Spring Boot: Change the attribute for #Table in Entity class - java

I have on spring boot app having one entity class which is linked to my database table also I used sequence on that table.
So I use Table annotation as well as SequenceGenerator annotation on my Entity class with hard-coded value, like this:
#Entity
#Primary
#Table(name = "tbl_name", schema = "public")
//#Table(name = "tbl_name_dev", schema = "public")
public class PoJoClass implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#SequenceGenerator(name = "tbl_name_id_seq", sequenceName = "tbl_name_id_seq", allocationSize = 1)
#GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "tbl_name_id_seq")
// PoJo attributes
// Setter/Getter
}
Which I wanted to implement in way where I can set both the table and sequence as parameter for each profile like dev and prod. As for testing we have table name different then prod in some cases.
Also, I used the same table name in my repository class with #Query annotation, which look like this:
#Query(value = "SELECT * FROM tbl_name WHERE col1 <> ?1", nativeQuery = true)
PoJoClass getLatestRecordForCompositeKey(String col1);
Finding out same way to set both as parameter on each profile base.
Update:
Alex, route me to follow this link. And I checked and tried implementing the same in my code but I might not understand that logic due to that it is failing or nothing which I did not get properly. Cloud anyone please help on this.
I wanted to use property: from my application property file and i added the same there.
As that link suggested added the Configuration class.
#Configuration
public class TableNameConfig {
#Value("${config.table.name}")
private String configTableName;
#Value("${visits.table.name}")
private String visitsTableName;
#Bean
public PhysicalNamingStrategyStandardImpl physicalNamingStrategyStandard(){
return new PhysicalNamingImpl();
}
class PhysicalNamingImpl extends PhysicalNamingStrategyStandardImpl {
#Override
public Identifier toPhysicalTableName(Identifier name, JdbcEnvironment context) {
switch (name.getText()) {
case "PoJoClass":
return new Identifier(configTableName, name.isQuoted());
case "Visits":
return new Identifier(visitsTableName, name.isQuoted());
case "Result":
default:
return super.toPhysicalTableName(name, context);
}
}
}
}
So that I can later use the property like this:
#Table(name = "${config.table.name}", schema = "public")
But I am getting this error, I think I am not able to resolve that property, not understood where to change and what:

java.lang.Integer cannot be cast to class java.lang.Long in R2DBC mysql model classes

I use R2DBC MySQL driver in my Spring Webflux reactive web. And I try to execute table schema SQL script. But the script continuously cause errors.
First, I make 3 model classes.
User.java
#Data
#AllArgsConstructor
#NoArgsConstructor
#Builder
#Table("blog_user")
public class User {
#Id
#Column("user_id")
private Long id;
#Column
private String username;
#Column
#JsonIgnore
private String password;
#Column
private String fullname;
#Column
private Integer role;
}
Post.java
#Data
#AllArgsConstructor
#NoArgsConstructor
#Builder
#Table
public class Post {
#Id
#Column("post_id")
private Long id;
#Column
private String title;
#Column
private String body;
#Column("created_date")
private LocalDateTime createdDate;
#Column("user_id")
private User user;
#Column("posts")
private Collection<Tag> tags;
}
Tag.java
#Data
#AllArgsConstructor
#NoArgsConstructor
#Builder
#Table
public class Tag {
#Id
#Column("tag_id")
private Long id;
#Column
private String body;
#Column("created_date")
private LocalDateTime createdDate;
#Column("post_id")
private Post post;
#Column("user_id")
private User user;
}
schema.sql
-- TABLE intialized.
DROP TABLE IF EXISTS tag;
DROP TABLE IF EXISTS post;
DROP TABLE IF EXISTS blog_user;
-- TABLE created.
CREATE TABLE IF NOT EXISTS blog_user (
user_id BIGINT NOT NULL,
username VARCHAR(30) NOT NULL,
password VARCHAR(255) NOT NULL,
email VARCHAR(255),
fullname VARCHAR(255),
role SMALLINT CHECK (role IN (0, 1)),
PRIMARY KEY (user_id),
UNIQUE (username)
);
CREATE TABLE IF NOT EXISTS post (
post_id BIGINT NOT NULL,
title VARCHAR(30) NOT NULL,
body TEXT,
created_date DATETIME(6) NOT NULL,
user_id BIGINT NOT NULL,
PRIMARY KEY (post_id),
FOREIGN KEY (user_id) REFERENCES blog_user (user_id)
);
CREATE TABLE IF NOT EXISTS tag(
tag_id BIGINT NOT NULL,
body VARCHAR(255),
created_date DATETIME(6) NOT NULL,
post_id BIGINT NOT NULL,
user_id BIGINT NOT NULL,
PRIMARY KEY (tag_id),
FOREIGN KEY (post_id) REFERENCES post (post_id),
FOREIGN KEY (user_id) REFERENCES blog_user (user_id)
);
Below configuration method executes schema.sql.
reactive web initializer method
#Bean
ConnectionFactoryInitializer initializer(ConnectionFactory connectionFactory) {
ConnectionFactoryInitializer initializer = new ConnectionFactoryInitializer();
initializer.setConnectionFactory(connectionFactory);
ResourceDatabasePopulator databasePopulator = new ResourceDatabasePopulator();
databasePopulator.addScripts(new ClassPathResource(schema.sql));
initializer.setDatabasePopulator(databasePopulator);
return initializer;
}
However, initially executed schema.sql throws errors,
Error starting ApplicationContext. To display the condition evaluation report re-run your application with 'debug' enabled.

