Java Spring找不到网址

java spring model

Java Spring找不到网址,java,spring,model,Java,Spring,Model,我正在尝试加载这个特定的JSP/url。但当它执行时，我得到以下错误找不到此本地主机页找不到该网址的网页：http://localhost:8181/home HTTP错误404 这是我的安全配置 .permitAll() .and().formLogin() // to show the page where we enter login credentials .loginPage("/login&

我正在尝试加载这个特定的JSP/url。但当它执行时，我得到以下错误

找不到此本地主机页找不到该网址的网页：http://localhost:8181/home HTTP错误404

这是我的安全配置

        .permitAll()
        .and().formLogin()
            // to show the page where we enter login credentials 
            .loginPage("/login") 
            // to process authentication: /login handler method implemented by Spring Security
            .loginProcessingUrl("/mylogin")
            // where to go after successful login
            .defaultSuccessUrl("/success", true)
            // to show an error page if the authentication failed
            .failureUrl("/login?Error=True")
            // everyone can access these requests
            .permitAll()

因此，当它成功时，它会转到url“/success”。这是下面的请求映射

@RequestMapping(value = "/success", method = RequestMethod.GET)
public String successLogin(Principal p) {
    System.out.println("Shalom56765");
    Volunteer user = volRepo.findByEmail(p.getName());
    if (user.getKind().equals(UserKind.Admin)) {
        return "/admin";
    }
    if (user.getKind().equals(UserKind.user)) {
        System.out.println("user is a user");
        return "redirect:/home";
    }

    return "login";
}}

以及“/home”的映射

但我得到的错误是它找不到“/家”我该做的是任何人看到一个我看不到的简单错误。谢谢各位。杰夫

确保它是在端口8181上运行的你的应用程序，如果碰巧有另一个应用程序在端口8181上运行，而你在另一个端口上运行，如果你想让我们帮助你找到它，你可以得到一个404错误，发布整个控制器可能会有帮助我会添加整个控制器代码，它在端口8181上运行谢谢你的回复，我现在收到这个错误mo.s.web.servlet.PageNotFound请求方法'GET'不受支持Cheers mare我删除了@RequestBody，它成功了
