！o(╥﹏╥)o

第3步：在zmall-common公共模块中配置redis相关服务
IRedisServcie
public interface IRedisService {
/**
* 将登陆用户对象保存到Redis中，并以token来命名
* @param token
* @param user
*/
void setUserToRedis(String token, User user);
/**
* 根据token令牌从Redis中获取User对象
* @param token
* @return
*/
User getUserByToken(String token);
}
RedisServcieImple
@Service
public class RedisServiceImpl implements IRedisService {
@Autowired
private RedisTemplate<String,Object> redisTemplate;
@Override
public void setUserToRedis(String token, User user) {
String key="user:"+token;
redisTemplate.boundValueOps(key).set(user,7200,TimeUnit.SECONDS);
}
@Override
public User getUserByToken(String token) {
return (User) redisTemplate.opsForValue().get("user:"+token);
}
}
用户登录成功后，将用户对象保存到Redis中，并设置超时时间7200秒。
第4步：在zmall-common公共模块中配置，配置自定义参数解析UserArgumentResolver、WebConfig
/**
* 自定义用户参数类
*/
@Component
public class UserArgumentResolver implements HandlerMethodArgumentResolver {
@Autowired
private IRedisService redisService;
/**
* 只有supportsParameter方法执行返回true，才能执行下面的resolveArgument方法
* @param methodParameter
* @return
*/
@Override
public boolean supportsParameter(MethodParameter methodParameter) {
Class<?> type = methodParameter.getParameterType();
return type== User.class;
}
@Override
public Object resolveArgument(MethodParameter methodParameter,
ModelAndViewContainer modelAndViewContainer,
NativeWebRequest nativeWebRequest,
WebDataBinderFactory webDataBinderFactory) throws Exception {
HttpServletRequest req= (HttpServletRequest) nativeWebRequest.getNativeRequest();
//从cookie获取token令牌
String token = CookieUtils.getCookieValue(req, "token");
//判断cookie中的token令牌是否为空
if(StringUtils.isEmpty(token))
throw new BusinessException(JsonResponseStatus.TOKEN_ERROR);
//根据token令牌获取redis中存储的user对象，方便jmeter测试
User user = redisService.getUserByToken(token);
if(null==user)
throw new BusinessException(JsonResponseStatus.TOKEN_ERROR);
return user;
}
}
WebConfig
@Component
public class WebConfig implements WebMvcConfigurer {
@Autowired
private UserArgumentResolver userArgumentResolver;
@Override
public void addArgumentResolvers(List<HandlerMethodArgumentResolver> resolvers) {
resolvers.add(userArgumentResolver);
}
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
//添加静态资源访问映射
//registry.addResourceHandler("/static/**")
// .addResourceLocations("classpath:/static/");
}
}
第5步：用户登录业务调整，将spring-session方式更改为redis方式存储登录用户信息。
//5.通过UUID生成token令牌并保存到cookie中
String token= UUID.randomUUID().toString().replace("-","");
//将随机生成的Token令牌保存到Cookie中，并设置1800秒超时时间
CookieUtils.setCookie(req,resp,"token",token,7200);
//6.将token令牌与spring session进行绑定并存入redis中
//HttpSession session = req.getSession();
//session.setAttribute(token,us);
//将token令牌与user绑定后存储到redis中，方便jmeter测试
redisService.setUserToRedis(token,us);
这里采用Redis方式直接存储登录用户信息，只为后续使用Jmeter压测时提供便利。正常运行使用项目还是可以使用spring-session方式。
第6步：修改商品服务zmall-product模块中的index方法，将之前从HttpSession中获取登录用户信息改换成User对象参数方式
@RequestMapping("/index.html")
public String index(Model model, User user){
System.out.println(user);
}
在调用index方法之前，先由自定义的参数解析器进行参数解析并返回解析结果User，所以在这里可直接在方法参数中获取的User对象。
第7步：重启zmall-user和zmall-product模块，完成用户登录后，直接在浏览器地址栏输入：http://zmall.com/product-serv/index.html，查看zmall-product模块中的控制台是否已经获取到登录用户对象信息。

2.2 查看秒杀商品
点击限时秒杀中的秒杀商品，根据秒杀商品ID查询秒杀商品详情信息并跳转到sellDetail.html页面展示秒杀商品信息。
@RequestMapping("/sellDetail.html")