I think my reactive R2DBC model classes contains some errors. ClassCastException. But I have no idea what element has wrong class type. The printed error message show no code line number. I changed the id type of model class(User, Post, Tag) into Integer type, but the same errors are thrown.
If you are using https://github.com/mirromutth/r2dbc-mysql 0.8.x RELEASE and the latest Spring Boot 2.7 or Spring Boot 3.0.x, I think there is a compatibility issue between the R2dbc MySQL driver you are using and R2dbc SPI managed by Spring Boot.
In the latest Spring Boot 3.0, R2dbc SPI was updated to 1.0, which introduced several incompatible APIs since 0.8(r2dbc-mysql 0.8.x RELEASE is aligned with R2dbc SPI 0.8). I have encountered similar exceptions when upgrading to R2dbc 0.9 and 1.0 but used driver version is incompatible.
Try to use the latest MariaDB R2dbc Driver to connect your MySQL
Consider other database, eg. PostgreSQL or switch to MariaDB directly.
Helped for me change dependency from
implementation("org.postgresql:r2dbc-postgresql:1.0.0.RELEASE")
to
implementation("io.r2dbc:r2dbc-postgresql:0.8.13.RELEASE")
for springboot 2.7.6

Hibernate Envers: org.hibernate.tool.schema.spi.SchemaManagementException: Schema-validation: wrong column type encountered in audit table

I recently upgraded my Spring Boot version from v2.2.4.RELEASE to v2.2.6.RELEASE, thereby upgrading the Hibernate and Hibernate Envers version from 5.4.10.Final to 5.4.12.Final.
The exception
When I start the application now, I get an exception from the schema validation as shown below:

The DDL statements
Apparently, Hibernate expects a column type in the aud table different than the column type from the original table. I created the tables as follows (other columns left out for brevity):
create table users
(
password binary(60) not null,
) engine = InnoDB;
create table users_aud
(
id bigint not null,
rev integer not null,
revtype tinyint,
revend integer,
password binary(60),
password_mod bit,
primary key (id, rev)
) engine = InnoDB;
The Entity in Java
The User entity in Java (other fields and equals/hashCode left out for brevity):
#Entity
#Audited
#Inheritance(strategy = InheritanceType.JOINED)
#NoArgsConstructor
#Getter
#Table(name = "users")
public abstract class User extends HasId implements UserDetails {
#Column(columnDefinition = "BINARY(60)", nullable = false)
private String password;
}
The Hibernate config
My Hibernate config looks as follows (application.yml for Spring Boot):
spring:
jpa:
hibernate:
ddl-auto: validate
properties:
hibernate:
connection:
provider_disables_autocommit: true
dialect: org.hibernate.dialect.MySQL57Dialect
implicit_naming_strategy: component-path
jdbc:
time_zone: UTC
order_inserts: true
order_updates: true
org:
hibernate:
envers:
audit_strategy: org.hibernate.envers.strategy.ValidityAuditStrategy
global_with_modified_flag: true
Final notes
The strange thing is that it worked perfectly until the version upgrade. Unfortunately, I can't find anything related to this issue in the 5.4.11 or 5.4.12 release notes except for maybe this one. The database is MySQL version 5.7.

How to lazy initialize spring-boot datasource?spring.data

I have a spring-boot application that defines a mysql DataSource:
spring.datasource.url=...
spring.datasource.username=...
spring.datasource.password=...
I run the tool as command line application triggered by a cronjob. And in 80% of all runs, I could exit the tool without having to contact the database at all:
#Controller
public class MainController {
#Autowired
private MyService myService;
public void evaluate() {
if (condition == true) myService.run();
else System.exit(0);
}
}
#Service
#Lazy
public class MyService {
#Autowired
private JdbcTemplate jdbc;
public void run() {
jdbc.execute(sql);
}
}
Problem: I want to prevent spring initializing the database at all. So, if for example the database is down or the host is unreachable (could be tested with using spring.datasource.url=localhostX), then the tool should still be runable.
Is that possible to delay the datasource initialization until it is really needed?

