最近在做一个期末作品,就是应用 ssm+thymeleaf+vue+shiro 实现一个具备 权限登录,且能实现用户信息增删查改 的这么一个我的项目,上面仅仅是实现 权限认证和登录。为什么我选 shiro,而不选 spring Security,是因为我试过,security 切实是比拟难,封装的太厉害了,哈哈哈哈,所以果决放弃,抉择 shiro 进行。

下一篇还实现了增删查改,应用 vue,然而没有前后端拆散,博客链接

!github 源码连贯,须要请自行下载。

提醒,这个我的项目曾经有了增删查改,跟着上面的博客做,也能做进去页面跳转权限,然而没有增删查改。

以下是学习 shiro 的一个小 Demo:

1. 首先是底层数据库:

-- ----------------------------
-- Table structure for role
-- ----------------------------
CREATE TABLE `role`  (`id` int(11) NOT NULL AUTO_INCREMENT COMMENT '角色表主键',
  `role_name` varchar(32) DEFAULT NULL COMMENT '角色名称',
  PRIMARY KEY (`id`)
);

-- ----------------------------
-- Records of role
-- ----------------------------
INSERT INTO `role` VALUES (1, 'SUPER_ADMIN');
INSERT INTO `role` VALUES (2, 'ADMIN');
INSERT INTO `role` VALUES (3, 'USER');

-- ----------------------------
-- Table structure for user
-- ----------------------------
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user`  (`id` int(11) NOT NULL AUTO_INCREMENT COMMENT '用户主键',
  `username` varchar(32) NOT NULL COMMENT '用户名',
  `password` varchar(32) NOT NULL COMMENT '明码',
  `role_id` int(11) DEFAULT NULL COMMENT '与 role 角色表分割的外键',
  PRIMARY KEY (`id`),
  CONSTRAINT `user_role_on_role_id` FOREIGN KEY (`role_id`) REFERENCES `role` (`id`)
);

-- ----------------------------
-- Records of user
-- ----------------------------
INSERT INTO `user` VALUES (1, 'BWH_Steven', '666666', 1);
INSERT INTO `user` VALUES (2, 'admin', '666666', 2);
INSERT INTO `user` VALUES (3, 'zhangsan', '666666', 3);

-- ----------------------------
-- Table structure for permission
-- ----------------------------
CREATE TABLE `permission`  (`id` int(11) NOT NULL AUTO_INCREMENT COMMENT '权限表主键',
  `permission_name` varchar(50) NOT NULL COMMENT '权限名',
  `role_id` int(11) DEFAULT NULL COMMENT '与 role 角色表分割的外键',
  PRIMARY KEY (`id`),
  CONSTRAINT `permission_role_on_role_id` FOREIGN KEY (`role_id`) REFERENCES `role` (`id`)
);

-- ----------------------------
-- Records of permission
-- ----------------------------
INSERT INTO `permission` VALUES (1, 'user:*', 1);
INSERT INTO `permission` VALUES (2, 'user:*', 2);
INSERT INTO `permission` VALUES (3, 'user:queryAll', 3);

2. 创立 spring boot 我的项目,用 maven 构建

创立实体类(User,Role,Permissions):
User:

@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {
    private Integer id;
    private String username;
    private String password;
    // 用户对应的角色汇合
    private Role role;
}

Role:

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Role {
    private Integer id;
    private String roleName;


}

Permissions:

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Permissions {
    private Integer id;
    private String permissionName;
    private Role role;
}

咱们须要晓得三个实体类之间的关系,User 与 Role 一对一,Role 与 Permissions 一对一,当然也能够把它都写成多对多,这就须要去更改数据库文件,和实体类了。

3. 在 pom.xml 增加相干依赖:

上面只给出相干依赖源

                </exclusion>
            </exclusions>
        </dependency>

4. 整合 mybatis 和 springboot:

就只须要创立一个 dao 层,一个服务层, 须要记住要 增加注解
(1)mapper 配置文件(也能够应用注解模式):

<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.example.csy.dao.UserMapper">

