SpringCloud用Zookeeper搭建配置中心的方法

<!-- 提供zookeeper整合的包 -->
<dependency>
  <groupId>org.springframework.cloud</groupId>
  <artifactId>spring-cloud-starter-zookeeper-config</artifactId>
</dependency>
<!-- springboot 提供监听的 -->
<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

#指定zookeeper的地址,多个用逗号拼接
spring.cloud.zookeeper.connect-string=192.168.100.0:2181
#指定springcloud 读取zookeeper路径的开始位置
spring.cloud.zookeeper.config.root=springcloud
#开始zk的配置
spring.cloud.zookeeper.config.enabled=true
#zk会在你指定的根目录下寻找以这个项目名命名的目录下的配置
spring.application.name=service_config

//不能动态更新值,需要重启项目
@Value("${com.xxx.username}")
 public String username ;

//可以动态修改值,不需要重启
@ConfigurationProperties(prefix = "com.xxx")
public class UserInfo {
  public String username ;
  public String getUsername() {
    return username;
  }
  public void setUsername(String username) {
    this.username = username;
  }
}

@SpringBootApplication
//支持多个配置类
@EnableConfigurationProperties({xxx.class,abc.class})
public class ServiceConfigApplication {

  public static void main(String[] args) {
    SpringApplication.run(ServiceConfigApplication.class, args);
  }
}

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

spring.application.name=abc

@value(${com.gabo.username})
