SpringBoot集成中间件

使用的依赖

    redis.clients
    jedis

在applicaiton.properties文件中添加Redis配置

spring.datasource.redis.host=localhost
spring.datasource.redis.port=6379
spring.datasource.redis.username=redis
spring.datasource.redis.password=redis
spring.datasource.redis.database=0
spring.datasource.redis.pool-max-idle=100
spring.datasource.redis.pool-max-wait=-1
spring.datasource.redis.pool-min-idle=0
spring.datasource.redis.timeout=5000

创建一个RedisConfig配置类。用于读取application.properties的配置。

@Data
@Component
@ConfigurationProperties(prefix = "spring.datasource.redis")
@Primary
public class RedisConfig {
    private String host;
    private Integer port=6379;
    private String username;
    private String password;
    private Integer database=0;
    private Integer poolMaxIdle=100;
    private Integer poolMaxWait=-1;
    private Integer poolMinIdle=0;
    private Integer timeout=5000;
}

创建RedisPool线程池类，用于配置Redis线程池。

@Component
@EnableConfigurationProperties(RedisConfig.class)
public class RedisPool {

    @Bean(destroyMethod = "close")
    public JedisPool getJedisPool(RedisConfig redisConfig){
        JedisPoolConfig jedisPoolConfig=new JedisPoolConfig();
        // 是否启用pool的jmx管理功能, 默认true
        jedisPoolConfig.setJmxEnabled(true);
        jedisPoolConfig.setMaxIdle(100);
        jedisPoolConfig.setMaxWait(BaseObjectPoolConfig.DEFAULT_MAX_WAIT);
        jedisPoolConfig.setBlockWhenExhausted(false);
        return new JedisPool(jedisPoolConfig,redisConfig.getHost(),redisConfig.getPort(),redisConfig.getUsername(), redisConfig.getPassword());
    }
}

在使用JedisPool的时候遇到连接不主动释放，实例必须要手动归还的问题。即jedis高版本的jedis.close()来归还。

所以编写了工具类，实现了对Jedis所有接口的封装，可以自动释放连接，配合上述配置，可以直接使用。下载地址。

    public Boolean copy(String srcKey, String dstKey, int db, boolean replace) {
        try (Jedis jedis = jedisPool.getResource()) {
            return jedis.copy(srcKey, dstKey, db, replace);
        } catch (Exception e) {
            e.printStackTrace();
            throw e;
        }
    }

    public String set(String key, String value) {
        try (Jedis jedis = jedisPool.getResource()) {
            return jedis.set(key, value);
        } catch (Exception e) {
            e.printStackTrace();
            throw e;
        }
    }

    public String get(String key) {
        try (Jedis jedis = jedisPool.getResource()) {
            return jedis.get(key);
        } catch (Exception e) {
            e.printStackTrace();
            throw e;
        }
    }
}
