### Feign 支持
|
||||
|
||||
DOING
|
||||
Sentinel 适配了 https://github.com/OpenFeign/feign[Feign] 组件。如果想使用，除了引入 `sentinel-starter` 的依赖外还需要 3 个步骤：
|
||||
|
||||
* 配置文件打开 sentinel 对 feign 的支持：`feign.sentinel.enabled=true`
|
||||
* 加入 `feign starter` 依赖触发 `sentinel starter` 的配置类生效：
|
||||
```xml
|
||||
<dependency>
|
||||
<groupId>org.springframework.cloud</groupId>
|
||||
<artifactId>spring-cloud-starter-openfeign</artifactId>
|
||||
</dependency>
|
||||
```
|
||||
* `feign` 内部的 `loadbalance` 功能依赖 Netflix 的 `ribbon` 模块(如果不使用 `loadbalance` 功能可不引入)：
|
||||
```xml
|
||||
<dependency>
|
||||
<groupId>org.springframework.cloud</groupId>
|
||||
<artifactId>spring-cloud-starter-netflix-ribbon</artifactId>
|
||||
</dependency>
|
||||
```
|
||||
|
||||
这是一个 `FeignClient` 对应的接口：
|
||||
|
||||
```java
|
||||
@FeignClient(name = "service-provider", fallback = EchoServiceFallback.class, configuration = FeignConfiguration.class)
|
||||
public interface EchoService {
|
||||
@RequestMapping(value = "/echo/{str}", method = RequestMethod.GET)
|
||||
String echo(@PathVariable("str") String str);
|
||||
}
|
||||
|
||||
class FeignConfiguration {
|
||||
@Bean
|
||||
public EchoServiceFallback echoServiceFallback() {
|
||||
return new EchoServiceFallback();
|
||||
}

}

class EchoServiceFallback implements EchoService {

@Override

|
||||
return "echo fallback";
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
NOTE: Feign 对应的接口中的资源名策略定义：httpmethod:http://requesturl
|
||||
|
||||
`EchoService` 接口中方法 `echo` 对应的资源名为 `GET:http://service-provider/echo/{str}`。
|
||||
|
||||
请注意：`@FeignClient` 注解中的所有属性，Sentinel 都做了兼容。

# RocketMQ Example
|
||||
|
||||
## Project Instruction
|
||||
|
||||
This example illustrates how to use RocketMQ Binder implement pub/sub messages for Spring Cloud applications.
|
||||
|
||||
[RocketMQ](https://rocketmq.apache.org/) is a distributed messaging and streaming platform with low latency, high performance and reliability, trillion-level capacity and flexible scalability.
|
||||
|
||||
Before we start the demo, let's look at Spring Cloud Stream.
|
||||
|
||||
Spring Cloud Stream is a framework for building message-driven microservice applications. Spring Cloud Stream builds upon Spring Boot to create standalone, production-grade Spring applications and uses Spring Integration to provide connectivity to message brokers. It provides opinionated configuration of middleware from several vendors, introducing the concepts of persistent publish-subscribe semantics, consumer groups, and partitions.
|
||||
|
||||
There are two concepts in Spring Cloud Stream: Binder 和 Binding.
|
||||
|
||||
* Binder: A strategy interface used to bind an app interface to a logical name.
|
||||
|
||||
Binder Implementations includes `KafkaMessageChannelBinder` of kafka, `RabbitMessageChannelBinder` of RabbitMQ and `RocketMQMessageChannelBinder` of `RocketMQ`.
|
||||
|
||||
* Binding: Including Input Binding and Output Binding.
|
||||
|
||||
Binding is Bridge between the external messaging systems and application provided Producers and Consumers of messages.
|
||||
|
||||
This is a overview of Spring Cloud Stream.
|
||||
|
||||
|
||||
|
||||
## Demo
|
||||
|
||||
### Integration with RocketMQ Binder
|
||||
|
||||
Before we start the demo, let's learn how to Integration with RocketMQ Binder to a Spring Cloud application.
