SPRING IS.. GITHUB

SPRING WORKS IN MANY LANGUAGES

Spring loves the JVM: Java (5,6,7, and 8), Groovy, Scala, etc.


val applicationContext = new FunctionalConfigApplicationContext( classOf[ServiceConfiguration])

// ServiceConfiguration.scala class ServiceConfiguration extends FunctionalConfiguration { importClass(classOf[DataSourceConfiguration])

val dataSource : DataSource = getBean(“dataSource”)

val jdbcTemplate = bean() { new JdbcTemplate( dataSource ) } val jdbcTransactionManager = bean(“txManager”) { new JdbcTransactionManager(dataSource) }}

Scala


def bb = new BeanBuilder() bb.loadBeans("classpath:*SpringBeans.groovy") def applicationContext = bb.createApplicationContext()

// MySpringBeans.groovy import o.sf.jdbc.core.JdbcTemplateimport o.sf.jdbc.datasource.DataSourceTransactionManager

beans {

jdbcTemplate(JdbcTemplate) { dataSource = dataSource }

transactionManager(DataSourceTransactionManager) { dataSource = dataSource }}

Groovy


ApplicationContext applicationContext = new AnnotationConfigApplicationContext( ServiceConfiguration.class);

// ServiceConfiguration.java @Configuration@ComponentScan@Import(DataSourceConfiguration.class) @EnableTransactionManagementclass ServiceConfiguration { @Bean public JdbcTemplate jdbcTemplate(DataSource dataSource) throws Exception { return new JdbcTemplate( dataSource ); }

@Bean public PlatformTransactionManager jdbcTransactionManager(DataSource dataSource){ return new JdbcTransactionManager (dataSource ); } }

Java


Java 8a quick note on Delayed again! from 09/2013 to as late as 03/2014!

Meanwhile, even has lambas...

...C++


Java 8a quick note on IDE Support:

IntelliJ IDEA has had Java 8 support for a year Eclipse won’t have any until June 2014 (..!!) Eclipse-based Spring Tool Suite (STS) has beta Java 8 support.


Java 8a quick note on Spring 4.0 to be GA against Developer Preview by end of 2013.

Method references are a great fit for Spring!

JdbcTemplate jdbcTemplate;

// method references private Customer map(ResultSet rs, int rowNum) throws SQLException { return new Customer( rs.getString("name"), rs.getInt("age") );}

// let it satisfy the `RowMapper` functional interfaceCustomer customer = jdbcTemplate.queryForObject( "select name, age from customers ", this::map);



lambas are a great fit for Spring!

JdbcTemplate jdbc;

Customer customer = jdbc.queryForObject(sql, (rs, rowNum) -> new Customer(rs.getLong("id")));



lambas are a great fit for Spring and Twitter!


Java 8a quick note on JSR-310 - Date and Time

// declarative date format import java.time.*;import org.springframework.format.annotation.*;

public class Customer {

@DateTimeFormat(iso=ISO.DATE) private LocalDate birthDate;

@DateTimeFormat(pattern="M/d/yy h:mm") private LocalDateTime lastContact;

}


Java 8a quick note on Repeatable Annotations

@Scheduled(cron = "0 0 12 * * ?")@Scheduled(cron = "0 0 18 * * ?")public void performTempFileCleanup() { ... }


Java 8a quick note on Spring 4.0

JDK 6 -> JDK 8 Java EE 5 (with JPA 2.0 feature pack) -> Java EE 7

SPRING RUNS WELL ON JAVA EE 7

Spring works well in Java EE environmentsSupports Java EE 7: Date/Time API, JTA 1.2, JMS 2.0, JPA 2.1, Bean Validation 1.1, the new concurrency API in JSR-236, Servlet 3.1, and WebSockets (JSR 356)

Even participated in a few JSRs: the websocket JSR (356) and the Batch JSR (352)
