Answer 1

@RequestMapping(value = { "/", "/home","/Insurance1/" }, method = RequestMethod.GET)

我认为，您应该将其更改为

@RequestMapping(value = { "/", "/home","/Insurance1" }, method = RequestMethod.GET)

Answer 2

假设您的应用程序的上下文名称为/abc且服务器运行的端口为XXXX，请尝试向http://localhost:XXXX/abc/Insurance1/发送请求。只需将'XXXX'替换为运行tomcat的实际端口号，并将'abc'替换为应用程序的实际上下文。让我知道它是否有帮助。
