It is important to understand certain limitations when it comes to using it. + +SpEL gives you access to the current Message as well as the Application Context you are running in. +However it is important to understand what type of data SpEL can see especially in the context of the incoming Message. +From the broker, the message arrives in a form of a byte[]. It is then transformed to a `Message` by the binders where as you can see the payload of the message maintains its raw form. The headers of the message are ``, where values are typically another primitive or a collection/array of primitives, hence Object. +That is because binder does not know the required input type as it has no access to the user code (function). So effectively binder delivered an envelope with the payload and some readable meta-data in the form of message headers, just like the letter delivered by mail. +This means that while accessing payload of the message is possible you will only have access to it as raw data (i.e., byte[]). And while it may be very common for developers to ask for ability to have SpEL access to fields of a payload object as concrete type (e.g., Foo, Bar etc), you can see how difficult or even impossible would it be to achieve. +Here is one example to demonstrate the problem; Imagine you have a routing expression to route to different functions based on payload type. This requirement would imply payload conversion from byte[] to a specific type and then applying the SpEL. However, in order to perform such conversion we would need to know the actual type to pass to converter and that comes from functions signature which we don’t know which one. A better approach to solve this requirement would be to pass the type information as message headers (e.g., `application/json;type=foo.bar.Baz` ). You’ll get a clear readable String value that could be accessed and evaluated in a year and easy to read SpEL expression. + +Additionally it is considered very bad practice to use payload for routing decisions, since the payload is considered to be privileged data - data only to be read by its final recipient. Again, using the mail delivery analogy you would not want the mailman to open your envelope and read the contents of the letter to make some delivery decisions. The same concept applies here, especially when it is relatively easy to include such information when generating a Message. It enforces certain level of discipline related to the design of data to be transmitted over the network and which pieces of such data can be considered as public and which are privileged. diff --git a/docs/src/main/asciidoc/spring-cloud-stream.adoc b/docs/src/main/asciidoc/spring-cloud-stream.adoc index f685d6cf5..42dd8c1de 100644 --- a/docs/src/main/asciidoc/spring-cloud-stream.adoc +++ b/docs/src/main/asciidoc/spring-cloud-stream.adoc @@ -2398,9 +2398,9 @@ public MessageSourceCustomizer sourceCustomizer() { These properties are exposed via `org.springframework.cloud.stream.binder.ProducerProperties` The following binding properties are available for output bindings only and must be prefixed with `spring.cloud.stream.bindings..producer.` -(for example, `spring.cloud.stream.bindings.func-out-0.producer.partitionKeyExpression=payload.id`). +(for example, `spring.cloud.stream.bindings.func-out-0.producer.partitionKeyExpression=headers.id`). -Default values can be set by using the prefix `spring.cloud.stream.default.producer` (for example, `spring.cloud.stream.default.producer.partitionKeyExpression=payload.id`). +Default values can be set by using the prefix `spring.cloud.stream.default.producer` (for example, `spring.cloud.stream.default.producer.partitionKeyExpression=headers.id`). autoStartup:: Signals if this consumer needs to be started automatically @@ -2719,14 +2719,14 @@ You can configure an output binding to send partitioned data by setting one and For example, the following is a valid and typical configuration: ---- -spring.cloud.stream.bindings.func-out-0.producer.partitionKeyExpression=payload.id +spring.cloud.stream.bindings.func-out-0.producer.partitionKeyExpression=headers.id spring.cloud.stream.bindings.func-out-0.producer.partitionCount=5 ---- Based on that example configuration, data is sent to the target partition by using the following logic.

If you have more then one bean of type `org.springframework.cloud.stream.binder.PartitionKeyExtractorStrategy` available in the Application Context, you can further filter it by specifying its name with the `partitionKeyExtractorName` property, as shown in the following example: From b97badcf2df211be3fe4efb38682718478aa3372 Mon Sep 17 00:00:00 2001 From: Oleg Zhurakousky Date: Wed, 1 Dec 2021 11:03:50 +0100 Subject: [PATCH 06/27] Fix spelling errors in doc --- docs/src/main/asciidoc/preface.adoc | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/docs/src/main/asciidoc/preface.adoc b/docs/src/main/asciidoc/preface.adoc index 259a18adb..5b1c690fc 100644 --- a/docs/src/main/asciidoc/preface.adoc +++ b/docs/src/main/asciidoc/preface.adoc @@ -174,13 +174,13 @@ and annotation-based programming model. == Spring Expression Language (SpEL) in the context of Streaming data -Throwout this reference manual you will encounter many features and examples where you can utilize Spring Expression Language (SpEL).

