在Spring Boot中使用Apache ZooKeeper进行安全管理，可以通过以下步骤来实现：

1. 配置ZooKeeper安全认证：

   • 在ZooKeeper的配置文件（通常是zoo.cfg）中，确保开启了安全认证功能。例如：

     authProvider=org.apache.zookeeper.server.auth.DigestAuthenticationProvider
     auth.digest.user1=password1, digest
     auth.digest.user2=password2, digest
     

   • 创建用户并分配权限。可以使用ZooKeeper自带的工具zkpasswd来创建用户和密码哈希：

     zkpasswd -create user1 password1
     zkpasswd -create user2 password2
     

2. 配置Spring Boot应用以使用ZooKeeper安全认证：

   • 在Spring Boot应用的application.yml或application.properties文件中，配置ZooKeeper连接字符串和安全认证信息：

     spring:
       zookeeper:
         connect: 127.0.0.1:2181
         username: user1
         password: password1
     

   • 使用Spring Security集成ZooKeeper安全认证。创建一个配置类来启用ZooKeeper的安全认证：

     import org.apache.zookeeper.client.ZooKeeper;
     import org.springframework.beans.factory.annotation.Value;
     import org.springframework.context.annotation.Bean;
     import org.springframework.context.annotation.Configuration;
     import org.springframework.security.config.annotation.web.builders.HttpSecurity;
     import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
     import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
     import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
     import org.springframework.security.crypto.password.PasswordEncoder;
     
     @Configuration
     @EnableWebSecurity
     public class ZooKeeperSecurityConfig extends WebSecurityConfigurerAdapter {
     
         @Value("${spring.zookeeper.username}")
         private String username;
     
         @Value("${spring.zookeeper.password}")
         private String password;
     
         @Bean
         public PasswordEncoder passwordEncoder() {
             return new BCryptPasswordEncoder();
         }
     
         @Override
         protected void configure(HttpSecurity http) throws Exception {
             http
                 .authorizeRequests()
                     .anyRequest().authenticated()
                     .and()
                 .formLogin()
                     .loginPage("/login")
                     .permitAll()
                     .and()
                 .logout()
                     .permitAll();
         }
     
         @Bean
         public ZooKeeper zooKeeper(PasswordEncoder passwordEncoder) throws Exception {
             String passwordHash = passwordEncoder.encode(password);
             return new ZooKeeper("127.0.0.1:2181", 3000, event -> {
                 // 处理连接事件
             }, username, passwordHash);
         }
     }
     

3. 创建登录页面和控制器：

   • 创建一个简单的登录页面（例如login.html）和相应的控制器来处理登录请求：

     
     
     
         
     
     
         
     Login
         
     
             Username:
             
     
             Password:
             
     
             Login
         
     
     
     

     import org.springframework.stereotype.Controller;
     import org.springframework.web.bind.annotation.GetMapping;
     import org.springframework.web.bind.annotation.PostMapping;
     
     @Controller
     public class LoginController {
     
         @GetMapping("/login")
         public String login() {
             return "login";
         }
     
         @PostMapping("/login")
         public String loginSubmit(String username, String password) {
             // 这里可以添加实际的登录验证逻辑
             return "redirect:/home";
         }
     }
     

4. 保护ZooKeeper节点：

   • 使用ZooKeeper的安全特性来保护节点。例如，可以使用zkcli工具来设置节点的ACL（访问控制列表）：

     echo -e "auth digest user1=password1,digest\ncreate /protectedNode myData \"Protected data\"" | nc localhost 2181
     

   • 在Spring Boot应用中，可以使用ZooKeeper的Java API来创建和管理ACL：

     import org.apache.zookeeper.*;
     import org.apache.zookeeper.data.ACL;
     import org.apache.zookeeper.data.Stat;
     import org.springframework.beans.factory.annotation.Autowired;
     import org.springframework.stereotype.Service;
     
     import java.util.Collections;
     import java.util.List;
     
     @Service
     public class ZooKeeperService {
     
         @Autowired
         private ZooKeeper zooKeeper;
     
         public void createProtectedNode(String path, String data) throws KeeperException, InterruptedException {
             ACL acl = new ACL(ACL.PermSet.ALL, Collections.singletonList(new ACL.User("user1", ACL.ID.ANYONE)));
             Stat stat = zooKeeper.exists(path, false);
             if (stat == null) {
                 zooKeeper.create(path, data.getBytes(), acl, CreateMode.PERSISTENT);
             } else {
                 zooKeeper.setData(path, data.getBytes(), stat.getVersion());
             }
         }
     }
     

通过以上步骤，你可以在Spring Boot应用中使用ZooKeeper进行安全管理，确保只有经过认证的用户才能访问受保护的资源。
