JedisPoolConfig参数配置详情

JedisPoolConfig config = new JedisPoolConfig();
//连接耗尽时是否阻塞, false报异常,ture阻塞直到超时, 默认true
config.setBlockWhenExhausted(true);
//设置的逐出策略类名, 默认DefaultEvictionPolicy(当连接超过最大空闲时间,或连接数超过最大空闲连接数)
config.setEvictionPolicyClassName("org.apache.commons.pool2.impl.DefaultEvictionPolicy");
//是否启用pool的jmx管理功能, 默认true
config.setJmxEnabled(true);
//MBean ObjectName = new ObjectName("org.apache.commons.pool2:type=GenericObjectPool,name=" + "pool" + i); 默认为"pool",
config.setJmxNamePrefix("pool");
//是否启用后进先出, 默认true
config.setLifo(true);
//最大空闲连接数, 默认8个
config.setMaxIdle(8);
//最大连接数, 默认8个
config.setMaxTotal(8);
//获取连接时的最大等待毫秒数(如果设置为阻塞时BlockWhenExhausted),如果超时就抛异常, 小于零:阻塞不确定的时间, 默认-1
config.setMaxWaitMillis(-1);
//逐出连接的最小空闲时间 默认1800000毫秒(30分钟)
config.setMinEvictableIdleTimeMillis(1800000);
//最小空闲连接数, 默认0
config.setMinIdle(0);
//每次逐出检查时 逐出的最大数目 如果为负数就是 : 1/abs(n), 默认3
config.setNumTestsPerEvictionRun(3);
//对象空闲多久后逐出, 当空闲时间>该值 且 空闲连接>最大空闲数 时直接逐出,不再根据MinEvictableIdleTimeMillis判断(默认逐出策略)
config.setSoftMinEvictableIdleTimeMillis(1800000);
//在获取连接的时候检查有效性, 默认false
config.setTestOnBorrow(false);
//在空闲时检查有效性, 默认false
config.setTestWhileIdle(false);
//逐出扫描的时间间隔(毫秒) 如果为负数,则不运行逐出线程, 默认-1
config.setTimeBetweenEvictionRunsMillis(-1);
JedisPool pool = new JedisPool(config, "localhost",);
int timeout=3000;
new JedisSentinelPool(master, sentinels, poolConfig,timeout);//timeout 读取超时

查看JedisPoolConfig 源代码可以看出继承关系和初始值状态

package redis.clients.jedis;