    <select id="queryUserByUsername" resultMap="userRoleMap">
        SELECT u.*,r.role_name FROM `user` u, `role` r
          WHERE username = #{username} AND u.role_id = r.id;
    </select>
    <!-- 定义封装 User 和 role 的 resultMap -->
    <resultMap id="userRoleMap" type="com.example.csy.entity.User">
        <id property="id" column="id"/>
        <result property="username" column="username"></result>
        <result property="password" column="password"></result>
        <!-- 配置封装 UserPojo 的内容 -->
        <association property="role" javaType="com.example.csy.entity.Role">
            <id property="id" column="id"></id>
            <result property="roleName" column="role_name"></result>
        </association>
    </resultMap>


    <select id="queryPermissionByUsername" resultMap="permissionRoleMap">
        SELECT p.* ,r.role_name FROM `user` u, `role` r, `permission` p
          WHERE username = #{username} AND u.role_id = r.id AND p.role_id = r.id;
    </select>
    <!-- 定义封装 permission 和 role 的 resultMap -->
    <resultMap id="permissionRoleMap" type="com.example.csy.entity.Permissions">
        <id property="id" column="id"/>
        <result property="permissionName" column="permission_name"></result>
        <!-- 配置封装 Role 的内容 -->
        <association property="role" javaType="com.example.csy.entity.Role">
            <id property="id" column="id"></id>
            <!--property 是实体类中被赋值的参数名,column 是数据库的列名 -->
            <result property="roleName" column="role_name"></result>
        </association>
    </resultMap>
</mapper>

(2)DAO 层:

@Mapper
public interface UserMapper {User queryUserByUsername(@Param("username") String username);

    Permissions queryPermissionByUsername(@Param("username") String username);
}

(3)service 层:


@Service
public class UserServiceImpl implements UserService {
    @Autowired
    private UserMapper userMapper;

    @Override
    public User queryUserByUsername(String username) {return userMapper.queryUserByUsername(username);
    }

    @Override
    public Permissions queryPermissionByUsername(String username) {return userMapper.queryPermissionByUsername(username);
    }
}

弄到这里,咱们的 mybatis+springboot 整合也根本完结,所以在测试类里测试一下:

@SpringBootTest
class CsyApplicationTests {

    @Autowired
    private UserMapper userMapper;

    @Test
    void contextLoads() {User admin = userMapper.queryUserByUsername("admin");
        System.out.println(admin.toString());
        Permissions permission = userMapper.queryPermissionByUsername("admin");
        System.out.println(permission.toString());
    }
}

测试后果:
失去了查问后果

6. 整合 Thymeleaf 进来:

前端页面:
在 html 页面咱们整合了 Thymeleaf,应用了 Jquery,semantic,须要导包

index.html 代码:
在这里,如果是 User 就只能拜访 A,Admin 能拜访 A,B,superAdmin 能拜访 A,B,C

7. 将 shiro 整合到我的项目里:

(1)自定义 Realm:

咱们须要自定义,认证和受权:

public class UserRealm extends AuthorizingRealm {

    @Autowired
    private UserMapper userMapper;

    /**
     * @MethodName doGetAuthorizationInfo 受权操作
     * @Description 权限配置类
     * @Param [principalCollection]
     * @Return AuthorizationInfo
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        // 获取用户名信息
        String username = (String) principalCollection.getPrimaryPrincipal();
        // 创立一个简略受权验证信息
        SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
        // 给这个用户设置从 role 表获取到的角色信息
        authorizationInfo.addRole(userMapper.queryUserByUsername(username).getRole().getRoleName());
        // 给这个用户设置从 permission 表获取的权限信息
        authorizationInfo.addStringPermission(userMapper.queryPermissionByUsername(username).getPermissionName());
        return authorizationInfo;
    }

    /**
     * @MethodName doGetAuthenticationInfo 身份验证
     * @Description 认证配置类
     * @Param [authenticationToken]
     * @Return AuthenticationInfo
     * @Author WangShiLin
     */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        // 依据在承受前台数据创立的 Token 获取用户名
        String username = (String) authenticationToken.getPrincipal();

//        UsernamePasswordToken userToken = (UsernamePasswordToken) authenticationToken;
//        System.out.println(userToken.getPrincipal());
//        System.out.println(userToken.getUsername());
//        System.out.println(userToken.getPassword());

        // 通过用户名查问相干的用户信息(实体)User user = userMapper.queryUserByUsername(username);
        if (user != null) {
            // 存入 Session,可选
            SecurityUtils.getSubject().getSession().setAttribute("user", user);
            // 明码认证的工作,Shiro 来做
            AuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(), "userRealm");
            return authenticationInfo;
        } else {
            // 返回 null 即会抛异样
            return null;
        }
    }
}

