zookeeper springboot如何进行安全管理

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：

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
```

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);
    }
}

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：

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
    <title>Login</title>
</head>
<body>
    <h1>Login</h1>
    <form method="post" action="/login">
        <label for="username">Username:</label>
        <input type="text" id="username" name="username" required><br>
        <label for="password">Password:</label>
        <input type="password" id="password" name="password" required><br>
        <button type="submit">Login</button>
    </form>
</body>
</html>

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";
    }
}

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。
