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

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.

Any idea?

For generating incremental diff, we need to run task liquibaseUpdate first before liquibaseDiffChangelog
Added the below extension
task generateLiquibaseChangelog {
dependsOn 'clean'
dependsOn 'liquibaseUpdate'
dependsOn 'liquibaseDiffChangeLog'
tasks.findByName('liquibaseUpdate').mustRunAfter 'clean'
tasks.findByName('liquibaseDiffChangeLog').mustRunAfter 'liquibaseUpdate'

project.ext."liquibaseTimestamp"=getTimestamp()
}
def getTimestamp() {
return new Date().format('yyyyMdHHms')

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

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:

I think I am not able to override method toPhysicalTableName properly, please let me know what is wrong I did.
Help is highly appreciated. thanks in advance.

How to create a pool of bean in spring?

In my project , i need to call some other app SOAP url to get connection , on top of that connection obj, i need to pass various request to get response. This response i need to parse to get actual results data.
There is an API called Retrival class object when holds the connection. Need to use the same for connection i.e. pass requests and get response object.
So I can declase it as prototype scope to get these Retrival objects.
But I am using Akka Actors which fetch different data using these objects.
I cant create unknownnumber of bean of Retrival class using prototype scope. Which may later result in OOM exception.
I want to create some says 20 beans of Retrival class and use them.
How can i do it in spring, i am using spring latest version.
I tried to use commonspool2targetsource but as by Retrival class imported from other application jar... which is not recognizing Retrival.class in the class path.
Not sure how to go about it , any help is highly appreciated.
Here is the piece of sample code what i am doing:
#Bean(name="retriver")
#Scope("prototype")
public Retriver retriver() {
Retriver dr = null;
try {
dr = new Retriver(config.getUserName(),
config.getPassword(),
config.getUrl());
} catch (Exception e) {
logger.error("Exepction in creating SOAP datasource connection");
}
return dr;
}
#Bean
public CommonsPool2TargetSource RetriverPooledTargetSource() {
final CommonsPool2TargetSource commonsPoolTargetSource = new CommonsPool2TargetSource();
commonsPoolTargetSource.setTargetBeanName("Retriver");
commonsPoolTargetSource.setTargetClass(Retriver.class); //Getting error here....
commonsPoolTargetSource.setMaxSize(10);
return commonsPoolTargetSource;
}
#Bean
public ProxyFactoryBean proxyFactoryBean() {
ProxyFactoryBean p = new ProxyFactoryBean();
p.setTargetSource(RetriverPooledTargetSource());
return p;
}
Error : The type org.apache.commons.pool2.PooledObjectFactory cannot be resolved. It is indirectly referenced from required .class files
Part-2 Question:
Changing to below common-pool2 ..earlier error disappeared.
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-pool2</artifactId>
</dependency>
But when I say pool.getActive as below is displaying count as 0
CommonsPool2TargetSource pool = configurationUtils.retrieverPooledTargetSource();
System.out.println( " pool.getActiveCount " + pool.getActiveCount());
There is no exception as such but when i checked the pool object above.
There is a filed called creationException
Which reads as below :
java.lang.Exception

You need to add the following dependency (this is for maven build):
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-pool2</artifactId>
</dependency>

Add this property in your application.properties :
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true
Reference :
https://github.com/spring-projects/spring-boot/issues/12007#issuecomment-369388646

This is an issue of Hibernate, as a workaround, you can use the following flag. Then set up the following config in your properties:
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true
For Spring boot 2.x.x this flag simply disable contextual LOB creation, but if you really want to know the properly answer check UPDATE V1.
UPDATED V1
This was a Hibernate issue.
If you use Spring Boot latest version from 2.0.x until 2.1.x
includes Hibernate 5.3.10.final you can take a look here but this issue was fixed on Hibernate version 5.4.0.CR1 then you need to add that dependency or if it is possible the latest version:
For Gradle:
compile('org.hibernate:hibernate-core:5.4.2.Final')
For Maven:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.4.2.Final</version>
</dependency>
UPDATED V2 "SPRING BOOT 2.2.0.M(1-4)"
In addition Spring boot v2.2.0.Mx includes now Hibernate v5.4.x then this issue was fixed for these versions.

I had the similar issue.
I followed this solution and it worked for me
http://vkuzel.blogspot.com/2016/03/spring-boot-jpa-hibernate-atomikos.html
# 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

Solved by using following Yaml configuration:
spring:
jpa:
properties:
hibernate:
jdbc:
lob:
non_contextual_creation: true
database-platform: org.hibernate.dialect.PostgreSQL9Dialect

Solved by adding hibernate.properties with
hibernate.jdbc.lob.non_contextual_creation=true
Other solutions with application.properties didn't work. This can be also done via XML hibernate.cfg.xml
Spring Boot version: 2.0.2.RELEASE

spring:
jpa:
properties:
hibernate:
temp:
use_jdbc_metadata_defaults: false
jdbc:
lob:
non_contextual_creation: true
with
use_jdbc_metadata_defaults: false
or
non_contextual_creation: true
two items work fine

Faced the same problem with Spring Boot version: 2.1.x.RELEASE too.
it worked with:
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true

I was struggling with this stuff for a day.
Spring boot version 2.2.5
Postgres: 42.2.10
Version of Postgres on server: PostgreSQL 11.6 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 4.9.3, 64-bit
I was using Spring JPA data with Hibernate configuration. Using sessionFactory.
Hibernate configuration:
#Bean(name = "sessionFactory")
#Primary
public LocalSessionFactoryBean sessionFactory(){
LocalSessionFactoryBean sessionFactoryBean = new LocalSessionFactoryBean();
sessionFactoryBean.setDataSource(assetHealthDataSource);
sessionFactoryBean.setMappingDirectoryLocations(new Resource[]{new ClassPathResource("mappings")});
sessionFactoryBean.setHibernateProperties(hibernateProperties());
return sessionFactoryBean;
}
Hibernate Properties:
private final Properties hibernateProperties() {
Properties hibernateProperties = new Properties();
hibernateProperties.setProperty(
"hibernate.dialect", "org.hibernate.dialect.PostgreSQL9Dialect");
hibernateProperties.setProperty(
"hibernate.jdbc.lob.non_contextual_creation", "true");
hibernateProperties.setProperty(
"hibernate.temp.use_jdbc_metadata_defaults", "false");
hibernateProperties.setProperty(
"hibernate.show_sql", environment.getProperty("assetHealthDataSource.hibernate.showSQL"));
hibernateProperties.setProperty(
"hibernate.format_sql", environment.getProperty("assetHealthDataSource.hibernate.formatSQL"));
hibernateProperties.setProperty(
"hibernate.transaction.auto_close_session", "false");
hibernateProperties.setProperty(
"hibernate.hibernate.connection.release_mode", "auto");
hibernateProperties.setProperty(
"hibernate.hikari.maximumPoolSize", "3");
hibernateProperties.setProperty(
"hibernate.default_schema", "MY_SCHEMA");
return hibernateProperties;
}
But everything was not working properly. Willing to see any suggestion that can help to solve this out.
Thank you very much.

For anyone searching for a Grails answer (3.3 and up), #Ashutosh's answer worked for me but what caught me out is in your application.yml file, you omit the spring.jpa.properties prefix. Add it to the hibernate section, where you're likely to have your dialect specified:
hibernate:
dialect: <your dialect>
jdbc:
lob:
non_contextual_creation: true
temp:
use_jdbc_metadata_defaults: false

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.
