没有配置流
今天用到一个配置,我当时没有注册进入两个流,
?
运行的时候,发现这个错误
?
org.springframework.batch.item.WriterNotOpenException: Writer must be open before it can be written to
?
Converted from a single FlatFileItemWriter to a database and flatfileitemwriter and didn't register the flatfile one as a stream.
If using a single FlatFileItemWriter it is enough to register it as an ItemWriter however when using the composite the adding it as a stream is also needed.
?
所以必须配置
?
<chunk reader="heterogeneousItemReader" writer="reterogeneousItemWriter"
commit-interval="1" >
<streams>
? ? ? ? ? ? ? ? ? ? ? ?<stream ref="studentwriter" />
? ? ? ? ? ? ? ? ? ? ? ?<stream ref="goodswriter" />
? ? ? ? ? ? ? ? ? ? </streams>
</chunk>
