Springboot学习之路--空指针异常
在开发时遇到了一个问题：
2019-08-09 21:44:31.850 ERROR 14380 — [nio-8888-exec-1] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is java.lang.NullPointerException] with root cause
java.lang.NullPointerException: null
通过断点调试后找到原因–空指针异常
解决方法：加上if语句，判断是否为空指针
if (cookies != null && cookies.length != 0)
