如何保护Spring Cloud Config Server

Question

我了解可以使用用户名和密码保护Spring Cloud Config Server,该用户名和密码必须由访问客户端提供.

如何防止客户端将这些用户名和密码以明文形式存储在客户端应用程序/服务的bootstrap.yml文件中？

Answer 1

非常基本的“基本身份验证”（来自这里https://github.com/spring-cloud-samples/configserver）

您可以通过包含对 Spring Security 的额外依赖来添加 HTTP Basic 身份验证（例如，通过 spring-boot-starter-security）。用户名为“user”，密码在启动时打印在控制台上（标准 Spring Boot 方法）。如果使用 maven ( pom.xml)：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>

如果你想要自定义用户/密码对，你需要在服务器配置文件中指明

security:
    basic:
        enabled: false

并在您的代码 ( BasicSecurityConfiguration.java) 中添加这个最小的类：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

@Configuration
//@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true)
public class BasicSecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Value("#{'${qa.admin.password:admin}'}") //property with default value
        String admin_password;

    @Value("#{'${qa.user.password:user}'}") //property with default value
            String user_password;

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth
            .inMemoryAuthentication()
            .withUser("user").password(user_password).roles("USER")
        .and()
            .withUser("admin").password(admin_password).roles("USER", "ACTUATOR");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .csrf()
            .disable()
            .httpBasic()
         .and()
            .authorizeRequests()
            .antMatchers("/encrypt/**").authenticated()
            .antMatchers("/decrypt/**").authenticated()
            //.antMatchers("/admin/**").hasAuthority("ROLE_ACTUATOR")
            //.antMatchers("/qa/**").permitAll()

        ;
    }

}

@Value("#{'${qa.admin.password:admin}'}") 允许在属性配置文件、环境变量或命令行中定义密码。

例如（application.yml）：

server:
  port: 8888

security:
    basic:
        enabled: false

qa:
  admin:
    password: adminadmin
  user:
    password: useruser

management:
  port: 8888
  context-path: /admin

logging:
  level:
    org.springframework.cloud: 'DEBUG'

spring:
  cloud:
    config:
      server:
        git:
          ignoreLocalSshSettings: true
          uri: ssh://git@gitlab.server.corp/repo/configuration.git

这对我有用。

编辑：您可以将基本用户配置直接放入application.yaml：

security:
  basic:
    enabled: true
    path: /**
  ignored: /health**,/info**,/metrics**,/trace**
  user:
    name: admin
    password: tupassword

对于 Spring Boot 2，application.yml 中的配置现在位于 spring.security.* ( https://docs.spring.io/spring-boot/docs/current/reference/html/appendix-application-properties.html#security - 属性）

spring.security:
  basic:
    enabled: true
    path: /**
  ignored: /health**,/info**,/metrics**,/trace**
  user:
    name: admin
    password: tupassword

Answer 2

适用于我的基本身份验证配置。

服务器端：

需要的依赖： org.springframework.boot:spring-boot-starter-security

引导程序.yml

server:
  port: 8888

spring:
  cloud:
    config:
      server:
        git:
          uri: git@bitbucket.org:someRepo/repoName.git
          hostKeyAlgorithm: ssh-rsa
          hostKey: "general hostKey for bitbucket.org"

  security:
    user:
      name: yourUser
      password: yourPassword

客户端：

引导程序.yml

spring:
  application:
    name: config
  profiles:
    active: dev
  cloud:
    config:
      uri: http://localhost:8888
      username: yourUser
      password: yourPassword

management:
  security:
    enabled: false

加密文本可以放置在 bootstrap.yml 中。