It is important to understand certain limitations when it comes to using it. SpEL gives you access to the current Message as well as the Application Context you are running in. However it is important to understand what type of data SpEL can see especially in the context of the incoming Message. From the broker, the message arrives in a form of a byte[]. It is then transformed to a `Message` by the binders where as you can see the payload of the message maintains its raw form. The headers of the message are ``, where values are typically another primitive or a collection/array of primitives, hence Object. That is because binder does not know the required input type as it has no access to the user code (function). So effectively binder delivered an envelope with the payload and some readable meta-data in the form of message headers, just like the letter delivered by mail. This means that while accessing payload of the message is possible you will only have access to it as raw data (i.e., byte[]). And while it may be very common for developers to ask for ability to have SpEL access to fields of a payload object as concrete type (e.g., Foo, Bar etc), you can see how difficult or even impossible would it be to achieve. -Here is one example to demonstrate the problem; Imagine you have a routing expression to route to different functions based on payload type. This requirement would imply payload conversion from byte[] to a specific type and then applying the SpEL. However, in order to perform such conversion we would need to know the actual type to pass to converter and that comes from functions signature which we don’t know which one. A better approach to solve this requirement would be to pass the type information as message headers (e.g., `application/json;type=foo.bar.Baz` ). You’ll get a clear readable String value that could be accessed and evaluated in a year and easy to read SpEL expression. +Here is one example to demonstrate the problem; Imagine you have a routing expression to route to different functions based on payload type.

You’ll get a clear readable String value that could be accessed and evaluated in a year and easy to read SpEL expression. Additionally it is considered very bad practice to use payload for routing decisions, since the payload is considered to be privileged data - data only to be read by its final recipient. Again, using the mail delivery analogy you would not want the mailman to open your envelope and read the contents of the letter to make some delivery decisions. The same concept applies here, especially when it is relatively easy to include such information when generating a Message. It enforces certain level of discipline related to the design of data to be transmitted over the network and which pieces of such data can be considered as public and which are privileged.

The use of annotations in this case is mandatory. In this case the - * {@link StreamListener} annotation must not specify a value.
    • - *
  • By setting an {@link Input} bound target as the annotation value of - * {@link StreamListener} and using - * {@link org.springframework.messaging.handler.annotation.SendTo} on the method for - * the return type (if applicable). In this case the method must have exactly one - * parameter, corresponding to an input. - *
    • - *
- * - * An example of declarative method signature using the former idiom is as follows: - * - * 
- * @StreamListener
- * public @Output("joined") Flux<String> join(
- *       @Input("input1") Flux<String> input1,
- *       @Input("input2") Flux<String> input2) {
- *   // ... join the two input streams via functional operators
- * }
- *
- * - * An example of declarative method signature using the latter idiom is as follows: - * - * 
- * @StreamListener(Processor.INPUT)
- * @SendTo(Processor.OUTPUT)
- * public Flux<String> convert(Flux<String> input) {
- *     return input.map(String::toUppercase);
- * }
- *
- * - * Declarative methods are invoked only once, when the context is refreshed. - * - *

Individual message handler mode

- * - * Non declarative methods are treated as message handler based, and are invoked for each - * incoming message received from that target. In this case, the method can have a - * flexible signature, as described by {@link MessageMapping}. - * - * If the method returns a {@link org.springframework.messaging.Message}, the result will - * be automatically sent to a binding target, as follows: - *
    - *
  • A result of the type {@link org.springframework.messaging.Message} will be sent - * as-is
    • - *
  • All other results will become the payload of a - * {@link org.springframework.messaging.Message}
    • - *
- * - * The output binding target where the return message is sent is determined by consulting - * in the following order: - *
    - *
  • The {@link org.springframework.messaging.MessageHeaders} of the resulting - * message.
    • - *
  • The value set on the - * {@link org.springframework.messaging.handler.annotation.SendTo} annotation, if - * present
    • - *
- * - * An example of individual message handler signature is as follows: - * - * 
- * @StreamListener(Processor.INPUT)
- * @SendTo(Processor.OUTPUT)
- * public String convert(String input) {
- * 		return input.toUppercase();
- * }

For backward -compatibility you can still bring `spring-cloud-stream-reactive` from previous versions. +Throughout this reference manual you will encounter many features and examples where you can utilize Spring Expression Language (SpEL). It is important to understand certain limitations when it comes to using it. +SpEL gives you access to the current Message as well as the Application Context you are running in. +However it is important to understand what type of data SpEL can see especially in the context of the incoming Message. +From the broker, the message arrives in a form of a byte[]. It is then transformed to a `Message` by the binders where as you can see the payload of the message maintains its raw form. The headers of the message are ``, where values are typically another primitive or a collection/array of primitives, hence Object. +That is because binder does not know the required input type as it has no access to the user code (function). So effectively binder delivered an envelope with the payload and some readable meta-data in the form of message headers, just like the letter delivered by mail. +This means that while accessing payload of the message is possible you will only have access to it as raw data (i.e., byte[]). And while it may be very common for developers to ask for ability to have SpEL access to fields of a payload object as concrete type (e.g., Foo, Bar etc), you can see how difficult or even impossible would it be to achieve. +Here is one example to demonstrate the problem; Imagine you have a routing expression to route to different functions based on payload type. This requirement would imply payload conversion from byte[] to a specific type and then applying the SpEL. However, in order to perform such conversion we would need to know the actual type to pass to converter and that comes from function's signature which we don’t know which one. A better approach to solve this requirement would be to pass the type information as message headers (e.g., `application/json;type=foo.bar.Baz` ). You’ll get a clear readable String value that could be accessed and evaluated in a year and easy to read SpEL expression. -[[spring-cloud-stream-preface-notable-deprecations]] -=== Notable Deprecations and Removals - -- Annotation-based programming model is now fully removed.

