问题：

自定义异常跳过Spring批处理作业无法正常工作

颛孙庆
2023-03-14

如果Spring批处理作业业务逻辑出现ArrayIndexOutOfBoundsException，我必须从我的自定义映射器FieldSetMapper of reader FlatFileItemReader中跳过一个自定义异常（CSVFieldMappingException）。为此，我添加了作业步骤的配置，如下所示。

@Bean
public Step step1(StepBuilderFactory stepBuilderFactory,
                  ItemReader reader, ItemWriter writer,
                  ItemProcessor processor, @Value("${reader.chunkSize}")
                  int chunkSize) {
    LOGGER.info("Step configuration loaded with chunk size {}", chunkSize);
    return stepBuilderFactory.get("step1")
            .chunk(chunkSize).reader(reader)
            .processor(processor).writer(writer)
            .faultTolerant()
            .skip(CSVFieldMappingException.class)
            .skipLimit(1000)
            .build();

但这不起作用，因为每当我抛出自定义RunTimeException时，就会引发另一个运行时异常FlatFileParseException。为了解决这个问题，我还必须在上述配置的skip中添加FlatFileParseException。但这会在引发任何其他异常时破坏我的其他场景。我如何解决这个问题？我无法将CustomException改为runtime exception，因为FieldSetMapper接口没有这样的实现。

上述情况下的堆栈跟踪如下所示。我可以看到我的CustomException被更改为链中的其他一些异常。

在进一步查看FlatFileItemReader从FlatFileItemR抛出的异常后eader.lineMapper被包装到FlatFileParseException中。
您可以编写自己的ItemReader，将open（）委托给真正的阅读器并捕获FlatFileParseException：如果导致错误是您的CSVFieldMappingException将其抛回或重新抛出原始异常。
