spring集成hbase如何进行权限管理

在Spring集成HBase时，可以使用Apache Shiro进行权限管理。Shiro是一个强大且易于使用的Java安全框架，提供了认证、授权、加密和会话管理等功能。以下是在Spring集成HBase中使用Shiro进行权限管理的步骤：

1. 添加依赖

在项目的pom.xml文件中添加Shiro和HBase相关的依赖：

    org.apache.shiro
    shiro-core
    1.7.1


    org.apache.shiro
    shiro-spring
    1.7.1


    org.apache.hadoop
    hadoop-client
    3.3.1

2. 配置Shiro

创建一个Shiro配置类，例如ShiroConfig.java，并配置Shiro的相关组件，如SecurityManager、Realm等。在这个类中，你需要配置HBase的连接信息以及Shiro的过滤器。

@Configuration
public class ShiroConfig {

    @Bean
    public DefaultWebSecurityManager securityManager(HBaseRealm hBaseRealm) {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setRealm(hbaseRealm);
        return securityManager;
    }

    @Bean
    public HBaseRealm hBaseRealm() {
        return new HBaseRealm();
    }

    @Bean
    public ShiroFilterFactoryBean shiroFilterFactoryBean(DefaultWebSecurityManager securityManager) {
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        shiroFilterFactoryBean.setSecurityManager(securityManager);

        // 配置过滤器
        Map filters = new LinkedHashMap<>();
        filters.put("authc", new HBaseAuthenticationFilter());
        filters.put("user", new HBaseUserFilter());
        filters.put("roles", new HBaseRolesFilter());
        filters.put("permissions", new HBasePermissionsFilter());
        shiroFilterFactoryBean.setFilters(filters);

        // 配置过滤器链
        Map filterChainDefinitionMap = new LinkedHashMap<>();
        filterChainDefinitionMap.put("/hbase/**", "authc");
        filterChainDefinitionMap.put("/**", "user");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);

        return shiroFilterFactoryBean;
    }
}

3. 创建HBaseRealm

创建一个实现org.apache.shiro.realm.AuthorizingRealm接口的类，例如HBaseRealm.java。在这个类中，你需要实现doGetAuthenticationInfo和doGetAuthorizationInfo方法，分别用于认证和授权。

public class HBaseRealm extends AuthorizingRealm {

    @Autowired
    private HBaseConnectionFactory hBaseConnectionFactory;

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        // 获取用户名和密码
        String username = (String) token.getPrincipal();
        String password = new String((char[]) token.getCredentials());

        // 连接HBase并验证用户名和密码
        try (Connection connection = hBaseConnectionFactory.createConnection();
             Table table = connection.getTable(TableName.valueOf("user_info"))) {
            Get get = new Get(Bytes.toBytes(username));
            Result result = table.get(get);
            if (result.isEmpty()) {
                throw new UnknownAccountException("用户不存在");
            }
            // 验证密码
            // ...
        } catch (IOException e) {
            throw new AuthenticationException("认证失败", e);
        }

        return new SimpleAuthenticationInfo(username, password, getName());
    }

    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        // 获取用户角色和权限
        String username = (String) principals.getPrimaryPrincipal();
        try (Connection connection = hBaseConnectionFactory.createConnection();
             Table table = connection.getTable(TableName.valueOf("user_roles"))) {
            Get get = new Get(Bytes.toBytes(username));
            Result result = table.get(get);
            if (result.isEmpty()) {
                return new SimpleAuthorizationInfo();
            }
            // 解析角色和权限
            // ...
        } catch (IOException e) {
            throw new AuthorizationException("授权失败", e);
        }

        SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
        // 添加角色和权限
        // ...
        return authorizationInfo;
    }
}

4. 配置HBase连接

创建一个配置类，例如HBaseConnectionFactory.java，并配置HBase的连接信息。

@Configuration
public class HBaseConnectionFactory {

    @Value("${hbase.zookeeper.quorum}")
    private String zookeeperQuorum;

    @Value("${hbase.zookeeper.port}")
    private int zookeeperPort;

    @Bean
    public ConnectionFactory connectionFactory() {
        Configuration config = HBaseConfiguration.create();
        config.set("hbase.zookeeper.quorum", zookeeperQuorum);
        config.set("hbase.zookeeper.port", zookeeperPort);
        return new HConnectionFactory(config);
    }
}

5. 配置Spring Security

创建一个配置类，例如SecurityConfig.java，并配置Spring Security以使用Shiro。

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private ShiroFilterFactoryBean shiroFilterFactoryBean;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/hbase/**").authenticated()
                .anyRequest().permitAll()
                .and()
                .formLogin()
                .loginPage("/login")
                .permitAll()
                .and()
                .logout()
                .permitAll();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(shiroFilterFactoryBean.getAuthcRealm());
    }
}

现在，你已经成功地在Spring集成HBase中配置了Shiro进行权限管理。用户可以通过/login页面登录，并根据配置的角色和权限访问相应的资源。
