redis是一個(gè)基于內(nèi)存的高性能key-value數(shù)據(jù)庫(kù)，具有極高的讀寫速度。本文介紹 SpringBoot 和 Redis 的整合，以及如何在項(xiàng)目中具體應(yīng)用

配置文件屬性

spring: redis: database: 1 host: 192.168.50.144 port: 6379 password: timeout: 600 #Springboot2.0 不能設(shè)置為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

配置類

@EnableCaching@Configurationpublic 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)); // 初始化連接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;

以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持好吧啦網(wǎng)。
