Spring Batch - 最后来自阅读器的项目正在更新

如果文件中存在的ID与列中的ID匹配，我必须从文件（FlatFile）中读取并更新列。文件正在被正确读取，但只有最后一个id值在这里更新。请找到片段Spring Batch - 最后来自阅读器的项目正在更新

工作-config.xml中

<bean id="abcitemReader" class="org.springframework.batch.item.file.FlatFileItemReader" scope="step"> 
     <property name="resource" value="file:datafile/outputs/ibdData.txt" />

    <!-- It will take care matching between object property and sql name parameter --> 
    <property name="itemPreparedStatementSetter" ref="testPrepStatementSetter" /> 
</bean> 
</beans>

Setter.java

public class IDItemPreparedStatementSetter implements ItemPreparedStatementSetter<Test> { 
    @Override 
    public void setValues(Test item, PreparedStatement ps) throws SQLException { 
    // TODO Auto-generated method stub 
    ps.setString(1, item.getID()); 
    }  
}

我想你错过了'WHERE ID =？'在查询 –

结束即使我添加一个WHERE条件，它的行为同样 –

我想更新一列'Y'（如果该文件中存在该ID）（从文件读取器中读取）出现在此DB选项卡中乐。否则更新为'N' –
