private int custNo;
private String custName;
private          


        

Answer 1

I used the liquibase-hibernate plugin for this!. It is capable of generating the changeset for a JPA entity even if its corresponding table is not there in the db.

The plugin

<plugins>
    <plugin>
        <groupId>org.liquibase</groupId>
        <artifactId>liquibase-maven-plugin</artifactId>
        <version>3.4.1</version>
        <configuration>                  
            <propertyFile>src/main/resources/liquibase.properties</propertyFile>
        </configuration> 
        <dependencies>
            <dependency>
                <groupId>org.liquibase.ext</groupId>
                <artifactId>liquibase-hibernate4</artifactId>
                <version>3.5</version>
            </dependency>
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-beans</artifactId>
                <version>4.1.7.RELEASE</version>
            </dependency>
            <dependency>
                <groupId>org.springframework.data</groupId>
                <artifactId>spring-data-jpa</artifactId>
                <version>1.7.3.RELEASE</version>
            </dependency>
        </dependencies>               
    </plugin> 
</plugins>

and the liquibase.properties

changeLogFile=classpath:liquibase-changeLog.xml
url=jdbc:mysql://localhost:3306/oauth_reddit
username=tutorialuser
password=tutorialmy5ql
driver=com.mysql.jdbc.Driver
referenceUrl=hibernate:spring:org.baeldung.persistence.model
  ?dialect=org.hibernate.dialect.MySQLDialect
diffChangeLogFile=src/main/resources/liquibase-diff-changeLog.xml

The referenceUrl is using package scan, so the dialect parameter is required. changeLogFile is the location of changeset for which the db is in sync. diffChangeLogFile is the location where the difference changelog has to be flushed.
