第一個pom文件引入<dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-eureka</artifactId>
</dependency>第二步把微服務注冊到Eureka里面去,在啟動類里面加上注解,@EnableEurekaClient@MapperScan(value="com.learn.cloud.mapper")
@EnableEurekaClient
@SpringBootApplication
public class MicroserviceSimpleProviderUserApplication {public static void main(String[] args) {SpringApplication.run(MicroserviceSimpleProviderUserApplication.class, args);}
}@EnableDiscoverClient,這兩個注解有什么區別呢,@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Inherited
@EnableDiscoveryClient
public @interface EnableEurekaClient {}只是他非常的語義化,@EnableDiscoveryClient這個可以使用到ZK和Consul,https://cloud.spring.io/spring-cloud-static/Camden.SR1/#netflix-eureka-client-startermaven生成jar，提示沒有“沒有主清單屬性”https://www.jianshu.com/p/fd5bd865785210.40.8.152:8761vim /etc/profile添加如下內容：JAVA_HOME根據實際目錄來
JAVA_HOME=/usr/local/software/jdk1.8.0_151
CLASSPATH=JAVAHOME/lib/PATH=PATH:$JAVA_HOME/bin
export PATH JAVA_HOME CLASSPATHsource /etc/profile10.40.8.152:8761localhost:876110.40.8.144:7900/eureka-instanceInstanceInfo getNextServerFromEureka(String virtualHostname, boolean secure);10.40.8.144:7900/instance-info{"host":"10.40.8.144","port":7900,"metadata":{},"uri":"http://10.40.8.144:7900","secure":false,"serviceId":"microservice-simple-provider-user"}{"host":"10.40.8.144","port":7900,"metadata":{},"uri":"http://10.40.8.144:7900","secure":false,"serviceId":"microservice-simple-provider-user"
