My storm bolt can not deserialize in cluster mode - spring-boot

Question

I use springboot and storm to do a demo,it works in local mode,but report an error in cluster mode when i submit a jar
./storm jar storm-demo3-0.0.1-SNAPSHOT.jar org.springframework.boot.loader.JarLauncher simpleBoot
When i romove the springBoot and package with maven-compiler-plugin then it can work well
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>8</source>
<target>8</target>
</configuration>
</plugin>
</plugins>
</build>
this is the error on supervisor

Spring (boot) doesn't fit nicely with Storm. Storm is a framework, meaning it is responsible for managing the lifecycle of some classes like your bolt. As Storm doesn't know anything about Spring, Spring's dependency injection doesn't work out of the box. It is possible to set up Spring to work on parts of a Storm application with e.g. task and worker hooks, which can allow you to create a Spring context in a Storm worker. I don't think I would recommend it unless you have a good reason to need Spring.
Regarding the error you're getting, Storm is failing to find one of your classes in the jar you're submitting. Since you didn't post your pom.xml for your Spring configuration, it's hard to tell, but maybe you're using a plugin that moves your classes around. When you submit a topology to Storm, Storm runs a couple of phases you should understand:
First you do storm jar com.yourcompany.yourMain. This starts a JVM on your local machine (or wherever you're running the command), which runs your topology setup, in your case MyTopology.main. The setup then serializes your spouts and bolts, and sends the jar and serialized topology to Nimbus (a separate JVM), which in turn sends it to the supervisors (yet another separate JVM). On the supervisors, the supervisor JVM boots up a number of worker JVMs to run your topology. Each worker JVM starts with a command like java -cp your-topology.jar org.apache.storm.Worker. The worker JVMs load the serialized topology, and the classes in your topology jar, and boot up threads to run your spouts and bolts.
These phases are most likely the reason it's failing for you. When you run the topology setup code, you're doing it with a Spring Boot command, so Spring Boot gets a chance to run. When the topology starts up on the worker machines, the JVMs are started with a regular old call to a non-Spring main method, so Spring doesn't get a chance to run.
If you decide not to use Spring, you can find a working example POM here.
Other links that may be of interest are an earlier answer and a project doing Spring integration for Storm.
