Org.springframework.core.env.PropertySourcesPropertyResolver debug print value

Question

I am reading the jdbc.properties file using the placeholder properties as shown below.

<context:property-placeholder location="classpath*:jdbc.properties" />

In the properties file, I save the jdbc configuration along with the password. When I run Springframework in debug mode. It prints the property value, which is the password. Is there any solution to fix this? Here is my log statement.
