为什么我会有这种错误的行为，将电子邮件地址作为Spring MVC路径变量的值传递？[副本]

Question

在Spring MVC中使用path变量的这种特殊情况下，我发现了一些困难。

localhost:8080/my-project/utenze/my.username/confermaEmail/[e-mail]

@RequestMapping(value = "utenze/{username}/confermaEmail/{email}", method = RequestMethod.GET)
    public String confermaModificaEmail(@RequestHeader(value = HEADER_USER_CG) String codicefiscale, 
                                        @PathVariable String username, @PathVariable String email, Model model)  {

        logger.info("INTO confermaModificaEmail(), indirizzo e-mail: " + email);

        ...................................................................
        ...................................................................
        ...................................................................

        return "myView";
}

为什么？问题出在哪里？我错过了什么？我怎样才能尝试解决这个问题呢？

在您的示例中，我将从path变量中删除{email}并通过request参数请求它：

@RequestMapping(value = "utenze/{username}/confermaEmail", method = RequestMethod.GET)
public String confermaModificaEmail(@RequestHeader(value = HEADER_USER_CG) String codicefiscale, 
                                    @PathVariable String username, @RequestParam(value="email", required=true) String email, Model model)  {

    logger.info("INTO confermaModificaEmail(), indirizzo e-mail: " + email);

    ...................................................................
    ...................................................................
    ...................................................................

    return "myView";}

试一试这个=)
