Liquibase and spring jpa - spring

Question

I'm having problem with deploy postgres on a linux environment though I don't sure it's related.
Linux version: 9.3.11
Windows version: 9.5
The error that I get:
2016-03-15_19:19:40.478 [http-nio-9090-exec-3] WARN o.h.e.jdbc.spi.SqlExceptionHelper - SQL Error: 0, SQLState: 42P01
2016-03-15_19:19:40.479 [http-nio-9090-exec-3] ERROR o.h.e.jdbc.spi.SqlExceptionHelper - ERROR: relation "rbac_roles" does not exist
Position: 125
2016-03-15_19:19:40.520 [http-nio-9090-exec-3] ERROR o.a.c.c.C.[.[.[.[dispatcherServlet] - Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.dao.InvalidDataAccessResourceUsageException: could not extract ResultSet; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet] with root cause
org.postgresql.util.PSQLException: ERROR: relation "rbac_roles" does not exist
Position: 125
On my windows environment table definition created by Liquibase looks as following:
-- Table: public.rbac_roles
-- DROP TABLE public.rbac_roles;
CREATE TABLE public.rbac_roles
(
tenantid character varying(255) NOT NULL,
id integer NOT NULL DEFAULT nextval('rbac_roles_id_seq'::regclass),
name character varying(255) NOT NULL,
urlprefix character varying(255),
CONSTRAINT pk_rbac_roles PRIMARY KEY (id),
)
WITH (
OIDS=FALSE
);
ALTER TABLE public.rbac_roles
OWNER TO postgres;
On my linux (the prblematic) environment table definition created by Liquibase looks as following:
-- Table: public.rbac_roles
-- DROP TABLE public.rbac_roles;
CREATE TABLE public.rbac_roles
(
tenantid character varying(255) NOT NULL,
id serial NOT NULL,
name character varying(255) NOT NULL,
urlprefix character varying(255),
CONSTRAINT pk_rbac_roles PRIMARY KEY (id),
)
WITH (
OIDS=FALSE
);
ALTER TABLE public.rbac_roles
OWNER TO postgres;
The Spring Jpa object looks like this:
#Entity(name = "rbac_roles")
public class Role implements HasTenantId {
#Id
#SequenceGenerator(name="roles_seq", sequenceName = "rbac_roles_id_seq")
#GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "roles_seq")
private int id;
...
The Liquibase config looks like this:
<createTable tableName="rbac_roles">
<column name="tenantid" type="varchar(255)">
<constraints primaryKeyName="pk_roles" nullable="false" />
</column>
<column name="id" autoIncrement="true" type="integer">
<constraints primaryKey="true" nullable="false" />
</column>
...
</createTable>
The table rbac_roles created successfully but ID looks diffrent
What I'm doing wrong, why the behavior is different?

Answer 1

In your JPA Annotations you are using a sequence generator, but in your changelog there is an autoincrement type for ID attribute
<createTable tableName="rbac_roles">
<column name="tenantid" type="varchar(255)">
<constraints primaryKeyName="pk_roles" nullable="false" />
</column>
<!-- HERE you specify autoincrement -->
<column name="id" autoIncrement="true" type="integer">
<constraints primaryKey="true" nullable="false" />
</column>
...
</createTable>
It is confusing, and I don't know why this code is generating different tables on windows and linux, maybe your postgresql is not the same version ...
Please, fix your changelog and put the following
<createTable tableName="rbac_roles">
<column name="tenantid" type="varchar(255)">
<constraints primaryKeyName="pk_roles" nullable="false" />
</column>
<!-- Removed autoincrement -->
<column name="id" type="integer">
<constraints primaryKey="true" nullable="false" />
</column>
...
</createTable>
<!-- HERE I specify sequence -->
<createSequence sequenceName="rbac_roles_id_seq" incrementBy="1"/>
This way, it should generate same table on both systems.
