SpringBoot+Shiro+JWT前后端分离实现用户权限和接口权限控制

1. 引入需要的依赖

我使用的是原生jwt的依赖包，在maven仓库中有好多衍生的jwt依赖包，可自己在maven仓库中选择，实现大同小异。

　　　　<dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-web</artifactId>
            <version>${shiro.version}</version>
            <scope>compile</scope>
        </dependency>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-spring</artifactId>
            <version>${shiro.version}</version>
        </dependency>
        <dependency>
            <groupId>org.crazycake</groupId>
            <artifactId>shiro-redis</artifactId>
            <version>${shiro-redis.version}</version>
            <exclusions>
                <exclusion>
                    <artifactId>shiro-core</artifactId>
                    <groupId>org.apache.shiro</groupId>
                </exclusion>
            </exclusions>
        </dependency>
        <!--JWT依赖-->
        <dependency>
            <groupId>com.auth0</groupId>
            <artifactId>java-jwt</artifactId>
            <version>${jwt.version}</version>
        </dependency>

2. 配置shiro信息

2.1. 配置文件增加属性值配置

# shiro 配置
shiro:
  filter-chain-map:
    # 用户登录
    '[/login/**]': origin
    # 获取api token
    '[/api/token/**]': anon
    # api接口权限配置
    '[/api/**]': api
    # 用户权限控制
    '[/**]': origin, jwt
  # 设置权限缓存时间
  cache-timeout: 60

2.2. shiro 配置类

        authInfo.addStringPermissions(permissionList);
        return authInfo;

}

说明

1. MyReam类中用到了@Lazy注解，该注解的作用是：增加@Lazy注解 是TokenService为低优先级注入的bean,为防止项目启动时报Bean 'xxx' of type [com.xx.xxx.xxxx.xxxxx$$EnhancerBySpringCGLIB$$babebd0] is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying)
关于权限的设置，如果权限存在包含关系，那么配置了大范围的权限后，即使没有配置范围小的权限，也是可以访问的。比如：父菜单-用户权限管理，对应权限编码为：demo:user:auth；功能菜单用户管理查询对应权限编码为：demo:user:auth:query；那么配置了demo:user:auth后，即使没有配置demo:user:auth:query，去访问相应的带权限查询接口的时候依然可以访问到。避免上述问题的解决方案具体操作如下：
1. 父菜单-用户权限管理，对应权限编码为：demo:user:auth:manager；子菜单-用户管理查询，对应权限编码为：demo:user:auth:query
2. 查询菜单的时候排除掉 父菜单-用户权限管理这种非功能性菜单权限

3. 测试

3.1. 登录测试

POST http://localhost:6666/login
Content-Type: application/json;utf-8

Body
{"account": "admin", "password": "admin"}

返回数据
{"ret":0,"code":0,"msg":"success","data":"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJ1c2VyIiwiYXVkIjoidXNlciIsIm5iZiI6MTU5NTIyNzg5MywiaXNzIjoiYWRtaW4iLCJpYXQiOjE1OTUyMjc4OTMsImFjY291bnQiOiJhZG1pbiIsImp0aSI6ImExYjEyYjkyLWM1YjQtNGRmZC05ZjI5LWNjNTRiOGNkZjU4YyJ9.H4SGEHKo6f9SwrRYEYacKKJfR9GxKhYFO3zGmCv_f5k"}

3.2. 用户查询（权限编码：demo:user:query）

GET http://localhost:6666/user/query
Authorization: eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJ1c2VyIiwiYXVkIjoidXNlciIsIm5iZiI6MTU5NTIyNzg5MywiaXNzIjoiYWRtaW4iLCJpYXQiOjE1OTUyMjc4OTMsImFjY291bnQiOiJhZG1pbiIsImp0aSI6ImExYjEyYjkyLWM1YjQtNGRmZC05ZjI5LWNjNTRiOGNkZjU4YyJ9.H4SGEHKo6f9SwrRYEYacKKJfR9GxKhYFO3zGmCv_f5k
