File based h2 persisted but not loaded in Spring Boot

I made a small application based on Spring Boot: - spring-boot-starter-web - spring-boot-starter-data-jpa The application has simply one domain class `Post.java`. Accordingly there is a RestController and a DAO. The data is supposed to be persisted in a file based hsql db. When the application is running everything seems fine. Data is stored. The h2 file is created and contains insert statements. However, when I kill the application and start it a second time. No data is loaded. (As if a brand new db file was created, which overwrote the old one). application.properties ``` spring.datasource.url = jdbc:h2:file:~/testdb spring.datasource.username = sa spring.datasource.password = sa spring.datasource.driverClassName = org.h2.Driver ``` pom.xml ``` <!-- Spring Boot Web --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!-- Spring Boot Data JPA --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> </dependency> <!-- H2 DB --> <dependency> <groupId>com.h2database</groupId> <artifactId>h2</artifactId> <version>1.4.179</version> </dependency> ``` PostDAO.java ``` public interface PostDAO extends JpaRepository<Post, Integer>{ public Post findByMessage(String message); } ``` Post.java ``` @Entity public class Post { @Id @GeneratedValue(strategy=GenerationType.IDENTITY) private Long id; private String message; public Post(){ } public Post(String message) { super(); this.message = message; } public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getMessage() { return message; } public void setMessage(String message) { this.message = message; } } ```
