JAVA SpringBoot中使用redis的事务

1、自定义redisConfig , 如果项目中要使用redis事务，最好将用事务和不用事务的redis分开。

@Configuration
public class RedisConfig {

    @Resource
    private RedisProperties redisProperties;


    @Bean("redisTemplate")
    public RedisTemplate redisTemplate() {
        RedisTemplate redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redis1ConnectionFactory());

        GenericJackson2JsonRedisSerializer genericJackson2JsonRedisSerializer = new GenericJackson2JsonRedisSerializer();
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(genericJackson2JsonRedisSerializer);
        redisTemplate.setHashKeySerializer(genericJackson2JsonRedisSerializer);
        redisTemplate.setHashValueSerializer(genericJackson2JsonRedisSerializer);
        redisTemplate.afterPropertiesSet();

        return redisTemplate;
    }

    @Bean("redisTransactionTemplate")
    public RedisTemplate redisTransactionTemplate() {
        RedisTemplate redisTransactionTemplate = new RedisTemplate<>();
        redisTransactionTemplate.setConnectionFactory(redis2ConnectionFactory());

        GenericJackson2JsonRedisSerializer genericJackson2JsonRedisSerializer = new GenericJackson2JsonRedisSerializer();
        redisTransactionTemplate.setKeySerializer(new StringRedisSerializer());
        redisTransactionTemplate.setValueSerializer(genericJackson2JsonRedisSerializer);
        redisTransactionTemplate.setHashKeySerializer(genericJackson2JsonRedisSerializer);
        redisTransactionTemplate.setHashValueSerializer(genericJackson2JsonRedisSerializer);
        redisTransactionTemplate.afterPropertiesSet();
        //开启事务
        redisTransactionTemplate.setEnableTransactionSupport(true);

        return redisTransactionTemplate;
    }

    @Bean
    @Primary
    public RedisConnectionFactory redis1ConnectionFactory() {
        RedisStandaloneConfiguration localhost = new RedisStandaloneConfiguration(redisProperties.getHost(), redisProperties.getPort());
        if(StrUtil.isNotEmpty(redisProperties.getPassword())){
            localhost.setPassword(redisProperties.getPassword());
        }
        if(Objects.nonNull(redisProperties.getDatabase())){
            localhost.setDatabase(redisProperties.getDatabase());
        }

        JedisClientConfiguration.JedisPoolingClientConfigurationBuilder jpb =
                (JedisClientConfiguration.JedisPoolingClientConfigurationBuilder) JedisClientConfiguration.builder();
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        jedisPoolConfig.setMaxIdle(redisProperties.getMaxIdle());
        jedisPoolConfig.setMinIdle(redisProperties.getMinIdle());
        jedisPoolConfig.setMaxTotal(redisProperties.getMaxActive());
        jedisPoolConfig.setMaxWaitMillis(redisProperties.getMaxWait());
        jedisPoolConfig.setEvictorShutdownTimeoutMillis(redisProperties.getTimeout());
        jpb.poolConfig(jedisPoolConfig);

        return new JedisConnectionFactory(localhost,jpb.build());
    }

    @Bean
    public RedisConnectionFactory redis2ConnectionFactory() {
        RedisStandaloneConfiguration localhost = new RedisStandaloneConfiguration(redisProperties.getHost(), redisProperties.getPort());
        if(StrUtil.isNotEmpty(redisProperties.getPassword())){
            localhost.setPassword(redisProperties.getPassword());
        }
        if(Objects.nonNull(redisProperties.getDatabase())){
            localhost.setDatabase(redisProperties.getDatabase());
        }

        JedisClientConfiguration.JedisPoolingClientConfigurationBuilder jpb =
                (JedisClientConfiguration.JedisPoolingClientConfigurationBuilder) JedisClientConfiguration.builder();
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        jedisPoolConfig.setMaxIdle(redisProperties.getMaxIdle());
        jedisPoolConfig.setMinIdle(redisProperties.getMinIdle());
        jedisPoolConfig.setMaxTotal(redisProperties.getMaxActive());
        jedisPoolConfig.setMaxWaitMillis(redisProperties.getMaxWait());
        jedisPoolConfig.setEvictorShutdownTimeoutMillis(redisProperties.getTimeout());
        jpb.poolConfig(jedisPoolConfig);

        return new JedisConnectionFactory(localhost,jpb.build());
    }

}

@Order(value = 1)
@Data
@Component
public class RedisProperties {

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

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

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

    @Value("${spring.redis.database}")
    private Integer database;

    @Value("${spring.redis.timeout}")
    private Integer timeout;

    @Value("${spring.redis.lettuce.pool.max-idle}")
    public Integer maxIdle;

    @Value("${spring.redis.lettuce.pool.min-idle}")
    public Integer minIdle;

    @Value("${spring.redis.lettuce.pool.max-active}")
    public Integer maxActive;

    @Value("${spring.redis.lettuce.pool.max-wait}")
    public Integer maxWait;



}

需要事务的注入 

@Resource(name = "redisTransactionTemplate")

不需要事务的注入

@Resource(name = "redisTemplate")

事务完整执行流程

redisTransactionTemplate.multi();   //开启

redisTransactionTemplate.exec();  //执行

redisTransactionTemplate.discard();  //取消
