Spring Redis 启用TLS配置支持(踩坑&解决)

由于线上Redis要启用TLS,搜遍了google百度也没一个标准的解决方案,要不这个方法没有,要不那个类找不到...要不就是配置了还是一直连不上redis....

本文基于 spring-data-redis-2.1.9.RELEASE 版本来提供一个解决方案:

1.运维那边提供过来三个文件,分别是redis.crt redis.key ca.crt

 redis.crt 是公钥 redis.key是私钥 ca.crt是服务器证书,由于是测试生成的所以我代码中直接不校验,该文件对我无效

2. 使用命令 

openssl pkcs12 -export -in redis.crt -inkey redis.key -out redis_keystore.p12

生成PKCS#12证书束.(如果你们用的是JDK8_301以上版本则可以直接使用该文件)

3.使用命令 

keytool -importkeystore -srckeystore redis_keystore.p12 -srcstoretype PKCS12 -deststoretype JKS -destkeys
tore redis_keystore.jks

生成jks Java密钥库 (如果你们用的是JDK8_301以下版本则需要使用这种格式)

4.yml配置

spring:
  redis:
    database: 0
    host: 192.168.3.231
    password:
    port: 6380
    ssl:
      enable: true
      keystore:
        file: classpath:redis_keystore.jks
        password: yourpassword

5. 将2/3步骤生成的文件放在resources目录下

6. RedisConfig代码配置

@Configuration
@RequiredArgsConstructor
public class RedisConfig {


    @Value("${spring.redis.host}")
    private String host;
    @Value("${spring.redis.port}")
    private Integer port;
    @Value("${spring.redis.password:}")
    private String password;
    @Value("${spring.redis.ssl.enable:}")
    private Boolean ssl;
    @Value("${spring.redis.ssl.keystore.file:}")
    private Resource keystore;
    @Value("${spring.redis.ssl.keystore.password:}")
    private String keystorePassword;

    private final ResourceLoader resourceLoader;

    @Bean
    public LettuceConnectionFactory lettuceConnectionFactory() throws Exception {
        RedisStandaloneConfiguration redisStandaloneConfiguration = new RedisStandaloneConfiguration();
        redisStandaloneConfiguration.setHostName(host);
        redisStandaloneConfiguration.setPort(port);
        redisStandaloneConfiguration.setPassword(password);
        LettuceClientConfiguration.LettuceClientConfigurationBuilder lettuceClientConfigurationBuilder =
                LettuceClientConfiguration.builder();
        if (ssl != null && ssl) {
            //此处解决springboot打包后取不到资源文件问题
            String tempPath = System.getProperty("java.io.tmpdir") + File.separator + "bms_" + System.currentTimeMillis();
            String tempFile = tempPath + File.separator + keystore.getFilename();
            File path = new File(tempPath);
            if (!path.exists()) {
                path.mkdir();
            }
            File keystoreFile = new File(tempFile);
            FileUtils.copyInputStreamToFile(keystore.getInputStream(), keystoreFile);
            //此处配置SSL keystore
            SslOptions sslOptions = SslOptions.builder().jdkSslProvider()
                    .keystore(keystoreFile, keystorePassword.toCharArray())
                    .build();
            ClientOptions clientOptions = ClientOptions
                    .builder()
                    .sslOptions(sslOptions)
                    .build();
            //disablePeerVerification 关闭证书校验
            lettuceClientConfigurationBuilder
                    .clientOptions(clientOptions)
                    .useSsl().disablePeerVerification();
        }
        LettuceClientConfiguration lettuceClientConfiguration = lettuceClientConfigurationBuilder.build();
        return new LettuceConnectionFactory(redisStandaloneConfiguration, lettuceClientConfiguration);
    }
}

7.编写test进行测试

 @Test
    public void test() {
        redisTemplate.opsForValue().set("TEST", "111");
    }

至此,整个TLS配置就完成了.

由于没有比较完善的方案,整整浪费了我一天多的时间. 

记录一下,希望能帮到更多的人!
