SpringBoot 集成Jedis操作Redis缓存

  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 = 127.0.0.1spring.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 = 6379spring.redis.pool.maxIdle = 20spring.redis.pool.maxTotal = 500spring.redis.pool.numTestsPerEvictionRun = 3spring.redis.pool.testOnBorrow = truespring.redis.pool.blockWhenExhausted = falsespring.redis.pool.testOnReturn = false

然后配置JedisConfig配置类，注入配置文件中的值：

package com.cictec.cloud.bus.minddleware.gps.common.jedis;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。

package com.cictec.cloud.bus.minddleware.gps.common.jedis;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;@Configurationpublic class JedisConfiguration {@AutowiredJedisConfig 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：
