无法反序列化 ExecutionContext：具有 [... Class] 且名称为 [... Class] 的类不受信任

Chr*_*ian 7 spring-batch spring-boot

我正在使用 SpringBoot2.4.2和 SpringBatch。反序列化失败并显示以下堆栈跟踪：

这个错误非常清楚，我读了很多相关内容。但是我无法解决它。

我向 BatchConfiguration 添加了该类型的 bean ExecutionContextSerializer，但它似乎不起作用：

@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();
}

该错误发生在以下情况：

@Override
    public void onApplicationEvent(ApplicationReadyEvent applicationReadyEvent) {

        Set<JobExecution> runningJobExecutions = jobExplorer.findRunningJobExecutions(job.getName());

被执行。

更新：该类现在BatchConfiguration实现该类DefaultBatchConfigurer并覆盖 getJobRepository 和 getJobExplorer （不确定这是否有必要？），如下所示：

    @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);

不幸的是，我仍然看到反序列化错误：Myclass is not trust ...如上所述。

Jackson2ExecutionContextStringSerializer我可以通过调试及其逻辑来解决问题isTrusted。最后，我必须将类型化数组和类添加到受信任的类列表中，如下所示：

public ExecutionContextSerializer customSerializer() {
    return new Jackson2ExecutionContextStringSerializer(new MyClass[0].getClass().getName(), MyClass.class.getName());
}

当我看到[L<fullyQualifiedClassName>与fullyQualifiedClassName

  • 如何覆盖 **ExecutionContextSerializer** ？创建 *@Bean* 是不够的。我尝试覆盖 *BatchConfiguration*，但之后数据库连接出现问题。 (5认同)