Again, using the mail delivery analogy you would not want the mailman to open your envelope and read the contents of the letter to make some delivery decisions. The same concept applies here, especially when it is relatively easy to include such information when generating a Message. It enforces certain level of discipline related to the design of data to be transmitted over the network and which pieces of such data can be considered as public and which are privileged. = Appendices [appendix] diff --git a/docs/src/main/asciidoc/_configprops.adoc b/docs/src/main/asciidoc/_configprops.adoc index 45e42323f..55f3103e3 100644 --- a/docs/src/main/asciidoc/_configprops.adoc +++ b/docs/src/main/asciidoc/_configprops.adoc @@ -9,6 +9,7 @@ |spring.cloud.stream.dynamic-destinations | `[]` | A list of destinations that can be bound dynamically.

Noticed the plural in the property names allowing you to define multiple bindings by simply using `;` as a delimiter. +Just look at the following test case as an example: + +---- +@Test +public void testExplicitBindings() { + try (ConfigurableApplicationContext context = new SpringApplicationBuilder( + TestChannelBinderConfiguration.getCompleteConfiguration(EmptyConfiguration.class)) + .web(WebApplicationType.NONE) + .run("--spring.jmx.enabled=false", + "--spring.cloud.stream.input-bindings=fooin;barin", + "--spring.cloud.stream.output-bindings=fooout;barout")) { + + assertThat(context.getBean("fooin-in-0", MessageChannel.class)).isNotNull(); + assertThat(context.getBean("barin-in-0", MessageChannel.class)).isNotNull(); + assertThat(context.getBean("fooout-out-0", MessageChannel.class)).isNotNull(); + assertThat(context.getBean("barout-out-0", MessageChannel.class)).isNotNull(); + } +} + +@EnableAutoConfiguration +@Configuration +public static class EmptyConfiguration { +} +---- + +As you can see we have declared two input bindings and two output bindings while our configuration had no functions defined, yet we were able to successfully create these bindings and access their corresponding channels. + +The rest of the binding rules that apply to implicit bindings apply here as well (for example, you can see that `fooin` turned into `fooin-in-0` binding/channel etc). + + === Producing and Consuming Messages You can write a Spring Cloud Stream application by simply writing functions and exposing them as `@Bean`s. diff --git a/spring-cloud-stream/src/main/java/org/springframework/cloud/stream/config/BindingServiceProperties.java b/spring-cloud-stream/src/main/java/org/springframework/cloud/stream/config/BindingServiceProperties.java index fcebda21f..015d5dea1 100644 --- a/spring-cloud-stream/src/main/java/org/springframework/cloud/stream/config/BindingServiceProperties.java +++ b/spring-cloud-stream/src/main/java/org/springframework/cloud/stream/config/BindingServiceProperties.java @@ -61,12 +61,26 @@ public class BindingServiceProperties private static final int DEFAULT_BINDING_RETRY_INTERVAL = 30; /** - * A colon delimited string representing the names of the sources based on which source bindings will be created. + * A semi-colon delimited string representing the names of the sources based on which source bindings will be created. * This is primarily to support cases where source binding may be required without providing a corresponding Supplier. * (e.g., for cases where the actual source of data is outside of scope of spring-cloud-stream - HTTP -> Stream) + * @deprecated use {@link #outputBindings} */ + @Deprecated private String source; + /** + * A semi-colon delimited string to explicitly define input bindings (specifically for cases when there + * is no implicit trigger to create such bindings such as Function, Supplier or Consumer). + */ + private String inputBindings; + + /** + * A semi-colon delimited string to explicitly define output bindings (specifically for cases when there + * is no implicit trigger to create such bindings such as Function, Supplier or Consumer). + */ + private String outputBindings; + /** * The instance id of the application: a number from 0 to instanceCount-1.

And here you're also benefiting from +the dynamic features of `StreamBridge` where if `myBinding` doesn't exist it will be created automatically and cached, otherwise existing binding will be used. NOTE: Caching dynamic destinations (bindings) could result in memory leaks in the event there are many dynamic destinations. To have some level of control we provide a self-evicting caching mechanism for output bindings with default cache size of 10. This means that if your dynamic destination size goes above that number, there is a possibility that an existing binding will be evicted and thus would need to be recreated which could cause minor performance degradation. You can increase the cache size via `spring.cloud.stream.dynamic-destination-cache-size` property setting it to the desired value.
