Java-Redis Serializable序列化

在Java中使用redis存储User对象时，进行JUnit测试时，控制台：

2019-06-24 16:56:45.520 INFO 27688 --- [ main] j.LocalContainerEntityManagerFactoryBean : Initialized JPA EntityManagerFactory for persistence unit 'default'
2019-06-24 16:56:56.023 WARN 27688 --- [ main] org.thymeleaf.templatemode.TemplateMode : [THYMELEAF][main] Template Mode 'HTML5' is deprecated. Using Template Mode 'HTML' instead.

2019-06-24 16:56:57.533 INFO 27688 --- [ Thread-4] com.zaxxer.hikari.HikariDataSource : HikariPool-1 - Shutdown completed.

最后发现在JUnit栏中有错误：

发现是由于User对象未进行序列化导致的，最后User实现java.io.Serializable接口，再进行Junit测试，成功