#SpringBootApplication(exclude = HibernateJpaAutoConfiguration.class)
Somehow the hikari pool and hibernate seem to interact on startup. And if the datasource is not present, startup fails.
Using the exclusion above with #Lazy annotation delays the initialization as expected.
But that only works because I don't make use of hibernate.
As said in spring doc(https://docs.spring.io/spring-boot/docs/2.1.13.RELEASE/reference/html/boot-features-sql.html):
Spring Data JPA repositories support three different modes of bootstrapping: default, deferred, and lazy. To enable deferred or lazy bootstrapping, set the spring.data.jpa.repositories.bootstrap-mode to deferred or lazy respectively.
So try the following config in your application.properties (or yaml):
spring.data.jpa.repositories.bootstrap-mode=lazy
Starting with Springboot 2.2 it is possible.
Add the following property in application.properties
spring.main.lazy-initialization=true
Read more detail here.
When using Hibernate as JPA implementation, I was able to avoid connecting to database during application startup by setting these 2 hibernate specific properties even though the beans are initialised at startup -
spring:
jpa:
properties:
hibernate:
temp:
use_jdbc_metadata_defaults: false
hbm2ddl:
auto: none
Here are the significance of these properties from Hibernate Documentation
hibernate.temp.use_jdbc_metadata_defaults (e.g. true (default value)
or false)
This setting is used to control whether we should consult
the JDBC metadata to determine certain Settings default values when
the database may not be available (mainly in tools usage).
and here
hibernate.hbm2ddl.auto (e.g. none (default value), create-only, drop,
create, create-drop, validate, and update)
Setting to perform
SchemaManagementTool actions automatically as part of the
SessionFactory lifecycle. Valid options are defined by the
externalHbm2ddlName value of the Action enum:
none No action will be performed.
So, after setting the properties, the jdbc connection is made only when executing sql queries.

Spring boot - just one entity cannot be created in data base

I have been using H2 as the database in my app, which is dropping all the data when app is terminated. Now I would like to use database, which persist all the data to files on my disk.
I have chosen MariaDB for this, but MariaDB can't create one of my tables (every entity gets created except one). Since I had no problems using H2 I assume it is something with my configuration.

You have a field named when which is probably causing a syntax error when it's trying to create the table. Either rename that field or use the #Column annotation to specify a column name that is allowed.
For future readers, in my case, there were no exceptions to figure it out. The issue comes from columnDefinition attribute below :
#Column(name="service_id", columnDefinition="NULL", length = 11)
private Integer serviceId;
I had to get rid of columnDefinition="NULL" as long as this attribute overrides the DDL definition and produced in my case a wrong column definition : service_id NULL (as it removes the data type definition (int)) in table's DDL generated creation code.

Configure HikariCP in Spring Boot with JTDS

I want to add a connection pool to my existing web application, which has been made using Spring Boot 1.5.1.
The datasource configuration is made in application.properties as follows:
spring.datasource.url=jdbc:jtds:sqlserver://localhost:1433;databaseName=MyDatabase;instance=SQLServer2014;
spring.datasource.username=myuser
spring.datasource.password=passwd
spring.datasource.driver-class-name=net.sourceforge.jtds.jdbc.Driver
spring.jpa.hibernate.ddl-auto=update
I don't need to make any further configuration, with this is enough.
It isn't clear enough in the official docs, although parameters are shown, nor in the Spring Boot docs.
So, I've been looking for solutions over there (this one, this one too...).
I've made several trials, but everytime I run the app, exceptions regarding HikariCP are thrown.
When adding spring.datasource.type=com.zaxxer.hikari.HikariDataSource, the following exception is thrown:

So, which is the simplest way to add hikaricp to my application.properties?
You are getting below error.
Caused by: java.lang.AbstractMethodError: null at net.sourceforge.jtds.jdbc.JtdsConnection.isValid(JtdsConnection.java:2833)
Issue is that net.sourceforge.jtds.jdbc.JtdsConnection doesn't implement isValid so you need to specify a connection-test-query to ensure that isValid method isn't called. Try by adding below property in your application.properties file.
spring.datasource.hikari.connection-test-query=SELECT 1
For using multiple datasources (Spring Boot 2.0), I had to do the following to get this to work (setting spring.datasource.hikari.connection-test-query property only worked when using a single datasource):
#Configuration
public class DataConfig {
#Bean
#Primary
#ConfigurationProperties(prefix="spring.datasource")
public DataSource primaryDataSource() {
HikariDataSource ds = (HikariDataSource) DataSourceBuilder.create().build();
ds.setConnectionTestQuery("SELECT 1");
return ds;
}
#Bean(name="secondDataSource")
#ConfigurationProperties(prefix="spring.datasource.second")
public DataSource secondDataSource() {
HikariDataSource ds = (HikariDataSource) DataSourceBuilder.create().build();
ds.setConnectionTestQuery("SELECT 1");
return ds;
}
#Bean(name="primaryJdbcTemplate")
public JdbcTemplate primaryJdbcTemplate(DataSource primaryDataSource) {
return new JdbcTemplate(primaryDataSource);
}
#Bean(name="secondJdbcTemplate")
public JdbcTemplate secondJdbcTemplate(#Qualifier("secondDataSource") DataSource secondDataSource) {
return new JdbcTemplate(secondDataSource);
}
}
I ran into the same problem and found the solution from this discussion.
It looks like, before doing any further configurations Hikari CP tests the validity of the connection by executing a test query which is missing in this case.
So as suggested by the earlier answer, you should add one test query in your application.properties file.
If you are using Oracle or mySql then you can use the following query instead (as SELECT 1 doesn't work here):
spring.datasource.hikari.connection-test-query=SELECT 1 FROM DUAL
Note: DUAL is a special one-row and one-column table present in Oracle and other databases. Thus it can be readily used to execute a simple test-query.
