SpringBoot2.1.9 多Redis Jedis配置

 一、配置文件

pom.xml

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<dependency>
	<groupId>redis.clients</groupId>
	<artifactId>jedis</artifactId>
	<!--注意：只有2.x版本才支持，3.x版本不兼容报错NoClassDefFoundError:redis/clients/util/SafeEncoder -->
	<version>2.9.3</version>
</dependency>

application.xml 

spring:
  application:
    name: double-redis-jedis
  profiles:
    active: dev
 
  jackson:
    date-format: yyyy-MM-dd HH:mm:ss
    time-zone: GMT+8
 
  server:
    port: 8008
 
sys:
  redis:
    one:    
      host: 192.168.1.2
      port: 5009
      timeout: 6000
      jedis:
         pool:
           max-active: 30
           max-idle: 10
           max-wait: 6000
      slave:

               - sentinel-group002.mk.com:10003
               - sentinel-group003.mk.com:10003

二、配置Configuration Bean

Jedis配置基类

public abstract class AbstractJedisRedisConfig {

    public JedisConnectionFactory createJedisConnectionFactory(RedisProperties properties) {
        JedisClientConfiguration clientConfiguration = getJedisClientConfiguration(properties);
        RedisSentinelConfiguration sentinelConf = getSentinelConfig(properties);
        if (sentinelConf != null) {
            return new JedisConnectionFactory(sentinelConf, clientConfiguration);
        }

        RedisClusterConfiguration clusterConf = getClusterConfiguration(properties);
        if (clusterConf != null) {
            return new JedisConnectionFactory(clusterConf, clientConfiguration);
        }
        return new JedisConnectionFactory(getStandaloneConfig(properties), clientConfiguration);
    }

    private JedisClientConfiguration getJedisClientConfiguration(RedisProperties properties) {
        JedisClientConfiguration.JedisClientConfigurationBuilder builder = applyProperties(JedisClientConfiguration.builder(), properties);
        RedisProperties.Pool pool = properties.getJedis().getPool();
        if (pool != null) {
            applyPooling(pool, builder);
        }
        if (StringUtils.hasText(properties.getUrl())) {
            customizeConfigurationFromUrl(builder, properties);
        }

        return builder.build();
    }

    private JedisClientConfiguration.JedisClientConfigurationBuilder applyProperties(JedisClientConfiguration.JedisClientConfigurationBuilder builder,
                                                                                     RedisProperties properties) {
        if (properties.isSsl()) {
            builder.useSsl();
        }
        if (properties.getTimeout() != null) {
            Duration timeout = properties.getTimeout();
            builder.readTimeout(timeout).connectTimeout(timeout);
        }
        return builder;
    }

    private void applyPooling(RedisProperties.Pool pool,
                              JedisClientConfiguration.JedisClientConfigurationBuilder builder) {
        builder.usePooling().poolConfig(jedisPoolConfig(pool));
    }

    private JedisPoolConfig jedisPoolConfig(RedisProperties.Pool pool) {
        JedisPoolConfig config = new JedisPoolConfig();
        config.setMaxTotal(pool.getMaxActive());
        config.setMaxIdle(pool.getMaxIdle());
        config.setMinIdle(pool.getMinIdle());
        if (pool.getTimeBetweenEvictionRuns() != null) {
            config.setTimeBetweenEvictionRunsMillis(pool.getTimeBetweenEvictionRuns().toMillis());
        }
        if (pool.getMaxWait() != null) {
            config.setMaxWaitMillis(pool.getMaxWait().toMillis());
        }
        return config;
    }

    private void customizeConfigurationFromUrl(JedisClientConfiguration.JedisClientConfigurationBuilder builder, RedisProperties properties) {
        ConnectionInfo connectionInfo = parseUrl(properties.getUrl());
        if (connectionInfo.isUseSsl()) {
            builder.useSsl();
        }
    }


    private RedisSentinelConfiguration getSentinelConfig(RedisProperties properties) {

