一. 前言
获取Eureka实例
|
1
2
3
4
|
public String serviceUrl() { InstanceInfo instance = discoveryClient.getNextServerFromEureka("STORES", false);
return instance.getHomePageUrl();
} |
步骤：
二. 导入包
pom.xml
|

|
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-eureka</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-hystrix</artifactId>
</dependency>
|
三. 修改启动Application

@EnableCircuitBreaker@EnableDiscoveryClientpublic class HellloMain { @Bean
@LoadBalanced
RestTemplate restTemplate() {
return new RestTemplate();
}
public static void main(String[] args) {
SpringApplication.run(HelloMain.class, args);
}
} |
四. 业务使用

private int xxxx(String body) { RestTemplate restTemplate = new RestTemplate();
HttpHeaders headers = new HttpHeaders();
MediaType type = MediaType.parseMediaType("application/json");
headers.setContentType(type);
HttpEntity<String> formEntity = new HttpEntity<String>(body, headers);
String result = restTemplate.postForObject(getEurkaClient("hello-module"),
formEntity,
String.class);
return 0;
} |
|

|
public String getEurkaClient(String end) { InstanceInfo instance = discoveryClient.getNextServerFromEureka("smarthome-phihome", false);
return instance.getHomePageUrl() + end;
} |
这样就可以在应用程序之间互相调用
