升级版本由

redisson-all-3.11.6.jar升级到redisson-all-3.16.4.jar，升级后报错，找不到类，tomcat启动失败

Caused by: java.lang.NoClassDefFoundError: Lorg/nustaq/serialization/FSTConfiguration;

添加依赖

<dependency>

<groupId>de.ruedigermoeller</groupId>

<artifactId>fst</artifactId>

<version>2.43</version>

</dependency>

添加后仍然报错，

java.lang.NoClassDefFoundError: org/objenesis/Objenesis

继续添加依赖

<dependency>

<groupId>org.objenesis</groupId>

<artifactId>objenesis</artifactId>

<version>3.1</version>

</dependency>

添加后可以正常启动，至此问题解决。
