Question

我正在使用org.springframework.batch.item.database.JdbcBatchItemWriter将文件写入数据库并使用org.springframework.batch.item.file.mapping.PassThroughFieldSetMapper映射列。数据没有插入到数据库中，也没有在日志中出现任何错误。

<bean id="ItemWriter" class="org.springframework.batch.item.database.JdbcBatchItemWriter">
    <property name="dataSource" ref="dataSource" />
    <property name="sql">
        <value>
            <![CDATA[
                insert into Student_Details(Name,Id,ClassId,Rank) values (:Name, :Id, :ClassId, :Rank)
            ]]>
        </value>
    </property>     
    <property name="itemSqlParameterSourceProvider">
        <bean class="org.springframework.batch.item.database.BeanPropertyItemSqlParameterSourceProvider" />
    </property>

我在BATCH_STEP_EXECUTION表中看到READ_COUNT个值，但WRITE_COUNT为0，WRITE_SKIP_COUNT与读取计数相同。

-Amuthan

当您的READ_COUNT与您的WRITE_SKIP_COUNT匹配时，它意味着您的JdbcBatchItemWriter中已抛出异常，该异常已在skippable-exception-classes属性中注册为可跳过的异常。< / p>

<step id="step1">
   <tasklet>
      <chunk reader="soemReader" writer="jdbcWriter"
             commit-interval="10" skip-limit="10">
         <skippable-exception-classes>
            <include class="com.package.YourException"/>
         </skippable-exception-classes>
      </chunk>
   </tasklet>
</step>

我删除任何可跳过的例外，除非您有真正的业务来吞下这样的错误。
