Is Jasypt 1.9.2 compatible with Spring 4.3.8?

Question

We are migrating an ant based spring 3.1 app to maven based spring 4.3.8. We are encrypting our property file entries with Jasypt 1.9.2. However, when the app is started, it throws

Caused by: org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [org.jasypt.spring31.properties.EncryptablePropertyPlaceholderConfigurer] for bean with name 'propertyPlaceholderConfigurer' defined in ServletContext resource [/WEB-INF/applicationContext.xml]; nested exception is java.lang.ClassNotFoundException: org.jasypt.spring31.properties.EncryptablePropertyPlaceholderConfigurer

jasypt-1.9.2 and jasypt-spring31-1.9.2 jars are available under WEB-INF/lib folder. Below is the application context:

    </bean>
</beans> 

Maven entry is :

<dependency>
        <groupId>org.jasypt</groupId>
        <artifactId>jasypt-spring31</artifactId>
        <version>1.9.2</version>
</dependency>

Answer 1

No. According to http://jasypt.org/encrypting-configuration.html:

Spring-integrated transparent decryption of .properties files: Jasypt can integrate into the configuration system of the Spring Framework (2.x and 3.x) and transparently decrypt .properties files used by Spring applications. Learn more: Spring 2.x, Spring 3.0, Spring 3.1.
