无法连接到启用了 SSL 的 GCP 中的 Redis

Question

我正在使用 Spring-boot-starter-redis 依赖关系连接到 Redis（下面是我从 gradle 依赖关系

中摘录的片段

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.springframework.boot:spring-boot-starter-actuator'
    implementation 'org.springframework.boot:spring-boot-starter-data-redis'
    compileOnly 'org.projectlombok:lombok:1.18.20'
    annotationProcessor 'org.projectlombok:lombok:1.18.20'
}

我现在要迁移到 GCP，GCP 中的 redis 启用了 SSL，因此，我以这种方式配置了我的 spring 属性

spring.redis.ssl=true
spring.redis.host=xxxxxx
spring.redis.port=6378

当我禁用 ssl 时，它工作得很好。但是当我启用它时，我得到以下错误..有没有办法在 Spring 配置中注入 PEM 证书？

请帮忙

Answer 1

我是这样解决的

spring-boot-starter-data-redis 依赖默认使用 Lettuce
要通过 ssl 连接到 Redis spring.redis.ssl=true 属性需要启用。
如果证书的 CA 是唯一的并且不是 Java 的 JKS 的一部分，那么您有两个选择，将密钥导入 JKS 或禁用 [=13=]

引用Google Docs here

中给出的内容

For example, Lettuce is a popular Java client for Redis. Their documentation provides an example for connecting natively with TLS (see Example 47). Given that the Java Security Manager does not allow self-signed certificates by default, an additional option needs to be specified in the Redis URI construction .withVerifyPeer(false)

我禁用了 SSL Verification。连接仍将通过 SSL 进行，但仅验证我通过配置一个 bean 禁用了它。

我也不担心 man-in-the-middle-attack，因为我的 Redis 只暴露给我的 GKE 集群。所以这个解决方案对我来说很好

@Configuration
public class RedisSSLConfiguration {

    @Bean
    @ConditionalOnProperty("spring.redis.ssl")
    public LettuceClientConfigurationBuilderCustomizer builderCustomizer() {
        return builder -> builder.useSsl().disablePeerVerification();
    }
}

无法连接到启用了 SSL 的 GCP 中的 Redis
