I'm working with SpringBoot 2.4.2 and SpringBatch. Deserialization fails with the following stacktrace:
2021-03-29 15:51:28.529 ERROR 30308 --- [ main] o.s.boot.SpringApplication : Application run failed

The error is pretty clear and I read a lot about it. However I am not able to solve it.
I added a bean of the type ExecutionContextSerializer to the BatchConfiguration but it does not seem to work:
@Bean
public ExecutionContextSerializer customSerializer(){
return new Jackson2ExecutionContextStringSerializer(ClassToBeTrusted.class.getName());
}
@Bean
public JobRepository createJobRepository(DataSource dataSource,ExecutionContextSerializer executionContextSerializer) throws Exception {
JobRepositoryFactoryBean factory = new JobRepositoryFactoryBean();
factory.setDataSource(dataSource);
factory.setTransactionManager(getTransactionManager());
factory.setSerializer(executionContextSerializer);
factory.afterPropertiesSet();
return factory.getObject();
}
The error occurs when:
@Override
public void onApplicationEvent(ApplicationReadyEvent applicationReadyEvent) {
Set<JobExecution> runningJobExecutions = jobExplorer.findRunningJobExecutions(job.getName());
is executed.
Update: the BatchConfiguration class implements the DefaultBatchConfigurer class now and overrides getJobRepository and getJobExplorer (not sure if this is necessary?) as followed:
@Override
public JobRepository getJobRepository() {
try {
JobRepositoryFactoryBean factory = new JobRepositoryFactoryBean();
factory.setDataSource(datasource);
factory.setTransactionManager(getTransactionManager());
factory.setSerializer(customSerializer());
factory.afterPropertiesSet();
return factory.getObject();
}
catch(Exception e){
throw new BatchConfigurationException(e);
}
}
@Override
public JobExplorer getJobExplorer(){
try{
JobExplorerFactoryBean factory = new JobExplorerFactoryBean();
factory.setSerializer(customSerializer());
factory.setDataSource(datasource);
factory.afterPropertiesSet();
return factory.getObject();
}
catch(Exception e ){
throw new BatchConfigurationException(e);
}
}
Unfortunately I still see the deserialization error: Myclass is not trusted ... as stated above.
I could solve the problem by debugging the Jackson2ExecutionContextStringSerializer and its isTrusted logic. In the end I had to add the typed array and the class to the list of trusted classes like this:
public ExecutionContextSerializer customSerializer() {
return new Jackson2ExecutionContextStringSerializer(new MyClass[0].getClass().getName(), MyClass.class.getName());
}
I became aware of the problem when I saw that [L<fullyQualifiedClassName> was compared with fullyQualifiedClassName
