How do you create an XPath Splitter using Spring Integration DSL? What is the DSL equivalent of this:
<!-- Split the order into items creating a new message for each item node -->
<int-xml:xpath-splitter id="orderItemSplitter"
input-channel="orderChannel"
output-channel="orderItemsChannel">
<int-xml:xpath-expression expression="/order/items"/>
</int-xml:xpath-splitter>
The Spring Integration Java DSL doesn't have any <xpath-splitter> specific component because it is enough easy to configure via regular Java configuration:
#Bean
public AbstractMessageSplitter xpathSplitter() {
return new XPathMessageSplitter("/order/items");
}
...
#Bean
public IntegrationFlow xpathFlow() {
return IntegrationFlows.from("inputChannel")
.split(xpathSplitter())
.get();
}

This projects don't describe classic bindings in application config file, we override the StreamsBuilderFactoryBean definition like this to be able to generate the topology manually.
#Bean
public StreamsBuilderFactoryBean createSBFB(){
StreamsBuilderFactoryBean streamsBuilderFactoryBean = new StreamsBuilderFactoryBean(streamConfiguration);
streamsBuilderFactoryBean.setInfrastructureCustomizer(
new KafkaStreamsInfrastructureCustomizer() {
#Override
public void configureBuilder(StreamsBuilder builder) {
builder.stream(...) // here we append our topology
}
}
}
This is perfectly working but we are loosing healthcheck mecanism, and kafkastream actuator metrics.
Is there a way to work around ?
the main goal is to retrieve the topology from a rest service. Can we use spring cloud stream in this context ?
im developing a Project using Spring Batch and JavaConfig (no XML).
I am creating Jobs using an Autowired jobBuilderFactory.
is it somehow possible to set the Incrementer for the Factory globally ?
return jobBuilderFactory.get("jobName").incrementer(new RunIdIncrementer()).start(stepOne()).next(lastStep()).build();
sorry if this is a dump question but i am new to Spring Batch and did not find a working solution.
With XML config you would use bean definition inheritance, but you said you don't use XML.
Since there is no equivalent of XML bean definition inheritance with Java config (See details here: https://stackoverflow.com/a/23266686/5019386), you can create the RunIdIncrementer globally in your config and use it in job definitions:
public JobParametersIncrementer jobParametersIncrementer() {
return new RunIdIncrementer();
}
public JobBuilder getJobBuilder(String jobName) {
return jobBuilderFactory.get(jobName)
.incrementer(jobParametersIncrementer());
}
#Bean
public Job job1() {
return getJobBuilder("job1")
.start(step())
.build();
}
#Bean
public Job job2() {
return getJobBuilder("job2")
.start(step())
.build();
}
But again and as said in comments, you will end up having run.id values that are not consecutive for each job.
I am new to the Spring ws.For the following things i need some clarification
1.I want to know how to customise the bindings,operations,port names etc..that is generated automatially by Spring.
2.How to specify multiple bindings,port types if we have multiple operations so that all should be generated in same wsdl.
You can customize the dynamic WSDL properties using DefaultWsdl11Definition bean
#Bean
public DefaultWsdl11Definition orders() {
DefaultWsdl11Definition definition = new DefaultWsdl11Definition();
definition.setPortTypeName("Orders");
definition.setLocationUri("http://localhost:8080/ordersService/");
definition.setSchema(new SimpleXsdSchema(new ClassPathResource("echo.xsd")));
return definition;
}

I have a project and in it I'm using spring-boot-jdbc-starter and it automatically configures a DataSource for me.
Now I added camel-spring-boot to project and I was able to successfully create routes from Beans of type RouteBuilder.
But when I'm using sql component of camel it can not find datasource. Is there any simple way to add Spring configured datasource to CamelContext? In samples of camel project they use spring xml for datasource configuration but I'm looking for a way with java config. This is what I tried:
#Configuration
public class SqlRouteBuilder extends RouteBuilder {
#Bean
public SqlComponent sqlComponent(DataSource dataSource) {
SqlComponent sqlComponent = new SqlComponent();
sqlComponent.setDataSource(dataSource);
return sqlComponent;
}
#Override
public void configure() throws Exception {
from("sql:SELECT * FROM tasks WHERE STATUS NOT LIKE 'completed'")
.to("mock:sql");
}
}
I have to publish it because although the answer is in the commentary, you may not notice it, and in my case such a configuration was necessary to run the process.
The use of the SQL component should look like this:
from("timer://dbQueryTimer?period=10s")
.routeId("DATABASE_QUERY_TIMER_ROUTE")
.to("sql:SELECT * FROM event_queue?dataSource=#dataSource")
.process(xchg -> {
List<Map<String, Object>> row = xchg.getIn().getBody(List.class);
row.stream()
.map((x) -> {
EventQueue eventQueue = new EventQueue();
eventQueue.setId((Long)x.get("id"));
eventQueue.setData((String)x.get("data"));
return eventQueue;
}).collect(Collectors.toList());
})
.log(LoggingLevel.INFO,"******Database query executed - body:${body}******");
Note the use of ?dataSource=#dataSource. The dataSource name points to the DataSource object configured by Spring, it can be changed to another one and thus use different DataSource in different routes.
Here is the sample/example code (Java DSL). For this I used
Spring boot
H2 embedded Database
Camel
on startup spring-boot, creates table and loads data. Then camel route, runs "select" to pull the data.
Here is the code:
public void configure() throws Exception {
from("timer://timer1?period=1000")
.setBody(constant("select * from Employee"))
.to("jdbc:dataSource")
.split().simple("${body}")
.log("process row ${body}")

I want to create a flow using DSL. The flow is from the adapter, message will flow to channel.
#Bean
public IntegrationFlow sftpInboundFlow() {
prepareSftpServer();
return IntegrationFlows
.from(Sftp.inboundAdapter(this.sftpSessionFactory).getId("SftpInboundAdapter")
.preserveTimestamp(true)
.remoteDirectory("sftpSource")
.regexFilter(".*\\.txt$")
.localFilenameExpression("#this.toUpperCase() + '.a'").localDirectory(file).channel(MessageChannels.queue("sftpInboundResultChannel"))
.get());
}
Not sure of compilation error at getId() method . tried to convert from Java 8 lambda to Java 7
I think you want to add an id attribute for your component to register it with that bean name in the application context. You config must look like:
return IntegrationFlows
.from(Sftp.inboundAdapter(this.sftpSessionFactory)
.preserveTimestamp(true)
.remoteDirectory("sftpSource")
.regexFilter(".*\\.txt$")
.localFilenameExpression("#this.toUpperCase() + '.a'")
.localDirectory(file),
new Consumer<SourcePollingChannelAdapterSpec>() {
#Override
public void accept(SourcePollingChannelAdapterSpec e) {
e.id("SftpInboundAdapter");
}
})
.channel(MessageChannels.queue("sftpInboundResultChannel"))
.get();
There is no such a getId(String) method.
Yes I'll fix its JavaDocs eventuelly, but you are facing really compilation error, hence wrong language usage.