public String sellDetail(@RequestParam Integer pid, Model model){
//根据商品ID查询秒杀商品信息
Map<String, Object> prod = productService.queryKillProdById(pid);
model.addAttribute("prod",prod);
return "sellDetails";
}
2.3 订单秒杀
2.3.1 移除seata相关（方便测压）
第1步：先注释掉zmall-order和zmall-product模块中的seata依赖
第2步：分别删掉zmall-order和zmall-product模块中resources目录下的bootstrap.xml和register.conf文件
seata分布式事务，进行jmeter压测秒杀订单接口效率太低（1000个并发请求，吞吐量为4.5/s）o(╥﹏╥)o
2.3.2 生成秒杀订单
将SnowFlake雪花ID生成工具类导入到zmall-common模块中utils，然后再生成秒杀订单时使用雪花ID来充当秒杀订单编号；在zmall-order模块中完成秒杀订单生成工作。
IOrderService
public interface IOrderService extends IService<Order> {
Order createOrder(Integer pid,Integer num);
/**
* 生成秒杀订单
* @param user 登陆用户对象
* @param pid 秒杀商品ID
* @param price 秒杀商品价格
* @return
*/
JsonResponseBody<?> createKillOrder(User user, Integer pid, Float price);
}
OrderServiceImpl
@Autowired
private KillServiceImpl killService;
@Autowired
private OrderDetailServiceImpl orderDetailService;
@Transactional
@Override
public JsonResponseBody<?> createKillOrder(User user, Integer pid, Float price) {
//1.根据秒杀商品编号获取秒杀商品库存是否为空
Kill kill = killService.getOne(new QueryWrapper<Kill>().eq("item_id",pid));
if(kill.getTotal()<1)
throw new BusinessException(JsonResponseStatus.STOCK_EMPTY);
//2.秒杀商品库存减一
killService.update(new UpdateWrapper<Kill>()
.eq("item_id",pid)
.setSql("total=total-1"));
//3.生成秒杀订单及订单项
SnowFlake snowFlake=new SnowFlake(2,3);
Long orderId=snowFlake.nextId();
int orderIdInt = new Long(orderId).intValue();
//创建订单
Order order=new Order();
order.setUserId(user.getId());
order.setLoginName(user.getLoginName());
order.setCost(price);
order.setSerialNumber(orderIdInt+"");
this.save(order);
//创建订单项
OrderDetail orderDetail=new OrderDetail();
orderDetail.setOrderId(orderIdInt);
orderDetail.setProductId(pid);
orderDetail.setQuantity(1);
orderDetail.setCost(price);
orderDetailService.save(orderDetail);
return new JsonResponseBody();
}
OrderController
@RequestMapping("/createKillOrder/{pid}/{price}")
@ResponseBody
public JsonResponseBody<?> createKillOrder(User user,
@PathVariable("pid") Integer pid,
@PathVariable("price") Float price){
return orderService.createKillOrder(user,pid,price);
}
2.3.3 前端页面秒杀测试
在sellDetail.html页面中添加订单秒杀JS方法。
<script>
$(function(){
$('.ch_a').click(function(){
let pid=$(this).attr('pid');
console.log(pid);
$.post('http://zmall.com/order-serv/createKillOrder',{
pid:pid},function(rs){
console.log(rs);
if(rs.code===200)
alert('秒杀成功');
else
alert(rs.msg);
},'json');
});
});
</script>
这里虽然已经能正常展示秒杀效果，但是还是存在很多问题，比如：重复抢购问题等等问题。
注意
$.post('http://user.zmall.com/userLogin',{
loginName:loginName,
password:password
},function(rs){
console.log(rs);
if(rs.code===200){
location.href='http://product.zmall.com/index.html';
}else{
alert(rs.msg);
}
},'json');
post方式不能跨二级域名发送请求，location.href可以跨二级域名发送请求；
$(function(){
$('.ch_a').click(function(){
let pid=$(this).attr("pid");
let price=$(this).attr("price");
console.log("pid=%s,price=%s",pid,price);
$.post('http://zmall.com/order-serv/createKillOrder/'+pid+'/'+price,{
},function(rs){
console.log(rs);
if(rs.code===200)
alert('秒杀成功');
else
alert(rs.msg);
},'json');
});
});
$.post(‘http://zmall.com/order-serv/createKillOrder/’+pid+‘/’+price,{},function(rs){});能够正常访问；
$.post(‘http://order.zmall.com/createKillOrder/’+pid+‘/’+price,{},function(rs){});则会出现跨域问题；