|
||||
|
||||
**Note: This section is to show you how to connect to Sentinel. The configurations have been completed in the following example, so you don't need modify the code any more.**
|
||||
|
||||
1. Add dependency spring-cloud-starter-stream-rocketmq in the pom.xml file in your Spring Cloud project.
|
||||
|
||||
```xml
|
||||
<dependency>
|
||||
<groupId>org.springframework.cloud</groupId>
|
||||
<artifactId>spring-cloud-starter-stream-rocketmq</artifactId>
|
||||
</dependency>
|
||||
```
|
||||
|
||||
2. Configure Input and Output Binding and cooperate with `@EnableBinding` annotation
|
||||
|
||||
```java
|
||||
@SpringBootApplication
|
||||
@EnableBinding({ Source.class, Sink.class })
|
||||
public class RocketMQApplication {
|
||||
public static void main(String[] args) {
|
||||
SpringApplication.run(RocketMQApplication.class, args);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Configure Binding:
|
||||
```properties
|
||||
# configure the nameserver of rocketmq
|
||||
spring.cloud.stream.rocketmq.binder.namesrv-addr=127.0.0.1:9876
|
||||
# configure the output binding named output
|
||||
spring.cloud.stream.bindings.output.destination=test-topic
|
||||
spring.cloud.stream.bindings.output.content-type=application/json
|
||||
# configure the input binding named input
|
||||
spring.cloud.stream.bindings.input.destination=test-topic
|
||||
spring.cloud.stream.bindings.input.content-type=application/json
|
||||
spring.cloud.stream.bindings.input.group=test-group
|
||||
|
||||
```
|
||||
|
||||
3. pub/sub messages
|
||||
|
||||
### Download and Startup RocketMQ
|
||||
|
||||
You should startup Name Server and Broker before using RocketMQ Binder.
|
||||
|
||||
1. Download [RocketMQ](https://www.apache.org/dyn/closer.cgi?path=rocketmq/4.3.2/rocketmq-all-4.3.2-bin-release.zip) and unzip it.
|
||||
|
||||
2. Startup Name Server
|
||||
|
||||
```bash
|
||||
sh bin/mqnamesrv
|
||||
```
|
||||
|
||||
3. Startup Broker
|
||||
|
||||
```bash
|
||||
sh bin/mqbroker -n localhost:9876
|
||||
```
|
||||
|
||||
4. Create topic: test-topic
|
||||
|
||||
```bash
|
||||
sh bin/mqadmin updateTopic -n localhost:9876 -c DefaultCluster -t test-topic
|
||||
```
|
||||
|
||||
### Start Application
|
||||
|
||||
1. Add necessary configurations to file `/src/main/resources/application.properties`.
|
||||
|
||||
```properties
|
||||
spring.application.name=rocketmq-example
|
||||
server.port=28081
|
||||
```
|
||||
|
||||
2. Start the application in IDE or by building a fatjar.
|
||||
|
||||
1. Start in IDE: Find main class `RocketMQApplication`, and execute the main method.
|
||||
2. Build a fatjar: Execute command `mvn clean package` to build a fatjar, and run command `java -jar rocketmq-example.jar` to start the application.
|
||||
|
||||
|
||||
### Message Handle
|
||||
|
||||
Using the binding named output and sent messages to `test-topic` topic.
|
||||
|
||||
And using two input bindings to subscribe messages.
|
||||
|
||||
* input1: subscribe the message of `test-topic` topic and consume ordered messages(all messages should in the same MessageQueue if you want to consuming ordered messages).
|
||||
|
||||
* input2: subscribe the message of `test-topic` topic and consume concurrent messages which tags is `tagStr`, the thread number in pool is 20 in Consumer side.
