Spring boot 无法反序列化ExecutionContext:不信任具有[…类]且名称为[…类]的类

我正在使用SpringBoot

2.4.2

和SpringBatch。反序列化失败，堆栈跟踪如下：

错误很明显，我读了很多关于它的书。但是我无法解决它

我向BatchConfiguration添加了一个类型为

ExecutionContextSerializer

的bean，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();
}

以下情况下会发生错误：

@Override
    public void onApplicationEvent(ApplicationReadyEvent applicationReadyEvent) {

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

不幸的是，我仍然看到反序列化错误：Myclass不受信任。。。如上所述。

为了注册自定义

作业存储库

，您需要提供

批配置器

并覆盖

getJobRepository

。本节对此进行了解释：

---

在您的例子中，您正在声明一个类型为

JobRepository

的bean，并期望Spring批处理将其考虑在内，这是不够的。您需要使批处理配置类实现

BatchConfigurer

或扩展

DefaultBatchConfigurer

我可以通过调试

Jackson2ExecutionContextStringSerializer

及其

受信任的逻辑来解决问题。最后，我不得不将类型化数组和类添加到可信类列表中，如下所示：

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

当我看到
[L
与
fullyQualifiedClassName
进行了比较，谢谢你的回答。我错过了文档的那部分。我用我的更改更新了我的答案。但是，我仍然得到反序列化错误。你的类是否声明为
@组件
？你需要在你的应用程序上下文。这可能会有所帮助：该类没有用
@Component
注释，而是用
@Configuration
和
@ComponentScan
注释。我添加了
@Component
，但它没有解决问题。我在前面看到了链接文章。不过，所描述的解决方案似乎只适用于spring boot更新启用ExecutionContext时，已使用旧版本（在我的场景中并非如此）保留ExecutionContext。任何提示都值得赞赏，我有点卡住了。如果没有，我无法确定问题的根本原因。如果在应用程序上下文中显式声明
BatchConfigurer
bean，并重写您使用的方法nt作为此处的代码示例：，它应该按预期工作。我可以解决此问题，因为只有类而不是类型化数组被添加到jackson序列化程序的受信任类列表中。感谢您的帮助！
You can customize any of these beans by creating a custom implementation
of the BatchConfigurer interface. Typically, extending the DefaultBatchConfigurer 
(which is provided if a BatchConfigurer is not found) and overriding
the required getter is sufficient.

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