VMware Tanzu Application Service for VMs

Issue/Introduction

One SpringBoot app was using Spring-Cloud-Services-Connector to get properties of the registry service instance binding to the application. However, the application was not able to start after being pushed to the Tanzu Application Service (TAS) for VMs platform. The error messages from application logs look similar to the following.

Environment

Product Version: 2.1

Resolution

The application was adding a bean to encrypt or decrypt JDBC properties with the jasypt.spring4 package.  
<bean class="org.jasypt.spring4.properties.EncryptablePropertyPlaceholderConfigurer">
                <constructor-arg ref="configurationEncryptor" />
                <property name="locations">
                        <list>
                           <value>classpath:config/dev/jdbc.properties</value>
                           <value>classpath:config/dev/context.properties</value>
                        </list>
                </property>
 </bean>

However, jasypt.spring4 package is not compatible with SpringBoot, which would break functionality of RandomValuePropertySource class to resolve place holder, like  ${random.value}.

It is required to use the jasypt-spring-boot package instead for SpringBoot applications to encrypt or decrypt sensitive data.
