Spring Batch property placeholder endline

Question

I am facing a problem while trying to store an end line separator in a java properties file in order to import it into an xml configuration file.

With the following xml :

<bean id="fooWriter" class="org.springframework.batch.item.file.FlatFileItemWriter">
    <property name="resource" value="file:${myJob.file.output}" />
    <property name="lineSeparator" value="${myJob.file.lineSeparator}" />
</bean>

The following property entry :

myJob.file.lineSeparator = &#10;

Gives : foo
bar

myJob.file.lineSeparator = \n

Gives : foobar(Nothing)

myJob.file.lineSeparator = \\n

Gives : foo\nbar

myJob.file.lineSeparator = '\n' or "\n"

Gives :

foo' or foo"
'bar or "bar

it seems like it's working but the quotes remains.

Any solution to externalize the endline separator ?

Thank for your response. Unfortunately, \\n results with \n in the file. — Charles Follet, May 09 '16 at 14:15

with using jobparameters instead of propertyplaceholder it does work with "\\n", with properties file take a look in to http://stackoverflow.com/questions/2108103/can-the-key-in-a-java-property-include-a-blank-character — Michael Pralow, May 10 '16 at 07:04

it does work for me with Spring 4 and

a properties file containing

lineSeparator=\n

spring configuration

<context:property-placeholder location="classpath:META-INF/spring/my.properties"/>

spring batch configuration (removed file path config)

<bean id="itemWriter" class="org.springframework.batch.item.file.FlatFileItemWriter" scope="step" >
    <property name="lineSeparator" value="${lineSeparator}" />
</bean>
