springboot-redis相关配置整理

1.pom.xml引入对应数据文件

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

<dependency>
<groupId>org.springframework.boot</groupId>

3.RedisConfig配置

RedisConfig
import java.net.UnknownHostException;
import java.util.List;
import java.util.Map;

import org.springframework.cache.annotation.CachingConfigurerSupport;
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.StringRedisSerializer;

@Configuration
public class RedisConfig extends CachingConfigurerSupport {
// @Bean
// public RedisTemplate<Object,SendParameter> empRedisTemplate(RedisConnectionFactory redisConnectionFactory)
// throws UnknownHostException{
// RedisTemplate<Object,SendParameter> template = new RedisTemplate<Object, SendParameter>();
// template.setConnectionFactory(redisConnectionFactory);
// Jackson2JsonRedisSerializer<SendParameter> ser = new Jackson2JsonRedisSerializer<SendParameter>(SendParameter.class);
// template.setDefaultSerializer(ser);
// return template;
// }

@Bean
public RedisTemplate<String, List<Map<String, Object>>> redisTemplate(RedisConnectionFactory redisConnectionFactory) {

RedisTemplate<String, List<Map<String, Object>>> template = new RedisTemplate<String, List<Map<String, Object>>>();
template.setConnectionFactory(redisConnectionFactory);
template.setKeySerializer(new StringRedisSerializer());
template.setValueSerializer(new RedisObjectSerializer());
return template;
}