|
||||
|
||||
see the configuration below:
|
||||
|
||||
```properties
|
||||
spring.cloud.stream.rocketmq.binder.namesrv-addr=127.0.0.1:9876
|
||||
|
||||
spring.cloud.stream.bindings.output.destination=test-topic
|
||||
spring.cloud.stream.bindings.output.content-type=application/json
|
||||
|
||||
spring.cloud.stream.bindings.input1.destination=test-topic
|
||||
spring.cloud.stream.bindings.input1.content-type=text/plain
|
||||
spring.cloud.stream.bindings.input1.group=test-group1
|
||||
spring.cloud.stream.rocketmq.bindings.input1.consumer.orderly=true
|
||||
|
||||
spring.cloud.stream.bindings.input2.destination=test-topic
|
||||
spring.cloud.stream.bindings.input2.content-type=text/plain
|
||||
spring.cloud.stream.bindings.input2.group=test-group2
|
||||
spring.cloud.stream.rocketmq.bindings.input2.consumer.orderly=false
|
||||
spring.cloud.stream.rocketmq.bindings.input2.consumer.tags=tagStr
|
||||
spring.cloud.stream.bindings.input2.consumer.concurrency=20
|
||||
|
||||
```
|
||||
|
||||
#### Pub Messages
|
||||
|
||||
Using MessageChannel to send messages:
|
||||
|
||||
```java
|
||||
public class ProducerRunner implements CommandLineRunner {
|
||||
@Autowired
|
||||
private MessageChannel output;
|
||||
@Override
|
||||
public void run(String... args) throws Exception {
|
||||
Map<String, Object> headers = new HashMap<>();
|
||||
headers.put(MessageConst.PROPERTY_TAGS, "tagStr");
|
||||
Message message = MessageBuilder.createMessage(msg, new MessageHeaders(headers));
|
||||
output.send(message);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Or you can using the native API of RocketMQ to send messages:
|
||||
|
||||
```java
|
||||
public class RocketMQProducer {
|
||||
DefaultMQProducer producer = new DefaultMQProducer("producer_group");
|
||||
producer.setNamesrvAddr("127.0.0.1:9876");
|
||||
producer.start();
|
||||
|
||||
Message msg = new Message("test-topic", "tagStr", "message from rocketmq producer".getBytes());
|
||||
producer.send(msg);
|
||||
}
|
||||
```
|
||||
|
||||
#### Sub Messages
|
||||
|
||||
Using `@StreamListener` to receive messages:
|
||||
|
||||
```java
|
||||
@Service
|
||||
public class ReceiveService {
|
||||
|
||||
@StreamListener("input1")
|
||||
public void receiveInput1(String receiveMsg) {
|
||||
System.out.println("input1 receive: " + receiveMsg);
|
||||
}
|
||||
|
||||
@StreamListener("input2")
|
||||
public void receiveInput2(String receiveMsg) {
|
||||
System.out.println("input2 receive: " + receiveMsg);
|
||||
}
|
||||
|
||||
}
|
||||
```
|
||||
|
||||
## Endpoint
|
||||
|
||||
Add dependency `spring-cloud-starter-stream-rocketmq` to your pom.xml file, and configure your endpoint security strategy.
|
||||
|
||||
* Spring Boot1.x: Add configuration `management.security.enabled=false`
|
||||
* Spring Boot2.x: Add configuration `management.endpoints.web.exposure.include=*`
|
||||
|
||||
To view the endpoint information, visit the following URLS:
|
||||
* Spring Boot1.x: Sentinel Endpoint URL is http://127.0.0.1:18083/rocketmq_binder.
|
||||
* Spring Boot2.x: Sentinel Endpoint URL is http://127.0.0.1:18083/actuator/rocketmq-binder.
|
||||
|
||||
Endpoint will metrics some data like last send timestamp, sending or receive message successfully times or unsuccessfully times.
|
||||
|
||||
```json
|
||||
{
|
||||
"runtime": {
|
||||

```
|
||||
|
||||
Note: You should add [metrics-core dependency](https://mvnrepository.com/artifact/io.dropwizard.metrics/metrics-core) if you want to see metrics data. endpoint will show warning information if you don't add that dependency:
|
||||
|
||||
```json
|
||||
{
|
||||
"warning": "please add metrics-core dependency, we use it for metrics"
|
||||
}
|
||||
```
