本次和大家分享的是在springboot集成使用redis，这里使用的是redis的jedis客户端，如下添加依赖

<dependency><groupId>redis.clients</groupId><artifactId>jedis</artifactId>
</dependency>

然后需要redis的相关配置（这里我的redis密码是空）

spring:redis:single: 192.168.146.28:6378jedis:pool:max-idle: 8max-active: 8max-wait: 3000timeout: 3000password:

这是redis的一般配置，具体调优可以设置这些参数，下面在JedisConfig类中读取这些设置

    @Value("${spring.redis.single}")private String strSingleNode;@Value("${spring.redis.jedis.pool.max-idle}")private Integer maxIdle;@Value("${spring.redis.jedis.pool.max-active}")private Integer maxActive;@Value("${spring.redis.jedis.pool.max-wait}")private Integer maxAWait;@Value("${spring.redis.timeout}")private Integer timeout;@Value("${spring.redis.password}")private String password;

有上面的配置，就需要有代码里面设置下，这里创建一个返回JedisPoolConfig的方法

    /*** jedis配置** @return*/public JedisPoolConfig getJedisPoolConfig() {JedisPoolConfig config = new JedisPoolConfig();config.setMaxIdle(maxIdle); #最大空闲数config.setMaxWaitMillis(maxAWait); #最大等待时间config.setMaxTotal(maxActive); #最大连接数return config;}

有了配置，接下来就创建JedisPool，这里把JedisPool托管到spring中

     /*** 获取jedispool** @return*/@Beanpublic JedisPool getJedisPool() {JedisPoolConfig config = getJedisPoolConfig();System.out.println("strSingleNode:" + this.strSingleNode);String[] nodeArr = this.strSingleNode.split(":");JedisPool jedisPool = null;if (this.password.isEmpty()) {jedisPool = new JedisPool(config,nodeArr[0],Integer.valueOf(nodeArr[1]),this.timeout);} else {jedisPool = new JedisPool(config,nodeArr[0],Integer.valueOf(nodeArr[1]),this.timeout,this.password);}return jedisPool;}

上面简单区分了无密码的情况，到此jedis的配置和连接池就基本搭建完了，下面就是封装使用的方法，这里以set和get为例；首先创建个JedisComponent组件，代码如下

/*** Created by Administrator on 2018/8/18.*/
@Component
public class JedisComponent {@AutowiredJedisPool jedisPool;public boolean set(String key, String val) {Jedis jedis = null;try {jedis = jedisPool.getResource();return jedis.set(key, val).equalsIgnoreCase("OK");} finally {if (jedis != null) {jedis.close();}}}public <T> boolean set(String key, T t) {String strJson = JacksonConvert.serilize(t);if (strJson.isEmpty()) {return false;}return this.set(key, strJson);}public String get(String key) {Jedis jedis = null;try {jedis = jedisPool.getResource();return jedis.get(key);} finally {if (jedis != null) {jedis.close();}}}public <T> T get(String key, Class<T> tClass) {String strJson = this.get(key);return JacksonConvert.deserilize(strJson, tClass);}
}

有了对jedis的调用封装，我们在Controller层的测试用例如下

    @AutowiredJedisComponent jedis;@GetMapping("/setJedis/{val}")public boolean setJedis(@PathVariable String val) {return jedis.set("token", val);}@GetMapping("/getJedis")public String getJedis() {return jedis.get("token");}

运行set和get的接口效果如
