springmvc在使用@ModelAttribute注解获取Request和Response会产生线程并发不安全问题(续)

通过前面的文章:https://blog.csdn.net/hanjun0612/article/details/103421903
我们知道 由于@ModelAttribute 导致的线程不安全问题,
引起了 session 混乱。
我这里有个实际情况,原先(错误例子)的代码如下:
我在基类中,获取了全局变量的 SysUser curUser;
public class SuperBaseController { protected HttpServletRequest request; protected HttpServletResponse response; private SysUser curUser; @Value("${isDebug}") protected Boolean isDebug; @ModelAttribute public void setLang(HttpServletRequest request, HttpServletResponse response) { this.request = request; this.response = response; this.getCurUser() = WebUtil.getCurrentUser(isDebug, request); } }
在我通过JMeter,通过2个账号测试,发觉session混乱。
解决方案:
现在改成如下代码,则是可以的!
改动:
1 增加了@Autowired
2 设置curUser为private,并且封装成属性:getCurUser()
public class SuperBaseController { @Autowired protected HttpServletRequest request; @Autowired protected HttpServletResponse response; private SysUser curUser; @Value("${isDebug}") protected Boolean isDebug; @ModelAttribute public void setLang(HttpServletRequest request, HttpServletResponse response) { this.sysHostUrl = this.request.getAttribute(ComContants.SYSHOSTURL).toString(); this.sysHost = this.request.getAttribute(ComContants.SYSHOST).toString(); } public SysUser getCurUser() { curUser=WebUtil.getCurrentUser(isDebug, request); return curUser; } }
