Spring Security 简单应用

Question

您好，我是 Spring Security 的新手，但我在使用 Spring 方面有一些经验，我按照 mkyong.com 网站上的教程在 Spring 3.07 中创建简单的应用程序，效果很好 但是当我尝试添加注释“@secured ('ROLE_ADMIN')”时，我发现错误“无法创建 loginCOntroller bean” 任何人都可以指出错误或为我提供简单的弹簧安全应用程序 这是我的代码

logincontroller.java

    @Controller
public class LoginController {

    @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";

    }

    // @Secured("ROLE_ADMIN")
     @RequestMapping(value="/delete", method = RequestMethod.GET)
    public String DeleteAll(ModelMap model, Principal principal ) {
        return "deleteUsers";
    }

    @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";

    }

    }

当前状态下的代码成功执行，但是当我删除 @Secured('ROLE_ADMIN') 代码的注释时显示错误无法创建登录控制器 bean 谁能告诉我我缺少什么或提供简单的 Spring SEcurity 应用程序的代码

Answer 1

对我来说没问题。但我使用的是 3.1.0.RELEASE 而不是 3.0.7。另外，请检查您的进口。应该是 import org.springframework.security.access.annotation.Secured;

Answer 2

只需使用这个：@Secured({"ROLE_ADMIN"})
