SpringBoot2整合Redis多数据源步骤详解

redis是一个基于内存的高性能key-value数据库，具有极高的读写速度。本文介绍 SpringBoot 和 Redis 的整合，以及如何在项目中具体应用

配置文件属性

spring:
 redis:
  database: 1
  host: 192.168.50.144
  port: 6379
  password:
  timeout: 600 #Springboot2.0 不能设置为0
  lettuce:
   pool:
    max-active: 50
    max-wait: -1
    max-idle: 8
    min-idle: 0
 redis2:
  database: 2
  host: 192.168.50.144
  port: 6379
  password:
  timeout: 600

配置类

@EnableCaching
@Configuration
public class RedisDevConfiguration {
  @Bean(name = "redisDevTemplate")
  public StringRedisTemplate redisTemplate(@Value("${spring.redis.host}") String hostName,
                       @Value("${spring.redis.port}") int port, @Value("${spring.redis.password}") String password,
                       @Value("${spring.redis.lettuce.pool.max-idle}") int maxIdle, @Value("${spring.redis.lettuce.pool.max-active}") int maxTotal,
                       @Value("${spring.redis.database}") int index, @Value("${spring.redis.lettuce.pool.max-wait}") long maxWaitMillis,@Value("${spring.redis.lettuce.pool.min-idle}") int minIdle) {
    StringRedisTemplate temple = new StringRedisTemplate();
    temple.setConnectionFactory(
        connectionFactory(hostName, port, password, maxIdle, maxTotal, index, maxWaitMillis,minIdle));

    return temple;
  }


  @Bean(name = "redisUatTemplate")
  public StringRedisTemplate redisUatTemplate(@Value("${spring.redis2.host}") String hostName,
                       @Value("${spring.redis2.port}") int port, @Value("${spring.redis2.password}") String password,
                       @Value("${spring.redis.lettuce.pool.max-idle}") int maxIdle, @Value("${spring.redis.lettuce.pool.max-active}") int maxTotal,
                       @Value("${spring.redis2.database}") int index, @Value("${spring.redis.lettuce.pool.max-wait}") long maxWaitMillis,@Value("${spring.redis.lettuce.pool.min-idle}") int minIdle) {
    StringRedisTemplate temple = new StringRedisTemplate();
    temple.setConnectionFactory(
        connectionFactory(hostName, port, password, maxIdle, maxTotal, index, maxWaitMillis,minIdle));

    return temple;
  }
  public RedisConnectionFactory connectionFactory(String hostName, int port, String password, int maxIdle,
                          int maxTotal, int index, long maxWaitMillis,int minIdle) {
    JedisConnectionFactory jedis = new JedisConnectionFactory();
    jedis.setHostName(hostName);
    jedis.setPort(port);
    if (StringUtils.isNotEmpty(password)) {
      jedis.setPassword(password);
    }
    if (index != 0) {
      jedis.setDatabase(index);
    }
    jedis.setPoolConfig(poolCofig(maxIdle, maxTotal, maxWaitMillis,minIdle));
    // 初始化连接pool
    jedis.afterPropertiesSet();
    RedisConnectionFactory factory = jedis;

    return factory;
  }
  public JedisPoolConfig poolCofig(int maxIdle, int maxTotal, long maxWaitMillis,int minIdle) {
    JedisPoolConfig poolCofig = new JedisPoolConfig();
    poolCofig.setMaxIdle(maxIdle);
    poolCofig.setMaxTotal(maxTotal);
    poolCofig.setMaxWaitMillis(maxWaitMillis);
    poolCofig.setMinIdle(minIdle);
    return poolCofig;
  }
}

如何使用

	@Resource(name = "redisDevTemplate")
	private StringRedisTemplate template;
	@Resource(name = "redisUatTemplate")
	private StringRedisTemplate lockTemplate;
