SpringBoot Redis配置Fastjson进行序列化和反序列化实现
FastJson是阿里开源的一个高性能的JSON框架,FastJson数据处理速度快,无论序列化(把JavaBean对象转化成Json格式的字符串)和反序列化(把JSON格式的字符串转化为Java Bean对象),都是当之无愧的fast;功能强大(支持普通JDK类,包括javaBean, Collection, Date 或者enum);零依赖(没有依赖其他的任何类库)。
1、写一个自定义序列化类
/** * 自定义序列化类 * @param <T> */ public class FastJsonRedisSerializer<T> implements RedisSerializer<T> { public static final Charset DEFAULT_CHARSET = Charset.forName("UTF-8"); private Class<T> clazz; public FastJsonRedisSerializer(Class<T> clazz) { super(); this.clazz = clazz; } @Override public byte[] serialize(T t) throws SerializationException { if (null == t) { return new byte[0]; } return JSON.toJSONString(t, SerializerFeature.WriteClassName).getBytes(DEFAULT_CHARSET); } @Override public T deserialize(byte[] bytes) throws SerializationException { if (null == bytes || bytes.length <= 0) { return null; } String str = new String(bytes, DEFAULT_CHARSET); return (T) JSON.parseObject(str, clazz); } }
2、写一个Redis配置类
@Configuration public class RedisConfiguration { @Bean public RedisTemplate<Object, Object> redisTemplate( RedisConnectionFactory redisConnectionFactory) { RedisTemplate<Object, Object> template = new RedisTemplate<>(); //使用fastjson序列化 FastJsonRedisSerializer fastJsonRedisSerializer = new FastJsonRedisSerializer(Object.class); // value值的序列化采用fastJsonRedisSerializer template.setValueSerializer(fastJsonRedisSerializer); template.setHashValueSerializer(fastJsonRedisSerializer); // key的序列化采用StringRedisSerializer template.setKeySerializer(new StringRedisSerializer()); template.setHashKeySerializer(new StringRedisSerializer()); template.setConnectionFactory(redisConnectionFactory); return template; } }
3、Student类
@Data public class Student { private Integer studentId; private String studentName; }
4、pom.xml引入redis和fastjson的依赖,application.yml配置文件别忘了配置Redis的地址。
5、BootRedisApplication启动类
@SpringBootApplication public class BootRedisApplication { public static void main(String[] args) { ConfigurableApplicationContext context = SpringApplication.run(BootRedisApplication.class, args); Student student = new Student(); student.setStudentId(101); student.setStudentName("学生A"); RedisTemplate cRedisTemplate = context.getBean("redisTemplate", RedisTemplate.class); cRedisTemplate.opsForValue().set("student-1", student); context.close(); } }
6、查看Redis的数据
{"@type":"com.example.bootredis.Student","studentId":101,"studentName":"学生A"}
