我将Spring Boot（任务）应用程序从1.5更新为Spring Boot 2.0。现在，当我运行它时，出现一个可反序列化的错误。

一个人建议： 当您的作业的执行上下文使用版本3序列化（默认情况下使用XStream），然后使用版本4进行反序列化（默认情况下使用Jackson）时，会发生此错误。因此，要么将Spring Batch降级到版本3，要么将您的作业存储库配置为使用XStreamExecutionContextStringSerializer。

在您的情况下，您已经定义了BatchConfigurer类型的bean，因此您可以覆盖createJobRepository方法并配置XStream序列化程序。例如：

@Bean
BatchConfigurer configurer(@Qualifier("dataSource") DataSource dataSource, PlatformTransactionManager transactionManager) {
    return new DefaultBatchConfigurer(dataSource) {
        @Override
        protected JobRepository createJobRepository() throws Exception {
            JobRepositoryFactoryBean factory = new JobRepositoryFactoryBean();
            factory.setDataSource(dataSource);
            factory.setTransactionManager(transactionManager);
            factory.setSerializer(new XStreamExecutionContextStringSerializer());
            factory.afterPropertiesSet();
            return factory.getObject();
        }
    };
}

我将上述bean添加到我的主类中，但仍然收到错误。

答案 0 :(得分：0)

在batch_job_execution_context表中，您可能有一些由Spring批处理版本3创建的记录。当您尝试使用Spring Batch的版本4执行新的执行时，它试图比较以前的记录。因此，它试图反序列化那些较早的记录。这就是为什么您遇到此问题。

春季批处理版本3记录就像batch_job_execution_context表中的波纹管一样

  

{“ map”：[{“ entry”：{“ string”：[“ key”，“ value”]}}]}}

春季批处理版本4记录就像batch_job_execution_context表中的波纹管一样

{"key":"value"}

删除所有由版本3创建的记录。这将解决此问题。
