在使用spring-data-redis,默认情况下是使用org.springframework.data.redis.serializer.JdkSerializationRedisSerializer这个类来做序列化

我们使用jackson方式：

Jackson redis序列化是spring中自带的

@Bean(name="redisTemplate")    public RedisTemplate
     
       redisTemplate() {        Jackson2JsonRedisSerializer
      
     

使用fastjson方式：

public class FastJson2JsonRedisSerializer
     
       implements RedisSerializer
      
        {    public static final Charset DEFAULT_CHARSET = Charset.forName("UTF-8");    private Class
       
         clazz;    public FastJson2JsonRedisSerializer(Class
        
          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);    }}
        
       
      
     

注册：

@Configurationpublic class RedisConfig {    @Autowired    private RedisConnectionFactory factory;    @Autowired    private RedisSerializer fastJson2JsonRedisSerializer;    //fastjson    @Bean(name="redisTemplate")    public RedisTemplate
     
       fastJsonRedisTemplate() {        RedisTemplate
      
        template = new RedisTemplate
       
        ();        template.setConnectionFactory(factory);        //redis开启事务        template.setEnableTransactionSupport(true);        template.setKeySerializer(new StringRedisSerializer());        template.setValueSerializer(fastJson2JsonRedisSerializer);        template.setHashKeySerializer(new StringRedisSerializer());        template.setHashValueSerializer(fastJson2JsonRedisSerializer);        template.setDefaultSerializer(new StringRedisSerializer());        template.afterPropertiesSet();        return template;    }}
       
      
     

在redis工具类中调用RedisTemplate:

@Componentpublic class RedisCacheUtil {    @Autowired    @Qualifier("redisTemplate")    private  RedisTemplate
     
       redisTemplate;}
     

对比：

jackson方式序列化存储redis中数据：

[  "com.qhong.test.dependBean.Person",  {    "age": 20,    "name": "name0",    "iss": true  }]

[  "java.util.ArrayList",  [    [      "com.qhong.test.dependBean.Person",      {        "age": 20,        "name": "name0",        "iss": true      }    ],    [      "com.qhong.test.dependBean.Person",      {        "age": 21,        "name": "name1",        "iss": true      }    ],    [      "com.qhong.test.dependBean.Person",      {        "age": 22,        "name": "name2",        "iss": true      }    ]  ]]

上面的完全不符合json格式规范

fastjson方式序列化：

{  "@type": "com.qhong.test.dependBean.Person",  "age": 20,  "iss": true,  "name": "name0"}

[  {    "@type": "com.qhong.test.dependBean.Person",    "age": 20,    "iss": true,    "name": "name0"  },  {    "@type": "com.qhong.test.dependBean.Person",    "age": 21,    "iss": true,    "name": "name1"  },  {    "@type": "com.qhong.test.dependBean.Person",    "age": 22,    "iss": true,    "name": "name2"  }]

虽然也不是很好，但是比jackson的好多了
