java - Spring Batch property placeholder endline -

i facing problem while trying store end line separator in java properties file in order import xml configuration file.

with 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 = 
 

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 it's working quotes remains.
