Question

我的应用程序无法启动。使用文件名创建一个bean给我一个错误。我搜索并找到了与此问题类似的帖子，但它们似乎与我的错误无关，所以我希望有人可以找到可能导致此文件失败的原因。另外，我在两种方法之间处于交叉状态。我是否使用FlatFileReader或MomgoItemreader？我只需要从数据库的名字和姓氏中检索两件事。我需要读取数据库，然后将其写入尚未完成的文件。任何帮助将不胜感激。

处理器：

package com.spring_batchjob.job.item;

import org.springframework.batch.item.ItemProcessor;

import com.spring_batchjob.bean.PaymentAudit;




public class PaymentPortalNOSQLProcessor implements 
ItemProcessor<PaymentAudit, PaymentAudit> {


@Override
public PaymentAudit process(PaymentAudit bean) throws Exception {
    return bean;

}

}

回购：

import java.util.List;

import org.springframework.data.mongodb.repository.MongoRepository;
import org.springframework.stereotype.Repository;

import com.spring_batchjob.bean.PaymentAudit;

@Repository

MongoRepository<PaymentAudit, String> {

//  List<PaymentAudit> findByCreateDttmBetween(LocalDateTime createStart, 
   LocalDateTime createEnd);
   List<PaymentAudit> findByRxFNameAndRxLName(String rxFName, String 
   rxLName);

}
