Spring remove printout Could not load properties f

Question

I'm building a gradle plugin in which I want to give users the ability to override some properties from an external file. I'm using the Spring propertyPlaceholderConfigurer in order to set a few destinations where users can place their files, This works as expected. My problem is that when running my plugin Spring prints out to the console: "Could not load properties from URL [...]" Does anyone have any idea how I would go about squelching this message?

I've tried overriding logback and sl4j to no avail.

My Spring application-context xml:

Answer 1

If you want to implement custom logic to set locations you can extend PropertyPlaceholderConfigurer like

class CustomPropertyPlaceholderConfigurer extends org.springframework.beans.factory.config.PropertyPlaceholderConfigurer {

    public void setFileName(String fileName) throws FileNotFoundException {
        File file = findPropertyFile(fileName);  // implement property file loading
        super.setLocation(new FileSystemResource(file));
    }

and use it like

<bean id="propertyPlaceholderConfigurer" class="package.CustomPropertyPlaceholderConfigurer ">
    <property name="placeholderPrefix" value="${"/>
    <property name="ignoreResourceNotFound" value="true"/>
    <property name="systemPropertiesMode" value="2"/>
</bean>

Answer 2

As far as I understand there are no such files.

Try to add configs below to the propertyPlaceholderConfigurer

<property name="ignoreUnresolvablePlaceholders" value="true" />
<property name="ignoreResourceNotFound" value="true" />

Answer 3

I found that the message was originating in PropertiesLoaderSupport at the loadProperties method:

if (this.ignoreResourceNotFound) {
                    if (logger.isWarnEnabled()) {
                        logger.warn("Could not load properties from " + location + ": " + ex.getMessage());
                    }
                }

So what I ended up doing is set the logger level in my gradle task to Error as follows:

task.doFirst {
    logger.context.level = LogLevel.ERROR
    logging.captureStandardOutput LogLevel.ERROR
}
