Java DSL for Spring Integration 1.2 Milestone 2 发布了，用于集成Spring的Java DSL。（至于什么是DSL，这个翻译成中文称作领域特定语言，具体的话请各位自行使用搜索引擎查找吧，我也爱莫能助了。）
目前迭代更新的一些亮点：
JPA support
@Autowired
private EntityManagerFactory entityManagerFactory;
@Bean
public IntegrationFlow pollingAdapterFlow() {
return IntegrationFlows
.from(Jpa.inboundAdapter(this.entityManagerFactory)
.entityClass(StudentDomain.class)
.maxResults(1)
.expectSingleResult(true),
e -> e.poller(p -> p.trigger(new OnlyOnceTrigger())))
.channel(c -> c.queue("pollingResults"))
.get();
}
@Bean
public IntegrationFlow updatingGatewayFlow() {
return f -> f
.handle(Jpa.updatingGateway(this.entityManagerFactory),
e -> e.transactional(true))
.channel(c -> c.queue("persistResults"));
}
@Bean
public IntegrationFlow retrievingGatewayFlow() {
return f -> f
.handle(Jpa.retrievingGateway(this.entityManagerFactory)
.jpaQuery("from Student s where s.id = :id")
.expectSingleResult(true)
.parameterExpression("id", "payload"))
.channel(c -> c.queue("retrieveResults"));
}Mid-flow transaction support
Scatter-Gather support
