Spring整合redisTemplate

一.RedisConfig

package com.itheima.config;

import org.apache.commons.pool2.impl.GenericObjectPoolConfig;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.PropertySource;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.connection.RedisStandaloneConfiguration;
import org.springframework.data.redis.connection.jedis.JedisClientConfiguration;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

@PropertySource("redis.properties")
public class RedisConfig {

    @Value("${redis.host}")
    private String hostName;

    @Value("${redis.port}")
    private Integer port;

//    @Value("${redis.password}")
//    private String password;

    @Value("${redis.maxActive}")
    private Integer maxActive;
    @Value("${redis.minIdle}")
    private Integer minIdle;
    @Value("${redis.maxIdle}")
    private Integer maxIdle;
    @Value("${redis.maxWait}")
    private Integer maxWait;



    @Bean
    //配置RedisTemplate
    public RedisTemplate createRedisTemplate(RedisConnectionFactory redisConnectionFactory){
        //1.创建对象
        RedisTemplate redisTemplate = new RedisTemplate();
        //2.设置连接工厂
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        //3.设置redis生成的key的序列化器，对key编码进行处理
        RedisSerializer stringSerializer = new StringRedisSerializer();
        redisTemplate.setKeySerializer(stringSerializer);
        redisTemplate.setHashKeySerializer(stringSerializer);
        //4.返回
        return redisTemplate;
    }

    @Bean
    //配置Redis连接工厂
    public RedisConnectionFactory createRedisConnectionFactory(RedisStandaloneConfiguration redisStandaloneConfiguration,GenericObjectPoolConfig genericObjectPoolConfig){
        //1.创建配置构建器，它是基于池的思想管理Jedis连接的
        JedisClientConfiguration.JedisPoolingClientConfigurationBuilder builder = (JedisClientConfiguration.JedisPoolingClientConfigurationBuilder)JedisClientConfiguration.builder();
        //2.设置池的配置信息对象
        builder.poolConfig(genericObjectPoolConfig);
        //3.创建Jedis连接工厂
        JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory(redisStandaloneConfiguration,builder.build());
        //4.返回
        return jedisConnectionFactory;
    }

    @Bean
    //配置spring提供的Redis连接池信息
    public GenericObjectPoolConfig createGenericObjectPoolConfig(){
        //1.创建Jedis连接池的配置对象
        GenericObjectPoolConfig genericObjectPoolConfig = new GenericObjectPoolConfig();
        //2.设置连接池信息
        genericObjectPoolConfig.setMaxTotal(maxActive);
        genericObjectPoolConfig.setMinIdle(minIdle);
        genericObjectPoolConfig.setMaxIdle(maxIdle);
        genericObjectPoolConfig.setMaxWaitMillis(maxWait);
        //3.返回
        return genericObjectPoolConfig;
    }


    @Bean
    //配置Redis标准连接配置对象
    public RedisStandaloneConfiguration createRedisStandaloneConfiguration(){
        //1.创建Redis服务器配置信息对象
        RedisStandaloneConfiguration redisStandaloneConfiguration = new RedisStandaloneConfiguration();
        //2.设置Redis服务器地址，端口和密码（如果有密码的话）
        redisStandaloneConfiguration.setHostName(hostName);
        redisStandaloneConfiguration.setPort(port);
//        redisStandaloneConfiguration.setPassword(RedisPassword.of(password));
        //3.返回
        return redisStandaloneConfiguration;
    }

}

二.Service层使用

package com.itheima.service.impl;


import com.itheima.domain.Account;
import com.itheima.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Service;
@Service("accountService")
public class AccountServiceImpl implements AccountService {

    @Autowired
    private RedisTemplate redisTemplate;

    public void save(Account account) {
    }

    public void changeMoney(Integer id, Double money) {
        //等同于redis中set account:id:1 100
        redisTemplate.opsForValue().set("account:id:"+id,money);


    }

    public Double findMondyById(Integer id) {
        //等同于redis中get account:id:1
        Object money = redisTemplate.opsForValue().get("account:id:" + id);
        return new Double(money.toString());
    }
}
//        redisTemplate.type()
//        redisTemplate.persist()
//        redisTemplate.move()
//        redisTemplate.hasKey()
//        redisTemplate.getExpire()
//        redisTemplate.expire()
//        redisTemplate.delete()
//        redisTemplate.rename();
//
//        redisTemplate.opsForValue().;
//        redisTemplate.opsForHash().;
//        redisTemplate.opsForList().;
//        redisTemplate.opsForSet().;
//        redisTemplate.opsForZSet();
//
//
//        redisTemplate.boundValueOps().;
//
//        redisTemplate.slaveOf();
//        redisTemplate.slaveOfNoOne();
//
//        redisTemplate.opsForCluster()
