Spring-boot通过redisTemplate使用redis(无须手动序列化)

导入redis依赖

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

Jackson依赖

<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.3.2</version>
</dependency>

配置application.yml配置文件

# REDIS (RedisProperties)
spring:
redis:
database: 0      # Redis数据库索引（默认为0）
host: localhost  # Redis服务器地址
port: 6379       # Redis服务器连接端口
password:        # Redis服务器连接密码（默认为空）
timeout: 0       # 连接超时时间（毫秒）
pool:
max-active: 8  # 连接池最大连接数（使用负值表示没有限制）
max-idle: 8    # 连接池中的最大空闲连接
max-wait: -1   # 连接池最大阻塞等待时间（使用负值表示没有限制）
min-idle: 0    # 连接池中的最小空闲连接

使redisTemplate无须手动序列化的类,并用jackson替换默认的序列化工具

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
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.StringRedisSerializer;

/**
* Created by zhengwei on 2017/10/17.
*/
@Configuration
public class RedisConfig {

/**
* redisTemplate 序列化使用的jdkSerializeable, 存储二进制字节码, 所以自定义序列化类
* @param redisConnectionFactory
* @return
*/
@Bean
public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();
redisTemplate.setConnectionFactory(redisConnectionFactory);

// 使用Jackson2JsonRedisSerialize 替换默认序列化
Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);

ObjectMapper objectMapper = new ObjectMapper();
objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);

jackson2JsonRedisSerializer.setObjectMapper(objectMapper);

// 设置value的序列化规则和 key的序列化规则
redisTemplate.setKeySerializer(new StringRedisSerializer());
redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
redisTemplate.afterPropertiesSet();
return redisTemplate;
}
}

开始使用

import com.example.entity.User;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
public class RedisApplicationTests {

@Autowired
private RedisTemplate<Object, Object> template;

@Test
public void contextLoads() {
User user = new User(1,"象拔蚌");
template.opsForValue().set(user.getId()+"",user);
//原本opsForValue()是只能操作字符串的.现在就可以操作对象了
User result = (User) template.opsForValue().get(user.getId()+"");
System.out.println(result.toString());
}
}

User{id=1, name='象拔蚌'}
