java - spring war 文件部署到 tomcat 9 但没有正确重定向？

Question

应用程序工作并重定向到本地机器上的 View 。

http://localhost:8080/login

一旦部署在 aws 服务器上的项目 war 文件 orbiter.war 项目正在运行并获取登录页面。

http://ec2.__compute__amazonaws.com:8080/orbiter/

登录后重定向到404 未找到的欢迎 View

http://ec2.__compute__amazonaws.com:8080/welcome

但是当我去轨道飞行器/welcome manully its redirecting.

http://ec2.__compute__amazonaws.com:8080/orbiter/welcome

登录 Controller

@RequestMapping(value = { "/", "/login" }, method = RequestMethod.GET)
public String showLoginPage() {
    return "login";
}

@RequestMapping(value = "/login", method = RequestMethod.POST)
public String handleUserLogin(ModelMap model, @RequestParam String name, @RequestParam String password) {
    return "redirect:welcome";
}

@RequestMapping(value = "/welcome", method = RequestMethod.GET)
public String showWelcomeDashboard(ModelMap model) {
    LOG.info(" Welcome to Orbiter");
    //LOG.info("User Count"+loginDao.msJdbcTest());
    //model.put("vList",null);
    return "welcome";
}

Answer 1

显然您的 url 映射不正确。

此 url 不为应用程序提供服务:

http://ec2.__compute__amazonaws.com:8080/welcome

但是这个是有效的:

http://ec2.__compute__amazonaws.com:8080/orbiter/welcome

因此请更正您的映射并将其指向orbiter/welcome， 也许您犯了一些愚蠢的错误。
