报错位置： jedis = jedisPool.getResource();
/**
* 设置对象
* */
public <T> boolean set(KeyPrefix prefix, String key, T value) {
Jedis jedis = null;
try {
jedis = jedisPool.getResource();
if(jedis==null){
logger.info("redis service set jedis is null ");
return false;
}
String str = beanToString(value);
if(str == null || str.length() <= 0) {
return false;
}
//生成真正的key
String realKey = prefix.getPrefix() + key;
int seconds = prefix.expireSeconds();
if(seconds <= 0) {
jedis.set(realKey, str);
}else {
jedis.setex(realKey, seconds, str);
}
return true;
}finally {
returnToPool(jedis);
}
}
4.问题原因
本机redis 配置文件没有设置密码，代码的额配置文件有，解决方法如果不要密码则配置文件加上“#”注释或者修改本机redis.conf
的requirepass 123456,总之两边要匹配。
redis.password=123456
# redis
redis.host=127.0.0.1
redis.port=6379
# redis.password=123456
redis.timeout=3
redis.poolMaxTotal=10
redis.poolMaxIdle=10
redis.poolMaxWait=3
5.修改后
