首先是redis各个参数的配置，在 application-dev.properties中配置如下：

#redis配置
redis.server.host=192.168.50.162
redis.server.port=6379
redis.server.password=password
redis.server.timeOut=5000
redis.server.maxIdle=50
redis.server.maxWaitMillis=5000
redis.server.maxTotal=500

对 redis 配置参数进行读取和绑定，配置属性注入到 JedisProperties

import org.springframework.boot.context.properties.ConfigurationProperties;

@ConfigurationProperties(prefix = JedisProperties.JEDIS_PREFIX)
public class JedisProperties {

    public static final String JEDIS_PREFIX = "redis.server";

    private String host;

    private int port;

    private String password;

    private int maxTotal;

    private int maxIdle;

    private int maxWaitMillis;

    private int timeOut;

    public int getTimeOut() {
        return timeOut;
    }

    public void setTimeOut(int timeOut) {
        this.timeOut = timeOut;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    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 int getMaxTotal() {
        return maxTotal;
    }

    public void setMaxTotal(int maxTotal) {
        this.maxTotal = maxTotal;
    }

    public int getMaxIdle() {
        return maxIdle;
    }

    public void setMaxIdle(int maxIdle) {
        this.maxIdle = maxIdle;
    }

    public int getMaxWaitMillis() {
        return maxWaitMillis;
    }

    public void setMaxWaitMillis(int maxWaitMillis) {
        this.maxWaitMillis = maxWaitMillis;
    }

}

配置了 Redis 连接池之后，将 Redis 连接池 注入到 RedisClient 中，并生成 RedisClient Bean

import com.mljr.auth.config.properties.JedisProperties;
import com.mljr.auth.util.RedisClient;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.JedisPoolConfig;

@Configuration
@EnableConfigurationProperties(JedisProperties.class)
@ConditionalOnClass(RedisClient.class)
public class JedisConfig {

    private Logger logger = LoggerFactory.getLogger(JedisConfig.class);

    @Autowired
    private JedisProperties prop;

    @Bean(name = "jedisPool")
    public JedisPool jedisPool() {
        JedisPoolConfig config = new JedisPoolConfig();
        config.setMaxTotal(prop.getMaxTotal());
        config.setMaxIdle(prop.getMaxIdle());
        config.setMaxWaitMillis(prop.getMaxWaitMillis());
        return new JedisPool(config, prop.getHost(), prop.getPort(), prop.getTimeOut(), prop.getPassword());
    }

    @Bean
    @ConditionalOnMissingBean(RedisClient.class)
    public RedisClient redisClient(@Qualifier("jedisPool") JedisPool pool) {
        logger.info("初始化……Redis Client==Host={},Port={}", prop.getHost(), prop.getPort());
        RedisClient redisClient = new RedisClient();
        redisClient.setJedisPool(pool);
        return redisClient;
    }

}

配置一些常用的 redis 的操作：

import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;

public class RedisClient {

    private JedisPool jedisPool;

    public void set(String key, Object value) {
        Jedis jedis = null;
        try {
            jedis = jedisPool.getResource();
            jedis.set(key, value.toString());
        }catch (Exception e){
            e.printStackTrace();
        }finally {
            jedis.close();
        }
    }

    /**
     * 设置过期时间 
     * @param key
     * @param value
     * @param exptime
     * @throws Exception
     */
    public void setWithExpireTime(String key, String value, int exptime) {
        Jedis jedis = null;
        try {
            jedis = jedisPool.getResource();
            jedis.set(key, value, "NX", "EX", 300);
        } catch (Exception e){
            e.printStackTrace();
        }finally {
            jedis.close();
        }
    }

    public String get(String key) {

        Jedis jedis = null;
        try {
            jedis = jedisPool.getResource();
            return jedis.get(key);
        } catch (Exception e){
            e.printStackTrace();
        }finally {
            if (jedis != null)
            jedis.close();
        }
        return null;
    }
    public JedisPool getJedisPool() {
        return jedisPool;
    }

    public void setJedisPool(JedisPool jedisPool) {
        this.jedisPool = jedisPool;
    }

}

大功告成，使用注解的方式引入就可以使用了

@Autowired
    private RedisClient redisClient;
    ....
    ....
    ....
