SpringBoot配置Redis连接池

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=192.168.50.162redis.server.port=6379redis.server.password=passwordredis.server.timeOut=5000redis.server.maxIdle=50redis.server.maxWaitMillis=5000redis.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;    ....    ....    ....
