Java Spring框架，控制器预授权中的自定义函数

我是spring的新手，我正在努力学习如何开发一个简单的应用程序

这是数据库的架构：

这非常简单，每个用户都必须先登录，一旦登录，就会显示一个团队列表，其中有管理员。该信息存储在表team_members中

当用户试图编辑或访问要编辑其中一个团队的页面时，就会出现我的问题。这是我的控制器来执行此操作：

@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，必须对该用户进行身份验证和身份验证，但是，我还想检查该用户在team_members表中的角色是否为admin。 所以我的问题是，最好的方法是什么？我是否应该在每个必须验证此条件的控制器函数中插入if？有没有更清洁的解决方案

我试图创造

package com.sports.beans;

import org.springframework.stereotype.Component;

@Component("mySecurityService")
public class MySecurityService {

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

---

并补充说@PreAuthorize@mySecurityService.hasPermission控制器功能“特殊”，但它不起作用。编辑：方法mySecurityService.hasPermission。。。不叫

这是我的spring-security.xml

spring-database.xml

为了让@PreAuthorize影响代码，您需要确保。例如：

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

一个常见的问题是，用户将在其控制器上定义安全注释，并在父上下文中定义全局方法安全元素。这是行不通的

全局方法安全元素必须在与您试图保护的资源相同的Spring上下文中定义。因此，例如，如果根ApplicationContext定义了您试图保护的服务bean，那么它还应该引用包含全局方法安全性的配置

对于您的示例，这可能意味着所有配置都应该由web.xml中的以下内容获取：

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

你说它不起作用是什么意思@PreAuthorize@mySecurityService.hasPermission“特殊”应该可以工作，但是您没有传递检查所需的登录用户id，例如@PreAuthorize@mySecurityService.hasPermissionprincipal“管理员”。当然，您的服务方法需要hasPermissionUserDetails用户，字符串键。方法mySecurityService.hasPermission。。。未调用。可能是配置文件的顺序，请参阅
