非常诡异的内存溢出，希望有大佬教育一波

Question

项目框架springboot2.0我写了父类BaseController里面自动注入request和response
publicclassBaseController{
@Autowired
publicHttpServletRequestrequest;
@Autowired
publicHttpServletResponseresponse;
}
IndexController都继承BaseController
publicclassIndexControllerextendsBaseController{
@RequestMapping("/index")
publicStringindex(Modelmodel){
return"index";
}
@RequestMapping("login")
publicStringlogin()throwsServletException,IOException{
request.getRequestDispatcher("/admin/index").forward(request,response);
returnnull;
}
index页面,没有任何数据操作，纯一个静态页面
TEST
访问http://localhost:9090/admin/login出现如下错误，循环引用导致内存溢出java.lang.StackOverflowError:null

1.注意看我的login就使用request转发到首页(注意，此时request和response是父类的BaseController)
注意问题不是地址循环跳引发的问题
3.使用方法注入request和response就不会有问题@RequestMapping("login")
publicStringlogin(HttpServletRequestrequest,HttpServletResponseresponse)throwsServletException,IOException{
request.getRequestDispatcher("/admin/index").forward(request,response);
returnnull;
}
有没有大佬解释一波。

你先试试接口，@RequestMapping("cc")@ResponseBodypublicObjectz(){Stringparameter=request.getParameter("zz");System.out.println(parameter);return"你好";}springboot2.0.6没有问题，先一步一步的排查，世界是科学的
