获取配置的规则

• 假设:

spring.cloud.zookeeper.config.root=xxxx ;

spring.application.name=abc

• zk 路径:

/xxxx/abc/com/gabo/username

• 取值:

//不能动态更新值,需要重启项目

@Value("${com.xxx.username}")

@Data
//可以动态修改值,不需要重启
@ConfigurationProperties(prefix = "datasource")
public class Myconf2 {
    private String url;
    private String pass;
}

@SpringBootApplication
@EnableDiscoveryClient
//@EnableConfigServer
@EnableAutoConfiguration
@EnableConfigurationProperties({Myconf.class,Myconf2.class})
//支持多个配置类 @EnableConfigurationProperties({xxx.class,abc.class})
public class ZookeeperApplication {
    public static void main(String[] args) {
        SpringApplication.run(ZookeeperApplication.class, args);
    }
}
