这是我的春季安全Bean

这是我的MVC-dispatcher servlet

这是我的web.xml

这是我的控制器

@Controller
@RequestMapping(value = "/c")
public class MainController {


    @RequestMapping(value = "/welcome", method = RequestMethod.GET)
    public String printWelcome(ModelMap model, Principal principal) {

        String name = principal.getName();
        model.addAttribute("username", name);
        model.addAttribute("message", "Spring Security Custom Form example");
        return "hello";

    }

    @RequestMapping(value = "/login", method = RequestMethod.GET)
    public String login(ModelMap model) {

        return "login";

    }

    @RequestMapping(value = "/loginfailed", method = RequestMethod.GET)
    public String loginerror(ModelMap model) {

        model.addAttribute("error", "true");
        return "login";

    }

    @RequestMapping(value = "/logout", method = RequestMethod.GET)
    public String logout(ModelMap model) {

        return "login";

    }
    }

我的问题是当我访问localhost：8080 / apsas / c / welcome我得到了

HTTP ERROR 500

 Server Error
java.lang.NullPointerException
    at com.apsas.controller.MainController.printWelcome(MainController.java:30)

我可以成功进入登录页面,但点击提交按钮后,我得到http错误404问题访问/ apsas / c / j_spring_security_check.

这是日志
警告：在DispatcherServlet中找不到带有URI [/ apsas / c / j_spring_security_check]的HTTP请求的映射,名称为“mvc-dispatcher”

我可以成功访问我的瓷砖中定义的一些页面,除了应该指示我登录的欢迎.请帮忙

最佳答案 默认的spring security登录页面是[application context] / j_spring_security_check

您的登录页面正在提交到/ apsas / c / j_spring_security_check.假设您的应用程序上下文是apsas,您的登录表单应该提交到/ apsas / j_spring_security_check或../j_spring_security_check.

要清楚,这是登录页面上表单元素的action属性的值.如果您需要帮助,请将登录页面发布到问题中,我可以更具体.
