SpringBoot整合Redis 对象序列化

实体类

@FieldNameConstants
@DynamicUpdate
@DynamicInsert
@Data
@Entity
@Table(name = "user")
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @TableId(value = "id", type = IdType.AUTO)
    @Column(name = "id", columnDefinition = "int")
    private Integer id;
    @Column(name = "name")
    private String name;

    @Column(name = "date")
    private LocalDateTime date;
}

当我保存到redis中，保存失败，因为没有序列化，在实体类中实现Serializable接口

能保存成功 但是在管理工具中看到的是一些不认识的字符

我们再来看看源码，RedissonAutoConfiguration类中，有个默认的redisTemplate，有个@ConditionalOnMissingBean注解，说明我们可以自定义个redisTemplate。

@Bean
@ConditionalOnMissingBean(
    name = {"redisTemplate"}
)
public RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory) {
    RedisTemplate template = new RedisTemplate();
    template.setConnectionFactory(redisConnectionFactory);
    return template;
}

 写个RedisConfig类，自定义配置redisTemplate，实现Jason序列化。

@Configuration
@EnableCaching
public class RedisConfig extends CachingConfigurerSupport {

    @Bean
    RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        ObjectMapper objectMapper = new ObjectMapper();
        //设置所有访问权限以及所有的实际类型都可序列化和反序列化
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        objectMapper.activateDefaultTyping(LaissezFaireSubTypeValidator.instance, ObjectMapper.DefaultTyping.NON_FINAL);
