此行为86行 request.getRequestDispatcher("phoneinfo_query.jsp").forward(request, response);

代码不完整，没法准确定位问题。
按你所说的问题，86行出现空指针。可能是 request.getRequestDispatcher("phoneinfo_query.jsp").forward(request, response);
"phoneinfo_query.jsp" 这个参数路径写错导致的。
重点是根据底下的root cause 报错显示，你这空指针也可能是
web容器内此phoneinfo_query.jsp 页面上224行上出现了空指针，建议你可以去编译路径下的classpath下查看phoneinfo_query.jsp 224行代码
