java - Spring框架， Controller PreAuthorize中自定义函数

标签 java spring spring-mvc spring-security

我是 Spring 新手，我正在尝试学习开发一个简单的应用程序。

这是数据库的架构: /image/3H4jd.png

非常简单，每个用户都必须首先登录，一旦登录，就会显示管理员所在的团队列表。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要编辑其中一个团队的页面时，就会出现问题。这是我的 Controller 来执行此操作:

@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，该用户必须经过身份验证 isAuthenticated()，但是，我还想检查表 team_members 中用户的角色是否为admin。
所以我的问题是，最好的方法是什么？我是否应该在必须验证此条件的每个 Controller 函数的开头插入一个 if ？有没有更清洁的解决方案？

我尝试创建

package com.sports.beans;

import org.springframework.stereotype.Component;

@Component("mySecurityService")
public class MySecurityService {

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

并向 Controller 函数添加了 @PreAuthorize("@mySecurityService.hasPermission('special')") 但它不起作用。编辑:未调用方法 mySecurityService.hasPermission(...)

这是我的spring-security.xml

最佳答案

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" />

一个常见的问题是用户将在其 Controller 上定义安全注释以及父上下文中的 global-method-security 元素。这是行不通的。

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

对于您的示例，这可能意味着所有配置都应由 web.xml 中的以下内容选取:

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