我使用Spring批处理框架从db2读取并获取错误。请注意，与Mysql一样正常。 使用db2时，它在元表中创建条目。
BatchConfig.java
@Configuration
@EnableBatchProcessing
public class BatchConfiguration {
@Autowired
public JobBuilderFactory jobBuilderFactory;
@Autowired
public StepBuilderFactory stepBuilderFactory;
@Autowired
public DataSource dataSource;
@Bean
public JdbcCursorItemReader<User> reader()
{
JdbcCursorItemReader<User> reader=new JdbcCursorItemReader<>();
reader.setDataSource(dataSource);
reader.setSql("Select CORP_ACCT_ID from SAMS.AFLT_ACCT FETCH FIRST 100 ROWS ONLY");
reader.setRowMapper(new UserRowerMapper());
return reader;
}
@Bean
public UserItemProcessor processor()
{
return new UserItemProcessor();
}
@Bean
public Step step1()
{
return stepBuilderFactory.get("step1").<User,User>chunk(10)
.reader(reader())
.processor(processor())
.build();
}
@Bean
public Job job1()
{
return jobBuilderFactory.get("jobakaj")
.incrementer(new RunIdIncrementer())
.flow(step1())
.end()
.build();
}
}

请帮助!!
答案 0 :(得分：0)
这些只是一些建议，不一定会导致解决方案，
1.在提示符上执行查询以查看是否有查询数据 - Select CORP_ACCT_ID from SAMS.AFLT_ACCT FETCH FIRST 100 ROWS ONLY
2.查看查询中是否没有特殊字符或缺少空格
3.是否存在元数据表并对这六个表进行了输入？
4.尝试通过删除某个小表上的子句FETCH FIRST 100 ROWS ONLY来运行作业，以查看问题是否由该子句引起
5.根据this chart，您的驱动程序版本（4.15.82）似乎对于版本10.1 FP2是正确的，但您可以尝试升级您的驱动程序（尽管作为最后一个选项）
我按原样运行你的工作，它完成如下面的日志所示。我换了桌子和桌子架构到我有的。我准备好了DB2数据库和六个Spring批处理元数据表。
此外，我已经确认第1点无效，因为即使目标读取表为空，我也不会收到任何错误。
对于您的错误，除了驱动程序版本或sql语法之外没有其他具体内容可以说。
