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"}
