这编博客主要介绍了springboot整合redis（以注解的形式）。

一、引入redis依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-redis</artifactId>
    <version>RELEASE</version>
</dependency>

二、redis配置文件

创建一个新properties（redis.properties） ，写入redis配置文件，如下： 
redis.host=127.0.0.1
redis.port=6379
redis.password=12345
redis.database=3
redis.maxActive=8
redis.maxWait=-1
redis.maxIdle=8
redis.minIdle=1
redis.timeOut=0

创建与redis.properties的配置类方便直接使用配置的参数。

package com.standard.address.config;

import com.alibaba.fastjson.parser.ParserConfig;
import com.standard.address.utils.FastJson2JsonRedisSerializer;
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.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;
import redis.clients.jedis.JedisPoolConfig;

/**
 * Created by glin on 2018/11/24 0024.
 */
@Configuration
public class RedisConfig {
    @Autowired
    private RedisConfigProperties redis;
    @Bean
    public RedisSerializer fastJson2JsonRedisSerializer() {     ParserConfig.getGlobalInstance().setAutoTypeSupport(true);
        return new FastJson2JsonRedisSerializer<Object>(Object.class);
    }
    @Bean
    public RedisConnectionFactory redisConnectionFactory() {
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        //最大空闲接连
        jedisPoolConfig.setMaxIdle(redis.getMaxIdle());
        //最小空闲连接
        jedisPoolConfig.setMinIdle(redis.getMinIdle());
        //连接池最大阻塞等待时间
        jedisPoolConfig.setMaxWaitMillis(redis.getMaxWait());
        JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory();
        //主机地址
        jedisConnectionFactory.setHostName(redis.getHost());
        //端口
        jedisConnectionFactory.setPort(redis.getPort());
        //密码
        jedisConnectionFactory.setPassword(redis.getPassword());
        //索引
        jedisConnectionFactory.setDatabase(redis.getDatabase());
        //超时时间
        jedisConnectionFactory.setTimeout(redis.getTimeOut());
        jedisConnectionFactory.setUsePool(true);
        jedisConnectionFactory.setPoolConfig(jedisPoolConfig);
        return jedisConnectionFactory;
    }
    @Bean
    public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory factory, RedisSerializer fastJson2JsonRedisSerializer) {
        StringRedisTemplate redisTemplate = new StringRedisTemplate(factory);        redisTemplate.setConnectionFactory(redisConnectionFactory());
        //redis   开启事务
        redisTemplate.setEnableTransactionSupport(true);
        //hash  使用jdk  的序列化
        redisTemplate.setHashValueSerializer(fastJson2JsonRedisSerializer/*new JdkSerializationRedisSerializer()*/);
        //StringRedisSerializer  key  序列化
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        //keySerializer  对key的默认序列化器。默认值是StringSerializer
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        //  valueSerializer
        redisTemplate.setValueSerializer(fastJson2JsonRedisSerializer);
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }

}

三、配置整合

使用fastjson的序列化，创建一个自定义序列化配置类

package com.standard.address.utils;

import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.serializer.SerializerFeature;
import org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.data.redis.serializer.SerializationException;

import java.nio.charset.Charset;

/**
 * fastjson的json序列化
 * Created by glin on 2018/11/24 0024.
 */
public class FastJson2JsonRedisSerializer<T> implements RedisSerializer<T> {
    public static final Charset DEFAULT_CHARSET = Charset.forName("UTF-8");
    private Class<T> clazz;
    public FastJson2JsonRedisSerializer(Class<T> clazz) {
        super();
        this.clazz = clazz;
    }
    public byte[] serialize(T t) throws SerializationException {
        if (t == null) {
            return new byte[0];
        }
        return JSON.toJSONString(t, SerializerFeature.WriteClassName).getBytes(DEFAULT_CHARSET);
    }
    public T deserialize(byte[] bytes) throws SerializationException {
        if (bytes == null || bytes.length <= 0) {
            return null;
        }
        String str = new String(bytes, DEFAULT_CHARSET);
        return (T) JSON.parseObject(str, clazz);
    }
}

项目整合

package com.standard.address.config;

import com.alibaba.fastjson.parser.ParserConfig;
import com.standard.address.utils.FastJson2JsonRedisSerializer;
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.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;
import redis.clients.jedis.JedisPoolConfig;

/**
 * Created by glin on 2018/11/24 0024.
 */
@Configuration
public class RedisConfig {
    @Autowired
    private RedisConfigProperties redis;
    @Bean
    public RedisSerializer fastJson2JsonRedisSerializer() {     ParserConfig.getGlobalInstance().setAutoTypeSupport(true);
        return new FastJson2JsonRedisSerializer<Object>(Object.class);
    }
    @Bean
    public RedisConnectionFactory redisConnectionFactory() {
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        //最大空闲接连
        jedisPoolConfig.setMaxIdle(redis.getMaxIdle());
        //最小空闲连接
        jedisPoolConfig.setMinIdle(redis.getMinIdle());
        //连接池最大阻塞等待时间
        jedisPoolConfig.setMaxWaitMillis(redis.getMaxWait());
        JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory();
        //主机地址
        jedisConnectionFactory.setHostName(redis.getHost());
        //端口
        jedisConnectionFactory.setPort(redis.getPort());
        //密码
        jedisConnectionFactory.setPassword(redis.getPassword());
        //索引
        jedisConnectionFactory.setDatabase(redis.getDatabase());
        //超时时间
        jedisConnectionFactory.setTimeout(redis.getTimeOut());
        jedisConnectionFactory.setUsePool(true);
        jedisConnectionFactory.setPoolConfig(jedisPoolConfig);
        return jedisConnectionFactory;
    }
    @Bean
    public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory factory, RedisSerializer fastJson2JsonRedisSerializer) {
        StringRedisTemplate redisTemplate = new StringRedisTemplate(factory);        redisTemplate.setConnectionFactory(redisConnectionFactory());
        //redis   开启事务
        redisTemplate.setEnableTransactionSupport(true);
        //hash  使用jdk  的序列化
        redisTemplate.setHashValueSerializer(fastJson2JsonRedisSerializer/*new JdkSerializationRedisSerializer()*/);
        //StringRedisSerializer  key  序列化
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        //keySerializer  对key的默认序列化器。默认值是StringSerializer
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        //  valueSerializer
        redisTemplate.setValueSerializer(fastJson2JsonRedisSerializer);
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }

}

五、测试

@Resource
RedisHandle rs;

@Test
public void RedisTest() throws Exception {
    rs.set("aaa", "1");
    Object o = rs.get("aaa");
    System.out.println(o);
}
