Spring框架，PreAuthorize控件中的自定义函数

Question

我是春天新手，我正在努力学习开发一个简单的应用程序。

这是数据库的架构： http://i.imgur.com/69czuV5.png

非常简单，每个用户必须从登录开始，一旦他们这样做，就会显示管理员所在团队的列表。该信息存储在表 team_members

中

INSERT INTO team_members (user_id, team_id, role) VALUES ('1', '1', 'admin');
INSERT INTO team_members (user_id, team_id, role) VALUES ('1', '2', 'admin');
INSERT INTO team_members (user_id, team_id, role) VALUES ('2', '2', 'player');
INSERT INTO team_members (user_id, team_id, role) VALUES ('2', '3', 'admin');

当用户尝试编辑或访问页面以编辑其中一个团队时，我的问题就出现了。这是我的控制器：

@RequestMapping(value="teams/{id}/edit", method=RequestMethod.GET)
    public ModelAndView editTeamPage(@PathVariable Integer id) {
        ModelAndView modelAndView = new ModelAndView("edit-team-form");
        Team team = teamService.getTeam(id);
        modelAndView.addObject("team",team);
        return modelAndView;
    }

为了能够访问此页面，必须对此用户进行身份验证isAuthenticated()，但是，我还要检查表中 team_members中用户的角色 是 admin 。
所以我的问题是，最好的方法是什么？我应该在每个必须验证这种情况的控制器功能的开始时插入 if 吗？对此有更清洁的解决方案吗？

我试图创建

package com.sports.beans;

import org.springframework.stereotype.Component;

@Component("mySecurityService")
public class MySecurityService {

    public boolean hasPermission(String key) {
        return false;
    }
}

并将@PreAuthorize("@mySecurityService.hasPermission('special')")添加到控制器功能但它没有工作。编辑：方法mySecurityService.hasPermission（...）未被调用

这是我的spring-security.xml

Answer 1

为了让@PreAuthorize影响代码，您需要确保enable method security。例如：

<global-method-security pre-post-annotations="enabled" />

常见问题是用户将在其控制器上定义安全注释，在父上下文中定义global-method-security元素。这不起作用。

global-method-security元素必须在与您尝试保护的资源相同的Spring Context中定义。因此，例如，如果根ApplicationContext定义了您尝试保护的服务bean，那么它还应该引用包含global-method-security的配置。

对于您的示例，这可能意味着应该通过web.xml中的以下内容选择所有配置：

<context-param>  
    <param-name>contextConfigLocation</param-name>  
    <param-value>  
        /WEB-INF/spring-database.xml,  
        /WEB-INF/spring-security.xml  
    </param-value>  
</context-param>