(2)写配置类 shiroConfig:

@Configuration
public class ShiroConfig {

    // 将本人的验证形式退出容器
    @Bean
    public UserRealm myShiroRealm() {return new UserRealm();
    }

    /**
     * 配置平安管理器 SecurityManager
     *
     * @return
     */
    @Bean
    public DefaultWebSecurityManager securityManager() {
        // 将自定义 Realm 加进来
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        // 关联 Realm
        securityManager.setRealm(myShiroRealm());
        return securityManager;
    }

    /**
     * 配置 Shiro 过滤器
     *
     * @param securityManager
     * @return
     */
    @Bean
    public ShiroFilterFactoryBean shiroFilter(DefaultWebSecurityManager securityManager) {
        // 定义 shiroFactoryBean
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();

        // 关联 securityManager
        shiroFilterFactoryBean.setSecurityManager(securityManager);

        // 自定义登录页面,如果登录的时候,就会执行这个申请,即跳转到登录页
        shiroFilterFactoryBean.setLoginUrl("toLoginPage");
        // 指定胜利页面
        shiroFilterFactoryBean.setSuccessUrl("/success");
        // 指定未受权界面
        shiroFilterFactoryBean.setUnauthorizedUrl("/unauthorized");

        // 设置自定义 filter
        Map<String, Filter> filterMap = new LinkedHashMap<>();
        filterMap.put("anyRoleFilter", new MyRolesAuthorizationFilter());
        shiroFilterFactoryBean.setFilters(filterMap);

        // LinkedHashMap 是有序的,进行程序拦截器配置
        Map<String, String> filterChainMap = new LinkedHashMap<>();

        // 配置能够匿名拜访的地址,能够依据理论状况本人增加,放行一些动态资源等,anon 示意放行
        filterChainMap.put("/css/**", "anon");
        filterChainMap.put("/img/**", "anon");
        filterChainMap.put("/js/**", "anon");
        // 指定页面放行,例如登录页面容许所有人登录
        filterChainMap.put("/toLoginPage", "anon");

        // 以“/user/admin”结尾的用户须要身份认证,authc 示意要进行身份认证
        filterChainMap.put("/user/admin/**", "authc");

        // 页面 - 用户须要角色认证
        filterChainMap.put("/levelA/**", "anyRoleFilter[USER,ADMIN,SUPER_ADMIN]");
        filterChainMap.put("/levelB/**", "anyRoleFilter[ADMIN,SUPER_ADMIN]");
        filterChainMap.put("/levelC/**", "anyRoleFilter[SUPER_ADMIN]");

//        filterChainMap.put("/levelA/**", "roles[USER]");
//        filterChainMap.put("/levelB/**", "roles[ADMIN]");
//        filterChainMap.put("/levelC/**", "roles[SUPER_ADMIN]");

        // /user/admin/ 下的所有申请都要通过权限认证,只有权限为 user:[*] 的能够拜访,也能够具体设置到 user:xxx
        filterChainMap.put("/user/admin/**", "perms[user:*]");

        // 配置登记过滤器
        filterChainMap.put("/logout", "logout");

        // 将 Map 存入过滤器
        shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainMap);
        return shiroFilterFactoryBean;
    }

    /**
     * 整合 thymeleaf
     * @return
     */
    @Bean(name = "shiroDialect")
    public ShiroDialect shiroDialect(){return new ShiroDialect();

    }


首先咱们将自定义的 Realm 办法,依赖注入进来到容器

// 将本人的验证形式退出容器
    @Bean
    public UserRealm myShiroRealm() {return new UserRealm();
    }

而后是:SecurityManager 配置平安管理器

/**
     * 配置平安管理器 SecurityManager
     *
     * @return
     */
    @Bean
    public DefaultWebSecurityManager securityManager() {
        // 将自定义 Realm 加进来
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        // 关联 Realm
        securityManager.setRealm(myShiroRealm());
        return securityManager;
    }

最初就是自定义的过滤器,管制那些页面须要什么样的角色能力拜访,哪些资源须要谁能力拜访,并且 setSecurityManager,返回一个 ShiroFilterFactoryBean。

重点说一下拦挡放行(Map)这块:通过 map 键值对的模式存储,key 存储 URL,value 存储对应的一些权限或者角色等等,其实 key 这块还是很好了解的,例如:/css/、/user/admin/ 别离代表 css 文件夹下的所有文件,以及申请门路前缀为 /user/admin/ URL,而对应的 value 就有肯定的标准了。

