Spring Boot是很優秀的框架,它的出現簡化了新Spring應用的初始搭建以及開發過程,大大減少了代碼量,目前已被大多數企業認可和使用。這個專欄將對Spring Boot框架從淺入深,從實戰到進階,不但我們要懂得如何去使用,還要去剖析框架源碼,學習其優秀的設計思想。

FastJson是阿里開源的一個高性能的JSON框架,FastJson數據處理速度快,無論序列化(把JavaBean對象轉化成Json格式的字符串)和反序列化(把JSON格式的字符串轉化爲Java Bean對象),都是當之無愧的fast;功能強大(支持普通JDK類,包括javaBean, Collection, Date 或者enum);零依賴(沒有依賴其他的任何類庫)。
1、自定義序列化類
/**
* 自定義序列化類
* @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、Redis配置類
@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值的序列化採用fastJsonRedisSerializer
template.setValueSerializer(fastJsonRedisSerializer);
template.setHashValueSerializer(fastJsonRedisSerializer);
// key的序列化採用StringRedisSerializer
template.setKeySerializer(new StringRedisSerializer());
template.setHashKeySerializer(new StringRedisSerializer());
template.setConnectionFactory(redisConnectionFactory);
return template;
}
}
3、Java Bean
@Data
public class Student {
private Integer studentId;
private String studentName;
}
4、引入依賴
pom.xml引入redis和fastjson的依賴,application.yml配置文件別忘了配置Redis的地址。
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>fastjson</artifactId>
</dependency>
5、配置文件
spring:
redis:
host: 127.0.0.1
port: 6379
6、項目啓動類
@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("學生A");
RedisTemplate cRedisTemplate = context.getBean("redisTemplate", RedisTemplate.class);
cRedisTemplate.opsForValue().set("student-1", student);
context.close();
}
}
7、查看Redis的數據
{"@type":"com.example.bootredis.Student","studentId":101,"studentName":"學生A"}
