java – 读取CSV中的换行符,它在Spring批处理的FlatfileItemReader中的文件中引用

我试图用FlatFileItemReader解析CSV文件.此CSV包含一些引用的换行符,如下所示.

email,name
[e-mail],"NEW NAME
 ABC"

但是这个解析失败了,必填字段为2但实际为1.

我在FlatFileReader配置中缺少什么？

<property name="lineMapper">
            <bean class="org.springframework.batch.item.file.mapping.DefaultLineMapper">

                <!-- The linetokenizer divides individual lines up into units of work -->
                <property name="linetokenizer">
                    <bean
                        class="org.springframework.batch.item.file.transform.DelimitedLinetokenizer">

                        <!-- Names of the CSV columns -->
                        <property name="names"
                            value="email,name" />
                    </bean>
                </property>

                <!-- The fieldSetMapper maps a line in the file to a Product object -->
                <property name="fieldSetMapper">
                    <bean
                        class="com.abc.testme.batchjobs.util.CustomerFieldSetMapper" />
                </property>
            </bean>
        </property>

解决方法

开箱即用的FlatFileItemReader使用 SimpleRecordSeparatorPolicy作为您的用例

>评论部分超过2行或更多行

你需要设置DefaultRecordSeparatorPolicy

引用它的javadoc：

A RecordSeparatorPolicy that treats all lines as record endings,as
long as they do not have unterminated quotes,and do not end in a
continuation marker.

示例xml配置

<bean id="reader" 
      class="org.springframework.batch.item.file.FlatFileItemReader">
      ...
    <property name="recordSeparatorPolicy">
        <bean class="org.springframework.batch.item.file.separator.DefaultRecordSeparatorPolicy" />
    </property>
      ...
</bean>
