Inject file content

[ojs]

Hello,

is it possible to inject the content of a file to a setter that expects a string?

yes but you have to do somehow the translation. A property editor would work but since there is already one for String the easiest way is to use a FactoryBean:

<bean ..>
<property name="fileContent">
<bean class="ReadFileFactoryBean">
<property name="file" value="classpath:/some/classpath/to/file"/>
</bean>
</property>
</bean>

Even better, you can remove the factory bean with an exiting class and use the factory method instead:

<bean ..>
<property name="fileContent">
<bean class="MyFileReader" factory-method="getFileContent">
<constructor value="/path/to/file"/>
</bean>
</property>
</bean>

Thanks. I thought there must be something that is usable out of the box without writing a custom Factory.

If you already have a (static) method reading the file contents into a string (quite easy to implement), you can also use MethodInvokingFactoryBean to obtain the string and inject it into a property.
