Spring Boot是很优秀的框架，它的出现简化了新Spring应用的初始搭建以及开发过程，大大减少了代码量，目前已被大多数企业认可和使用。这个专栏将对Spring Boot框架从浅入深，从实战到进阶，不但我们要懂得如何去使用，还要去剖析框架源码，学习其优秀的设计思想。汇总目录链接：【Spring Boot实战与进阶】学习目录
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、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、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、Java Bean
@Data
public class Student {
private Integer studentId;
private String studentName;
}
4、引入依赖
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。
<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: 63796、项目启动类
@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();
}
}7、查看Redis的数据
{"@type":"com.example.bootredis.Student","studentId":101,"studentName":"学生A"}
