Class SpringJmsMatsFactoryProducer

java.lang.Object

io.mats3.spring.jms.factories.SpringJmsMatsFactoryProducer

public class SpringJmsMatsFactoryProducer
extends java.lang.Object

Provides an easy way to get hold of the most probable JmsMatsFactory transaction manager configuration in the Spring world (using JmsMatsTransactionManager_JmsAndSpringManagedSqlTx, or only the JmsMatsTransactionManager_Jms if no DataSource is needed). You may either supply a DataSource, or a Spring PlatformTransactionManager (typically DataSourceTransactionManager or HibernateTransactionManager). The code here is very simple, really just creating the MatsFactory normally and then wrapping it up in a SpringJmsMatsFactoryWrapper which provides hook-in to the Spring context (read more about those hook-in features on its JavaDoc).

NOTE: It returns an instance of SpringJmsMatsFactoryWrapper, which it is assumed that you put in the Spring context as a bean, so that Spring property injection and @PostConstruct is run on it. If you instead employ a FactoryBean (e.g. because you have made a cool Mats single-annotation-configuration solution for your multiple codebases), then you need to invoke SpringJmsMatsFactoryWrapper.postConstructForFactoryBean(Environment, ApplicationContext) - read up!

static SpringJmsMatsFactoryWrapper	createJmsTxOnlyMatsFactory(java.lang.String appName, java.lang.String appVersion, MatsSerializer<?> matsSerializer, javax.jms.ConnectionFactory jmsConnectionFactory) If you need a MatsFactory that only handles the JMS transactions, this is your factory method - but if you DO make any database calls within any Mats endpoint lambda, you will now have no or poor transactional demarcation, use createSpringDataSourceTxMatsFactory(..) instead.

createSpringDataSourceTxMatsFactory

public static SpringJmsMatsFactoryWrapper createSpringDataSourceTxMatsFactory(java.lang.String appName,
                                                                              java.lang.String appVersion,
                                                                              MatsSerializer<?> matsSerializer,
                                                                              javax.jms.ConnectionFactory jmsConnectionFactory,
                                                                              javax.sql.DataSource sqlDataSource)

If you need a MatsFactory employing Spring's DataSourceTransactionManager (which you probably do in a Spring environment utilizing SQL), this is your factory method.

Usage: Make a @Bean-annotated method which returns the result of this method, or employ a Spring FactoryBean where you then need to invoke SpringJmsMatsFactoryWrapper.postConstructForFactoryBean(Environment, ApplicationContext).

Parameters:

appName - the containing application's name (for debugging purposes, you'll find it in the trace).

appVersion - the containing application's version (for debugging purposes, you'll find it in the trace).

matsSerializer - the JmsMatsFactory utilizes the MatsSerializer, so you need to provide one. (It is probably the one from the 'mats-serial-json' package).

jmsConnectionFactory - the JMS ConnectionFactory to fetch JMS Connections from, using ConnectionFactory.createConnection(). It is assumed that if username and password is needed, you have configured that on the ConnectionFactory.

sqlDataSource - the SQL DataSource which to stash into a Spring DataSourceTransactionManager, and from which SQL Connections are fetched from, using DataSource.getConnection(). It is assumed that if username and password is needed, you have configured that on the DataSource.

Returns:

the produced SpringJmsMatsFactoryWrapper

createSpringPlatformTransactionManagerTxMatsFactory

public static SpringJmsMatsFactoryWrapper createSpringPlatformTransactionManagerTxMatsFactory(java.lang.String appName,
                                                                                              java.lang.String appVersion,
                                                                                              MatsSerializer<?> matsSerializer,
                                                                                              javax.jms.ConnectionFactory jmsConnectionFactory,
                                                                                              org.springframework.transaction.PlatformTransactionManager platformTransactionManager)

If you need a MatsFactory employing a PlatformTransactionManager of your choosing, which you quite possibly want in a Spring environment using e.g. Spring JDBC or Hibernate, this is your factory method.

Usage: Make a @Bean-annotated method which returns the result of this method, or employ a Spring FactoryBean where you then need to invoke SpringJmsMatsFactoryWrapper.postConstructForFactoryBean(Environment, ApplicationContext).

Parameters:

appName - the containing application's name (for debugging purposes, you'll find it in the trace).

appVersion - the containing application's version (for debugging purposes, you'll find it in the trace).

matsSerializer - the JmsMatsFactory utilizes the MatsSerializer, so you need to provide one. (It is probably the one from the 'mats-serial-json' package).

platformTransactionManager - the PlatformTransactionManager (typically DataSourceTransactionManager or HibernateTransactionManager) that the MatsFactory should employ.

Returns:

the produced SpringJmsMatsFactoryWrapper
