spring boot中集成jedis操作redis

1:添加maven依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-redis</artifactId>
    <version>1.4.7.RELEASE</version>
</dependency>

2：在application.yml中配置redis的连接参数

spring:
    redis:
          database: 0
          hostName: 127.0.0.1
          port: 6379
          timeout: 0
          password:
          pool:
            maxTotal: 200
            maxWaitMillis: 10000
            maxIdle: 50
            minIdle: 10
            testOnBorrow: true

3：创建redis的配置类RedisConfig.java 

@Configuration
@EnableCaching
public class RedisConfig extends CachingConfigurerSupport {

		@Value("${spring.redis.database}")
	    private int database;

		@Value("${spring.redis.hostName}")

	    private int timeout;

	    @Value("${spring.redis.pool.maxIdle}")
	    private int maxIdle;

	    public JedisPoolConfig poolCofig(int maxIdle, int maxTotal,
                                         long maxWaitMillis, boolean testOnBorrow) {

	    }

	   @Bean

	       factory.setHostName(hostName);
	       factory.setPort(port);
	       factory.setPassword(password);
	       factory.setTimeout(timeout);

	       factory.setPoolConfig(poolCofig(maxIdle, maxTotal, maxWaitMillis,  testOnBorrow));
	    		           // 初始化连接pool
	       factory.afterPropertiesSet();

	       return factory;
	   }

		@Bean
	    @Override
	    public KeyGenerator keyGenerator() {
	        return (target, method, objects) -> {

	            sb.append(target.getClass().getName());
	            sb.append("::" + method.getName() + ":");
	            for (Object obj : objects) {
	                sb.append(obj.toString());
	            }
	            return sb.toString();
	        };
	    }

//	    @Bean
//	    public CacheManager cacheManager(@SuppressWarnings("rawtypes") RedisTemplate redisTemplate) {
//	        return new RedisCacheManager(redisTemplate);
//	    }

	    @Bean
	    public RedisTemplate<String, String> redisTemplate(
	            RedisConnectionFactory factory) {
	        StringRedisTemplate template = new StringRedisTemplate(factory);
	        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
	        ObjectMapper om = new ObjectMapper();
	        //om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
	        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
	        jackson2JsonRedisSerializer.setObjectMapper(om);
	        template.setValueSerializer(jackson2JsonRedisSerializer);
	        template.afterPropertiesSet();
	        return template;
	    }

	    @Bean
	    public JedisPool getJedisPool(){
	    	JedisPoolConfig config = new JedisPoolConfig();
	        config.setMaxTotal(maxTotal);
	        config.setMaxIdle(maxIdle);
	        config.setMinIdle(minIdle);
	        config.setTestOnBorrow(testOnBorrow);
	        config.setTestOnReturn(false);
	        config.setBlockWhenExhausted(true);
	        config.setMaxWaitMillis(maxWaitMillis);
	        JedisPool pool = new JedisPool(config,hostName,port,timeout,password);
	        return pool;
	    }
