1.依赖
<!--引入consul-->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-consul-discovery</artifactId>
</dependency>
<!--引入健康检查-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-config</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
2.配置文件
application.properties
server.port=9991
spring.application.name=configclient
spring.cloud.consul.host=localhost
spring.cloud.consul.port=8500
spring.cloud.consul.discovery.service-name=${spring.application.name}
management.endpoints.web.exposure.include=*
name=${name}
bootstrap.properties
spring.cloud.config.name=sem spring.cloud.config.profile=pro spring.cloud.config.uri=http://127.0.0.1:9999/ spring.cloud.config.label=
3.启动注解
@SpringBootApplication
public class ConfigclientApplication {
public static void main(String[] args) {
SpringApplication.run(ConfigclientApplication.class, args);
}
}
4.controller
@RestController
@RefreshScope
public class TestController {
@Value("${name}")
private String name;
@RequestMapping("/test")
public String hello() {
return name;
}
}
5.刷新
SVN配置文件修改提交后，configclient需要post发送刷新请求 URL：http://127.0.0.1:9991/actuator/refresh，再次访问带有@RefreshScope注解的controller配置文件修改后的值才能被重新加载。
