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.JdbcTemplate
import 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)
@EnableTransactionManagement
class 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 8
a quick note on
Delayed again! from 09/2013 to as late as 03/2014!
Meanwhile, even has lambas...
...
C++

Java 8
a 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 8
a 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 interface
Customer customer = jdbcTemplate.queryForObject(
"select name, age from customers ",
this::map);

Java 8
a quick note on
lambas are a great fit for Spring!
JdbcTemplate jdbc;
Customer customer = jdbc.queryForObject(sql,
(rs, rowNum) -> new Customer(rs.getLong("id")));

Java 8
a quick note on
lambas are a great fit for Spring and Twitter!

Java 8
a 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 8
a quick note on
Repeatable Annotations
@Scheduled(cron = "0 0 12 * * ?")
@Scheduled(cron = "0 0 18 * * ?")
public void performTempFileCleanup() {
...
}

Java 8
a 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 environments
Supports 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)
