弹出批处理ItemProcessor在从阅读器发送项目列表时抛出异常

Question

以下是原始问题For CompositeItemReader Issue 我已经询问过与CompositeItemReader相关的问题，我在@LucaBassoRicci的帮助下解决了这个问题。现在读者正在工作但是当我将项目列表一起发送到我的处理器时，它会抛出异常。

我的处理器代码

@Component("fi008RecordProcessor")
@StepScope
public class FI008RecordProcessor implements ItemProcessor<List<Fi008ActvityTxnDtlsVO>, List<FI008Record>>,
    ItemProcessListener<List<Fi008ActvityTxnDtlsVO>, List<FI008Record>> {

@Value("#{jobParameters}")
private Map<String, JobParameter> jobParameters;

@Value("#{jobExecutionContext}")
private ExecutionContext jobExecutionContext;

@Autowired
private DaoHelper daoHelper;

@Override
public List<FI008Record> process(final List<Fi008ActvityTxnDtlsVO> items) throws Exception {
}

 @Override
public void beforeProcess(final List<Fi008ActvityTxnDtlsVO> item) {

}

@Override
public void afterProcess(final List<Fi008ActvityTxnDtlsVO> item, final List<FI008Record> result) {
}

@Override
public void onProcessError(final List<Fi008ActvityTxnDtlsVO> item, final Exception e) {
    // update the event table
    // update the records in settle hist table
}

我得到了例外。

有人可以让我知道我的代码有什么问题。
