java - 使用 spring mvc 将 url 模式重定向到特定 Controller

Question

我想重定向这样的请求

localhost:8080/firstSpringProject/{uniqueusername}

到名为“profile”的特定 Controller :

@RequestMapping(value="/profile")
public String profiles(Model model){

    based on the uniqueusername i would like to render a profile page 

    return "profile";
}

我正在使用 spring mvc；我该如何解决这种情况，还有其他方法吗？

Spring 文档在 redirect view 上说:

Note that URI template variables from the present request are automatically made available when expanding a redirect URL and do not need to be added explicitly neither through Model nor RedirectAttributes. For example:

@RequestMapping(value = "/files/{path}", method = RequestMethod.POST)
public String upload(...) {
    // ...
    return "redirect:files/{path}";
}

请记住，低于 3.1.4 的版本会受到 memory leak due to caching redirect views 的影响。 .

如果您使用的是 Spring 3.1.3 或更低版本并且您正在这样做

return "redirect : profile?username="+username;

你会看到OutOfMemoryError sometime .
