1. Create a Maven project, ArtificatId is microservice-sample-consumer-alarm
2. Add dependencies
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.4.3.RELEASE</version>
</parent>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<java.version>1.8</java.version>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
</dependencies>
<!-- Introduce the dependency of spring cloud-->
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Camden.SR4</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
<!-- Add spring-boot maven plugin -->
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
3. Create an entity class
4. Create a startup class
@SpringBootApplication
public class ConsumerAlarmApplication {
@Bean
public RestTemplate restTemplate() {
return new RestTemplate();
}
public static void main(String[] args) {
SpringApplication.run(ConsumerAlarmApplication.class, args);
}
}
The role of @ is to instantiate a bean and name it with the name of the method, which is equivalent to:
RestTemplate restTemplate = new RestTemplate()
5. Create a Controller and use RestTemplate to request production microservices
@RestController
public class AlarmConsumerController {
@Autowired
private RestTemplate restTemplate;
@GetMapping("/alarm/findAll")
public User findById() {
return this.restTemplate.getForObject("http://localhost:8000" , AlarmBean.class);
}
}
6. Write application.yml
server: port: 8010
