Question

在我的项目中，我的控制器中的方法具有以下结构：

@Controller
@RequestMapping(value="privado")
public class PrivadoController {

    @RequestMapping(value="admin")
    @PreAuthorize("hasPermission(#usuario, 'admin_main')")
    public ModelAndView admin() {
        ModelAndView mav = new ModelAndView();
        mav.setViewName("privado/admin");
        return mav;
    }

    @RequestMapping(value="customer")
    @PreAuthorize("hasPermission(#usuario, 'customer_main')")
    public ModelAndView customer() {
        ModelAndView mav = new ModelAndView();
        mav.setViewName("privado/customer");
        return mav;
    }

}

方法hasPermission在此CustomPermissionEvaluator类中实现：

@Component
public class CustomPermissionEvaluator implements PermissionEvaluator {

    public CustomPermissionEvaluator() {
    }

    @Override
    public boolean hasPermission(Authentication arg0, Object arg1, Object arg2) {
        System.out.println("CustomPermissionEvaluator.hasPermission");
        if (arg0 == null || !arg0.isAuthenticated())
            return false;
        else
            return arg0.getAuthorities().contains(arg1);
    }

    @Override
    public boolean hasPermission(Authentication arg0, Serializable arg1, String arg2, Object arg3) {
        throw new RuntimeException("Id-based permission evaluation not currently supported.");
    }

}

我的问题是，尽管通知正确的登录证书，并且对数据库中保存的用户具有适当的角色和权限，但我面临默认访问被拒绝页面（我的项目中有一个自定义页面用于此错误））。

任何人都能看到我在这里做错了什么？

在代码中经过仔细分析后，我终于设法解决了这个问题。碰巧我在方法体中使用了错误的参数。我的CustomPermissionEvaluator的最终代码是：

@Component
public class CustomPermissionEvaluator implements PermissionEvaluator {

    public CustomPermissionEvaluator() {
    }

    public boolean hasPermission(Authentication arg0, Object arg1) {
        System.out.println("CustomPermissionEvaluator.hasPermission");
        System.out.println("arg0 = "+arg0);
        System.out.println("arg1 = "+arg1);

        if (arg0 == null || !arg0.isAuthenticated()) {
            System.out.println("false");
            return false;
        }
        else {
            System.out.println("true");
            for(GrantedAuthority authority: arg0.getAuthorities()) {
                if(authority.getAuthority().equals(arg1))
                    return true;
            }
            return false;
        }
    }

    @Override
    public boolean hasPermission(Authentication arg0, Object arg1, Object arg2) {
        System.out.println("CustomPermissionEvaluator.hasPermission");
        System.out.println("arg0 = "+arg0);
        System.out.println("arg1 = "+arg1);
        System.out.println("arg2 = "+arg2);

        if (arg0 == null || !arg0.isAuthenticated()) {
            System.out.println("false");
            return false;
        }
        else {
            System.out.println("true");
            for(GrantedAuthority authority: arg0.getAuthorities()) {
                if(authority.getAuthority().equals(arg2))
                    return true;
            }
            return false;
        }
    }

    @Override
    public boolean hasPermission(Authentication arg0, Serializable arg1, String arg2, Object arg3) {
        throw new RuntimeException("Id-based permission evaluation not currently supported.");
    }

}

使用Spring Security的hasPermission时拒绝访问页面
