redis 多表链接解决方案

直接上代码

配置文件就不上了自己百度一下

记得更换自己的序列化方式，看清楚1.x 的版本一般用的是 jdk 的

JdkSerializationRedisSerializer 序列化方式，我这是虽然是2.x的 但是兼容老项目 所以也采用的jdk

一般来说2.x的redis 用的是jackson2JsonRedisSerializer 序列化方式 我把代码也贴一下

Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
ObjectMapper om = new ObjectMapper();
om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
jackson2JsonRedisSerializer.setObjectMapper(om);

下面是正题 ， redis 配置多链接的代码，因为在单链接中切换库在并发中会出现问题，所以还是配置多个RedisTemplate 各管各的

@Value("${spring.redis.host}")
    private String redisHost;

    @Value("${spring.redis.port}")
    private int redisPort;

    @Value("${spring.redis.password}")
    private String redisAuth;

    @Value("${spring.redis.jedis.pool.max-active}")
    private int maxActive = 20;

    @Value("${spring.redis.jedis.pool.max-idle}")
    private int maxIdle = 10;

@Bean("redisTlbDb")
    public RedisTemplate<String,?> redisTlbDb() {
        return setRedisTemplate(0);
    }
    @Bean("redisUserDb")
    public RedisTemplate<String,?> redisUserDb() {
        return setRedisTemplate(1);
    }

    @Bean("redisMessageDb")
    public RedisTemplate<String,?> redisMessageDb() {
        return setRedisTemplate(15);
    }

public RedisTemplate<String, Object> setRedisTemplate(int  redisDb) {
        RedisTemplate<String, Object> template = new RedisTemplate<String, Object>();
        RedisConnectionFactory factory=connectionFactory(redisDb);
        template.setConnectionFactory(factory);
        template=setSerializer(template);
        return template;
    }

public RedisTemplate setSerializer(RedisTemplate<String, Object> template){
        JdkSerializationRedisSerializer jdkSerializationRedisSerializer = new JdkSerializationRedisSerializer();
        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
        template.setKeySerializer(stringRedisSerializer);
        template.setValueSerializer(jdkSerializationRedisSerializer);
        template.setHashKeySerializer(stringRedisSerializer);
        template.setHashValueSerializer(jdkSerializationRedisSerializer);
        template.afterPropertiesSet();
        return template;
    }

public RedisConnectionFactory connectionFactory(int redisDb) {
        JedisPoolConfig poolConfig = new JedisPoolConfig();
        poolConfig.setMaxTotal(maxActive);
        poolConfig.setMaxIdle(maxIdle);
        poolConfig.setTestOnBorrow(true);
        poolConfig.setTestOnReturn(false);
        poolConfig.setTestWhileIdle(true);
        JedisClientConfiguration jedisClientConfiguration = JedisClientConfiguration.builder().usePooling().poolConfig(poolConfig).and().build();
        RedisStandaloneConfiguration redisStandaloneConfiguration = new RedisStandaloneConfiguration();
        redisStandaloneConfiguration.setDatabase(redisDb);
        redisStandaloneConfiguration.setPort(redisPort);
        redisStandaloneConfiguration.setPassword(RedisPassword.of(redisAuth));
        redisStandaloneConfiguration.setHostName(redisHost);
        return new JedisConnectionFactory(redisStandaloneConfiguration, jedisClientConfiguration);
    }
