spring 项目启动 链接redis 特别慢

redis:
database: 0
host: localhost
port: 6379
password: root
pool:
max-active: 8
max-wait: -1
max-idle: 8
min-idle: 0
timeout: 5000
server:
port: 8081
注入RedisTemplate，还要有初始化RedisConnectionFactory
package com.rosam.config;
import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.JdkSerializationRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;
/**
• 自己的redisTemplate
• 
• @author Song.aw
• @create 2017-12-07 9:37
**/
@Configuration
public class RedisConfig{
@Autowired
RedisConnectionFactory redisConnectionFactory;
@Bean
public RedisTemplate<String, Object> functionDomainRedisTemplate() {
RedisTemplate<String, Object> redisTemplate = new RedisTemplate<String, Object>();
initDomainRedisTemplate(redisTemplate, redisConnectionFactory);
return redisTemplate;
}
private void initDomainRedisTemplate(RedisTemplate<String, Object> redisTemplate, RedisConnectionFactory factory) {
redisTemplate.setKeySerializer(new StringRedisSerializer());
redisTemplate.setHashKeySerializer(new StringRedisSerializer());
redisTemplate.setHashValueSerializer(new JdkSerializationRedisSerializer());
redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer());
redisTemplate.setConnectionFactory(factory);
}
}
在Controller中的使用
package com.rosam.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.ZSetOperations;
import org.springframework.data.redis.support.atomic.RedisAtomicLong;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;
import java.util.Map;
import java.util.Set;
import java.util.concurrent.TimeUnit;
@Controller
@RequestMapping(“/user”)
public class UserController {
@Autowired
private RedisTemplate redisTemplate;
/**
• 登录后保存用户名为userName,value为password
• @param userName
• @param password
• @return
*/
@GetMapping(“/login”)
@ResponseBody
public String login(@RequestParam(“userName”)String userName, @RequestParam(“password”)String password){
redisTemplate.opsForValue().set(userName, password);
redisTemplate.expire(userName,10,TimeUnit.SECONDS);
return “success”;
}
/**
• 原子自增，设置过期时间
• @param params
• @return
*/
@RequestMapping(value = “/incrementScore”, method = RequestMethod.POST)
@ResponseBody
public String incrementScore(@RequestBody Map<String, Object> params) {
String key = params.get(“key”).toString();
Long value =(Long) redisTemplate.opsForValue().get(key);
RedisAtomicLong entityIdCounter = new RedisAtomicLong(key, redisTemplate.getConnectionFactory());
entityIdCounter.expire(3, TimeUnit.SECONDS);//过期时间为3秒
Long increment = entityIdCounter.getAndIncrement();
redisTemplate.opsForValue().set(key,increment+value);
return “success”;
}
/**
• 实现排序，热度，积分榜等功能，更多方法可以可以搜索zSetOperations
• @return
*/
@GetMapping(value = “rankScore”)
@ResponseBody
public String rank(){
ZSetOperations zSetOperations = redisTemplate.opsForZSet();
zSetOperations.add(“score”,“one”,1);
zSetOperations.add(“score”,“four”,4);
zSetOperations.add(“score”,“three”,110);
zSetOperations.add(“score”,“five”,5);
zSetOperations.add(“score”,“six”,6);
//从子集中找到Smin<=score<=Smax的元素集合
//value在此区间中的。
Set set = zSetOperations.rangeByScore(“score”, 100,120);
System.out.println(“打印v1的值在100-120区间的”+set.size());
//索引start<=index<=end的元素子集，返回泛型接口（包括score和value），正序
//返回score和value，set中的前两个
Set set1 = zSetOperations.rangeWithScores(“score”,0,1);
//键为K的集合，索引start<=index<=end的元素子集，正序
//返回排序后的value中的前两个
Set set2 = zSetOperations.range(“score”,0,1);
//键为K的集合，索引start<=index<=end的元素子集，倒序
//返回排序后的最后两个
Set set3 = zSetOperations.reverseRange(“score”,0,1);
return null;
}
/**
• 根据key获取value
• @param key
• @return
*/
@GetMapping(“/get”)
@ResponseBody
public String getRedisVal(@RequestParam String key){
String value = redisTemplate.opsForValue().get(key).toString();
return value;
}
/**
• 根据key设置value
• @param key
• @param value
• @return
*/
@GetMapping(“/set”)
@ResponseBody
public String setRedisVal(@RequestParam String key, @RequestParam Integer value){
redisTemplate.opsForValue().set(key , value);