要害:
anon:无需认证,即可拜访,也就是游客也能够拜访
authc:必须认证,能力拜访,也就是例如须要登录后
roles[xxx]:比方领有某种角色身份能力拜访,注:xxx 为角色参数
perms[xxx]:必须领有对某个申请、资源的相干权限能力拜访,注:xxx 为权限参数

(3)自定义一个角色认证过滤器 MyRolesAuthorizationFilter:

因为咱们的角色,只需用有一个角色就能拜访到映射页面,shiro 默认是 hasAllRoles,也就是说,咱们要满足所有的身份能力拜访,所以须要咱们自定义一个 hasAnyRoles,任选其一角色即可。

public class MyRolesAuthorizationFilter extends AuthorizationFilter {@SuppressWarnings({"unchecked"})
    public boolean isAccessAllowed(ServletRequest request, ServletResponse response, Object mappedValue) throws IOException {Subject subject = getSubject(request, response);
        String[] rolesArray = (String[]) mappedValue;

        if (rolesArray == null || rolesArray.length == 0) {
            //no roles specified, so nothing to check - allow access.
            return false;
        }

        List<String> roles = CollectionUtils.asList(rolesArray);
        boolean[] hasRoles = subject.hasRoles(roles);
        for (boolean hasRole : hasRoles) {if (hasRole) {return true;}
        }
        return false;
    }
}

(4)最初就是 controller

controller 是 springMvc 的前端控制器,接管什么申请,并且返回对应指定的页面(映射)。
首先咱们先将所以页面的映射写好,

PageController:

@Controller
public class PageController {@RequestMapping({"/", "index"})
    public String index() {return "index";}

    @RequestMapping("about")
    public String toAboutPage() {return "redirect:http://www.ideal-20.cn";}

    @RequestMapping("/toLoginPage")
    public String toLoginPage() {return "views/login";}

    @RequestMapping("/levelA/{name}")
    public String toLevelAPage(@PathVariable("name") String name) {return "views/L-A/" + name;}

    @RequestMapping("/levelB/{name}")
    public String toLevelBPage(@PathVariable("name") String name) {return "views/L-B/" + name;}

    @RequestMapping("/levelC/{name}")
    public String toLevelCPage(@PathVariable("name") String name) {return "views/L-C/" + name;}

    @RequestMapping("/unauthorized")
    public String toUnauthorizedPage() {return "views/unauthorized";}

    @RequestMapping("/success")
    public String toSuccessPage() {return "views/success";}

}

UserController:
下面那两个映射,只是测试,次要是那个 login 办法,他能够依据咱们前台输出的数据,并创立一个 token,如果该 token 能被认证,即返回胜利页面,否则就失败。

@Controller
public class UserController {@RequestMapping("/user/queryAll")
    @ResponseBody
    public String queryAll() {return "这是 user/queryAll 办法";}

    @RequestMapping("/user/admin/add")
    @ResponseBody
    public String adminAdd() {return "这是 user/adminAdd 办法";}

    @RequestMapping("/login")
    public String login(String username, String password, HttpServletRequest request) {
        // 因为是依据 name 参数获取的,我这里封装了一下
        User user = new User();
        user.setUsername(username);
        user.setPassword(password);

        // 创立出一个 Token 内容实质基于前台的用户名和明码(不肯定正确)UsernamePasswordToken token = new UsernamePasswordToken(username, password);
        // 获取 subject 认证主体(这里也就是当初登录的用户)Subject subject = SecurityUtils.getSubject();
        try{
            // 认证开始,这里会跳转到自定义的 UserRealm 中
            subject.login(token);
            // 能够存储到 session 中
            request.getSession().setAttribute("user", user);
            return "views/success";
        }catch(Exception e){
            // 捕捉异样
            e.printStackTrace();
            request.getSession().setAttribute("user", user);
            request.setAttribute("errorMsg", "兄弟,用户名或明码谬误");
            return "views/login";
        }
    }
}

8. 最终成果:

首先是 http://localhost:8080/index

登录界面:

表单提交后,就返回值到 UserController 那个 Login 办法,认证:

这样咱们就登录胜利了,并且是 superAdmin 的权限,能够查看 A,B,C

而用户张三,只能看见 A
