Entity not in database - Spring-Data-Jpa + Postgres

Question

I have been having issues with my Hibernate attempting to persist and find instances from the database. After investigating, it was suggested that dropping the table and rerunning the application might help. After executing the command drop table users; in the database, my spring application will not recreate the entity onto the schema. I have tried changing the dll-auto property but nothing happens. I am using the spring-boot-starter-data-jpa dependency and not a hibernate.cfg.xml file. Furthermore, after persisting a User to the db (when there is a users table), the EntityManager.find() method returns null despite the fact that there is a row for a user.

application.properties: 

spring.jpa.hibernate.ddl-auto=create
spring.jpa.generate-ddl=true
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://ec2-54-243-187-30.compute-1.amazonaws.com:5432/dbte05lnlcfhd2?user=gmjgnsqxmifijr&password=cc713437b57783d84638d0a3a91bcecd62527cbef98c7b4c25188113dc8c5147&sslmode=require

}

EDIT

First issue resolved by running mvn clean install -DskipTests .

The second issue still remains, running the getUser() method in UserRepository.java through a REST api returns null.

Change your properties to this : 

# Disable feature detection by this undocumented parameter. Check the org.hibernate.engine.jdbc.internal.JdbcServiceImpl.configure method for more details.
spring.jpa.properties.hibernate.temp.use_jdbc_metadata_defaults = false

# Because detection is disabled you have to set correct dialect by hand.
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQL9Dialect
