要在Redis中使用fastjson进行序列化配置,您需要按照以下步骤执行:
1. 添加fastjson依赖:将fastjson库添加到您的项目中,可以通过在Maven项目的pom.xml文件中添加以下依赖来完成:
```xml
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>fastjson</artifactId>
<version>1.2.76</version>
</dependency>
```
2. 创建FastJsonRedisSerializer类:创建一个实现了RedisSerializer接口的FastJsonRedisSerializer类。这个类将负责将Java对象序列化为JSON字符串,并将JSON字符串反序列化回Java对象。
```java
import com.alibaba.fastjson.JSON;
import org.springframework.data.redis.serializer.RedisSerializer;import org.springframework.data.redis.serializer.SerializationException;
public class FastJsonRedisSerializer<T> implements RedisSerializer<T> {
private Class<T> clazz;
public FastJsonRedisSerializer(Class<T> clazz) {
this.clazz = clazz;
}
@Override
public byte[] serialize(T t) throws SerializationException {
if (t == null) {
return new byte[0];
}
return JSON.toJSONBytes(t);
}
@Override
public T deserialize(byte[] bytes) throws SerializationException {
if (bytes == null || bytes.length <= 0) {
return null;
}
return JSON.parseObject(bytes, clazz);
}
}
```
3. 配置RedisTemplate:在您的配置文件中配置RedisTemplate,并将FastJsonRedisSerializer设置为Redis的默认序列化器。
```java
import com.alibaba.fastjson.support.spring.FastJsonRedisSerializer;
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 {
@Bean
public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
RedisTemplate<String, Object> template = new RedisTemplate<>();
template.setConnectionFactory(redisConnectionFactory);
// 设置key的序列化器
template.setKeySerializer(new StringRedisSerializer());
template.setHashKeySerializer(new StringRedisSerializer());
// 设置value的序列化器
template.setValueSerializer(new FastJsonRedisSerializer<>(Object.class));
template.setHashValueSerializer(new FastJsonRedisSerializer<>(Object.class));
return template;
}
}
```
通过以上步骤配置好RedisTemplate后,您就可以在Spring Boot项目中使用fastjson进行Redis的序列化了。
