在使用SpringBoot构建SpringCloud微服务时，需要用到Redis做数据缓存，提高业务逻辑的处理。所以就不得不让SpringBoot集成Redis，但如果使用官方的Redis去操作的话，你叫麻烦，所以就使用Jedis去操作Reids，这样操作简便，编码效率打打提高。这篇就介绍SpringBoot如何集成Jedis去操作Redis。
首先在application.properties文件中加入redis的基本配置：
#多redis连接配置 spring.redis.shard.1.host = 127.0.0.1 spring.redis.shard.1.password = spring.redis.shard.1.port = 6379 #spring.redis.shard.2.host = 127.0.0.1 #spring.redis.shard.2.password = #spring.redis.shard.2.port = 6379 spring.redis.pool.maxIdle = 20 spring.redis.pool.maxTotal = 500 spring.redis.pool.numTestsPerEvictionRun = 3 spring.redis.pool.testOnBorrow = true spring.redis.pool.blockWhenExhausted = false spring.redis.pool.testOnReturn = false 然后配置JedisConfig配置类，注入配置文件中的值： import java.io.Serializable; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.stereotype.Component; @Component @ConfigurationProperties(prefix = "spring.redis.pool") public class JedisConfig implements Serializable{ /** * */ private static final long serialVersionUID = 1L; private String host; private int port; private String password; private Integer maxTotal; private Integer maxIdle; private Integer minIdle; private Long maxWaitMillis; private boolean testOnBorrow; private boolean testOnReturn; private boolean testWhileIdle; public String getHost() { return host; } public void setHost(String host) { this.host = host; } public int getPort() { return port; } public void setPort(int port) { this.port = port; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public Integer getMaxTotal() { return maxTotal; } public void setMaxTotal(Integer maxTotal) { this.maxTotal = maxTotal; } public Integer getMaxIdle() { return maxIdle; } public void setMaxIdle(Integer maxIdle) { this.maxIdle = maxIdle; } public Integer getMinIdle() { return minIdle; } public void setMinIdle(Integer minIdle) { this.minIdle = minIdle; } public Long getMaxWaitMillis() { return maxWaitMillis; } public void setMaxWaitMillis(Long maxWaitMillis) { this.maxWaitMillis = maxWaitMillis; } public boolean isTestOnBorrow() { return testOnBorrow; } public void setTestOnBorrow(boolean testOnBorrow) { this.testOnBorrow = testOnBorrow; } public boolean isTestOnReturn() { return testOnReturn; } public void setTestOnReturn(boolean testOnReturn) { this.testOnReturn = testOnReturn; } public boolean isTestWhileIdle() { return testWhileIdle; } public void setTestWhileIdle(boolean testWhileIdle) { this.testWhileIdle = testWhileIdle; } } 最后配置JedisConfiguration类，生成2个工具Bean，redisTemplate和forecastRedisTemplate，在需要使用jedis的地方注入bean，可以对redis进行操作。 import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.data.redis.connection.jedis.JedisConnectionFactory; import org.springframework.data.redis.core.StringRedisTemplate; import redis.clients.jedis.JedisPoolConfig; @Configuration public class JedisConfiguration { @Autowired JedisConfig redisConfig; public JedisConnectionFactory convertJedisConnectionFactory() { JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory(); jedisConnectionFactory.setHostName(redisConfig.getHost()); jedisConnectionFactory.setPort(redisConfig.getPort()); jedisConnectionFactory.setPassword(redisConfig.getPassword()); JedisPoolConfig jedisPoolConfig = new JedisPoolConfig(); jedisPoolConfig.setMaxTotal(redisConfig.getMaxTotal()); jedisPoolConfig.setMaxIdle(redisConfig.getMaxIdle()); jedisPoolConfig.setMinIdle(redisConfig.getMinIdle()); jedisPoolConfig.setMaxWaitMillis(redisConfig.getMaxWaitMillis()); jedisPoolConfig.setTestOnBorrow(redisConfig.isTestOnBorrow()); jedisPoolConfig.setTestOnReturn(redisConfig.isTestOnReturn()); jedisPoolConfig.setTestWhileIdle(redisConfig.isTestWhileIdle()); jedisConnectionFactory.setPoolConfig(jedisPoolConfig); return jedisConnectionFactory; } @Bean(name = "redisTemplate") public StringRedisTemplate convertStringRedisTemplate() { StringRedisTemplate stringRedisTemplate = new StringRedisTemplate(convertJedisConnectionFactory()); return stringRedisTemplate; } @Bean(name = "forecastRedisTemplate") public StringRedisTemplate convertStringRedisTemplate1() { StringRedisTemplate stringRedisTemplate = new StringRedisTemplate(convertJedisConnectionFactory()); return stringRedisTemplate; } }
使用的地方可以注入bean（redisTemplate，forecastRedisTemplate），名字在JedisConfiguration类的bean（“name”）中自行更改。如图所示：
