Shiro实战2-Springboot集成Shiro实战

说明

最近打算打造一个简易的权限管理系统，打算用shiro做认证和授权。本篇作为springboot集成shiro的入门实战案例记录下来，希望也可以帮到大家，代码整理自网络。

• 技术栈
  springboot+shiro+thymeleaf+mysql

添加pom依赖

<dependency>
     <groupId>org.apache.shiro</groupId>
     <artifactId>shiro-spring</artifactId>
     <version>1.5.3</version>
 </dependency>
 <dependency>
     <groupId>com.github.theborakompanioni</groupId>
     <artifactId>thymeleaf-extras-shiro</artifactId>
     <version>2.0.0</version>
 </dependency>

定义用户权限模型

@Data
public class Account {
    private Integer id;
    private String username;
    private String password;
    // 权限
    private String perms;
    // 角色
    private String role;
}

• 对应表中数据：
  

自定义realm

public class AccoutRealm extends AuthorizingRealm {

    @Autowired
    private AccountService accountService;

    /**
     * 授权
     * @param principalCollection
     * @return
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        //获取当前登录的用户信息
        Subject subject = SecurityUtils.getSubject();
        Account account = (Account) subject.getPrincipal();

        //设置角色
        Set<String> roles = new HashSet<>();
        roles.add(account.getRole());
        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo(roles);

        //设置权限
        info.addStringPermission(account.getPerms());
        return info;
    }


    /**
     * 认证
     * @param authenticationToken
     * @return
     * @throws AuthenticationException
     */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        UsernamePasswordToken token = (UsernamePasswordToken) authenticationToken;
        Account account = accountService.findByUsername(token.getUsername());
        if(account != null){
            return new SimpleAuthenticationInfo(account,account.getPassword(),getName());
        }
        return null;
    }
}

自定义shiro-config

@Configuration
public class ShiroConfig {

    @Bean
    public ShiroFilterFactoryBean shiroFilterFactoryBean(@Qualifier("securityManager") DefaultWebSecurityManager securityManager){
        ShiroFilterFactoryBean factoryBean = new ShiroFilterFactoryBean();
        factoryBean.setSecurityManager(securityManager);
        //权限设置
        Map<String,String> map = new Hashtable<>();
        map.put("/main","authc");
        map.put("/manage","perms[manage]");
        map.put("/administrator","roles[administrator]");
        factoryBean.setFilterChainDefinitionMap(map);
        //设置登录页面
        factoryBean.setLoginUrl("/login");
        //设置未授权页面
        factoryBean.setUnauthorizedUrl("/unauth");
        return factoryBean;
    }


    @Bean
    public DefaultWebSecurityManager securityManager(@Qualifier("accoutRealm") AccoutRealm accoutRealm){
        DefaultWebSecurityManager manager = new DefaultWebSecurityManager();
        manager.setRealm(accoutRealm);
        return manager;
    }

    @Bean
    public AccoutRealm accoutRealm(){
        return new AccoutRealm();
    }

    @Bean
    public ShiroDialect shiroDialect(){
        return new ShiroDialect();
    }
}

创建登录控制器

@Controller
public class AccountController {

    @GetMapping("/{url}")
    public String redirect(@PathVariable("url") String url){
        return url;
    }

    @PostMapping("/login")
    public String login(String username, String password, Model model){
        Subject subject = SecurityUtils.getSubject();
        UsernamePasswordToken token = new UsernamePasswordToken(username,password);
        try {
            subject.login(token);
            Account account = (Account) subject.getPrincipal();
            subject.getSession().setAttribute("account",account);
            return "index";
        } catch (UnknownAccountException e) {
            e.printStackTrace();
            model.addAttribute("msg","用户名错误！");
            return "login";
        } catch (IncorrectCredentialsException e){
            model.addAttribute("msg","密码错误！");
            e.printStackTrace();
            return "login";
        }
    }

    @GetMapping("/unauth")
    @ResponseBody
    public String unauth(){
        return "未授权，无法访问！";
    }

    @GetMapping("/logout")
    public String logout(){
        Subject subject = SecurityUtils.getSubject();
        subject.logout();
        return "login";
    }
}

创建页面

• index.html

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org" xmlns:shiro="http://www.thymeleaf.org/thymeleaf-extras-shiro">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <link rel="shortcut icon" href="#"/>
</head>
<body>
    <h1>index</h1>
    <div th:if="${session.account != null}">
        <span th:text="${session.account.username}+'欢迎回来！'"></span><a href="/logout">退出</a>
    </div>
    <a href="/main">main</a> <br/>
    <div shiro:hasPermission="manage">
        <a href="manage">manage</a> <br/>
    </div>
    <div shiro:hasRole="administrator">
        <a href="/administrator">administrator</a>
    </div>
</body>
</html>

• login.html

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <link rel="shortcut icon" href="#"/>
</head>
<body>
    <form action="/login" method="post">
        <table>
            <span th:text="${msg}" style="color: red"></span>
            <tr>
                <td>用户名：</td>
                <td>
                    <input type="text" name="username"/>
                </td>
            </tr>
            <tr>
                <td>密码：</td>
                <td>
                    <input type="password" name="password"/>
                </td>
            </tr>
            <tr>
                <td>
                    <input type="submit" value="登录"/>
                </td>
            </tr>
        </table>
    </form>
</body>
</html>

测试

实现的效果

1.访问根路径跳转到index.html
2.访问main页面跳转到登录页
3.登录成功后跳转到首页，根据用户拥有的角色和权限展示不通功能模块
