SpringBoot Redis配置Fastjson进行序列化和反序列化实现

2019-10-25 18:07 3467 查看

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"}
