Spring Batch - unable persist reader type

after upgrading to Spring Batch 3.0.2 faced the following issue: chunk step fails trying to persist reader object which is not JPA Entity and not Serializable.
#Autowired
protected PlatformTransactionManager transactionManager;
#Autowired
protected JobRepository jobRepository;
[...]
#Bean
#JobScope
public Step processFileStep() {
return new StepBuilder("process-file", jobRepository)
.<Row, Matching>chunk(chunkSize, transactionManager)
.reader(reader())
.processor()
.writer(writer())
.build();
}
Row type here is org.apache.poi.ss.usermodel.Row which is passed by custom Apache POI Excel item reader. transactionManager and jobRepository are autoconfigured by Spring Data JPA.
On this step the following exception occurs:
java.lang.IllegalArgumentException: Not an entity [class org.apache.poi.xssf.usermodel.XSSFRow]

Before this updage from Spring Batch 2.6.6 to Spring Batch 3.0.2 chunk() method did not have transactionManager parameter and this code worked as intended.
It seems like Map-based job repository should work in this case but it's not a production-ready solution.
Is there any way to use org.apache.poi.ss.usermodel.Row (or any other non-JPA object) as reader output with newer Spring Batch version with persistent storage?
Thanks in advance.

By debugging Spring Batch source code found that JpaItemWriter tries to persist list of Row's instead of Matching ones.
Found a silly mistake in my code:
#Bean
#JobScope
public Step processFileStep() {
return new StepBuilder("process-file", jobRepository)
.<Row, Matching>chunk(chunkSize, transactionManager)
.reader(reader())
.processor()
.writer(writer())
.build();
}
this part is missing an actual processor.
So my POI list of Row's passed directly to JPA writer. I've made my processor dummy for testing purposes and never checked that it was actually called.
Correct Step code is
#Bean
#JobScope
public Step processFileStep() {
return new StepBuilder("process-file", jobRepository)
.<Row, Matching>chunk(chunkSize, transactionManager)
.reader(reader())
.processor(processor())
.writer(writer())
.build();
}
Can't believe it couldn't find this issue for at least a few days.

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 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.

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.

Spring boot +Spring data JPA +Second-level cache giving mutate error

I am having an application with mutiple datasource using Spring Boot and Spring data JPA.

UPDATE ERROR
I am still not able to move fully forward, but I am getting the below error now.

I corrected the properties setting, by removing the properties bit. It was a typo. But now I am getting the above error.

The error net.spy.memcached.OperationTimeoutException: Mutate operation timed out appears to completely refer to memcached client/server interaction. Most likely the memcached server is not available on localhost:11211.

Can you try the below factory class:
net.sf.ehcache.hibernate.EhCacheRegionFactory
or
org.hibernate.cache.ehcache.Si­ngletonEhCacheRegionFactory
Also, to debug - I would probably go ahead and check the actual jars and look for the presence of the factory class in that jar.
