春季批次2.1.9 - 分隔符错误

Question

我正在使用 spring batch 2.1.9(在类路径 spring-batch-core-2.2.1.RELEASE.jar 和 spring-batch-infrastructure-2.1.9.RELEASE.jar 中有两个 jar)

我有一个CSV文件作为输入，我想将数据存储在数据库中并获得4个文件作为输出。

我的输入文件中的分隔符是 ;

第一个插入作业正确启动，数据插入数据库。

在这里没关系。第二个作业我采用相同的文件，其数据入到数据库中，具有相同的分隔符。

但是当我运行我的进程时，我立即收到错误异常：

Answer 1

据我所知，当您为"exampleFileSourceReader"定义行标记器时，您没有设置分隔符。默认情况下，它是一个逗号，但您的文件包含";"。

"flatFileItemReader"的定义是正确的，并且包含分隔符。因此，这个正在起作用。

<bean id="exampleFileSourceReader" class="org.springframework.batch.item.file.FlatFileItemReader" scope="step">
<property name="resource" value="file:#{jobParameters['file']}" />
<property name="lineMapper">
<bean class="org.springframework.batch.item.file.mapping.DefaultLineMapper">
<!-- split it -->
<property name="lineTokenizer">
<bean class="org.springframework.batch.item.file.transform.DelimitedLineTokenizer">
<!-- this is missing --> 
<property name="delimiter" value";"/>

<property name="names" value="institution,type,nom,rubrique,montantPaye,MontantRetenu" />
</bean>
</property>
<property name="fieldSetMapper">
<!-- map to an object -->
<bean class="org.springframework.batch.item.file.mapping.BeanWrapperFieldSetMapper">
<property name="prototypeBeanName" value="exampleFileMapper" />
</bean>
</property>
</bean>
</property>