        RedisProperties.Sentinel sentinelProperties = properties.getSentinel();
        if (sentinelProperties != null) {
            RedisSentinelConfiguration config = new RedisSentinelConfiguration();
            config.master(sentinelProperties.getMaster());
            config.setSentinels(createSentinels(sentinelProperties));
            if (properties.getPassword() != null) {
                config.setPassword(RedisPassword.of(properties.getPassword()));
            }
            config.setDatabase(properties.getDatabase());
            return config;
        }
        return null;
    }

    private List<RedisNode> createSentinels(RedisProperties.Sentinel sentinel) {
        List<RedisNode> nodes = new ArrayList<>();
        for (String node : sentinel.getNodes()) {
            try {
                String[] parts = StringUtils.split(node, ":");
                Assert.state(parts.length == 2, "Must be defined as 'host:port'");
                nodes.add(new RedisNode(parts[0], Integer.valueOf(parts[1])));
            }
            catch (RuntimeException ex) {
                throw new IllegalStateException("Invalid redis sentinel " + "property '" + node + "'", ex);
            }
        }
        return nodes;
    }

    private RedisClusterConfiguration getClusterConfiguration(RedisProperties properties) {

        if (properties.getCluster() == null) {
            return null;
        }
        RedisProperties.Cluster clusterProperties = properties.getCluster();
        RedisClusterConfiguration config = new RedisClusterConfiguration(clusterProperties.getNodes());
        if (clusterProperties.getMaxRedirects() != null) {
            config.setMaxRedirects(clusterProperties.getMaxRedirects());
        }
        if (properties.getPassword() != null) {
            config.setPassword(RedisPassword.of(properties.getPassword()));
        }
        return config;
    }

    private RedisStandaloneConfiguration getStandaloneConfig(RedisProperties properties) {
        RedisStandaloneConfiguration config = new RedisStandaloneConfiguration();
        if (StringUtils.hasText(properties.getUrl())) {
            ConnectionInfo connectionInfo = parseUrl(properties.getUrl());
            config.setHostName(connectionInfo.getHostName());
            config.setPort(connectionInfo.getPort());
            config.setPassword(RedisPassword.of(connectionInfo.getPassword()));
        }
        else {
            config.setHostName(properties.getHost());
            config.setPort(properties.getPort());
            config.setPassword(RedisPassword.of(properties.getPassword()));
        }
        config.setDatabase(properties.getDatabase());
        return config;
    }

   private ConnectionInfo parseUrl(String url) {
        try {
            URI uri = new URI(url);
            boolean useSsl = (url.startsWith("rediss://"));
            String password = null;
            if (uri.getUserInfo() != null) {
                password = uri.getUserInfo();
                int index = password.indexOf(':');
                if (index >= 0) {
                    password = password.substring(index + 1);
                }
            }
            return new ConnectionInfo(uri, useSsl, password);
        }
        catch (URISyntaxException ex) {
            throw new IllegalArgumentException("Malformed url '" + url + "'", ex);
        }
    }

    private static class ConnectionInfo {

        private final URI uri;

        private final boolean useSsl;

        private final String password;

        public ConnectionInfo(URI uri, boolean useSsl, String password) {
            this.uri = uri;
            this.useSsl = useSsl;
            this.password = password;
        }

        public boolean isUseSsl() {
            return this.useSsl;
        }

        public String getHostName() {
            return this.uri.getHost();
        }

        public int getPort() {
            return this.uri.getPort();
        }

        public String getPassword() {
            return this.password;
        }

    }
}

（1）第一个Redis配置

public class OneJedisRedisConfig  extends AbstractJedisRedisConfig{

    @Bean
    public StringRedisTemplate oneStringRedisTemplate(@Autowired @Qualifier("oneRedisConnectionFactory")
                                                              RedisConnectionFactory redisConnectionFactory){

        StringRedisTemplate template = new StringRedisTemplate();
        template.setConnectionFactory(redisConnectionFactory);
        return template;

    }

    @Bean
    public JedisConnectionFactory oneRedisConnectionFactory(@Autowired @Qualifier("oneRedisProperties") RedisProperties properties){
        return createJedisConnectionFactory(properties);
    }


    @Bean
    @ConfigurationProperties("sys.redis.one")
    public RedisProperties oneRedisProperties() {
        return new RedisProperties();
    }
}

（2）第二个Redis配置(主)

public class TwoJedisRedisConfig extends AbstractJedisRedisConfig{

    @Primary
    @Bean
    public StringRedisTemplate twoStringRedisTemplate(@Autowired @Qualifier("twoRedisConnectionFactory")
                                                              RedisConnectionFactory redisConnectionFactory) {

        StringRedisTemplate template = new StringRedisTemplate();
        template.setConnectionFactory(redisConnectionFactory);
        return template;

    }

    @Primary
    @Bean
    public JedisConnectionFactory twoRedisConnectionFactory(@Autowired @Qualifier("twoRedisProperties") RedisProperties properties){
        return createJedisConnectionFactory(properties);
    }


    @Primary
    @Bean
    @ConfigurationProperties("sys.redis.two")
    public RedisProperties twoRedisProperties() {
        return new RedisProperties();
    }
}

（3）redis导入配置

@Configuration
@Import({OneRedisConfig.class, TwoRedisConfig.class})
public class RedisConfig {

}
